The prime factors of 13195 are 5, 7, 13 and 29. What is the largest prime factor of the number 600851475143 ?

The cos(θ) is approximately 0.92.

We can use the Pythagorean identity to find cos(θ).

The Pythagorean identity states that [tex]sin^2[/tex](θ) + [tex]cos^2[/tex] (θ) = 1.

Given sin(θ) = 2/5, we can substitute this value into the equation:

[tex](2/5)^2 + cos^2(\pi) = 14/25 + cos^2(\pi) = 1[/tex]

Now, we can solve for

[tex]cos^2 (\theta): cos^2[\theta] = 1 - 4/25cos^2(\theta) = 25/25 - 4/25[tex]cos^2(\theta) = 21/25[/tex]

Taking the square root of both sides, we get:

cos(θ) = ± [tex]\sqrt(21/25)[/tex]

Since θ is in the first quadrant, we take the positive value:cos(θ) = sqrt(21/25)

Simplifying further:

cos(θ) = [tex]\sqrt(21)/\sqrt(25)[/tex]cos(θ) = sqrt(21)/5

Approximating the value of [tex]\sqrt(21)[/tex] to two decimal places:cos(θ) ≈ 0.92

Therefore, cos(θ) is approximately 0.92.

To determine the convergence or divergence of the series ∑(n=1 to infinity) 1/(n^6 - 8), we can use the Comparison Test.

Comparison Test:

If 0 ≤ aₙ ≤ bₙ for all n, and ∑ bₙ converges, then ∑ aₙ also converges. Conversely, if ∑ bₙ diverges, then ∑ aₙ also diverges.

Let's analyze the given series using the Comparison Test:

Consider the series ∑(n=1 to infinity) 1/n^6.

For each term, 1/(n^6 - 8) ≤ 1/n^6 because subtracting 8 from the denominator makes it smaller.

Now, let's analyze the series ∑(n=1 to infinity) 1/n^6 using the p-series test.

p-series Test:

If ∑ 1/n^p, where p > 1, then the series converges. If p ≤ 1, the series diverges.

In our case, p = 6, which is greater than 1. Therefore, the series ∑(n=1 to infinity) 1/n^6 converges.

Since 0 ≤ 1/(n^6 - 8) ≤ 1/n^6, and ∑(n=1 to infinity) 1/n^6 converges, by the Comparison Test, we can conclude that ∑(n=1 to infinity) 1/(n^6 - 8) also converges.

Total number of possible outcomes are 20

The Fundamental Counting Principle is a rule that states that if one event has M outcomes and another event has N outcomes, then the combined events have M*N outcomes. The principle is helpful in determining the number of possible outcomes in an experiment that involves several sub-experiments. Let us see how we can use the Fundamental Counting Principle to determine the total number of possible outcomes in the given scenario:

There are four different battery lives: 1 day, 3 days, 5 days, and 7 days.There are five different colors: silver, green, blue, pink, and black.Using the Fundamental Counting Principle, we can determine the total number of possible outcomes as follows:Total number of possible outcomes = Number of outcomes for battery life * Number of outcomes for color= 4 * 5= 20

To use the Fundamental Counting Principle to determine the total number of possible outcomes, we need to determine the number of outcomes for each sub-experiment. In this case, there are two sub-experiments: battery life and color. For the battery life sub-experiment, there are four different battery lives: 1 day, 3 days, 5 days, and 7 days.

For the color sub-experiment, there are five different colors: silver, green, blue, pink, and black.Using the Fundamental Counting Principle, we can determine the total number of possible outcomes by multiplying the number of outcomes for each sub-experiment. Therefore, the total number of possible outcomes is the product of the number of outcomes for battery life and the number of outcomes for color, which is 4 * 5 = 20.There are 20 total possible outcomes for the Fitness Tracker experiment. The Fundamental Counting Principle is a useful tool in determining the number of possible outcomes in complex experiments that involve several sub-experiments.

