The population of squirrels in the Louisiana forest growing monthly at a rate of 5% currently from 100, will be 182 after a year.
The final value of any quantity growing constantly at a particular rate is given as [tex]V = V_{0}e^{rt}[/tex] ,
where V is the final value, V₀ is the initial value, r is the rate of growth per time period, and t is the number of time periods.
The current population of squirrels (V₀) = 100.
The growth rate (r) = 5% per month.
The time period (t) = 1 year = 12 months.
Hence, the final population of squirrels (V), is given as:
[tex]V = V_{0}e^{rt}[/tex] ,
or, [tex]V = 100e^{(0.05*12)}[/tex] ,
or, [tex]V = 100e^{0.60}[/tex] ,
or, V = 100*1.822119,
or, V = 182.2119 ≈ 182.
Therefore, the population of squirrels in the Louisiana forest growing monthly at a rate of 5% currently from 100, will be 182 after a year.

Answer:
○ The distance between a and b on the number line is 0.47 units.
Explanation:
The first statement is not true because the distance between a and b on the number line is not 0.47.
Distance between a and b = 5.25 - (-5.72)
= 10.97
• The second statement is true because the sum of a and b is negative:
Sum = a + b
= -5.72 + 5.25
= -0.47
• The third statement is true because the quotient of a and -b is:
a ÷ -b
⇒ -5.72 ÷ -5.25
⇒ 1
And the quotient of -a and b is:
-a ÷ b
⇒ -(-5.72) ÷ 5.25
⇒ 1
This shows that the quotients are the same.
• The fourth statement is true because the product of a and -b:
a × -b
⇒ -5.72 × -(5.25)
⇒ 30.03 ,
is positive.
Eden just bought a trough in the shape of a rectangular prism for her horses. She needs to know what volume of water to add to the trough. She knows that the height of the trough is 13 inches shorter than the width, and that the length is 33 inches longer than the width.
The volume of the trough, V(w), can be modeled by a polynomial function, where w is the width of the trough. Which of the following correctly models the situation and gives the rate of change of the volume over a width of 38 inches to 53 inches?
A. V(w)= w^3 + 20w^2 - 429w
Rate of Change: 2167 cubic inches per inch
B. V(w)= w^3 + 20w^2 - 429w
Rate of Change: 7658 cubic inches per inch
C. V(w)=w^2 + 429w
Rate of Change: 520 cubic inches per inch
D. v(w) = w^2 + 20w - 429
Rate of Change: 111 cubic inches per inch
The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let w represent the width, hence:
length = w + 33, height = w - 13
Volume (V) = w(w + 33)(w - 13) = w³ + 20w² - 429w
V(w) = w³ + 20w² - 429w
Rate of change = dV/dw = 3w² + 40w - 429
When w = 38, dV/dw = 3(38)² + 40(38) - 429 = 5423
When w = 53, dV/dw = 3(53)² + 40(53) - 429 = 10118
Rate = 10118 - 5423 = 4695 in³/in
The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in

How to find the surface area?A solid object's surface area is a measurement of the overall space that the object's surface takes up. Compared to the definition of the arc length of a one-dimensional curve or the definition of the surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is much more complex.
Let s be the side of the square base and h be the height.
Surface Area=[tex]s^{2}+4sh[/tex]
Volume=[tex]s^{2}h[/tex]
According to the question,
[tex]s^{2}h=1372\\ h=\frac{1372}{s^{2} }[/tex]
So, surface area=[tex]s^{2} +4s(\frac{1372}{s^{2} })[/tex]

Alice is playing a game in which she will roll 4 6-sided dice at the same time. She gets 5 points for each die that shows an even result. Let x represent the total number of points awarded on any given toss of the dice. What is the expected value of x
The expected value of x is 10.
It is given that the number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable.
Thus E(X) = 5*2 = 10.

B.
The maximum value of d is 3 less than the minimum value of c.
C.
The minimum value of d is 3 more than the maximum value of c.
D.
The minimum value of d is 5 more than the maximum value of c.
Answer:
d - the minimum value of d is 5 more than the maximum value of c
Step-by-step explanation:
we can see from the graph that d has a minimum value
that value is at (-1, 2) and the minimum is 2
for c the vertex is where the graph reflects itself
that point is (-4, -3) and the maximum is -3
that means that the minimum value of d is 5 more than the maximum value of c because 2 - (-3) = 5

Which of the following equations results in infinitely many solutions?
9x80 = 8(x + 10)
9x + 10- 1x = 8(x + 10)
9x + 80 1x = 8(x + 10)
9x + 80 1x = 9(x + 10)
The equation with infinitely many solutions is:
9x + 80 - 1x = 8*(x + 10)
Which equation has infinitely many solutions?
An equation has infinitely many solutions when the dependence on x vanishes.
If you look at the third equation, we get:
9x + 80 - 1x = 8*(x + 10)
If we simplify the left side and expand the right side, we get:
8x + 80 = 8x + 80
So we have the exact same thing in both sides, this means that the equation is true for any value of x, so the equation has infinite solutions.

Step-by-step explanation:
L = larger softball and S = smaller softball ,then
L + S = 80 → (1) ← equation based on number of softballs ordered
2.75L + 3.25S = 245 → (2) ← equation based on cost
subtract S from both sides in (1)
L = 80 - S → (3)
substitute L = 80 - S into (2)
2.75(80 - S) + 3.25S = 245 ← distribute parenthesis and simplify left side
220 - 2.75S + 3.25S = 245
220 + 0.5S = 245 ( subtract 220 from both sides )
0.5S = 25 ( divide both sides by 0.5 )
S = 50
substitute S = 50 into (3)
L = 80 - 50 = 30
50 small softballs and 30 large softballs were ordered
Answer:
the 4th answer option
Step-by-step explanation:
L, S are the number of balls of that size.
so, L + S = 80. as we order a total of 80 balls.
then each large ball costs $2.75. and each small ball costs $3.25.
so, the total price is
2.75L + 3.25S = 245
as we order balls in total for $245.
so, this set of 2 equations with 2 variables allows us to find the solution.
one defines the total number of balls, and one defines the total amount of money spent by using the individual prices for each type of ball.
the advantage of variables is that we can define the rising and dependencies before we have to calculate any of them specifically.
and once we have all of them defined, then we can start solving the numbers.
