Your friend Susie goes into the same car dealership and tells them she has a budget of $300/month. She is interested in the same Chevy Cruze that is on sale for $16,000. She has a poor credit score and only qualifies for a 72-month 10% APR loan with No Down Payment. What is her monthly payment? Did she stay within budget?
How much would the car cost Susie after the loan has been paid in full?
Answers
Loan Amount = Monthly Payment x [(1 - (1 + Monthly Interest Rate)^-Number of Months) / Monthly Interest Rate]
where Monthly Interest Rate = (10%/12) = 0.0083 (since APR is annual percentage rate, we divide it by 12 to get monthly rate), Number of Months = 72, and Loan Amount = $16,000 (since she is not making any down payment).
Substituting the values:
$16,000 = Monthly Payment x [(1 - (1 + 0.0083)^-72) / 0.0083]
Solving for Monthly Payment:
Monthly Payment = $276.76 (rounded to the nearest cent)
Susie's monthly payment is within her budget of $300/month.
The total amount Susie will pay over the life of the loan is:
Total Amount Paid = Monthly Payment x Number of Months = $276.76 x 72 = $19,903.52
Therefore, the car will cost Susie a total of $19,903.52 after the loan has been paid in full.

You want to know which of the four offered tables represents a linear function.
DifferencesA linear function will have differences in y that have the same ratio to differences in x for all pairs of values in the table.
EvaluationTable A has x-differences that are 1 between adjacent terms. The y-differences are negative for the first pair of table values, but positive for the last pair (2 -5 vs 5 -2).
Table B has x-differences that are 1 between adjacent terms. The y-differences are -2 between any pair of adjacent terms, so their ratio to x-differences is -2/1 = -2, a constant. Table B represents a linear function.
Table C has x-differences that change from 0 to -3 to +3 while y-differences are constant at +1. The ratios of differences are not constant.
Table D has x-differences of +1, and y-differences that alternate in sign and magnitude.
Only Table B represents a linear function.

Answer:
x = 90
Step-by-step explanation:
The given diagram shows a circle with intersecting chords, KM and JL.
To find the value of x, we can use the Angles of Intersecting Chords Theorem.
According to the Angles of Intersecting Chords Theorem, if two chords intersect within a circle, the angle formed at the intersection point is equal to half the sum of the measures of the arcs intercepted by the angle and its corresponding vertical angle.
Let the point of intersection of chords KM and JL be point P.
As the chords are straight lines, angle x° forms a linear pair with angle JPM.
Note: We cannot use the Angles of Intersecting Chords Theorem to find the value of x directly, since we have not been given the measures of the arcs KJ and ML. Therefore, we need to use the theorem to find m∠JPM first.
From inspection of the given diagram:
\(m\overset\frown{JM}=30^{\circ}\)\(m\overset\frown{LK}=(2x - 30)^{\circ}\)Using the Angles of Intersecting Chords Theorem, we can calculate the measure of angle JPM (shown in orange on the attached diagram):
\(\begin{aligned}m \angle JPM &=\dfrac{1}{2}\left(m\overset\frown{JM}+m\overset\frown{LK}\right)\\\\&=\dfrac{1}{2}\left(30^{\circ}+(2x-30)^{\circ}\right)\\\\&=\dfrac{1}{2}\left(30^{\circ}+2x^{\circ}-30^{\circ}\right)\\\\&=\dfrac{1}{2}\left(2x^{\circ}\right)\\\\&=x^{\circ}\end{aligned}\)
As angle JPM forms a linear pair with angle x°, the sum of the two angles equals 180°:
\(\begin{aligned}m \angle JPM+x^{\circ}&=180^{\circ}\\\\x^{\circ}+x^{\circ}&=180^{\circ}\\\\2x^{\circ}&=180^{\circ}\\\\\dfrac{2x^{\circ}}{2}&=\dfrac{180^{\circ}}{2}\\\\x^{\circ}&=90^{\circ}\\\\x&=90\end{aligned}\)
Therefore, the value of x is 90, which means that the two chords intersect at right angles.
What are the exact steps to solve for the x-intercepts of f(x)= −4x2 + 4x + 8? What about −9 = x2 + 6x? Please explain thoroughly
Answers
Answer:
x-intercepts: (-1, 0) and (2, 0)
x-intercept: (-3, 0)
Step-by-step explanation:
Given quadratic function:
\(f(x)=-4x^2+4x+8\)
The x-intercepts of a quadratic function are the points at which the curve crosses the x-axis ⇒ when y = 0
Therefore, to find the x-intercepts of the given function, set the function to zero:
\(\implies -4x^2+4x+8=0\)
Factor out -4:
\(\implies -4(x^2-x-2)=0\)
Divide both sides by -4
\(\implies x^2-x-2=0\)
Rewrite the middle term as -2x + x:
\(\implies x^2-2x+x-2=0\)
Factor the first two terms and the last two terms separately:
\(\implies x(x-2)+1(x-2)=0\)
Factor out the common term (x - 2):
\(\implies (x+1)(x-2)=0\)
Zero Product Property: If a ⋅ b = 0 then either a = 0 or b = 0 (or both).
Using the Zero Product Property, set each factor equal to zero and solve for x (if possible):
\(\begin{aligned}(x+1) & = 0 & \quad \textsf{ or } \quad \quad (x-2) & = 0\\\implies x & = -1 & \implies x & = 2\end{aligned}\)
Therefore, the x-intercepts are (-1, 0) and (2, 0).
---------------------------------------------------------------------------------------
Given quadratic equation:
\(-9 = x^2 + 6x\)
Add 9 to both sides:
\(\implies x^2+6x+9=0\)
Rewrite the middle term as 3x + 3x:
\(\implies x^2+3x+3x+9\)
Factor the first two terms and the last two terms separately:
\(\implies x(x+3)+3(x+3)=0\)
Factor out the common term (x + 3):
\(\implies (x+3)(x+3)=0\)
\(\implies (x+3)^2=0\)
Square root both sides:
\(\implies (x+3)=0\)
Solve for x:
\(\implies x=-3\)
Therefore, the x-intercept is (-3, 0).
As the function has a repeated factor (multiplicity of two), the curve will touch the x-axis at (-3, 0) and bounce off.

