Problem page a manufacturer makes decorative globes out of silver in the shape of a solid sphere. suppose each sphere has a radius of 1.5 cm. if silver is priced at $6.00 per cm3 , how much will the silver cost to make one solid sphere? use 3.14 for pi, and do not round your answer.

Step-by-step explanation:

step 1

Find the volume of the sphere

The volume of the sphere is equal to

we have

substitute

step 2

Find the cost

Multiply the volume by $6.00 per cm^3

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
