Which sphere has a volume of 0.288Pi in.3? A sphere with radius 0.4 inches. A sphere with radius 0.5 inches. A sphere with radiu
worty [1.4K]

<em>C. A sphere with radius 0.6 inches.</em>

<u><em>Here is why:</em></u>

The equation for the volume of a sphere is:

V=\frac{4}{3} \pi r^3

We can plug in and solve.

V=\frac{4}{3}*\pi *0.6*0.6*0.6

We will multiply everything but leave the 3 to divide later.

So...

4*\pi *0.6*0.6*0.6=0.864\pi

Divide by 3.

0.864\pi /3=

0.288π

8. Graph the following equation: y = x2 + 4x - 5
Dennis_Churaev [7]

Answer:

Given: y = x2 + 4x – 5

Find the following

y-intercept

x-intercepts or the zeros of the functions or roots

graph of the function, given vertex is at (-2, -9)

Solve the system of linear equations      – x + 6y = 8        2x + 5y = 3

Write the names of curves, given their equations:  

x2/16 + y2/9 = 1

3y = 2x + 5

(x - 5)2 + (y + 6)2 = 25

x2/16 – y2/25 = 1

y = 2x2 + 10x + 25

Write down the first five terms of the arithmetic progression with the first term 8 and common difference 7, then find the 17th

Write down the first five terms of the geometric progression with the first term 3 and common ratio 2, then find the 17th
