Answer:
558.01 ft
Step-by-step explanation:
To obtain the height of cell tower :
Height of post / shadow of post = height of tower / shadow of tower
Shadow of post = 16 in = 1.333333 ft
6/ 1.3333 = height of tower / 124
6 * 124 = 1. 3333 * height of tower
744 = 1.3333 * height of tower
Height of tower = 744 / 1.3333
Height of tower = 558.01
Height of tower = 558.01 ft
The answer should be B: 33.0
I just used a calculator.
x^2 + y^2 - 4y - 15 = 6
x^2 + y^2 - 4y = 21
x^2 + y^2 - 4y + 4 = 25
x^2 + (y - 2)^2 = 5^2
r = 5
