Using the future value formula, it is found that:
a) You will have $301,355 in the account after 30 years.
b) You will have put $108,000 in the account.
c) You will have earned $193,355 in interest.
What is the future value formula?The future value formula is given by:
[tex]V(n) = P\left[\frac{(1 + r)^n - 1}{r}\right][/tex]
In which the parameters are described as follows:
P is the payment.n is the number of payments.r is the interest rate.Considering the $300 deposits, the interest rate of 6% and the monthly compoundings for 30 years, the values of the parameters are given as follows:
P = 300, r = 0.06/12 = 0.005, n = 12 x 30 = 360.
Hence the balance of the account after 30 years will be given by:
[tex]V(30) = 300\left[\frac{(1.005)^{360} - 1}{0.005}\right][/tex]
V(30) = $301,355.
The amount placed into the account is given by:
360 x 300 = $108,000.
The remaining amount is earned in interest, hence:
301355 - 108000 = $193,355.

Polynomial equation
Using the Factor Theorem, the polynomial function with the desired characteristics is given by:
f(x) = -x(x² + 9)(x - 1)(x - 2).
Factor TheoremThe Factor Theorem states that a polynomial function with roots(also called zeros) [tex]x_1, x_2, \codts, x_n[/tex] is given by the rule presented as follows.
[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient of the polynomial, determining if it is positive(a positive) or negative(a negative), determining the end behavior of the function.
For this function, we have:
Two complex roots, hence a factor of (x² + 9).A root at x = 0, hence f(x) = ax(x² + 9).The two other roots are free, hence I am going to attribute x = 1 and x = 2, hence the equation is:
f(x) = ax(x² + 9)(x - 1)(x - 2).
The end behavior is that the function increases to the left and decays to the right, meaning that the leading coefficient is negative, hence a possible function is given by:
f(x) = -x(x² + 9)(x - 1)(x - 2).

Tracy's Termite Control has a net worth of $750,000.
The assets total $980,235.
Recall that the assets are the sum of liabilities and equity.
[tex]Assets=Liabilities+Equity[/tex]For the given case,
Assets = $980,235
Equity = $750,000
Let us substitute these values into the above formula and solve for liabilities

Based on statistics from a worldwide health organization, in 2005 there were22.6 million people worldwide living with a certain disease, and 1.9 million deaths from the disease. By 2015,the number of people living with the disease had grown to 38.9 million deaths were reported. Find the percent change for each statistic, and write any conclusion you can draw.
Percent change of people living with the disease = 72.1%
Percent change of number of death = 5.2%
Explanation:The Number of people living with the disease increased from 22.6 million in 2005 to 38.9 million in 2015
To get the percentage, we will apply the formula:
[tex]percent\text{ change = }\frac{New\text{ value - Old value}}{Old\text{ value}}\times\text{ 100\%}[/tex][tex]\begin{gathered} new\text{ value = 38.9 million, old value = 22.6 million} \\ percent\text{ change = }\frac{38.9\text{ - 22.6}}{22.6}\text{ }\times100 \\ percent\text{ change = 0.721 }\times\text{ 100\% = 72.1\%} \end{gathered}[/tex]The number of death increased from 1.9 million to 2 million from 2005 to 2015:
[tex]\begin{gathered} new\text{ value = 2 million, old value = 1.9 million} \\ The\text{ percent change = }\frac{2-1.9}{1.9}\times100\text{ \%} \\ The\text{ percent change = 0.052 }\times\text{ 100\% = 5.2\%} \end{gathered}[/tex]Conclusion:
The number of people living with the disease increased drastically within 10 years.
But the percent change in the number of death isn't as high as the number of people living with the disease. It means the disease is highly infectious but has a low death rate

there are infintely many solutions. The solution set is {(x, y)| x = 7y - 9} or {(x, y)| 2x - 14y = -18 (option B)
Explanation:Given:
x = 7y - 9 . . .(1)
2x - 14y = -18 . . . (2)
To find:
the solution of the system of equations
To determine the value of x and y, we will apply the substitution method:
we will substitute for x in equation (2):
2(7y - 9) - 14y = -18
2(7y) + 2(-9) - 14y = -18
14y - 18 - 14y = -18
14y - 14y - 18 = -18
0 - 18 = -18
-18 = -18
The left-hand side of the equation is equal to the right side of the equation.
when this happens, it is called infinitely many solutions.
Hence, there are infintely many solutions. The solution set is {(x, y)| x = 7y - 9} or {(x, y)| 2x - 14y = -18 (option B)

