D. is the answer to your question
Answer:
So -8*<4 Is not a complete Problem... If your saying -8<4 then the anwser is 1. But im guessing your saying -8X<4 which is negative eight ex (x) less than four. so heres that:
Step-by-step explanation:
Let's solve your inequality step-by-step.
−8x<4
Step 1: Divide both sides by -8.
−8x/−8<4/−8
=x>−1/2

Answer:
Option 3
Step-by-step explanation:
Multiplying the x^2 always causes the opening on the parabola to get thinner. If you multiply it by a number less than 1 it will make it wider.
Answer:
2 Units
Step-by-step explanation:
THere may be easier ways to do it, but I would just convert them to rectangular and find the distance between those.
(3, -60) becomes (3cos(-60), 3sin(-60)) = (3/2, -3*sqrt(3)/2)
(-5, 105) becomes (-5cos(105), -5sin(105)) = (5/2, -5sqrt(3)/2)
Now just use the distance formula, or in other words think of the two points as being connected by a horizontal and vertical line to form a right triangle. The idea is to find the hypotenuse of that right triangle.
sqrt((3/2 - 5/2)^2 + (-3sqrt(3)/2 + 5sqrt(3)/2)^2)
sqrt((-2/2)^2 + (2*sqrt(3)/2)^2)
sqrt(1 + 3)
sqrt(4)

We know that:
Epg=mgh
Epg=25kg*9,81m/s²*3m
Epg=735,75J
