The answer is B. 58
Using the equation to get 29. Then multiply by 2 to get 58.
The equation of the circle shown is:
![x^2 + y^2 = 100](https://tex.z-dn.net/?f=x%5E2%20%2B%20y%5E2%20%3D%20100)
<h3>What is the equation of a circle?</h3>
The equation of a circle of center
and radius r is given by:
![(x - x_0)^2 + (y - y_0)^2 = r^2](https://tex.z-dn.net/?f=%28x%20-%20x_0%29%5E2%20%2B%20%28y%20-%20y_0%29%5E2%20%3D%20r%5E2)
From the graph, it can be seen that the center of the circle is (0,0), thus
and the radius is of r = 10, hence the equation is:
![x^2 + y^2 = 100](https://tex.z-dn.net/?f=x%5E2%20%2B%20y%5E2%20%3D%20100)

Because we're treating the swimming pool as a standard rectangle, rather than a three dimensional shape, we can use the formula L * W = A to calculate the length of the pool.
Length * Width = Area
We've established two key bits of information, and with them we can solve for the final piece.
Length * 4 = 16
4l = 16
Divide both sides by 4.
l = 4
<h3>The length of the pool is 4 meters.</h3>
Answer:
Inverse Function: f^-1(x) = 9/4x + 9
Step-by-step explanation:
To find the inverse function we can interchange the position of the variables x and y, and then solve for y;
y = 4/9x - 4 => x = 4/9y - 4,
x = 4/9y - 4,
4/9y = x + 4,
y = 9/4x + 9/4(4),
y = 9/4x + 9/ f^-1(x) = 9/4x + 9
Answer:
270
Step-by-step explanation:
becasue 100 percent of 90 would be 90
![100*3=300](https://tex.z-dn.net/?f=100%2A3%3D300)
so multiply
![90*3=270](https://tex.z-dn.net/?f=90%2A3%3D270)
