Answer:
they are neither
Step-by-step explanation:
if they were parallel, they would have the same slope.
if they were perpendicular, they would have one positive slope of a value and the negative version for the other slope (example: one slope would be -8 and the other would be 8)
To decrease an amount, you would multiply it by 0.30. you multiply it by 0.30 because this gives you 30%; therefore, it has been decreased by 70%. To decrease an amount, you always times it by 0. and then whatever the remainder is. If you were decreasing 'y' by 65%, you would work it out by doing y * 0.35
Answer:
y = 1.8

Answer:
6 m/s
Step-by-step explanation:
The formula for kinetic energy is ...
KE = (1/2)mv² . . . . m is mass
Filling in the given values, we can solve for v.
1440 J = (1/2)(70+10 kg)v^2
(1440 J)/(40 kg) = v^2 = 36 m²/s² . . . . m is meters
v = √(36) m/s = 6 m/s
The man is moving at 6 meters per second.
_____
In terms of units analysis, the joule (J) is a derived unit equal to ...
1 J = 1 kg·m²/s²
Answer:
$23.45
Step-by-step explanation:
5.79 x 2.25 = 13.03
5.79 x 1.8 = 10.42
total = 23.45
