Credit card A has an APR of 20.8% and an annual fee of $60, while credit card
B has an APR of 24.6% and no annual fee. All else being equal, which of these
equations can be used to solve for the principal, P, the amount at which the
cards offer the same deal over the course of a year? (Assume all interest is
compounded monthly.)
The amount at which the cards offer the same deal over the course of a year is a $2,333.33
Since credit card finance charge is the fee associated with using credit.
Credit card issuers use the finance charges to minimize non-payment risks and earn some profits for extending credit to cardholders.
Data and Calculations:
Card A Credit B
APR 20.8% 24.6%
Annual fee $60 $0
To calculate the balance required, the required equation is
= 22%x + $40 = 24.6%x
Where x = required balance
Thus,
= 0.208x + $60 = 0.246x
= $60 = 0.03x (0.246x- 0.208x )
= 0.03x = $60
x = $60 /0.03
x = $2,333.33

Find the slope and y intercept of the line 5x-9y=45
Answer:
slope = [tex]\frac{5}{9}[/tex] , y- intercept = - 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
5x - 9y = 45 ( subtract 5x from both sides )
- 9y = - 5x + 45 ( divide through by - 9 )
y = [tex]\frac{-5}{-9}[/tex] x + [tex]\frac{45}{-9}[/tex] , that is
y = [tex]\frac{5}{9}[/tex] x - 5 ← in slope- intercept form
with slope m = [tex]\frac{5}{9}[/tex] and y- intercept c = - 5

Step-by-step explanation:
Suppose you want to buy a $160,000 home. You found a bank that offers a 30-year loan at 3.3% APR.
What will be your monthly payment? (Round to the nearest cent.)
$
How much would you end up paying the bank for the home after 30 years? (Round to the nearest cent.)
$
Suppose you wanted to reduce the time of your loan to 25 years. What would be your new monthly payment? (Round to the nearest cent.)
$
How much would you end up paying the bank for the home after 25 years? (Round to the nearest cent.)
$
How much did you save by reducing the time of your mortgage loan? (Round to the nearest cent.)
$
The required solution with the concern of mortgage has been shown below.
$695.67, $250,441.20, $783.93, $235179, and $15262.2.
Using the formula for the monthly payment of a mortgage:
[tex]P = L[c(1 + c)^n]/[(1 + c)^n - 1][/tex]
Here P is the monthly payment, L is the loan amount, c is the monthly interest rate, and n is the total number of payments (in this case, 30 years = 360 months).
Plugging in the values given:
L = 160000
c = 0.033/12 (monthly interest rate)
n = 360
P = 695.67
So the monthly payment is $695.67.
To find out how much will be paid in total over 30 years, we can multiply the monthly payment by the total number of payments:
Total payments = P * n = $695.67 * 360 = $250,441.20
So the total amount paid to the bank for the home over 30 years is $250,441.20.
To calculate the new monthly payment for a 25-year loan, we can use the same formula but with n = 25*12 = 300 months:
P = 160000[(0.033/12)(1 + (0.033/12))^300]/[(1 + (0.033/12))^300 - 1]
P = $783.93
So the new monthly payment for a 25-year loan is $783.93.
The total amount paid over 25 years would be:
Total payments = P * n = $783.93 * 300 = $235179
So the total amount paid to the bank for the home over 25 years is $235179.
The amount saved by reducing the time of the mortgage loan is the difference between the total amount paid for the 30-year loan and the total amount paid for the 25-year loan:
Savings = $250,441.20 - $235179 = $15262.2
So the amount saved by reducing the time of the mortgage loan is $15262.2.

An earthquake in Gansu, China, on December 16, 1920, measured 8.6 on the Richter scale and killed 100 000 people. An earthquake that usually causes no damage measures 4 on the Richter scale. Compare the intensities of the two earthquakes. (THE ANSWER IS 40000).
The intensity of the Gansu earthquake was approximately 39,811 times greater than that of an earthquake measuring 4 on the Richter scale, which typically causes no damage.
Let's compare the intensities of the two earthquakes using the Richter scale.
Step 1: Understand that the Richter scale is logarithmic, which means each whole number increase represents a tenfold increase in intensity.
Step 2: Determine the difference between the magnitudes of the two earthquakes. The Gansu earthquake measured 8.6, and the earthquake causing no damage measured 4.
8.6 - 4 = 4.6
Step 3: Calculate the intensity ratio between the two earthquakes using the difference in magnitudes. Since each whole number increase represents a tenfold increase in intensity, we need to raise 10 to the power of the difference.
10^4.6 ≈ 39,810.71705535
Step 4: Round the result to a whole number.
39,810.71705535 ≈ 39,811

