There are 10 golf balls in a rectangular prism. Each golf ball has a diameter of 1.25 inches. Find the volume of the golf balls
lara31 [8.8K]
The answer is D.

The formula for the volume of a sphere is \frac{4}{3}  \pi  r^{3} 

You would divide the diameter in half which would give you your radius (r).
Then you plug in the radius value to find the volume of ONE ball.
You would then multiply by 10 to find the volume of TEN golf balls.

D is the closest answer to the volume of ten golf balls

The path of an underwater drone is modeled by quadratic function d, where x is the horizontal distance, in miles, from the launc
soldier1979 [14.2K]

Based on the vertex form equation, the statements that are true are:

A.) the drone reaches its minimum 25 miles from the launch site

C.) at its minimum, the drone’s depth is -180 meters.

<h3>Rewriting the equation in vertex form</h3>

Given:

x = horizontal distance, in miles, from the launch site

d(x)= depth below the surface of the water, in meters.

Equation= 0.4x ²- 20x + 70

Hence

Rewritten the given equation ( 0.4x ²- 20x + 70) in vertex form will be:

Vertex form: d(x)=[2(x-25)²÷5] -180

Vertex= -180, 25

Minimum=-180 at x=25

Therefore the correct option is A, C.

Find an equation for the plane containing the point (1, 2, 3) and parallel to the plane x 2y 3z
sergeinik [125]

Answer:

Step-by-step explanation:

Heres the full question and solution:

Find an equation for the plane containing the point (1,2,3) and parallel to the plane x+2y+3z=5.

solution

Any plane parallel to x+2y+3z=5 is  x+2y+3z=d&#10;

since the plane is passing through (1,2,3)

we substitute point in equation

1+2\times 2+3\times 3=d\\d=14&#10;\\x+2y+3z=14

equation of the line is x+2y+3z=14
