Answer:

Step-by-step explanation:
![(f-g)(x) = f(x) - g(x) = [4x^2 + 5x -3] - [4x^3 - 3x^2 + 5]](https://tex.z-dn.net/?f=%28f-g%29%28x%29%20%3D%20f%28x%29%20-%20g%28x%29%20%3D%20%5B4x%5E2%20%2B%205x%20-3%5D%20-%20%5B4x%5E3%20-%203x%5E2%20%2B%205%5D)

To solve this, use proportions. The height of the pole corresponds to the height of the building; the shadows are corresponding: 3.1/x =1/45.5
3.1 times 45.5=1x
141.05=x
The building is 141 meters tall
Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
