Answer:

See explanation

Step-by-step explanation:

Assuming the cylinder has a radius of the cylinder is 3 inches, then r=3

Given that the lateral surface area of the cylinder is 60, then we can use the formula:

L.S.A = 2\pi \: rh

We substitute the values to get;

60 = 2 \times 3.14 \times 3h

We solve for h to get:

h =  \frac{60}{2 \times 3.14 \times 3}  =  \frac{10}{3.14}  = 3.1847

In this case the correct answer is 3.18 inches.

Let a and b be real numbers satisfying a^3 - 3ab^2 = 47 and b^3 - 3a^2 b = 52. Find a^2 + b^2.
boyakko [2]

Answer: a²+b² = -99/2

Step-by-step explanation:

Since we are given two equations, this equations will be solved simultaneously to get a² and b²

a³ - 3ab² = 47 ... 1

b³ - 3a² b = 52... 2

From 1, a(a² - 3b²) = 47...3

From 2, b(b² - 3a²) = 52... 4

Adding 3 and 4, we have;

a²+b²-3b²-3a² = 99 (note that a and b will no longer be part of the equations as they have been factored out)

a²+b²-(3b²+3a²) = 99

(a²+b²) -3(b²+a²)= 99

Taking the difference we have

- 2(a²+b²) = 99

a²+b² = -99/2

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−4, 2)
Romashka [77]

See the graph

<h2>Explanation:</h2>

Remember to write complete questions in order to get good and exact answers. Here you haven't provided any option, but it's easy to plot this point on a coordinate system in order to know the location of the movie theater. We know that this theater is at the point:

(-4,2)

So let's plot this point in the cartesian plane:

  • The x-coordinate is -4
  • The y-coordinate is 2.

So the graph is shown below. Remember that the horizontal axis is called the x-axis while the vertical axis is called the y-axis.

  • x > 0 for the x-values to the right of the origin.
  • x < 0 for the x-values to the left of the origin.
  • y > 0 for the y-values above the origin
  • y < 0 for the y-values below the origin.
