The value of a is 3√3/2 and value of b is 3/2. The solution has obtained using the trigonometry formulas.

What is trigonometry?

The study of the right-angle triangle's sides, angles, and connection is the main focus of the field of mathematics known as "trigonometry." Therefore, it helps to find the unknown or missing angles or sides of a right triangle using the trigonometric formulas, functions, or trigonometric identities. The angles in trigonometry can either be expressed in degrees or radians. The most used trigonometric angles for computations include 0, 30, 45, 60, and 90 degrees.

In the figure, we are given that one angle measures 30° and the other measures 90° and the hypotenuse is 3.

So, using trigonometry, we know that

Cos theta = adjacent side/hypotenuse

And, Cos 30° is √3/2

So,

⇒√3/2 = a/3

⇒a= 3√3/2

Sin theta = opposite side/hypotenuse

And, Sin 30° is 1/2

So,

⇒1/2 = b/3

⇒b= 3/2

Hence, the value of a is 3√3/2 and value of b is 3/2.

Answer:

y = 5/6x - 1/12

Step-by-step explanation:

The slope-intercept form is y = mx + b

10x - 12y = 1

We subtracted 10x from both sides

-12y = -10x + 1

Divided by -12 both sides

y = -10/-12x - 1/12

To simplify we can get

y = 5/6x - 1/12

If Loretta accidentally recorded a deposit of $47.88 as a debit in her register, her check register will differ from the bank statement by $0.

A deposit amount is debited to the check register as an asset, increasing the amount the account holder has in the bank.

It is the bank's responsibility to credit the deposit since it is a liability to them, not an asset.

Under accounting principles, assets are debited while liabilities are credited.  Loretta's debit entry in her register does not constitute an accounting error under the generally-accepted accounting principles.

Thus, Loretta has not committed an accounting error by recording a deposit of $47.88 as a debit in her register, and her register will not differ from the bank statement for this reason.

a. Yes, it is possible for a line (y = mx + b) that passes through the origin (0, 0) to pass through no other rational points. An example of such a line is y = sqrt(2)x. This line passes through the origin (0,0), but the y-coordinate will only be a rational number if the x-coordinate is also a rational number and a perfect square.

b. Yes, it is possible for a line to pass through no rational points. An example of such a line is y = sqrt(2)x + sqrt(3). This line will never pass through any rational points because the y-coordinate will only be a rational number if both x and b are rational numbers and perfect squares, which is not possible in this case.

The given series is convergent and the sum(S) is 5.555.

Consider 10 - 8 + 6.4 - 5.12 + ...

A geometric progression will converge if the common ratio of the series is between -1 and 1.

Here is the common ratio,

r = -8/10

⇒ r = -0.8

Which is -1 < -0.8 < 1.

Hence, the given series is convergent.

Sum of series = S = a/(1 - r)

Here, first term(a) = 10,

The value of the integral can be calculated by using the simple rules of definite integral and double integral.

The first integral is a bit tricky, as the limits of integration are not in the standard order (with respect to x and y). However, we can change the order of integration by switching the limits of integration, so that we can use Fubini's theorem.

The double integral can be solved by converting the rectangular region R into polar coordinates.

The double integral is ∫∫R 5xsin(x+y)dA, R=[0,pi/3]×[0,pi/6]. This can be further solved as

= ∫(0,pi/3) ∫(0,pi/6) 5rrsin(rcos(θ)+rsin(θ))dθ dr

= ∫(0,pi/3) ∫(0,pi/6) 5r^2sin(r(cos(θ)+sin(θ)))dθ dr

= ∫(0,pi/3) 5r^2(-cos(r*(cos(θ)+sin(θ))) | (0,pi/6))dr

= ∫(0,pi/3) 5r^2(-cos(r*(√(2)/2)))dr

= -5/2∫(0,pi/3) r^2cos(r*(√(2)/2))dr

The integral above is not in a closed form but can be evaluated using numerical integration techniques.

