I believe it is the first one because it is an exponential growth rate.
If the value was initially v, then after a year it is 0.75v, after 2 years it’s 0.75²v, and so on. So after 6 years it’s 0.75⁶v.
So 0.75⁶v=7500, and v=7500/0.75⁶=$42,139.92 approximately. This is close to $42,140.
Add another triangle to make it a square/rectangle. Then find the perimeter of that. Then divide the answer by 2. That will be the perimeter of the shape.
Answer: Both calculated the volume properly.
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:
Where <em>r</em> is the radius and <em>h</em> is the height.
You know that the radius of the cyclindrical swimming pool is 13 feet and the height is 6 feet.
Substitute these values into the formula. Then, the volume is:
or
Therefore, both calculated the volume properly.
First we write equation for perimeter of rectangle. Why? because we have been given that it is 128 units and maybe we can calculate something from it.
P = 2a + 2b where
a = 2(3y + 1 ) and b = 2(2y +3)
P = 6y + 2 + 4y + 6 = 10y + 8 = 128
now we can solve for y
10y = 120
y = 12
Now we just express value of y in formula for finding lenght of VW and we got length
Answer is 37
