Use a compass and straight edge to create a line parallel to line AB through a point E that is not on line AB. First, draw a line from point E that crosses line AB, and label the intersection point C. Which step comes next?
- Set the compass point on A and draw an arc of any size across line .
- Move the compass point to the upper arc and mark off an arc, creating point D.
- Set the compass width to the width of the arc that crosses line .
- Place the point of the compass on C and draw an arc that crosses both lines.
Answer:
Step-by-step explanation:
The given steps describe constructing a parallel line using a compass and straightedge given line and a point E that is not on line .
Step 1: Draw a line through point E that intersects line , and label the point of intersection, C.
Step 2: Place the point of the compass on C and draw an arc that crosses both lines.
Step 3: Without adjusting the compass width, move the compass to point E and draw an arc that has a similar orientation to the first arc drawn.
Step 4: Set the compass width to where the lower arc crosses the two lines.
Step 5: Move the compass point to the upper arc on the intersection of the arc and line .
Step 6: Draw an arc so it intersects the bottom of the arc. Label the intersection D.
Step 7: Use a straightedge to connect points E and D to form the parallel line .
so the answer is Place the point of the compass on C and draw an arc that crosses both lines

The total amount of purchases of Rollie is $1,251. Rollie's available credit card limit after spending $1,251 from $4,000 is $2,749.
We are given:
Rollie has a credit card limit of $4,000.
He made the following purchases: $425.36, $358.33, $377.11, and $90.20.
We need to find the total amount of purchases and Rollie's available credit card limit.
To find the total amount of purchases, we need to perform the addition that is add all the expenses:
The total amount of purchases
= addition of all purchases
= $425.36 + $358.33 + $377.11 + $90.20
= $1251
We need to subtract the total amount of purchases from the credit card limit to get Rollie's available credit card limit.
So,
Rollie's available credit card limit
= credit card limit - the total amount of purchases
= $4000 - $1251
= $2749
Thus, the total amount of purchases of Rollie is $1,251. Rollie's available credit card limit after spending $1,251 from $4,000 is $2,749.

Roberto is applying for a mortgage. He has a monthly gross income of $3,500. The home he would like to buy has monthly payments for the following: $1,000 mortgage, $150 property taxes, $75 homeowners insurance premium, and $75 mortgage insurance premium. Roberto also has other monthly debts totaling $500 per month. Based on the Federal Housing Administration (FHA) total fixed payments-to-income ratio, would he qualify for the mortgage loan?
Based on the Federal Housing Administration's (FHA) total fixed payments-to-income ratio, Roberto would not qualify for the mortgage loan.
What is the fixed payments-to-income ratio?The Federal Housing Administration (FHA) allows 31% of a person's income to settle housing costs (as the front-end ratio) and 43% (as the back-end ratio) towards housing expenses and other long-term debt.
Monthly gross income = $3,500
Monthly payments for Housing:
Monthly mortgage = $1,000
Property taxes = $150
Homeowners insurance premium = $75
Mortgage insurance premium = $75
Total monthly housing costs = $1,300
Other monthly debts per month = $500
Total monthly payments = $1,800
Minimum front-end ratio = 31% = $1,085 ($3,500 x 31%)
Maximum back-end ratio = 43% = $1,505 ($3,500 x 43%)
Thus, using the FHA fixed payments-to-income ratio, Roberto would not qualify.

The student academic group on a college campus claims that freshman students study at least 2.5 hours per day, on average. One Introduction to Statistics class was skeptical. The class took a random sample of 30 freshman students and found a mean study time of 135 minutes with a standard deviation of 44 minutes. At
= 0.01 level, is the student academic group's claim correct?
1. What is the p-value
The p-value of this sample proportion is equal to 0.0360.
At the 0.01 (1%) significance level, there isn't enough evidence to conclude that freshmen students study less than 2.5 hours per day, on an average.
How to calculate value of the test statistic?For this statistical study, we would use a t-test statistic and the null and alternative hypotheses would be given by:
H₀: p ≥ 150 minutes
H₁: p < 150 minutes
Mathematically, the t-test statistic can be calculated by using this formula:
[tex]t=\frac{x\;-\;\mu}{\frac{\delta}{\sqrt{n} } }[/tex]
Where:
x represents the sample mean.μ represents the mean.σ represents the standard deviation.n represent the number of students.Substituting the given parameters into the formula, we have;
t-test, t = (135 - 150)/(44/√30)
t-test, t = (-15)/8.0333
t-test, t = -1.8672
From the t distribution table, the p-value is given by:
p-value = P(t < -1.8672)
p-value = 0.0360
Since the p-value (0.0360) is greater than the significance level (0.01), we fail to reject the null hypothesis because there is insufficient evidence to claim that the mean time of the freshman students is less than 2.5 hours per day.

NO LINKS!! Please help me with this symmetry part 3 Select all that apply
Answer:
[tex]y=-\dfrac{1}{8}x^3[/tex]
Step-by-step explanation:
If a function is symmetrical about the origin, when y is replaced with (-y) and x is replaced with (-x), the resulting function will be equal to the original function.
Original function:
[tex]y=-\dfrac{1}{8}x^3[/tex]
Replace y with (-y) and x with (-x):
[tex]\implies -y=-\dfrac{1}{8}(-x)^3[/tex]
[tex]\implies -y=-\dfrac{1}{8}\cdot -x^3[/tex]
[tex]\implies -y=\dfrac{1}{8}x^3[/tex]
Multiply both sides by -1:
[tex]\implies y=-\dfrac{1}{8}x^3[/tex]
Therefore, as the function is equal to the original function, this function is symmetric with respect to the origin.

5. If you were told that a specific tire could roll 200 yards in 27.28 revolutions, what is the radius of the tire?
The number of revolutions = Total distance divided by its circumference
The radius of the tire is 1.167 yards.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of
2πr.
The area of a circle is given as πr².
We have,
The number of revolutions = Total distance divided by its circumference
Total distance = 200 yards
Revolutions = 27.28
A tire is in the form of a circle.
So,
The circumference of the tire.
= 2πr
Now,
27.28 = 200 yards / 2πr
2πr = 200 yards / 27.28
r = 200/(27.28 x 2 x 3.14)
r = 200 / 171.32
r = 1.167 yards.

Answer: (0,0) (12,0)
Step-by-step explanation:
y=4x³-96x²+576x
Let y=0
Hence,
4x³-96x²+576x=0
Divide both parts of the equation by 4:
x³-24x²+144x=0
x(x²-24x+144x)=0
x=0
Thus, (0,0)
x²-24x+144=0
x²-2(x)(12)+12(12)=0
x²-2(x)(12)+12²=0
(x-12)²=0
x-12=0

We have the following information:
JK has endpoints J(-10, 1) and K(2, -2). Point L divides JK into two parts with lengths in a ratio of 2:1.
We know that the following formulas are used to find the coordinates of a point:

What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