Step-by-step explanation:
Use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
n = 9, r = 4, p = 0.5

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
To represent a circle with a diameter of 12 units and a center that lies on the y-axis, we can use the standard form of the equation of a circle:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center of the circle, and r is the radius.
If the center of the circle lies on the y-axis, then the x-coordinate of the center is 0. Also, since the diameter is 12 units, the radius is 6 units.
Using these values, we can eliminate the equations that do not meet these conditions:
- x2 + (y – 3)2 = 36: This circle has a center at (0, 3), which is not on the y-axis.
- x2 + (y – 5)2 = 6: This circle has a center at (0, 5), which is not on the y-axis.
- (x – 4)² + y² = 36: This circle has a center at (4, 0), which is not on the y-axis.
- (x + 6)² + y² = 144: This circle has a center at (-6, 0), which is not on the y-axis.
- x2 + (y + 8)2 = 36: This circle has a center at (0, -8), which is on the y-axis.
Therefore, the two equations that represent circles with a diameter of 12 units and a center that lies on the y-axis are:
- x2 + (y + 8)2 = 36
- x2 + (y - 8)2 = 36
Note that the second equation is also valid, since the center of the circle can also be located at (0, -8).

"Divide out a common factor of x - 7." The limit of the given expression is 1/6.
Multiply by (√(x + 2) + 3)/(√(x + 2) + 3):
This statement is not correct.
We generally multiply by the conjugate of the expression to eliminate square roots, but in this case, multiplying by (√(x + 2) + 3)/(√(x + 2) + 3) does not help simplify the expression.
Get x - 1 in the numerator:
This statement is not correct. The expression does not involve x - 1 in the numerator.
Get (x - 7)(√(x + 2) - 3) in the denominator:
This statement is not correct. We want to simplify the expression, not introduce a more complex denominator.
Divide out a common factor of x - 7:
This statement is correct. By factoring out (x - 7) from both the numerator and denominator, we can cancel out the common factor.
Calculate the limit as 1/6:
This statement is not correct. We need to perform further simplification to determine the limit.
After canceling out the common factor of x - 7, the simplified expression becomes:
lim x -> 7 (√(x + 2) - 3)/(x - 7) = lim x -> 7 1/(√(x + 2) + 3)
To find the limit, we substitute the value x = 7 into the simplified expression:
lim x -> 7 1/(√(7 + 2) + 3) = 1/(√(9) + 3) = 1/(3 + 3) = 1/6

simplify 2/3 (3x -2) – ¾ (2x -2)
Answer:
Sure, here are the steps on how to simplify 2/3 (3x -2) – ¾ (2x -2):
Multiply the factors in the numerator and denominator of each fraction.
2/3 (3x -2) = (2)(3x -2) / (3)(3) = 6x - 4 / 9
¾ (2x -2) = (3/4)(2x -2) / (3) = 3x - 6 / 12
Subtract the numerators of the two expressions.
6x - 4 / 9 - 3x - 6 / 12 = (6x - 4 - 3x - 6) / (9 * 12) = 3x - 10 / 108
Simplify the fraction by dividing the numerator and denominator by 3.
3x - 10 / 108 = (3x - 10) / (3 * 36) = x - 10 / 36
Therefore, the simplified expression is x - 10 / 36.

a = 6876-6360 / 480-400
a = 516 / 80
a = 6.45
x' = ∑x/n
x' = 20/6 = 10/3
y' = ∑y/n
y' = 318/6 = 53
b = y' - ax'
b = 53 - 6.45×(10/3)
b = 53 - 21.5
b = 31.5
ŷ = ax + b
ŷ= 6.45x + 31.5
Thus, the equation of the regression line for the given data is
ŷ= 6.45x + 31.5.
(a) x=3 hours
ŷ= 6.45(3) + 31.5 = 50.85
(b) x=4.5 hours
ŷ= 6.45(4.5) + 31.5 = 60.525
(c) x=13 hours
ŷ= 6.45(13) + 31.5 = 115.35
(d) x=1.5 hours
ŷ= 6.45(1.5) + 31.5 = 41.175
