1. Devon is young and has just graduated college with her associate's degree. She plans to start saving money for retirement as soon as she starts her new job. By taking 10% of her monthly gross income, Devon is able to contribute (a) $ $587 each month to a retirement plan. The account is expected to earn interest with an APR of 5.25% compounded monthly. Round answers to two decimal places. How much money will be in Devon's retirement account if she continues to make the same monthly investment for 40 years
Using the future value formula, it is found that $546,148,903,191,724.25 will be in Devon's account.
What is the future value formula?It is given by:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
In which:
P is the payment.n is the number of payments.r is the interest rate.In this problem, the parameters are as follows: P = 587, r = 0.0525, n = 40 x 12 = 480.
Hence:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
[tex]V(480) = 587\left[\frac{(1 + 0.0525)^{480-1}}{0.0525}\right][/tex]
[tex]V(480) = 546,148,903,191,724.25[/tex]
$546,148,903,191,724.25 will be in Devon's account.

Answer:
-1080.
Step-by-step explanation:
I take it that k = -3, if so:-
x = -3yz

a 12. A bicycle wheel has a radius of 40 cm. How many times does it revolve during a journey of 10 km? Give your answer to the nearest 100. [For T, use either your calculator value or 3.142.
The bicycle wheel revolving is a illustration of circumference
The bicycle wheel revolves 4000 times
How to determine the number of times?The given parameters are:
Radius (r) = 40 cm
Distance =10 km
Start by calculating the circumference of the wheel
[tex]C =2\pi r[/tex]
This gives
[tex]C =2 * 3.142 * 40[/tex]
[tex]C =251.36[/tex]
The number of times to cover a distance of 10 km is then calculated as:
[tex]n =\frac{10km}{251.36cm}[/tex]
Evaluate the quotient
[tex]n =3978.35773[/tex]
Approximate
[tex]n =4000[/tex]

Find the equation of the line which passes through (-2,1) and which is perpendicular
to the line 2x - 4y = -8. State the answer in slope-intercept form and graph.
-
A line that is perpendicular to a line with slope m has slope -1/m which is the opposite reciprocal of the original slope.
In this case the original line in standard form is
2x-4y=-8
transform this into slop intercept form
-4y=-2x-8
4y=2x+8
y=(1/2)x+2
The slope of this original line is 1/2 therefore the perpendicular line will have slope -2
y'=2x'+b
then substitute in the order pair (x',y')
1=2(-2)+b
b=5
Therefore equation of line is
y=2x+5
The graph is just following this equation!

all you really need to do is find the common denominator and it'll get you an answer for the numerator.
Answer:
13/15
Step-by-step explanation:
You first need to find the common denominator between both 3 and 5, so you have to find the number that would be the best, which is 15. Then you have to multiply the numerator by how many times you went up for that number, for 2/3 would be times 5, and 1/5 would be times 3. Doing this will get you your answer, 13/15.

System of Linear EquationsSystem of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.
For solving this equation, firstly, rewrite the information given:
[tex]\frac{p-5}{q-5}=\frac{9}{1} \;(1)\\ \\\frac{p+20}{q+20}=\frac{7}{3} \;(2)[/tex]
From equation 1, you have:
[tex]p-5=9q-45\\ \\ p=9q-40[/tex]
And from equation 2, you have:
[tex]3*(p+20)=7*(q+20)\\ \\ 3p+60=7q+140\\ \\[/tex]
Now, substitute p=9q-40 in 3p+60=7q+140
[tex]3p+60=7q+140\\ \\3*(9q-40)=7q+140\\ \\ 27q-120=7q+140\\ \\ 20q=20\\ \\ q=10[/tex]
If q=10 for p=9q-40, you will have:
[tex]p=9q-40\\ \\ p=9*10-40\\ \\ p=90-40\\ \\ p=50[/tex]
Therefore, the ratio [tex]\frac{p}{9}[/tex] is equal to [tex]\frac{50}{9}[/tex].
