Answer: dy/dt 2y = 4
Explanation:
The differential equation can be found by taking the derivative of y with respect to t of both sides of this equation.
Derivative of y^2 becomes 2y * dy/dt.
4(t+1) can be distributed to equal 4t + 4.
Derivative of 4t + 4 becomes 4.
Therefore, a possible differential equation is dy/dt * 2y = 4. Can check by separating and integrating.

If Manny's initial money in the savings account is x, we are to calculate for the period in which Manny's money becomes 2x. The calculations are shown
2x = x (1.045)^n
Cancelling both x from the equation and the computing for value of n will give us an answer of 15.75 years.
Answer:28000 B
Step-by-step explanation:
10^4 is 10000
2.8*10000 is 28000
An hourglass is turned over with the top part filled with
sand. after 3 minutes, there are 855 ml of sand in the top half. after 10
minutes, there are 750 ml of sand in the top half. This can be represents a two
points ( 3, 855) and (10, 750) . using this to solve the slope m =
(750-855)/(10-3) = -15. And using one point the equation is y = -15x + 900.