The new point that will be formed when the point (-4,5) is rotated 270 degrees counterclockwise is; (5, 4)

There are different types of transformations namely dilation, rotation, reflection e.t.c

Now, when we rotate a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means that we switch x and y and make x negative.

Now, we are told that the point (-4,5) is rotated 270 degrees counterclockwise. Thus, following the transformation rule as described above gives us;

(-4,5) → (5, 4)

Thus, we conclude that the new coordinate we will obtain in this process is (5, 4)

The formula for the area of a trapezoid is (a+b)*h/2, where a and b are the lengths of the bases and h is the height.

To estimate the total area between the curve and the x-axis using trapezoids, we can divide the region between the curve and the x-axis into a number of trapezoids, and calculate the area of each trapezoid. The sum of the areas of all the trapezoids will estimate the total area.

For example, consider the curve y = x^2 and the x-axis between x = 1 and x = 2. We can divide this region into 3 trapezoids with bases at x = 1, x = 1.5, x = 2, and heights of 0.25, 0.5625, and 1 respectively.

The area of the first trapezoid is (1 + 1.5) * 0.25 / 2 = 0.1875

The area of the second trapezoid is (1.5 + 2) * 0.5625 / 2 = 0.40625

The area of the third trapezoid is (2 + 2) * 1 / 2 = 1

The sum of the areas of all the trapezoids is 0.1875 + 0.40625 + 1 = 1.60625. This estimates the total area between the curve y = x^2 and the x-axis between x = 1 and x = 2.

The angle B in triangle ABC is 60° i.e. C.

What is a triangle?

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

Based on the sides of a triangle, a triangle is classified into 3 types, namely:

Scalene Triangle – All the sides are of different measures.

Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.

Equilateral Triangle – All the 3 sides of a triangle are of the same measure.

Based on the angles of a triangle, a triangle is classified into 3 types, namely:

Acute Angle Triangle – All the angles of a triangle is less than 90°.

Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.

Right Angle Triangle – One of the angles of a triangle is equal to 90°.

Now

∠NAB+∠CAB=180°  (Supplementary angles)

∠CAB=180-∠NAB

=180-100

∠CAB=80°

Answer: 4/7

Step-by-step explanation:

pretty simple, 1/7 and 3/7 both has a denominator of "7", so the seven stays the same. (While writing this I made a chart to see where I put everything)

Write:

 1/7 = (denominator 7)

+ 3/7 = (denominator 7)

Now we start doing the math, what goes into 7? 7x1 so 1 x 3 = 3

know we go up to the numerator, 7x1=7, so 1 x 1 = 1

add 3 + 1 and that adds up to 4

so your answer is 4/7, hope it helps

Answer: Roger should pick Printer B because it prints 2 more pages per minute.

Step-by-step explanation: We are given that printer A prints 33 pages per minute. We have to figure out how many pages printer B prints in a minute.

As shown in the table, in 2 minutes, printer B prints 70 pages, and in 3 minutes it prints 105 pages. We can create a function to model the rate at which printer A prints pages. This is a linear function since for each increase in x, there is a proportional increase in y. This means that if we were to back one minute the printer would print 35 pages since the common difference per minute is 35 pages. The function would therefore be p=35m where m=minutes and p=pages. This means that printer B produces 2 more pages than printer A per minute since 33+2=35.

The equation of the line in slope intercept form is y = 1 / 2 x - 3 / 2.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Let's find the slope of the line using the coordinates.

Therefore, using (-1, -2) and (-5, -4)

Hence, the slope of a line is the change in the dependent variable with respect to the change in the independent variable.

Therefore,

m = -4 + 2 / -5 + 1

m = - 2 / -4

m = 1 / 2

Therefore, let's find the y-intercept using (-1, -2)

y = 1 / 2 x + b

-2 = 1 / 2 (-1) + b

-2 + 1 / 2 = b

- 3 / 2 = b

Therefore, the equation of the line is y = 1 / 2 x - 3 / 2.
