Answer:
A. 54°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
y + y + 72 = 180
2y + 72 - 72 = 180 - 72
2y = 108
(2y)/2 = 108/2
y = 54
Answer:
c
Step-by-step explanation:
dP / dt = P / 10
We apply separable variables:
dP / P = dt / 10
We integrate both sides:
Ln (P) = t / 10 + C
We rewrite the equation:
Exp (Ln (P)) = Exp (t / 10 + C)
P = Exp (C) * Exp (t / 10)
P = C * Exp (t / 10)
We look for the constant using:
P (0) = 300
300 = C * Exp (0/10)
300 = C * 1
C = 300
We rewrite the equation:
P = 300 * Exp (t / 10)
After 40 hours we have:
P = 300 * Exp (40/10)
P = 16379.44501
Answer:
the population size after 40 hours is:
P = 16379
The correct answer is:
(x,y) = (6,2)
Option A would be the correct one.
Answer:
because of equvalent property
