The equation of a circle with center
and radius
is
![(x-x_0)^2+(y-y_0)^2=r^2](https://tex.z-dn.net/?f=%28x-x_0%29%5E2%2B%28y-y_0%29%5E2%3Dr%5E2)
In your case,
![x_0=3,\quad y_0=-2,\quad r=3](https://tex.z-dn.net/?f=x_0%3D3%2C%5Cquad%20y_0%3D-2%2C%5Cquad%20r%3D3)
Plug these values into the generic formula and you'll get your equation.
Answer:
Domain: All real numbers or (-∞, ∞)
Range: [-9, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted by the domain.
We can see that you can plug in any x-value into the graph. Therefore, any number would work (All real numbers).
We can also see that are absolute minimum y-value is -9. Therefore, our range is from -9 (included) to infinity.
Answer:
6 ![ft.^{2}](https://tex.z-dn.net/?f=ft.%5E%7B2%7D)
Step-by-step explanation:
Use the triangle area equation
![A=\frac{b*h}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bb%2Ah%7D%7B2%7D)
plug in the base (4ft) times the height (3ft) then divide by two
