Recall the Triangle Midsegment Theorem:
This implies that since BE is a midsegment of the triangle (as B and E are midpoints), then:
\(BE=\frac{1}{2}CD\)
Substitute BE=5 into the equation and solve for CD:
\(\begin{gathered} 5=\frac{1}{2}CD \\ \Rightarrow CD=5\times2=10 \end{gathered}\)
Since the point B is a midpoint, it follows by definition that:
\(\begin{gathered} BC=AB,\text{ but AB=3} \\ \Rightarrow BC=3 \end{gathered}\)Also, E is a midpoint of AD, it follows that:
\(\begin{gathered} ED=\frac{1}{2}AD \\ \Rightarrow ED=\frac{1}{2}\times8=4 \end{gathered}\)The perimeter of BCDE is the sum of all sides:
\(P=BC+CD+ED+BE\)Substitute the length of the sides:
\(P=3+10+4+5=22\text{ units}\)The perimeter of BCDE is 22 units.

The location of point A''' after the three transformations would be (-4, 1).
To determine the location of point A''', we need to apply the three transformations (reflection over the y-axis, reflection over the x-axis, and rotation of 180°) to point A.
When a point is reflected over the y-axis, the x-coordinate is negated while the y-coordinate remains the same.
So, the reflection of point A (-4, 1) over the y-axis would be (4, 1).
When a point is reflected over the x-axis, the y-coordinate is negated while the x-coordinate remains the same. So, the reflection of point (4, 1) over the x-axis would be (4, -1).
When a point is rotated 180°, the x-coordinate and y-coordinate are both negated. So, the rotation of point (4, -1) by 180° would be (-4, 1).

A rectangular carpet has a perimeter of 264 inches. The length of the carpet is 108 inches more than the width. Determine the dimensions of the carpet by solving the equation 2w+2(w+108)=264, where w represents the carpet width.
Answer:
The width of the carpet is 12 inches and the length of the carpet is 120 inches.
Step-by-step explanation:
\(2w+2(w+108)=264\)
^We can distribute first^
Distributing would result in:
\(2w+2w+216=264\)
Then we would combine like terms, which would result in:
\(4w + 216 = 264\)
Then we solve the equation.
\(4w + 216 = 264 \\ \: \: \: \: \: \: \: \: \: \frac{ - 216 = - 216}{4w = 48} \\ \\ \frac{4w}{4} = \frac{48}{4} \\ w = 12\)
Since the width of the carpet is 12 (as we figured out). The statement said that "The length of the carpet is 108 inches more than the width."
So now we add 108 to 12 to figure out the length.
\(108 + 12 = 120\)
The length of the carpet is 120 inches.

Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592. What equal monthly payments (in $) must Eric make in order to pay back the loan, with interest, in 36 months?
Answer:
He will pay $922 Eve month where
$238.6667 is the interest in the payment
Step-by-step explanation:
Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592 to be paid back in 36 months monthly.
Total money to be paid back
= 24600+8592
Total money to be paid back
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= 33192/36
= $922
But if the interest wasn't added
He'll pay= 24600/36
=$683.333
So the interest amount in the payment every month= 922-683.333.
= $238.6667
He will pay $922 Eve month where
$238.6667 is the interest in the payment
The calculation is as follows:Total money to be paid back
= 24600+8592
= $33192
Now for each month in 36 months, a certain amount must be paid
That amount= \(33192\div36\)
= $922
Now in the case when the interest wasn't added
He'll pay= \(24600\div 36\)
=$683.333
So the interest amount in the payment every month is
= 922-683.333.
= $238.6667

The answer is D.
Step-by-step explanation:
Answer: 11 weeks
Step-by-step explanation:
First we need to check what variables we have.
Beginning Balance = $1000
Goal = $350
Withdrawal = $55 per week
Now let's declare a variable as the number of weeks.
Let x = number of weeks
1000 - 55x = 350
-55x = 350-1000
-55x = -650
Then we divide both sides by -55 to find the value of x.
x = 11.81 or 11 since we're looking for how many weeks in total
Now let's see if we still have 350 if we have a total of 11 as the value of x.
1000 - 55(11) = 350
1000 - 605 = 350
395 = 350
We can see that Kendall will have $395 compared to the $350 goal.
So Kendall can withdraw $55 a week for 11 weeks to still be within her goal of having $350 in her savings account.

5. Find the domain and the range for each of the following graphs.
Answer:
Domain: x \(\geq\) -5
Range: y \(\geq\) -3
Step-by-step explanation:
The domain is all the possible inputs or x value. x will be greater than -5.
The range is all of the possible outputs or y value. y will be greater than -3
Answer:
Domain: [-5, ∞)
Range: [-3, ∞)
Step-by-step explanation:
The given graph shows a continuous curve with a closed circle at the left endpoint (-5, -3) and an arrow at the right endpoint.
A closed circle indicates the value is included in the interval.
An arrow shows that the function continues indefinitely in that direction.
DomainThe domain of a function is the set of all possible input values (x-values).
As the leftmost x-value of the curve is x = -5, and it continues indefinitely in the positive direction, the domain of the graphed function is:
Interval notation: [-5, ∞)Inequality notation: x ≥ -5Set builder notation: {x ∈ R | x ≥ -5 }RangeThe range of a function is the set of all possible output values (y-values).
From observation, it appears that the minimum y-value of the curve is y = -3. The curve continues indefinitely in the positive direction in quadrant I. Therefore, the range of the graphed function is:
Interval notation: [-3, ∞)Inequality notation: y ≥ -3Set builder notation: {y ∈ R | y ≥ -3 }1. Global warming creates local problems. Projections forecast that even a moderate air temperature increase of only 1.8 °F could cause brook trout distributions to decrease dramatically. For example, such a temperature increase would take Washburn county's 19 ponds that support brook trout down to 10 ponds. What would be the percent decrease in the number of ponds that support brook trout?
The percent decrease in the number of ponds that support brook trout would be approximately 47.37%.
To calculate the percent decrease in the number of ponds that support brook trout, we need to determine the difference between the initial number of ponds and the final number of ponds, and then express that difference as a percentage of the initial number of ponds.
Initial number of ponds: 19
Final number of ponds: 10
To calculate the percent decrease, we can use the following formula:
Percent Decrease = (Difference / Initial Value) * 100
Let's apply this formula to the given data:
Difference = Initial number of ponds - Final number of ponds
Difference = 19 - 10
Difference = 9
Percent Decrease = (9 / 19) * 100
Now, let's calculate the percent decrease:
Percent Decrease = (9 / 19) * 100
Percent Decrease ≈ 47.37%

Find a and b using the factor theorem.
\(f(x)=x^3+ax^2+bx-12\) has factor \((x-1), (x+1)\)
The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.
To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

"The correct option is C." The only expression that is equivalent to log 2 - log 4 is option C: log(2) + log(¹).
The expression "log 2 - log 4" can be simplified using logarithmic properties. Specifically, the property states that "log(a) - log(b) = log(a/b)." Applying this property to the given expression, we have "log 2 - log 4 = log(2/4) = log(1/2) = -log(2)."
The expression log 2 - log 4 can be simplified using logarithmic properties. Let's analyze each option:
A. log(¹): This expression is not equivalent to log 2 - log 4. The logarithm of 1 is 0, but it does not cancel out the terms log 2 and log 4.
B. log 1: This expression is equivalent to 0, but it does not cancel out the terms log 2 and log 4.
