Suppose our retirement account pays 9% apr compounded monthly; what size nest egg do we need in order to retire with 25 years that yields to $5,000 per month? Show all work
Answer:
$595,808.11
Step-by-step explanation:
We assume the retirement account is intended to pay out $5000 per month for 25 years. The amortization formula can be used to find the required amount. The monthly payment A based on principal P with interest at annual rate r for t years satisfies the relation ...
A = P(r/12)/(1 -(1 +r/12)^(-rt))
P = A(12/r)(1 -(1 +r/12)^(-rt))
P = 5000(12/0.09)(1 -(1 +.09/12)^-300)
P = $595,808.11
The required nest egg is $595,808.11.

The graph of y=|x−1|+ 7 is reflected across the y-axis and then translated up 1 unit. What is an equation of the transformed graph?
Answer:
y = |-x-1| + 8.
Step-by-step explanation:
A reflection across the y axis gives the equation y = |-x -1| + 7.
Then a translation up 1 unit gives the equation y = |-x-1| + 8.

y = 3 in two variable
Step-by-step explanation:
If Y = 3 is treated as an equation in one variable, then it has a unique solution y= 3. So it is a point on the number line. Given equation Y equal to 3 can be written as 0. x + y = 3, which is a linear equation in two variables x and y.

20 POINTS TO EARN
Answer:
(2,-5)
Step-by-step explanation:
The slope of the line is 3/4. You need to find 2/3 of this, which is quite easy. Since the slope is 3/4, then 2/3 of 3/4 would be 2/4, or 1/2. 2/4 slope of this line brings you to the point (2,-5) which is point B.

Find the percent of increase from 8 to 10 feet
Answer:
25%
Step-by-step explanation:
[tex]percentage \: increase \\= \frac{10 - 8}{8} \times 100 \\ \\ = \frac{2}{8} \times 100 \\ \\ = \frac{1}{4} \times 100 \\ \\ = 25 \%[/tex]
The increase in height from 8 to 10 feet is 25%. To calculate a percentage, divide the value by the total value and multiply the result by 100.
How to calculate percentage?To calculate a percentage, divide the value by the total value and multiply the result by 100. (value/total value)100% is the formula for calculating percentage. Divide the number you want to convert to a percentage by the total. In this case, divide 2 by 5. 2 divided by 5 equals 0.4. Then, multiply 0.4 by 100 to get 40, or 40%.Divide one number by the other and multiply the result by 100 to find the percentage of a number between two numbers. To calculate the percentage, divide the value by the total value and multiply the result by 100.Therefore,
percentage increase
= (10 - 8) / 8 × 100
= 2/8 × 100
= 1/4 × 100
= 25%
Hence, The increase in height from 8 to 10 feet is 25%.

Which equation has a pair of equivalent ratios?
Answer:
Option (3)
Step-by-step explanation:
If the two ratios are equivalent then the value of the ratios will be equal.
[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]
Option (1)
[tex]\frac{11}{12}=\frac{44}{46}[/tex]
Simplified form of the fraction [tex]\frac{44}{46}[/tex] is,
[tex]\frac{44}{46}=\frac{22}{23}\times \frac{2}{2}=\frac{22}{23}[/tex]
Therefore, [tex]\frac{11}{12}=\frac{22}{23}[/tex]
Which is not true,
Therefore, option (1) doesn't show the equivalent ratio.
Option (2)
[tex]\frac{36}{40}=\frac{4}{9}[/tex]
Simplified form of [tex]\frac{36}{40}[/tex] is,
[tex]\frac{36}{40}=\frac{9}{10}\times \frac{4}{4}=\frac{9}{10}[/tex]
Therefore, [tex]\frac{4}{9}= \frac{9}{10}[/tex]
Which is not true.
Therefore, option (2) doesn't show the equivalent ratio.
Option (3)
[tex]\frac{1.5}{3}=\frac{12}{24}[/tex]
Since simplified form of [tex]\frac{1.5}{3}[/tex] is,
[tex]\frac{1.5}{3}=0.5[/tex]
And simplified form of [tex]\frac{12}{24}[/tex] is,
[tex]\frac{12}{24}=0.5[/tex]
Therefore, [tex]\frac{1.5}{3}=\frac{12}{24}=0.5[/tex]
Option (3) shows the equivalent ratios.
Option (4)
[tex]\frac{8}{12}=\frac{4}{24}[/tex]
Since, [tex]\frac{8}{12}=\frac{2}{3}\times \frac{4}{4}=\frac{2}{3}[/tex]
And [tex]\frac{4}{24}=\frac{1}{6}\times \frac{4}{4}=\frac{1}{6}[/tex]
But [tex]\frac{2}{3}\neq \frac{1}{6}[/tex]
Therefore, equation in this option doesn't show the equivalent ratios.

each morning max walks to school. at 8:20, he passes a stoplight that is 2 blocks from home. He reaches the town library at 8:24. At this point, he is 3 blocks from school and halfway there. If Max walks at the same pace all the way to school, at what time does he arrive at school?
Answer:
8:36
Step-by-step explanation:
If he is at his halfway point at 8:24 and it only took him 4 minutes to get one block in than it would take him 12 minutes to get 3 blocks in and if you add 12 more minutes to the time that he's at right now than he would arrive at 8:36.

Name the slope and one point that is on the line
represented by the equation: x = -2
A) m = undefined and point (-2,5)
B) m = 0 and point (-2,4)
C) m = undefined and point (5,-2)
D) = zero and point (5,0)
Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.

A company estimates that 0.7% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $350. If they offer a 2 year extended warranty for $48, what is the company's expected value of each warranty sold?
Answer:
$44.90
Step-by-step explanation:
The resulting value for the company of replacing a failed product is given by the price of the warranty minus the cost of replacement:
F = $47-$300=-$253
This event has a 0.7% chance of happening.
The resulting value for selling extended warranty to a product that does not fail is given by the price of the warranty:
W = $47
This event has a 99.3% chance of happening.
The expected value is:
EV = $44 * 0.993 + ($47-$300) *0.007
EV = $44.90
The expected value for each warranty sold is $44.90.
