<h3>Given</h3>
p'(t) = kp²
p(0) = 12; p(10) = 24
<h3>Find</h3>
a) p(t)
b) t such that p(t) = 48
c) the behavior of p(t) after the time of part b
<h3>Solution</h3>
a) The differential equation is separable, so can be solved by separating the variables and integrating.
Plugging in the given boundary conditions, we can solve for k and C to find
b) The population doubles when the time to t=20 is cut in half. The first doubling occurred in 10 years; the second one will occur in half that time, 5 years. There will be 48 alligators in the swamp in 2003.
c) The population doubles again in half the time of the previous doubling, so is predicted to be infinite in 2008.
Let say that:
side one = A
side two = B
side three = C
And also, A+B+C = 80
Then, from that information we can get..
A=4B ; C=A-10... We can get the value of A, but we have to modified some equation.
Let, B=1/4 A.... (eq.1)
C=A-10.... (eq.2)
If we adding eq.1 and eq.2 we get:
B+C = 2A-39/4
Therefore,
A= 80 - (B+C)
A = 80 - 2A + 39/4
3A = 80 + 39/4
3A = 359/4 (Dividing both sides with 3)
A = 359/12 = 29.92
B = 1/4 A = 359/48 = 7.48
C = 359/12 - 10 = 19.92
Answer:
78 I think is the ans if x
The prime factorization number is 280 I got 2.2.5.7
Answer:
slope:7.5, y-intercept:50
Step-by-step explanation:
The basic equation for slope is y=kx+b
In this equation, k stands for slope and b stands for y-intercept.
So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50
