To save for a down payment on a home, suppose you decide to invest in an annuity that pays 7.0% annual interest,
compounded annually. If you contribute $8,000 every year for 5 years, how much interest would you earn during the
5 years? Enter your answer, rounded to the nearest cent, without the dollar sign or comma ($21,678.1235 should be
entered as 21678.12.)
Answers
If you contribute $8,000 every year for 5 years, the interest would you would earn during the 5 years is:6005.91
What is future value of annuity?
The future value of the annuity means the future worth of 5 annual contributions of $8000 every year, based on the fact that the deposits would earn 7.0% interest rate every year, in short, the worth of the savings in 5 years can be determined using the future value of an ordinary annuity as shown below:
FV=PMT*(1+r)^N-1/r
FV=accumulate balance after 5 years=unknown
PMT=annual savings=$8,000
r=interest rate per year=7.0%
N=number of annual payments over 5 years=5
FV=$8000*(1+7.0%)^5-1/7.0%
FV=$46,005.91
Total deposits in 5 years=$8000*5=$40,000
Interest =FV-total deposits
interest=$46,005.91-$40,000
interest=$6,005.91

The triangle shown has an area of 32.5 square centimeters. Find the measure of the base (segment XY).
Answers
Answer:
XY = 13 cm
Step-by-step explanation:
Area of a triangle formula:
area = base × height / 2
a = bh / 2
Plug numbers into equation:
32.5 = b × 5 / 2
Multiply both sides by 2 to isolate the variable
65 = b × 5
Divide both sides by 5 to isolate the variable
13 = b
Check your work:
32.5 = 13 × 5 / 2
32.5 = 65 / 2
32.5 = 32.5

for the function f(x) = 4x+2, evaluate and simplify the difference quotient
Answers
The difference quotient of the function f(x) = 4x + 2 is 4.
What is a function?Functions were originally the idealization of how a varying quantity depends on another quantity.
The given function is,
f(x) = 4x + 2
For a given function f(x), we define the difference quotient as:
[tex]\frac{f(x+ h)-f(x)}{h}[/tex]
Thus, for the given function, difference quotient is given as,
[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4(x+h)+2-(4x+2)}{h}[/tex]
expanding the brackets we get,
[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4x+4h+2-4x-2}{h}[/tex]
Solving we get,
⇒ [tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4h}{h}[/tex]
Thus,we get
⇒ [tex]\frac{f(x+ h)-f(x)}{h}[/tex] = 4
Thus, the difference quotient of the function f(x) = 4x + 2 is 4.

You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $50,000, and the rate is 9.5% using ordinary interest.
You currently have some excess cash: $35,000. Due to situations beyond your control, you, as the owner, must make an immediate business decision now to pursue only one of these two choices:
1) sending all of the $35,000 to Citizens Bank as a partial payment on your loan, or
2) using the $35,000 to purchase serving supplies such as food containers, cups, and plastic dinnerware for your inventory. This is the last day to take advantage of the opportunity to save some money due to a special discount price that is "10% off" the normal cost of $35,000 for these items.
Consider these calculations:
(a)
How much interest (in $) will you save on this loan if you make the partial payment and don't purchase the additional serving supplies? (Round your answer to two decimal places.)
$
Incorrect: Your answer is incorrect.
(b)
How much money (in $) will you save if you purchase the serving supplies with the discount and don't make a partial payment on the loan? (Round your answer to two decimal places.)
$
(c)
How much (in $) will you save by purchasing the discounted serving supplies rather than making the partial payment? (Hint: Find the difference between the savings on the supplies found in part (b) and the savings on the loan interest found in part (a). Round your answer to two decimal places.)
$
(d)
What other factors should you consider before making this decision?
Answers
The amount saved by repaying the loan early is $831.25
The amount of discount received by purchasing supplies is $3,500
The net amount saved by purchasing supplies rather than repaying loan is $2,668.75
What is ordinary interest?
Ordinary interest is the interest computation that is based on 360-day a year count rather than 365-day year count, hence, in determining the amount saved by paying $35,000 out of the amount due to Citizens Bank, we time-apportion the interest for 90 days with respect to 360 days not 365 days.
Amount saved in interest=$35,000*9.5%*90/360
Amount saved in interest=$831.25
Using the $35,000 to purchase serving supplies, 10% discount is given off the normal cost of $35,000
Amount saved with discount=10%*$35,000
Amount saved with discount=$3,500
The difference between discount on supplies and interest saved=$3,500-$831.25
The difference between discount on supplies and interest saved=$ 2,668.75
The other factors to consider before making the final decisions include, the fact the loan is more important than the supplies because the loan relates to the firm's financing rather than operational needs of supplies
Secondly, the amount saved in interest may be more if another loan of $35,000 can be borrowed elsewhere with significant lower interest rates

