Answer:
-12
Step-by-step explanation:
Let b = -1 and a = -3
The average rate of change =
f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2
f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22
f(b) - f(a) = -2 - 22 = -24
b - a = -1 + 3 = 2
= -24/2 = -12

The complete question in the attached figure
we know that
(35)/(40.5+54)=x/54-------- > (35)/(94.5)=x/54---------> x=(54)*(35)/(94.5)
X=20 ft
the answer is 20 ft
we know that

X=20 ft
the answer is 20 ft
Answer:
The height of the platform is 20 ft
Step-by-step explanation:
In the figure attached, the problem is shown.
Let's call α to the angle opposite to the 35 ft side. From sine definition:
sin α = opposite/hypotenuse
Taking into consideration both, major and minor triangles:
sin α = 35/(40.5 + 54) = x/54
where x can be isolated, as follows:
x = 35/(40.5 + 54) * 54 = 20 ft
