Answer:
A = 50.26 sq meters
Step-by-step explanation:
we have to find the diameter first by using the circumference:
C = πd
25.12 = πd
25.12/π = d
8 = d
this means the radius is 4
A = πr²
A = π4² or 16π
A = 50.26 sq meters
- h(x) = f(x) + g(x) =
- h(x) = g(x) – f(x) =
- h(x) = 4g(x) =
<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or 
.

Answer:
A
outdoor temperature as a function of time
Step-by-step explanation:
If you put the temperture as a function of time, every passing hour or minute the tempurture decreases resulting in a decrease in your function.
This can also be shown in a graph were the tempuerture is the x and the time is the y. Each hour that passes the temputure goes down until night falls and the temputure reaches a constant rate of tempurture
