Answer:
Step-by-step explanation:
The equation given calculates the derivative of the height in relation to the time, that is, the rate of change of the height. To find the equation for the height, we need to integrate this equation:
Multiplying both sides by 'dt', we have:
Using the integral in both sides:
So the height after t years is represented by this equation:
Standard form is Ax + By = C
y = (-3/4)x - 2
Multiply both sides by 4.
4y = -3x - 8
Add 3x on both sides
3x + 4y = -8
Your final answer is 3x + 4y = -8.

Answer:
40 in
Step-by-step explanation:
For a width of w, the length is 3w and the area and perimeter are ...
A = LW = (3w)(w) = 3w^2
P = 2(L+W) = 2(3w +w) = 8w
We are given the area, so we can find w to be ...
75 in^2 = 3w^2
25 in^2 = w^2 . . . . . divide by 3
5 in = w . . . . . . . . . square root
Then the perimeter is ...
P = 8w = 8(5 in) = 40 in