Step-by-step explanation:
∠A ≅ ∠B
as ACB is a triangle
if ∠A ≅ ∠B then AC = BC
and CD ⊥ AB
so ∠CDA = ∠CDB = 90
now in ΔADC ---> ∠A + ∠CDA + ∠ACD = 180
lets assume ∠A = x = ∠B
x + 90 + ∠ACD = 180
∠ACD = 180 - 90 - x
∠ACD = 90 - x
now in ΔCDB ---> ∠B + ∠CDB + ∠BCD = 180
x + 90 + ∠BCD = 180
∠BCD = 180 - 90 - x
∠BCD = 90 - x

Simplify the rational expression
7x/14x^6
Answers
The simplified form of the rational expression \((7x)/(14x^6)\) is \(1/(2x^6).\)
To simplify the rational expression \((7x)/(14x^6)\), we can begin by simplifying the numerator and denominator separately.
In the numerator, 7x, we can see that both 7 and x have a common factor of 7. So, we can rewrite the numerator as 7 × x = 7x.
In the denominator, \(14x^6\), we can see that both 14 and x^6 have a common factor of \(2x^6\).
So, we can rewrite the denominator as
\(14 \times x^6 = 2 \times 7 \times x^6 = 2 \times 7x^6.\)
Now, we can simplify the rational expression by canceling out the common factors in the numerator and denominator:
\((7x)/(14x^6) = (7x)/(2 \times 7x^6) \\= (7x)/(2 \times 7 \times x^6) \\= (cross(7x))/(2 \times cross(7) \times x^6) \\= 1/(2x^6)\)
Therefore, the simplified form of the rational expression\((7x)/(14x^6)\) is \(1/(2x^6).\)

In a study of the accuracy of fast food drive-through orders, Restaurant A had 240 accurate orders and 73 that were not accurate.
A. Construct a 90% confidence interval estimate of the percentage of orders that are not accurate.
b. Compare the results from part (a) to this 90% confidence interval for the percentage of orders that are not accurate at Restaurant B: 0.211 < P <0.292. What do you conclude?
Construct a 90% confidence interval. Express the percentages in decimal form.
(Round to 3 decimal places as needed)
___< P <___
Answers
Part A
p = population proportion of inaccurate orders for restaurant A.
There are 240 accurate orders and 73 inaccurate ones.
That gives 240+73 = 313 total orders.
n = 313 = sample size
73/313 = 0.233227 is the approximate sample proportion of inaccurate orders. This is the approximate value of phat. The job of phat is to estimate p.
At 90% confidence, the z critical value is roughly z = 1.645; use a stats table, reference sheet, or calculator to find this value.
Let's calculate the margin of error.
E = margin of error
E = z*sqrt(phat*(1-phat)/n)
E = 1.645*sqrt(0.233227*(1-0.233227)/313)
E = 0.039320 approximately
Then,
L = lower boundary of confidence interval
L = phat - E
L = 0.233227 - 0.039320
L = 0.193907
L = 0.194
And
U = upper boundary of confidence interval
U = phat + E
U = 0.233227 + 0.039320
U = 0.272547
U = 0.273
The 90% confidence interval for the inaccurate order rate of restaurant A is therefore 0.194 < p < 0.273
We are 90% confident the population proportion p is somewhere between 0.194 and 0.273
=================================================
Part B
The result of part A was 0.194 < p < 0.273
Compare this to 0.211 < p < 0.292 for restaurant B.
Use a number line to see that there is overlap between these intervals. It's possible that both restaurants might have the same inaccurate order rates (or close to the same).
If there wasn't an overlap, then it would be likely the two rates would be different.

How far, in kilometers, is the trip to the airport?
Answers
Given:
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport.
The total charge is AED 135.
To find:
How far, in kilometers, is the trip to the airport?
Solution:
Let x km be the trip to the airport.
A taxi service charges AED 10 plus AED 250 per kilometer for a trip to the airport. So, total changes for x km trip is
\(T=10+250x\)
The total charge is AED 135.
\(10+250x=135\)
\(250x=135-10\)
\(250x=125\)
Divide both sides by 250.
\(x=\dfrac{125}{250}\)
\(x=\dfrac{1}{2}\)
\(x=0.5\)
Therefore, the trip to the airport is 0.5 km.

Ana works 25 hours a week at the library. If she is paid $10 an hour, and her net salary each week is $212.50, what percent of her salary is withheld for taxes?
Answers
Approximately 17.65% of Ana's salary is withheld for taxes.
To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.
Number of hours worked per week (H) = 25 hours
Hourly wage (W) = $10
Net salary (S) = $212.50
Calculate the total earnings before taxes:
Total earnings = Hours worked * Hourly wage
Total earnings = 25 hours * $10/hour
Total earnings = $250
Determine the amount of tax withheld:
Tax withheld = Total earnings - Net salary
Tax withheld = $250 - $212.50
Tax withheld = $37.50
Calculate the percentage of salary withheld for taxes:
Percentage withheld = (Tax withheld / Net salary) * 100
Percentage withheld = ($37.50 / $212.50) * 100
Percentage withheld ≈ 17.65%
Therefore, approximately 17.65% of Ana's salary is withheld for taxes.
