To solve for y, all you have to do is just separate r from all of the others and make it equal to the rest of the equation. So first it was, a=pi*r squared.
Divide by pi on each side,
a/pi=r^2
Take the square root of each side;
square root of (a/pi) =r
and that's all
Hope this helps.
Step-by-step explanation:
40/25*100 = 40*4 = 160%
Answer:
The second graph is the answer
Step-by-step explanation:
The questions asks for the domain of [f/g](x).
That is f(x) / g(x) = [x^2 - 25] / [X-5].
The domain of that functions are all the real except those where the denominator becomes zero.
You find those points by doing X - 5 = 0 => x = 5.
Then, the domain of [f/g](x) is all real numbers except x = 5.

Suppose, we have to find average rate of change of f(x) on [a,b]
we can use average rate of change formula
on [-2,3]
we can look at the table
g(3)=12.5
g(-2)=400
so, we can plug these values
