Answer:
60 ft
Step-by-step explanation:
This can be solved by setting up a proportion.
height of the pole/length of the pole's shadow = height of the mailbox/length of the mailbox's shadow
height of the pole = x
plugging in values
x/70 = 3/3.5 To solve, cross multiply
(3.5)(x) = (70)(3) Simplify
3.5x = 210 Divide both sides by 3.5
3.5x/3.5 = 210/3.5
x = 60 ft is the height of the pole
We have the following function:
y = 2x ^ 2 - 12x - 32
We match zero:
2x ^ 2 - 12x - 32 = 0
We rewrite the function:
x ^ 2 - 6x - 16 = 0
(x-8) * (x + 2) = 0
The zeros of the function are:
x1 = 8
x2 = -2
Where,
8> -2
Thus,
d = 8
e = -2
Then, to find the minimum function we derive:
y '= 4x - 12
We equal zero and clear x:
4x-12 = 0
x = 12/4
x = 3
Therefore, the value of f is:
f = 3
Answer:
The values of d, e, and f are:
d = 8
e = -2
f = 3
