Answer:
21, 15
Step-by-step explanation:
12+9=21
the third side of a triangle must be equal to the two other sides added up to make it possible
also 15 if you're trying to make a possible right triangle
The general solution, y(t), which solves the problem by the method of integrating factors is; y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)
<h3>How to solve differential equations?</h3>
We want to find the general solution of;
5t(dy/dt) + y = t⁴
We will divide through by 5t to get;
(dy/dt) + y/5t = t³/6
Using Integration factor, we have;
u(t) = e^∫(¹/₅t) dt = t^(¹/₅)
Thus, we now have;
[t^(¹/₅)](dy/dt) + [t^(¹/₅)]y/5t = [t^(¹/₅)]t³/6
Completing this with a differential calculator gives us the general solution as;
y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)

Answer:
a, b, d and f
Step-by-step explanation:
To find which equation will have a a mass less than 50 mg after 2 hours, we just need to use the value of x = 2 and then verify if the values of y are less than 50:
a. y = 100*(0.5)^2 = 25 -> apply
b. y = 500*(0.3)^2 = 45 -> apply
c. y = 80*(2)^2 = 320 -> doesn't apply
d. y = 10*(1.2)^2 = 14.4 -> apply
e. y = 30*(1.5)^2 = 67.5 -> doesn't apply
f. y = 80*(0.2)^2 = 3.2 -> apply
g. y = 100*(2)^2 = 400 -> doesn't apply
