what is the upper sum for f(x)=17−x2 on [3,4] using four subintervals?

Answers

Answer 1

the upper sum for f(x) = 17 - [tex]x^{2}[/tex] on the interval [3, 4] using four subintervals is approximately 6.46875.

To calculate the upper sum, we divide the interval [3, 4] into four subintervals of equal width. The width of each subinterval is (4 - 3) / 4 = 1/4.

Next, we evaluate the function at the right endpoint of each subinterval and multiply it by the width of the subinterval. For this function, we need to find the maximum value within each subinterval. Since the function f(x) = 17 - [tex]x^{2}[/tex] is a downward-opening parabola, the maximum value within each subinterval occurs at the left endpoint.

Using four subintervals, the right endpoints are: 3 + (1/4), 3 + (2/4), 3 + (3/4), and 3 + (4/4), which are 3.25, 3.5, 3.75, and 4 respectively.

Evaluating the function at these right endpoints, we get: f(3.25) = 8.5625, f(3.5) = 10.75, f(3.75) = 13.5625, and f(4) = 13.

Finally, we calculate the upper sum by summing the products of each function value and the subinterval width: (1/4) × (8.5625 + 10.75 + 13.5625 + 13) = 6.46875.

The additive inverse of (-3 9) is (3 -9). This means that if you add the two numbers together, the result is zero.

(-3 9) + (3 -9) = 0

The additive inverse of a number is a number that when added to the original number produces a result of zero. In other words, the two numbers have the same absolute value, but one is the opposite sign of the other.

For example, the additive inverse of (-3 9) is (3 -9). This means that if you add the two numbers together, the result is zero. To demonstrate this mathematically, (-3 9) + (3 -9) = 0.

The concept of additive inverse is important in mathematics because it is used to solve equations. By understanding the concept, you can quickly find the solution to an equation by adding the opposite of the number in question.

Furthermore, additive inverse is also important in understanding the concept of subtraction. Subtraction can be thought of as addition of the inverse of the number being subtracted. For example, if you subtract 3 from 9, you can also think of it as adding the inverse of 3 to 9, which would be (-3). Therefore, 9 - 3 = 9 + (-3) = 6.

Answers

The volume of the solid is 207.23 cm³.

Volume of the Solid:

Volume is the area occupied by an object/matter (solid, liquid, gas) within a 3D object. Alternatively, the volume of a three-dimensional object is generally defined as the capacity of the object that matter can hold.

For example, the volume of a cubic box indicates how much water or other substance it can contain. For ice cream cups, the amount of ice cream that can fit in the cup without gaps corresponds to the volume of the ice cream cup.

Now, based on the question:

Volume of Solid = Volume of Cylinder + Volume of Cone

Volume of Cylinder = πr²h

v= 3.14 * (3)² * 6

v = 169.56

Volume Of Cone:

Cone volume defines the space or volume of the cone. A cone is a three-dimensional geometric shape with a circular base that tapers from a flat base to a point called an apex or vertex. A cone is formed by a series of line segments, half-lines, or lines connecting vertices that are common to all points on the base in a plane that does not contain vertices. A cone can be thought of as a series of noncongruent disks that overlap each other such that the ratios of the radii of adjacent disks are kept constant.

We know that :

Volume of Cone = πr² h/3

v = 3.14 * (3)² * 4/3

v = 37.7

Now,

Volume of Solid = 169.56 + 37.7

An office building has two elevators. One elevator starts out on the 4th floor, 35 feet above the ground, and is descending at a rate of 2.2 feet per second. The other elevator starts out at ground level and rising at a rate of 1.7 feet per second



Answers

The system of equations is y = 35 - 2.2x and y = 1.7x.

The solution of the system of equations is (8.97,15.25).

At about 8.97 seconds, both elevators will be about 15.25 feet above the ground.

What is an elevator?

An elevator, often known as a lift, is a car that moves vertically in a shaft to transport passengers or freight between the levels of a multistory building. Most modern elevators are propelled by electric motors via a system of wires and sheave with the assistance of a counterweight (pulleys).

Given that there are two elevators in an office. The 4th floor of the office at 35 feet above the ground and is descending at a rate of 2.2 feet per second.

The equation represents the height of the elevator above the ground after x seconds is y = 35 + (-2.2)x. Since the elevator is descending at a rate of 2.2 feet per second.

The other elevator starts out at ground level and rises at a rate of 1.7 feet per second.

The equation represents the height of the elevator above the ground after x seconds is y = 1.7x. Since the elevator is rising at a rate of 1.7 feet per second.

The system of equations is

y = 35 + (-2.2)x .....(i)

y = 1.7x   ........(ii)

Solve the equations substitution method.

