Factor the 25 where they multiply to make 25 and add to make 10 so now it's (x+5)and (x+5) so x=-5 because x+5=0 solved
Step-by-step explanation:
a)
dy/dx = 4x √(1 − y²)
Separate the variables:
dy / √(1 − y²) = 4x dx
Integrate:
sin⁻¹ y = 2x² + C
Solve for y:
y = sin(2x² + C)
b)
Plug in initial value.
4 = sin(0 + C)
Sine cannot be greater than 1, so there is no solution.
So for this we need to convert the word problem into an equation, and it'll look like this:
(n=number). And from there, we can solve.
Multiply 2 and (n+11) and your equation should look like
Add 22 on each side, and your equation should look like
Subtract 2n on each side, and your answer should should be
Answer:
c = 13 years (youngest)
---
a = 2c = 26 years (oldest)
----
b = c+5 = 18 years (middle)
