answer
f(-5)=115
Step-by-step explanation:
x+5=0
x=-5
f(x)=3x^2-7x+5
f(-5)=3*(-5)^2-7(-5)+5
f(-5)=3*25+35+5
f(-5)=115
Answer:
The second answer.
Step-by-step explanation:
Tim is correct. Absolute value is just the distance away from 0. In this case, both P and Q are 3/8 away from zero, even though they have opposite signs. In fact, opposites signs of the same number will always have the same absolute value because they are the same distance from 0.
So, it is the second one.

Answer:
I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.
Step-by-step explanation:
Once we are considering
, the range of
is
. Therefore,
is not true.
In this exercise, we may have

Considering the trigonometric functions beyond the unit circle.
Or considering the definition in the right triangle:

I believe this would be 12.45