The solution to the initial value problem is y(t) = (y0 - (1/17)) cos(4t) + [(y'0 + (1/17))/4] sin(4t) + (1/17) e^(-t).

The characteristic equation for the homogeneous part of the differential equation is r^2 + 16 = 0, which has solutions r = ±4i. Therefore, the general solution to the homogeneous equation is:

y_h(t) = c_1 cos(4t) + c_2 sin(4t)

To find a particular solution to the nonhomogeneous equation, we can use the method of undetermined coefficients. Since the forcing function is e^(-t), a reasonable guess for the particular solution is y_p(t) = Ae^(-t), where A is a constant to be determined. Taking the first and second derivatives of this function, we have:

y_p'(t) = -Ae^(-t)

y_p''(t) = Ae^(-t)

Substituting these expressions into the differential equation, we get:

Ae^(-t) + 16Ae^(-t) = e^(-t)

Simplifying this equation, we get A = 1/17. Therefore, the particular solution is:

y_p(t) = (1/17) e^(-t)

The general solution to the nonhomogeneous equation is then:

y(t) = y_h(t) + y_p(t) = c_1 cos(4t) + c_2 sin(4t) + (1/17) e^(-t)

Using the initial conditions y(0) = y0 and y'(0) = y'0, we can solve for the constants c_1 and c_2:

y(0) = c_1 cos(0) + c_2 sin(0) + (1/17) e^(0) = c_1 + (1/17) = y0

y'(0) = -4c_1 sin(0) + 4c_2 cos(0) - (1/17) e^(0) = 4c_2 - (1/17) = y'0

Solving these equations for c_1 and c_2, we get:

c_1 = y0 - (1/17)

c_2 = (y'0 + (1/17) )/4

Therefore, the solution to the initial value problem is:

y(t) = (y0 - (1/17)) cos(4t) + [(y'0 + (1/17))/4] sin(4t) + (1/17) e^(-t)

the series ∑n=1∞ (5an+1 - 3bn+1) diverges to positive infinity.

Using the given values, we have:

5an+1 = 5an = 5 for all n ≥ 1

3bn+1 = 3(-bn) = -3bn for all n ≥ 1

Therefore, the series can be rewritten as:

∑n=1∞ (5an+1 - 3bn+1) = ∑n=1∞ (5 - 3(-bn)) = ∑n=1∞ (5 + 3bn)

We can rewrite this series as a sum of two separate series:

∑n=1∞ (5 + 3bn) = ∑n=1∞ 5 + ∑n=1∞ (3bn)

The first series is a simple infinite sum of the constant 5, which diverges to positive infinity. The second series is an alternating series, with a1 = -9, and decreasing absolute values. By the alternating series test, this series converges to a limit L, where L is between the partial sums S_n and S_n+1 for any n. In particular, we have:

S_1 = a1 = -9

S_2 = a1 + a2 = -9 + 10 = 1

S_3 = a1 + a2 - a3 = -9 + 10 - 11 = -10

S_4 = a1 + a2 - a3 + a4 = -9 + 10 - 11 + 12 = 2

and so on. It is clear that the partial sums alternate between negative and positive values, and that their magnitudes decrease towards zero. Therefore, the limit L of the series is 0.

Putting it all together, we have:

∑n=1∞ (5 + 3bn) = ∑n=1∞ 5 + ∑n=1∞ (3bn) = ∞ + 0 = ∞

At point P, the gradient is nabla f(1, 3, 1) = (1/2, 1/sqrt(2), sqrt(2)/2).

The rate of change of f at P in the direction of the vector u is D_u f(1, 3, 1) = 9/7sqrt(2).

The gradient of f is defined as the vector of partial derivatives of f with respect to its variables. Hence, we have nabla f(x, y, z) = (∂f/∂x, ∂f/∂y, ∂f/∂z) = (1/sqrt(x+yz), z/sqrt(x+yz), y/sqrt(x+yz)).

