Answer:
A. Building A, it is around 100.69 feet taller than building B.
Step-by-step explanation:
Since building A is 120 feet away at and elevation of
, then:
Tan
= 
Where x is the height of the building at the horizontal plane.
x = Tan
× 120
= 100.692 feet
For building B at the same elevation,
Tan
= 
x = Tan
× 60
= 50.346 feet
Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
Answer:
slope = - 
Step-by-step explanation:
the slope of the secant line in the closed interval [a, b ] is
slope = 
here [a, b ] = [1, 4 ]
f(b) = f(4) = -
+ 5 = - 16 + 5 = - 11
f(a) = f(1) = -
+ 5 = - 2 + 5 = 3
slope =
=
= - 
I think the answer is 32.
