Answer:
84ft
Step-by-step explanation:
w = 2/3(L)
if 280 feet of fencing can enclose the garden,therefore the perimeter is 280 feet
perimeter = 2L + 2W
but W=2/3(L)
therefore, perimeter = 2L + 2(2/3L)
P= 2L + 4/3(L)
P= 10/3(L)
but P= 280
therefore 280= 10/3(L)
L = (3×280)÷10
L= 84 feet
24yards
2x-3=y
y=2*2-3=
y=4-3
y=1
A.
Step-by-step Explanation:
P(A or B) = P(A)+P(B)-P(A and B)
Now
Putting the givens
0.68 = 0.2 + P(B) - 0.12
P(B) = 0.68 - 0.2 +0.12
P(B) = 0.6
The ODE has an equilibrium point at
We want to be an unstable equilibrium solution - in other words, we want all solutions with initial condition for near 2 to diverge from - so .
Divergence from would require that for , any solution is increasing, and for , and solution is decreasing. In order for that to happen, we need
if , and
if .
Now we just pick to satisfy these conditions. An easy choice is , which forces , so that one possible ODE would be
I've attached a plot of the slope field to demonstrate the behavior of the solutions.