Substituting the values of P into this expression, we get nabla f(1, 3, 1) = (1/2, 1/sqrt(2), sqrt(2)/2).

The directional derivative of f at P in the direction of the unit vector u is given by the dot product of the gradient of f at P and the unit vector u, i.e., D_u f(1, 3, 1) = nabla f(1, 3, 1) · u.

Substituting the values of P and u into this expression, we get D_u f(1, 3, 1) = (1/2) * (3/7) + (1/sqrt(2)) * (6/7) + (sqrt(2)/2) * (2/7) = 9/7sqrt(2). Therefore, the rate of change of f at P in the direction of the vector u is 9/7sqrt(2).

By taking the limit of the ratio of the nth term of the series to the corresponding term of the integral and simplifying using L'Hopital's rule, we found that the limit was zero, indicating that the series converges.

To determine whether the series from (n=1) to ([infinity]) of (1/4n - 1) converges, we can use the integral test. This test involves comparing the series to the integral of the corresponding function.

First, we need to find the integral of (1/4n - 1). We can do this by integrating each term separately:

∫(1/4n) dn = (1/4)ln(n)

∫(-1) dn = -n

So the integral of (1/4n - 1) is (1/4)ln(n) - n.

Next, we can compare this integral to the series by taking the limit as n approaches infinity of the ratio of the nth term of the series to the corresponding term of the integral.

lim(n → ∞) [(1/4n - 1) / ((1/4)ln(n) - n)]

Using L'Hopital's rule, we can simplify this to:

Lim(n → ∞) [(1/4n^2) / (1/(4n))]

Which simplifies to:

Lim(n → ∞) (1/n) = 0

Since the limit is zero, we can conclude that the series converges by the integral test.

The given vector a can be represented in 3D space as (0,0,0,0,1,0,0,0,1)^T, where T denotes the transpose.

To apply the rotation, we first represent the rotation matrix R about the y-axis by an angle of 90 degrees as:

R = [0 0 1 0 1 0 -1 0 0;

0 1 0 0 0 0 0 0 1;

-1 0 0 1 0 0 0 0 0]

Multiplying R with a, we get:

Ra = [0 0 1 0 1 0 -1 0 0]^T

This means that a is rotated by 90 degrees around the y-axis.

Next, we apply the scaling along the x-axis. We represent the scaling matrix S as:

S = [2 0 0;

0 1 0;

0 0 1]

Multiplying S with Ra, we get:

SRa = [0 0 2 0 1 0 -2 0 0]^T

This means that Ra is scaled by a factor of 2 along the x-axis.

Thus, the transformation t applied to vector a rotates it by 90 degrees around the y-axis and then scales it by a factor of 2 along the x-axis. Geometrically, this can be visualized as taking the original vector a and rotating it clockwise by 90 degrees about the y-axis, and then stretching it horizontally along the x-axis.

After giving Jimmy one-third of the remaining candy pieces and Selena one-fourth of the remaining candy pieces, Bev is now down to having two-thirds as many as three-quarters as many as twenty-four pieces of candy.

Calculating how much candy is still available after each distribution is necessary if we want to establish how many pieces of candy Bev still possesses. At the beginning, Bev has twenty-four individual bits of candy. After giving Jimmy a third of the candy pieces, the number of pieces that are still remaining may be computed as (2/3) times 24, which is equal to two-thirds of the total amount.

The next thing that happens is that Bev gives Selena a quarter of the remaining candy pieces. We need to multiply the total amount that is still available by one quarter since Selena is entitled to a portion of what is left over after Jimmy has received his part. As a result, the remaining candy pieces can be approximated using the formula (3/4 * (2/3) * 24 after Selena has been given her portion.

The solution to the equation is found to be (3/4) * (2/3) * 24, which is 4 * 8, which equals 32. Therefore, after giving Jimmy one third of the remaining candy pieces and Selena one quarter of the remaining candy pieces, Bev still has 32 pieces of candy left.

