Answer:
Area = 5(x + 4y - 6).
Step-by-step explanation:
The area of the whole figure = area of rectangle + area of the triangle
= 10(2y - 3) + 1/2 * 10 * x
= 20y - 30 + 5x
= 5(x + 4y - 6).
Answer:
f(6) = - 4
Step-by-step explanation:
Substitute x = 6 into f(x) , that is
f(6) = - 6 + 2 = - 4
Answer:
-25

Given a radius
, the volume of a sphere is given by

We can solve this formula for the radius, given the volume:
![r=\sqrt[3]{\dfrac{3V}{4\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B3V%7D%7B4%5Cpi%7D%7D)
We can plug our value for the volume to get the radius:
![r=\sqrt[3]{\dfrac{3\cdot 12\pi}{4\pi}}=\sqrt[3]{9}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B3%5Ccdot%2012%5Cpi%7D%7B4%5Cpi%7D%7D%3D%5Csqrt%5B3%5D%7B9%7D)
