Answers

Answer 1

Answer:

A. (-3,0)

Step-by-step explanation: you have to set the equation y to zero and than calculate the x

--> (x + 2)(x2 + 4x+3) = 0

--> (x+2) = 0 and (x2 +4x + 3) =0

--> X = -2 and        D= (4² - 4*2*3) = 4

                                      X = (-4 + [tex]\sqrt{4}[/tex]) / 2 of  X = (-4 + [tex]\sqrt{4}[/tex]) / 2

                                       x= -1                         x=-3

In 1986 a family member invested$ 100 each month into savings account with an interest rate of 0.25% that didn't change. In 2016 you decided you needed to use that saved up money for a big purchase so you cash the savings account out

Answers

Complete question is;

In 1986, a family member invested $100 each month into a savings account with an interest rate of 0.25% (that didn't change). In 2016, you decided you needed to use that saved up money for a big purchase, so you cash the savings account out.

How much money should be in the account using the FV formula?

Answer:

FV = $107.78

Step-by-step explanation:

We are given;

Present value; PV = 100

Interest rate; r = 0.25% = 0.0025

We are told the PV was in 1986 and In 2016 you decided you needed to use that saved up money .

This is a period of 30 years.

Thus, the number of compounding periods is n = 30

Formula for FV is;

FV = PV(1 + r)ⁿ

FV = 100(1 + 0.0025)^(30)

FV = $107.78

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that a quadratic function given the roots (4,0) and (2, 0). The quadratic equation will be formed as below:-

The two roots of the quadratic equation are 2 and 4 then the two factors will be ( x- 2 ) and ( x - 4).

y = -4(x-2)(x-4)

y = -4x² + 24x - 32.

Therefore, the expression for the quadratic function will be y = -4x² + 24x - 32.

Marc earns $45,000 per year. If he does not work for 2 months in a year, how much money would he earn?

Answers

Answer:

$37500

Step-by-step explanation:

45000 divided by 12 = 3750

3750 is how much he earns each month.

3750x2=7500

7500 is how much he earns in 2 months

45000-7500=37500

Answer:

37,500

Step-by-step explanation:

if he makes 45,000 a year, we need to find out how much he makes per month.

divide 45,00 by 12= 3750 per month

3750 times 2 months= 7500

45,000-7,500= 37,500

Given that Jocelyn saved $60 in 8 weeks, predict the number of weeks it will take Jocelyn to save $90. Include in your explanation any assumptions that must be made in order to make the prediction. Enter your explanation in the space provided.

Answers

number of weeks: w is the x value, and the number of money saved: m  is the y value. First, we need to find out how much she makes in 1 w and because k = y/x, we need to divide 60 by 8, which gives u 7.5, so she saves $7.50 every week Finally, we figure out the number of weeks it takes her to save $90, and to do that, we use the formula x = y/k. Using that formula, we get the expression $90/$7.50 or $90/$7.5. 90/7.50 = 12, so x = 12. It will take her 12 weeks to save $90. In order to check our answer, we can say that we didn't know the number of m she saved, but we do know how many weeks. To find a solution, we use the formula y = kx (the blank between kx means that we are multiplying). Using that formula, we get the equation 12 X 7.50. When we solve this equation, we get 90, and since it is the same answer as the real problem, that means the answer for the real problem is correct. (BTW sorry this is so long)

The probability that a 22-year-old female in the U.S. will die within one year is approximately 0.00044. If an insurance company sells a one-year, $30,000 life insurance policy to such a person for $435, what is the company's expectation? (Round your answer to the nearest dollar.)

Answers

Answer:

The value is  [tex]E(X) = \$ 421.6[/tex]

Step-by-step explanation:

From the question we are told that

The probability that a 22 year  old  female in US will die within one year is    p= 0.00044

The outcome if she dies within one year is that the company losses $30,000

Generally the probability that  a 22 year  old  female in US will live more than one year is

           [tex]q = 1 -p[/tex]

=>        [tex]q = 1 -0.00044[/tex]

=>        [tex]q = 0.99956[/tex]

The outcome if she lives more than one year is that the company gains $435

Generally the  the company's expectation is mathematically represented as

           [tex]E(X) = -30000 * p + 435 * q[/tex]

The negative sign shows that the company is loosing the fund

So  

       [tex]E(X) = -30000 * 0.00044 + 435 * 0.99956[/tex]

=>    [tex]E(X) = \$ 421.6[/tex]