The temperature change is the difference between the final temperature and the initial temperature. In this case, the initial temperature is -12, and the final temperature is 25. To find the temperature change, we simply subtract the initial temperature from the final temperature:

25 - (-12) = 37

Therefore, the total change in temperature over the 8-hour period is 37 degrees. It is important to note that we do not know how the temperature changed over the 8-hour period. It could have gradually increased, or it could have changed suddenly. Additionally, we do not know the units of temperature, so it is possible that the temperature is measured in Celsius or Fahrenheit. Nonetheless, the temperature change remains the same, regardless of the units used.

The speed of red light in crown glass is approximately 1.99 x [tex]10^8[/tex] m/s.

a. The speed of violet light in crown glass can be calculated using the formula:

v = c/n

Where,

v is the speed of light in the material,

c is the speed of light in vacuum and

n is the index of refraction of the material for violet light.

Plugging in the values given, we get:

violet light speed in crown glass = c/n

violet light speed in crown glass = c/1.53

Using the value for the speed of light in vacuum,

c = 3.00 x [tex]10^8[/tex] m/s,

We can calculate the speed of violet light in crown glass as:

violet light speed in crown glass = (3.00 x [tex]10^8[/tex] m/s) / 1.53

= 1.96 x [tex]10^8[/tex] m/s

Therefore, the speed of violet light in crown glass is approximately 1.96 x [tex]10^8[/tex] m/s.

b. Similarly, the speed of red light in crown glass can be calculated using the same formula, but with the index of refraction for red light:

red light speed in crown glass = c/n = c/1.51

Using the same value for the speed of light in vacuum and plugging in the value for the index of refraction for red light, we get:

The red light speed in crown glass = (3.00 x [tex]10^8[/tex] m/s) / 1.51 = 1.99 x 10^8 m/s

The series converges by the ratio test

We can use the limit comparison test to determine the convergence or divergence of the series:

Using the comparison series [tex]1/n^2[/tex], we have:

[tex]lim [n\rightarrow \infty] (n^2/(8 + 6n)) * (1/n^2)\\= lim [n\rightarrow \infty] 1/(8/n^2 + 6) \\= 0[/tex]

Since the limit is finite and nonzero, the series converges by the limit comparison test.

Alternatively, we can use the ratio test to determine the convergence or divergence of the series:

Taking the ratio of successive terms, we have:

[tex]|(n+1)^2/(8+6(n+1))| / |n^2/(8+6n)|\\= |(n+1)^2/(8n+14)| * |(8+6n)/n^2|[/tex]

Taking the limit as n approaches infinity, we have:

[tex]lim [n\rightarrow \infty] |(n+1)^2/(8n+14)| * |(8+6n)/n^2|\\= lim [n\rightarrow \infty] ((n+1)/n)^2 * (8+6n)/(8n+14)\\= 1/4[/tex]

Since the limit is less than 1, the series converges by the ratio test.

The formula that relates the coefficient of self-induction l, the energy p stored in an electronic circuit, and the current i is given as: p = (1/2) * l * i^2



To find i, we can rearrange the formula as follows:

i = sqrt(2p/l)

Therefore, if we know the values of p and l, we can easily calculate the value of i using the above formula. It is important to note that the units of measurement for p, l, and i should be consistent in order for the formula to work correctly. For instance, if p is in joules and l is in henrys, then the resulting value of i will be in amps.

The energy (P) stored in an inductor with inductance (L) and current (I) is given by the formula:

P = 0.5 * L * I^2

To find the current (I) when you know the energy (P) and inductance (L), you can rearrange the formula as follows:

I = sqrt(2 * P / L)

This equation allows you to calculate the current in the electronic circuit given the energy stored in the inductor and the inductor's coefficient of self-induction.