The solution to the given inequality in interval notation is: -6 ≤ v ≤ 3
How to solve the given inequality?In this exercise, you're required to determine all the values of v that simultaneously satisfy given inequality. First of all, we would have to eliminate the fraction on the left-hand side of the inequality by adding using an appropriate lowest common denominator of 3 as follows:
(2 × |4v + 6|)/3 - 2/1 ≤ 10
[(2 × |4v + 6|) - (3)2]/3 ≤ 10
[(2 × |4v + 6|) - 6]/3 ≤ 10
Cross-multiplying, we have:
(2 × |4v + 6|) - 6 ≤ 10 × 3
(2 × |4v + 6|) - 6 ≤ 30
Adding 6 to both sides, we have:
(2 × |4v + 6|) - 6 + 6 ≤ 30 + 6
(2 × |4v + 6|) ≤ 36
Dividing both sides by 2, we have:
(2 × |4v + 6|)/2 ≤ 36/2
|4v + 6| ≤ 18
Evaluating the absolute value function, we have:
4v + 6 ≤ ±18
For the positive interval, we have:
4v ≤ 18 - 6
4v ≤ 12
v ≤ 12/4
v ≤ 3.
For the negative interval, we have:
4v ≥ -18 - 6
4v ≥ -24
v ≥ -24/4
v ≥ -6
Lastly, we would express the solution as an interval notation as follows:
-6 ≤ v ≤ 3

A car rental agency charges a fixed fee plus a daily rate. The function f (x) = 30x + 10 expresses the total cost of renting a car for x days. Suppose the agency doubles the fixed fee and increases the daily rate by $5. Which function represents these changes? A. f(x) = 60 (x + 5) + 10 B.f(x) = 60x + 15 C. f(x) = 30 (x + 5) + 20 D. f (x) = 35x + 20
In the given equation:
f(x) = 30x+ 10, where x is the number of days
We can see that at the beggining, when x = 0, then f (0) = 30 · 0+ 10 = 10
Then, renting a car costs at least $10, so $10 is the fixed fee
Each day that passes $30 is being multiplicated, then it cost $300 per day.
Then, the equation is expressed by
f(x)= daily rate · x + fixed fee
If the agency doubles the fixed fee, it would be that 2 · $10 = $20
If the agency increases the daily rate by $5, in addition, then $30 + $5 = $35 woul be the cost each day.
Then, with these new costs we reaplce our equation

What is the equation of the
line that goes through
(-1, 3) and is perpendicular
to y = 4x - 7?
Answer:
Step-by-step explanation:Perpendicular lines have a slope that is the negative reciprocal of the given line.
For example, if a given line has the slope 3/2, the the perpendicular line would have the slope -2/3.
For the given line: y = 4x - 7, the perpendicular line would have a slope of -1/4
There isn't enough info in the question to determine the y-intercept. Literally, any y-intercept could work and the line would still be perpendicular. Is the line supposed to pass through a certain point?
Your answer would be something like: y = -1/4 x + b
b is the y-intercept...if your question paper is multiple choice, choose the answer with the slope of -1/4. If it's supposed to pass through a certain point (x,y) replace x and y with the values in that point and solve for b to get the y-intercept.

distance = 2 1/4 mi = 2.25 mi
time = 3/4 h = 0.75 h
speed = 2.25 mi/0.75 h = 3 mi/h
next, for the distance traveled in 2 1/2 hours, use:
distance = speed x time
time = 21/2 h = 2.5 h
distance = (3 mi/h) x (2.5 h)
distance = 7.5 mi =7 1/2 mi
