Sam invests a sum of money in a retirement account with a fixed annual interest rate of 7%
compounded quarterly. After 13 years, the balance reaches $19,280.02. What was the amount of
the initial investment? ROUND YOUR ANSWER TO THE NEAREST DOLLAR (do NOT put a dollar
sign $ in your answer)

Answers

Answer:

The initial amount of investment was $7,822

Step-by-step explanation:

The formula for compound interest, including principal sum is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where

A is the future value of the investment/loan, including interestP is the principal investment amount  r is the annual interest rate (decimal)n is the number of times that interest is compounded per unit tt is the time the money is invested or borrowed for

Let us use this rule to solve the question

∵ Sam invests a sum of money in a retirement account with a fixed

   annual interest rate of 7% compounded quarterly

r = 7% = [tex]\frac{7}{100}[/tex] = 0.07

n = 4 ⇒ compounded quarterly

∵ After 13 years, the balance reaches $19,280.02

A = 19,280.02

t = 13

Substitute these values in the rule above to find P

∵ [tex]19,280.02=P(1+\frac{0.07}{4})^{4(13)}[/tex]

∴ [tex]19,280.02=P(1.0175)^{52}[/tex]

→ Divide both sides by [tex](1.0175)^{52}[/tex]

∴ 7,821.99888 = P

→ Round it to the nearest dollar

∴ 7,822 = P

P = $7,822

The initial amount of investment was $7,822.

How do functions and slopes work i dont understand anything work?

Answers

Slope shows both steepness and direction. With positive slope the line moves upward when going from left to right. With negative slope the line moves down when going from left to right. If two linear functions have the same slope they are parallel.

What is the slope of this equation?y= -1/2x −3 Question 2 options: 0 -3 -1/2

Answers

Answer:

-1/2

Step-by-step explanation:

In the equation y=mx+b..

y and x are the coordinates that go into your function

m is the slope

and b is the y intercept

looking at y=-1/2x-3 i can tell that -1/2 is in the place of m which is slope, and -3 is the y intercept.

Mr. Gaines is catering his company picnic. He will pay $18.45 for 3 people to eat the barbecue lunch. At this rate, how many people can Mr. Gaines afford to feed on a budget of $1,850.00

Answers

Answer: 300 people

Step-by-step explanation:

From the question, we are informed that Mr. Gaines is catering his company picnic and he will pay $18.45 for 3 people to eat the barbecue lunch. This means the cost per person will be:

= $18.45/3

= $6.15

For $1850, the number of people that Me Gaines can feed will be:

= $1850/$6.15

= 300 people

Marcus is buying taco shells for a party. There will be 13 adults and 17 children
attending the party. He plans to make 3 tacos for each adult and 1 taco for each child.
There are 8 taco shells in each package. How many packages of taco shells will Marcus
need to buy in order to have enough tacos for the people attending the party?
A 7, because (13 x 3 + 17) + 8 = 7
B 28, because (13 x 17 + 3) = 8 = 28
C 80, because (13 + 17) x 8 = 3 = 80
D 15, because (13 + 17 x 4) + 8 = 15

Answers

Answer:

Tacos for adults: 13*3

Tacos for children: 17*1

Total: 39+17

=56

And in each package there will be 8 tacos

So, 56/8 = 7 = No. of tacos needed.

So the corrrect answer is A 7, because (13 x 3 + 17) + 8 = 7

Which of the following statements is TRUE about parallel lines pq and rs?

a° and c° are alternate interior angles
a° and c° are alternate exterior angles
a° and c° are corresponding angles
a° and c° are vertical angles

Answers

Answer:

a and c are alternate interior angles

For the parallel lines pq and rs a° and c° are alternate interior angles. Option A is correct.

What are parallel lines?

Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.

Here,
When two parallel lines is intersect by a transversal line then the angles made facing the region between the parallel lines are said to be interior angles, And as we know that alternate angles for parallel lines are always equal. So a° and c° are alternate interior angles.

Thus, a° and c° are alternate interior angles.