The area of the region enclosed by the curves  y = √x, y = x² and x = 2 is 4√2/4  - 8/3

To sketch the finite region enclosed by the curves y = √x, y = x² and x = 2 we can first plot the two functions and the vertical line

The region we are interested in is the shaded area between the two curves and to the left of the line x=2. To find the area of this region, we can integrate the difference between the two functions with respect to x over the interval [0] [2]

Given that Kite ABCD is inscribed in circle E and are tangent to circle A. The radius of circle A is 14 and the radius of circle E is 15.

To find: The length of AD (rounded to the nearest tenth)Solution:Since ABCD is a kite, we can say that the two diagonals of the kite are perpendicular to each other.AD is one of the diagonals of the kite.

We need to find the length of AD to find its area, and then we will equate the area of kite ABCD to the product of its diagonals as a property of kite.

The other diagonal of the kite BD is a chord of circle E.The radius of circle E is 15 cmSo, the length of BD is 30 cm. (as it is the diameter of the circle E)Let's consider a right triangle AOD as shown below:

In triangle AOD,By Pythagoras theorem, we have:OD² + AD² = AO²

The angle of depression from the start of the 3-foot high access ramp to the point 20 feet away along the ground is approximately 5.71 degrees.

The angle of depression is the angle formed between the horizontal line and the line of sight to an object that is lower than the observer's level. In this case, the object is the point at the end of the access ramp, which is 3 feet high and 20 feet away from the observer. To find the angle of depression, we need to use trigonometry.

Let's call the height of the observer's eye level H, and the height of the end point of the access ramp h. We can also call the distance from the observer to the end point of the access ramp d. Using these variables, we can set up a right triangle with the vertical leg being H - h (the difference in height between the observer and the end point of the access ramp), the horizontal leg being d (the distance between the observer and the end point of the access ramp), and the hypotenuse being the line of sight from the observer to the end point of the access ramp.

Using the tangent function, we can find the angle of depression:

tanθ = opposite/adjacent = (H - h)/d

To solve for θ, we can take the inverse tangent of both sides:

θ = tan⁻¹((H - h)/d)

Assuming the observer's eye level is 5 feet above the ground, the angle of depression can be found as:

θ = tan⁻¹((5 - 3)/20) = tan⁻¹(0.1) = 5.71 degrees

We have proved the property ez ew = ez+w.

To prove the property ez ew = ez+w, where z = a + bi and w = c + di, we can use the properties of complex exponentials.

First, let's express ez and ew in their exponential form:

ez = e^(a+bi) = e^a * e^(ib)

ew = e^(c+di) = e^c * e^(id)

Now, we can multiply ez and ew together:

ez ew = (e^a * e^(ib)) * (e^c * e^(id))

Using the properties of exponentials, we can simplify this expression:

ez ew = e^a * e^c * e^(ib) * e^(id)

Now, we can use Euler's formula, which states that e^(ix) = cos(x) + i sin(x), to express the complex exponentials in terms of trigonometric functions:

e^(ib) = cos(b) + i sin(b)

e^(id) = cos(d) + i sin(d)

Substituting these values back into the expression, we get:

ez ew = e^a * e^c * (cos(b) + i sin(b)) * (cos(d) + i sin(d))

Using the properties of complex numbers, we can expand and simplify this expression:

ez ew = e^a * e^c * (cos(b)cos(d) - sin(b)sin(d) + i(sin(b)cos(d) + cos(b)sin(d)))

Now, let's express ez+w in exponential form:

ez+w = e^(a+bi+ci+di) = e^((a+c) + (b+d)i)

Using Euler's formula again, we can express this exponential in terms of trigonometric functions:

ez+w = e^(a+c) * (cos(b+d) + i sin(b+d))

Comparing this with our previous expression for ez ew, we can see that they are equal:

ez ew = e^a * e^c * (cos(b)cos(d) - sin(b)sin(d) + i(sin(b)cos(d) + cos(b)sin(d))) = e^(a+c) * (cos(b+d) + i sin(b+d)) = ez+w