Putting y = 1.7x in equation (i)

1.7x = 35 + (-2.2)x

1.7x = 35 - 2.2x

Add 2.2x on both sides:

1.7x + 2.2x = 35

3.9x = 35

Divide both sides by 3.9:

x = 35/3.9

x = 8.97

Putting x = 8.97 in equation (ii)

y = 1.7 × 8.97

y = 15.25

After 8.97 seconds, the elevators will be 15.25 feet above the ground.

The measure of the missing angle is 21°.

How to find a interior and exterior angle of triangle? Interior angles of a triangle are the angles inside the triangle that are formed by the intersection of two sides. To calculate the measure of an interior angle, you can use the formula: interior angle = 180-(angle 1 + angle 2). This formula works for all triangles, regardless of the size or shape. Exterior angles of a triangle are the angles outside the triangle that are formed by extending one of the sides. To calculate the measure of an exterior angle, you can use the formula: exterior angle = angle 1 + angle 2. This formula works for all triangles as well. To find the interior and exterior angles of a triangle, you need to know the measures of the angles of the triangle. If you don’t know the measures of the angles, you can use the following steps:

1. Measure the length of each side of the triangle.

2. Using the triangle inequality theorem, determine the angles of the triangle.

3. Use the formula to calculate the measure of each interior and exterior angle.

By following these steps, you can easily calculate the interior and exterior angles of a triangle.

Solution:

To measure a missing angle of triangle,

∠ABC + ∠ACB + ∠CAB = 180°

x + 132° + 27° = 180°

• The price per pound that the grocery store is willing to pay is decreasing with more lobsters: $3.85 - 50.0005 * y, where y is the total lobster amount sold in pounds.

• The amount of lobster that Amir catches in a single day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.

Amir decides to sell a fixed percentage of lobster to the local restaurant and the rest to local grocery stores. Using either math or simulation, can you help Amir determine what percentage he should choose in order to maximize his expected profit in the long run?
Previous question

Answers

The expected profit in the long run can be determined by calculating the expected value of the total revenue from selling the lobsters. The expected total revenue is the sum of the expected revenue from selling the lobsters to the restaurant and the from selling the lobsters to the grocery store.

The expected value of the revenue from selling the lobsters to the restaurant can be calculated by multiplying the expected price per pound from the restaurant by the expected amount of lobsters caught in a day. The expected price per pound from the restaurant follows a triangular distribution with minimum value $1.50, maximum value $5.50, and likeliest value $3.50. The expected amount of lobsters caught in a day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.

The expected value of the revenue from selling the lobsters to the grocery store can be calculated by multiplying the expected price per pound from the grocery store by the expected amount of lobsters caught in a day. The expected price per pound from the grocery store is decreasing with more lobsters: $3.85 - 50.0005 * y, where y is the total lobster amount sold in pounds. The expected amount of lobsters caught in a day follows a normal distribution with mean 1,500 pounds and standard deviation sqrt(12,500) pounds.

Given the expected values of the total revenue from selling the lobsters to the restaurant and the grocery store, Amir can use simulation to determine the optimal percentage of lobsters to sell to the restaurant in order to maximize his expected profit in the long run. He can run several simulations with different percentages of lobsters to be sold to the restaurant and compare the expected profits for each simulation. The percentage that produces the highest expected profit is the optimal percentage for Amir to maximize his expected profit in the long run.

Amir can use simulation to determine the optimal percentage of lobsters to sell to the restaurant in order to maximize his expected profit in the long run. He can calculate the expected value of the total revenue from selling the lobsters to the restaurant and the grocery store, and then run several simulations with different percentages of lobsters to be sold to the restaurant to compare the expected profits for each simulation.

How do you dilate a triangle with a scale factor of 3?

Answers

Dilation is a transformation that changes the size of an object while keeping its shape the same.

In this case, the scale factor of 3 tells us that the triangle will be three times larger than the original triangle.

To perform the dilation, you would take each vertex of the triangle and multiply the x-coordinate and y-coordinate by 3. For example, if one vertex of the original triangle had coordinates (x, y), the coordinates of that same vertex in the dilated triangle would be (3x, 3y).

It's also worth noting that the dilation is done with respect to a fixed point called the center of dilation. You can think of this point as the "pivot" around which the dilation occurs.

The center of dilation is typically represented by the letter "O".

As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.

Divide the difference in elevation between two points by the distance between them, multiply the result by 100, and that is the percent slope. The term "rise" refers to the elevational difference between two places. The run is the distance separating the points. The formula for percent slope is (rise / run) x 100.

Answer: [tex]\frac{(\sqrt{10} +3)^{2}+1 }{\sqrt{10}+3 }[/tex]

Step-by-step explanation:

1) 5x + 2y = -4
2) -x + 2y = 8
these need to be in slope intercept form​

Answers

Answer:

1) y=5/2x +2

2) y=1/2x+4

Step-by-step explanation: Slope intercepts equation is y=mx+b. After solving your slopes for each problem would be 5/2x and 1/2x, then you would solve to find B, which for this problem is 2, and 4. You would leave the y as just a regular y for this problem.
