An engineer designed a suspension bridge with three hanging cables, with the end of each cable attached to a tower. He defined cable AB by the function f(x) = 0.1(x+11)^2+5 The bridge has a clearance of 24ft above the water's surface. Knowing that the width of each tower is 2 ft, what is the height of each tower?
(Assume that the tower at point B is centered on the y-axis and that the cables are attached to the ends of the tower.)

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
