You have a goal of saving to build up a nest egg of $625,357.24, and you are going to make regular deposits to an account that pays an APR of 7.2% compounded monthly. What monthly deposits are required to reach this goal in 40 years? (Round your answer to the nearest cent.)
The monthly deposit required to save up to $625,357.24 (future value) in 40 years at a 7.2% APR is $225.20.
What is the monthly deposit?The monthly deposits are the periodic savings that the investor must make to achieve future value.
The monthly deposit is compounded at the monthly annual percentage rate (APR).
We can compute the required monthly deposits using an online finance calculator as follows:
N (# of periods) = 480 months (40 years x 12)
I/Y (Interest per year) = 7.2%
PV (Present Value) = $0
FV (Future Value) = $625,357.24
Results:
Monthly Deposits (PMT) = $225.20
Sum of all periodic payments = $108,096 ($225.20 x 480)
Total Interest = $517,261.24
Thus, to save $625,357.24 in 40 years, you need to deposit $225.20 monthly.

The transformation of the graphs is
1st graph is (x,y)→(x-4,y+2)
2nd graph is (x,y)→(x+6,y+0)
Given that,
There are two graphs with 2 triangles in each graph.
We have to find the transformation of the graphs.
Take the 1st graph,
We have 2 triangles ABC and A'B'C'.
The points are,
A=(0,0), B=(3,-4) and C=(-1,-2)
A'=(-4,2), B'=(1,-2) and C'=(-5,0)
We get the transformation as
(x,y)→(x-4,y+2)
Check the A and A' points
The A terms goes left for 4 times to A' so we take x-4 and the A terms goes up for 2 times to A' so we take y+2.
Similarly,
The B terms goes left for 4 times to B' so we take x-4 and the B terms goes up for 2 times to B' so we take y+2.
Similarly,
The C terms goes left for 4 times to C' so we take x-4 and the C terms goes up for 2 times to C' so we take y+2.
Now the 2nd graph,
We have triangle FCP and F'C'P'
The points are,
F=(-5,5), C=(-2,5) and P=(-3,0)
F'=(1,5), C'=(4,5) and P'=(3,0)
We get the transformation as
(x,y)→(x+6,y+0)
Check the F and F' points
The F terms goes right for 6 times to F' so we take x+6 and the F terms remain same so we take y+0
Similarly,
The C terms goes right for 6 times to C' so we take x+6 and the C terms remain same so we take y+0
Similarly,
The P terms goes right for 6 times to P' so we take x+6 and the P terms remain same so we take y+0

The height of Alexander's triangle in inches is 4 inches
How to find the scale of the mapThe scale of the map is gotten by comparing the first dimensions Alexander drew
He made 10 inches to represent 3000 feet, this is equivalent to 1 inch to 300 feet hence the scale is 1 inch : 300 feet
Using the scale, a height of 1200 feet would be
1 inch = 300 feet
? inch = 1200 feet

(a) Find the probability that exactly three of them fail the test.
(b) Find the probability that fewer than three of them fail the test.
What is Binomial Distribution?
The probability of success is said to follow a binomial distribution when many similar and independent Bernoulli trials are conducted. The likelihood of success and the quantity of tries are its dimensions. For every trial, the chance of success is the same.
State emission test failure probability is 0.05.
12 vehicles total are present.
Let's look at failing the test as a victory. If success is represented by p, then p = 0.05.
Considering that n represents the number of cars, n equals 12.
Let X represent how many vehicles fail the test.
So, X ∼ Bin (8,0.05)
P(X=x)= [tex]^{n}C_{x}p^{x}(1-p)^{n-x}[/tex]
= [tex]^{12}C_{x}0.05^{x}(0.95)^{12-x}[/tex]
a) Probability that exactly 3 automobiles fail the test is given by,
P(X=3)= [tex]^{12}C_{3}0.05^{3}(0.95)^{12-3}[/tex]
=0.01733
So, the probability that exactly 3 automobiles fail the test is 0.01733.
b) Probability that fewer of them than 3 fail the test is given by,
P(X<3)= P(X≤2)
= P(X=0)+P(X=1)+P(X=2)
= [tex]^{12}C_{0}(0.05)^{0}(0.95)^{12}[/tex] + [tex]^{12}C_{1}(0.05)^{1}(0.95)^{11}[/tex]+[tex]^{12}C_{2}(0.05)^{2}(0.95)^{10}[/tex]

Equation of line will be y = x/3 - 2
A line's equation can be written in many forms in which one is slope-intercept form.
Equation in slope-intercept form is written as y = mx + c where
m = slope
c = y intercept
Slope shows the steepness of the line. It can be given by change in y axis by change in x axis.
y intercept is the point where the line cuts the y axis that is x = 0 at this point.
Points given to us are (6 , 0) and (9 , 1)
slope = [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
m = (1 - 0) / (9-6)
m = 1/3
For c put values of either point in the equation as they both are on the line so they both will satisfy the equation.
y = mx + c
0 = (1/3)*6 + c
0 = 2 + c
c = -2

Answer:

Step-by-step explanation:
y = 2x + 6
Perpendicular: y = (-1/2)x + 6
m = (-1/2); (2, -5)
(x₁, y₁)
y - y₁ = m(x - x₁)
y - (-5) = (-1/2)(x - 2)
y + 5 = (-1/2)x + 1
-5 -5
----------------------------
y = (-1/2)x - 4
I hope this helps!
Step-by-step explanation:
the slope-intercept form is
y = ax + b
"a" being the slope, "b" being the y-intercept (the y- value when x = 0).
the slope is the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.
a perpendicular slope simply turns the original slope upside-down with x and y, and it flips the sign.
the slope of the origins line is 2 = 2/1.
the perpendicular slope is -1/2.
so, the equation looks like
y = -1/2 x + b
to get b we use the point coordinates :
-5 = -1/2 × 2 + b = -1 + b
-4 = b
so, the full equation is
y = -1/2 x - 4

Which values are in the solution set of the compound inequality? Select two options. 4(x + 3) ≤ 0 or x+1>3 –6 –3 0 3 8
The values -3 , -6 , 3 , 8 are in the solution set of the compound inequality 4(x + 3) ≤ 0 and x + 1 > 3
Given, a compound inequality
4(x + 3) ≤ 0 and x + 1 > 3
Now, on solving the first inequality, we get
4(x + 3) ≤ 0
4x + 12 ≤ 0
On subtracting both the sides by 12, we get
4x + 12 - 12 ≤ 0 - 12
4x ≤ -12
On dividing both the sides by 4, we get
4x/4 ≤ -12/4
x ≤ -3
So, the solution set of the 4(x + 3) ≤ 0 inequality be, x ≤ -3 i.e. all the real numbers less than -3.
Now, on solving the second inequality, we get
x + 1 > 3
On subtracting both the sides by 1, we get
x + 1 - 1 > 3 - 1
x > 2
So, the solution set of the x + 1 > 3 inequality be, x > 2 i.e. all the real number greater than 2.
Now, the values in the solution set of the compound inequality
4(x + 3) ≤ 0 and x + 1 > 3 be,
x ≤ -3 and x > 2.
As, we can see -3 , -6 , 3 , 8 are satisfying the condition.
Hence, -3 , -6 , 3 , 8 are the values in the solution set of the compound inequality 4(x + 3) ≤ 0 and x + 1 > 3.
