Find the volume of a cone with a base area 36pi and a height equal to twice the radius

The volume of a cone is V= \frac{1}{3} A_{\text{basis}}\cdot H. Since A_{\text{basis}}=36\pi and you know that basis is a circle you can conclude that \pi R^2=36\pi and R=6.

If <span>height H equal to twice the radius R, then H=2R=2\cdot 6=12.</span>

The volume will be:V= \frac{1}{3} \cdot 36\pi \12=144\pi cubic units.

2.8 = 2y<br> What does y equal?<br> 1.4<br> 0.5<br> 2.8<br> 0.6
igor_vitrenko [27]

Answer: 1.4

Step-by-step explanation: First, swap the sides of the equation so that the one with the variable can be in front.

So, its 2y=2.8

To solve this, you simply divide both sides of the equation by 2.

2 divided by 2 is 0. That leaves you with the y by itself. Then, 2.8 divided by 2 is 1.4

So, y=1.4

What is the inverse of the function f(x) = 2x – 10?
Nadusha1986 [10]

Answer:

f⁻¹(x) = (1/2)x +5

Step-by-step explanation:

In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).

... y = 2x -10

... x = 2y -10 . . . . . . swapped variables

... x +10 = 2y . . . . . add 10

... (1/2)x + 5 = y . . . . divide by 2

... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
