Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>

Answer:
-9
Step-by-step explanation:
The applicable exponent rule is ...
a^b·a^c = a^(b+c)
___
For the y factor, ...
y^-13 · y^4 = y^(-13+4) = y^-9 . . . . . exponent of -9
Answer:
Correct option: Third one
Step-by-step explanation:
Let's analyse each sentence:
"Both x = -8 and x = 8 are roots of f(x)"
False, we can't affirm that x = 8 is a root of f(x) with the information given.
"Neither x = -8 nor x = 8 is a root of f(x)"
False, because x = -8 is a root of f(x), because the factor (x + 8) would be zero, and it is multiplying the rest of the function, so the final value would be zero.
"f(-8) = 0"
True, because x = -8 is a root, and the factor x + 8 will be zero and will multiply the other factors of f(x)
"f(8) = 0"
False, because x = 8 is not a root of f(x)
So the correct option is the third one
