F(x) = 8x-x^2 only if x is equal to 8 or less than 8
OR
f(x) = x^2+3 only if x > 8
We can only pick one of the two paths. The function f(x) can't be both at the same time. In the case of computing f(8) we have the input x = 8. It won't fit the bottom piece as x > 8 is false when x = 8. The inequality 8 > 8 is false
So instead we pick the top piece
x = 8 ----> so "x is less than or equal to 8" is true
f(x) = 8x - x^2
f(8) = 8*8 - 8^2
f(8) = 64 - 64
f(8) = 0
The final answer is 0
Answer:
SAS
Step-by-step explanation:
You are already given that two sides are congruent, thus making the "s" part. You can further say that two angles are congruent, due to the verticle angle theorem!
The height of the tank is 12 inches
Answer:
There are 8 roots
1,2,5,10,-1,-2,-5,-10
Step-by-step explanation:
The rational root theorem says take all the factors of p over all the factors of q
p = 1,2,5,10
q = 1
roots ± 1,2,5,10

roots ±1, ±2, ±5,±10
the line-of-sight distance from the television camera to the base of the stadium is 1449.28 m .
<u>Step-by-step explanation:</u>
A blimp provides aerial television views of a baseball game. The television camera sights the stadium at a 12° angle of depression. The altitude of the blimp is 300 m. We need to find What is the line-of-sight distance from the television camera to the base of the stadium . Let's find out:
According to question , given scenario is in a right angle triangle where
, where x is angle of depression.
We know that
⇒
⇒
⇒
⇒
Therefore , the line-of-sight distance from the television camera to the base of the stadium is 1449.28 m .
