A stain glass window is shaped like a semicircle. The bottom edge of the window is 36 inches long. What is the area of the stain
Lubov Fominskaja [6]
I don't really have a calculator on me. But I'll tell you how to go through it.
So the formula for the area of a circle is Pi x radius^2.
So since the diameter is 36, divide that by 2 to get the radius, and you're left with 18. Now do 18 squared and then times that by Pi. Now you've got the area of the whole circle, but since we only have a semicircle, you need to divide your answer by two to get the area of the semi circle

Consider the function f(x) = √5x + 15 for the domain [-3, ∞).Find f-¹(x), where f-1 is the inverse of f.Also state the domain of
Ymorist [56]

Answer: We have to find the inverse function of the following:

f(x)=\sqrt{5x+15}\rightarrow[-3,\infty)\Rightarrow(1)

The Inverse of the (1) is as follows:

\begin{gathered} f(x)=y=\sqrt{5x+15} \\  \\ \text{ Switch: }x\text{  and }y\text{ and solve for }y(x)\text{ } \\  \\  \\ y=\sqrt{5x+15}\rightarrow x=\sqrt{5y+15} \\  \\  \\ x^2=5y+15 \\  \\  \\ x^2-15=5y \\  \\  \\ y=\frac{x^2}{5}-\frac{15}{5} \\  \\  \\  \\ y=f^{-1}(x)=\frac{x^2}{5}-3 \\  \\  \\ f^{-1}(x)=\frac{x^{2}}{5}-3 \end{gathered}

The domain of the inverse function is:

x\in(-\infty,+\infty)

$1.25p = a

I believe that is how you would formulate it.

1.25 multiplied by the amount of pounds purchased (p) equals (=) the total cost of apples (a)
