The value of a painting can be predicted by the expression 120(1.08)t, where t is the number of years since 2014.
What does the value 120 represent?

1. the predicted value of the painting in 2014

2. the predicted change in the value of the painting each year

3. the predicted percent change in the value of the painting each year

4. the number of years for which the value of the painting is predicted to continue changing

Answers

Answer:

1. the predicted value of the painting in 2014

Step-by-step explanation:

In the expression, 120 represents the initial value of the painting.

In expression [tex]120(1.08)^t[/tex], t is the number of years since 2014, and 120 represents the predicted value of the painting in 2014.

Find the area and perimeter of a square that has a side length of 4. Remember area is a length times width and perimeter is when you add all the sides together.

Answers

Answer:

Area= 16

Perimeter= 16

Answer:

A = l*w

P = 2l + 2w

A = 4*4 = 16

A = area

l = length

l = 4

w = width

w = 4

The area is equal to 16.

P = 2*4 + 2*4 = 16

P = perimeter

2l = 2*length

2l = 2*4

2w = 2*width

2w = 2*4

The perimeter is equal to 16.

It can be concluded both are equal to each other.

QUESTION 9 of 10: Your insurance company bills you $687.89 every 6 months for your premium payments. You decide to pay per month.
What is the monthly premium?
O a) $114,65
b) $120.66
c) $144.78
d) $687.89

Answers

Answer: $114.65

Step-by-step explanation:

From the question, we are told that a insurance company bills a customer $687.89 every 6 months for your premium payments.

Since the customer has decided to be paying per month, we divide the amount paid for the 6 months which is $687.89 divided by 6. This will be:

= $687.89/6

= $114.65

The person will pay $114.65 monthly

Answer:

114.65

An amount was invested at

per quarter. What value of

will ensure that accumulated

amount at the end of one year is 1.5 times more than amount invested? Correct to 2 decimal

places​

Answers

Answer:

10.67%  per quarter

42.68%  per year

Step-by-step explanation:

The value of r that would be ensure the initial amount gives 1.5 times future value in in one year can be computed using rate  formula  in excel as below:

=rate(nper,pmt,-pv,fv)

nper is 1 year multiplied 4 quarters=4

pmt is the amount invested  periodically and it is zero

Assume that $1000 was invested

FV which is the future value=1.5*$1000=$1,500

PV=$1000

=rate(4,0,-1000,1500)

rate=10.67%

rate per year=10.67% *4

What is: x^2+2x-35? Please help

Answers

Answer:

(x +7)(x - 5)

Step-by-step explanation:

x² + 2x - 35

- 35 = 7*(-5)

2 = 7 + (-5)

x² + 2x - 35 = (x +7)(x - 5)

To expand on the other users answer:
Once you have (X+7)(X-5) you set each term to zero to find the value of x.
So x+7=0 X=-7
And x-5=0 X=5
So your possible values for x are -7 and 5

A local car dealership is trying to sell all of the cars that are on the lot. Currently, there are 525 cars on the lot, and the general manager estimates that they will consistently sell 50 cars per week. Estimate how many weeks it will take for the number of cars on the lot to be less than 75. Write an inequality that can be used to find the number of full weeks, , it will take for the number of cars to be less than 75. Since is the number of full or complete weeks, = 1 means at the end of week 1. Write and solve the inequality

Answers

Answer:

525/50=10.5 it will take 10.5 weeks to get rid of every car we however only need to have below 75 so 525/50w<75

Step-by-step explanation:

First you need to divide 525 by 50 to show how many weeks it will take to sell all the cars. And then it should be one less week than the answer you just reacieved.

Sammy wants to deposit into a 7% annual simple interest account she will also deposit twice as much in a certificate of deposit earning 5% annual simple interest to earn $390 of annual interest how much should she invest in each account?​

Answers

Answer: $2294 should be invested in the simple interest account while $4588 should be invested in the certificate of deposit.

Step-by-step explanation:

Let x represent the amount that he would deposit in the simple interest account.

Let y represent the amount that he would deposit in the certificate of deposit.

she will deposit twice as much in the certificate of deposit. It means that

y = 2x

Interest from the simple interest account would be 7%. This mean that the interest would be 7/100 × x = $0.07x

Interest from the certificate of deposit account would be 5%. This mean that the interest would be 5/100 × y = $0.05y.

The total interest from both accounts would be $390. It means that

0.07x + 0.05y = 390- - - - - - - - - - 1

Substituting y = 2x into equation 1, it becomes

0.07x + 0.05 × 2x = 390

0.07x + 0.1x = 390

0.17x = 390

x = 390/0.17 = $2294

y = 2x = 2 × 2294

y = 4588

The slope of the line whose equation is 5x - 3y = 4 is

Answers

Answer:

The slope is 5/3

Step-by-step explanation:

5x - 3y = 4

Solve for y

Subtract 5x from each side

5x-5x - 3y =-5x+ 4

-3y = -5x+4

Divide each side by -3

-3y/-3 = -5x/-3 +4/-3

y = 5/3x -4/3

This is in the form

y =mx+b

The slope is m and the y intercept is b

The slope is 5/3