regular rate and for 5 hours at a time-and-a-half overtime rate. Find Drake's gross pay for week?
Answers
Answer:First, determine the total number of hours worked by multiplying the hours per week by the number of weeks in a year (52). Next, divide this number from the annual salary.if an employee has a salary of $50,000 and works 40 hours per week, the hourly rate is $50,000/2,080 (40 x 52) = $24.04.
Step-by-step explanation:
Divide the gross pay by the wage hours worked. For example, if your records show that the employee was paid $4,000 for the total month, divide 4,000 by 172 to reach $23.26. This is an accurate representation of an hourly rate for that employee's monthly work.

If there is only one solution, the given lines are intersecting; if no solution is possible, the given equations have been of parallel lines. If there are an infinite number of solutions, it means that given equations form coincident lines.For the given question.
Let 'x' be the number of matinee showings.
Let 'y' be the number of prime-time showings.
Then. the total ticket sold are 1,411.
Thus, x + y = 1,411.
or, x = 1,411 - y
The cost of one matinee showings is $9.
The cost of one prime-time showings is $13.50.
Now, the total cost earned is $17,149.50.
So,
9x + 13.5y = 17,149.50
Put the value of the 'x' in the above equation.
9(1,411 - y) + 13.5y = 17,149.50
Simplifying;
12699 - 9y + 13.5y = 17,149.50
4.5y = 4450.5
y = 989.
Calculate x;
x = 1,411 - 989
x = 422
Therefore, the number of matinee and prime-time movie tickets were sold that day are 422 and 989.

The equation of the line with a slope of 2/7 that passes through the point (3, -4) is:
y = (2/7)*x - 34/7
How to write the linear equation?Here we know that the linear equation has a slope of 2/7, so we can start by writing it as:
y = (2/7)*x + b
Now we need to find the value of b, which is the y-intercept.
To find the value of b, we can use the values on the given point, which is (3, -4), This means that when the value of x is 3, the value of y is -4, then we can replace that in the above linear equation, so we will get:
-4 = (2/7)*3 + b
-4 - 6/7 = b
-28/7 - 6/7 = b
-34/7 = b

The given scenario, "A school administrator gets the alphabetical list of students and chooses every third one to survey", is Systematic Sampling.
In the question, we are asked to identify the type of sampling used in the scenario: "a school administrator gets the alphabetical list of students and chooses every third one to survey", among cluster, convenience, stratified, and systematic.
First, we will understand all these types of sampling:-
Cluster Sampling: By segmenting the population into clusters, usually, geographically, cluster sampling is performed. These units are referred to as blocks or clusters. The clusters are chosen at random, and each component in the chosen clusters is used.Convenience Sampling: Convenience sampling is the most straightforward method, but it should never be used. Convenient data are utilized in convenience sampling. These are the first individuals the surveyor encounters.Stratified Sampling: The population is also divided into groups known as strata via stratified sampling. This time, though, it is based on a characteristic rather than a location.Systematic Sampling: In systematic sampling, the elements are "counted off" from the list. Every kth element is thus taken. Comparable to having everyone in a line and counting off "1,2,3,4; 1,2,3,4; etc." All those numbered 4 would be used once the list had been completed.In the given scenario, the school administrator is getting the list of students in alphabetical order, similar to taking everyone in a line and counting off "1,2,3,4; 1,2,3,4; etc. And then he is choosing every third student, similar to choosing all those numbered 4.
