Answer:
C
Step-by-step explanation:
C is the only function that have a consistent decrease while A is a trigonometric function, B is a non linear function, D is an exponential function
The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!

A non-negative root of a number is called Square Root
Answer:
C. 254.34 in^2
Step-by-step explanation:
The formula for area of a circle is πr² (pi x radius x radius).
Here, only the diameter is shown.
To find the radius, divide the diameter by 2.
18 / 2 = 9
9 is the radius.
We use 3.14 as π (pi).
Now we have the final equation.
pi x radius x radius
3.14 x 9 x 9 = 254.34 in^2.
Therefore, the area of the circle is 254.34 in^2.
