Answer:
The potential energy of the ball having 2kg mass would be
J
Step-by-step explanation:
I am assuming the ball has a mass of 2 kg, as you have not mentioned the mass of a ball.
Considering the formula for calculating the gravitational potential energy

As
kg
Acceleration of gravity = g = 9.8 
As the ball is on the height = h = 20 meters
So,

J
Therefore, the potential energy of the ball =
J

First, find the slope of the initial line;
m=(y₁-y₂)/(x₁-x₂)
m=(4-0)/(11-8)
m=4/3
If two lines are parallel, the slope is the same although the intercept can differ.
If this parallel lines passes through the point (4, 5);
y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c
(15/3)=16/3+c
(15/3)-(16/3)=c
-1/3=c
Therefore, the final equation should be y=4/3x-1/3

X3/4 is the answer for this question
Six books at 8 dollars each is equivalent to $48.00
You are only paying 80% of that cost (100%-20%)
Therefore you are multiplying 48 by .8
Your answer should be equal to $38.40
Answer:
The surface area of the second cylinder is equal to 
Step-by-step explanation:
we know that
If two figures are similar then
the ratio of their surfaces areas is equal to the scale factor squared
Let
z-------> the scale factor
x------> the surface area of the smaller cylinder (second cylinder)
y-------> the surface area of the original cylinder (first cylinder)
so

Step 1
Find the scale factor

Step 2
Find the surface area of the second cylinder
we have


substitute and solve for x
