Answer:
Step-by-step explanation:
The logistic function of population growth, that is, the solution of the differential equation is as follows:
We use this equation to find the value of r.
In this problem, we have that:
So we find the value of r.
Applying ln to both sides of the equality
So
The differential equation is
Because the problem stated that "the rancher plans to use 100 feet of fencing", we know that all of the sides of the fence must add up to 100 ft. Using this information, you set up an equation.
100=x+x+(x+4)+(x-3)+5 Then you combine like terms:
100=4x+6 Subtract 6 from both sides:
94=4x Divide both sides by 4:
23.5=x
Therefore, x=23.5 ft.
Answer:
E
Step-by-step explanation:
11x-4<15
11x<11
x<1
12x-7>-25
12x>-18
x>-3/2
x<1 or x>-3/2, that covers the whole x-axis domain
The given expression is
=ab+cd+ef+gh
The meaning of expression is equal to terms which contains variables and constants and operation between them is Addition, Subtraction, Multiplication and Division.
→The expression consists of four terms which are, ab, cd, ef, and gh.
→Each term contains
Two factors.

Answer:
-7x^2 +8x -10
Step-by-step explanation:
Combine like terms in the usual way.
(-3x^2 +5x -8) -(4x^2 -3x +2)
= -3^2 +5x -8 -4x^2 +3x -2
= (-3-4)x^2 +(5+3)x +(-8-2)
= -7x^2 +8x -10
