Charles, age 45, would like to determine how much life insurance to purchase using the human life value approach. He assumes his average annual earnings will remain at $40,000. Of this amount, $20,912 is available annually for the support of his family. Charles will generate this income for 24 more years and he believes that 5.37 percent is the appropriate interest (discount) rate. What is Charles' human life value? (Round your answer to 2 decimal places)

Answers

Using it's formula, it is found that Charles' human life value is of $26,951.39.

What is the human life value formula?

The human life value formula(HLV) is given by the following multiplication:

HLV = Annual Expenses x Number of Years x Interest Rate.

For this problem, we have that:

$20,912 is available annually for the support of his family, hence the annual expenses are of $20,912.Charles will generate this income for 24 more years, hence the number of years is of 24.As stated in the problem, the interest rate is of 5.37%, hence, as a decimal, is of 0.0537.

Hence, applying the formula, we have that Charles' human life value is found as follows:

HLV = 20912 x 24 x 0.0537

HLV = $26,951.39.

Charles' human life value is of $26,951.39.

The slope of the linear function shown in the graph is of 2, as:

Run = 2.Slope = rise/run = 4/2 = 2.

What is a linear function?

A linear function is modeled according to the following rule:

y = mx + b

In which:

m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis, that is, when x = 0.

For this problem, we want to find the slope given two points of the function, which are (2,4).

For the calculation, we have that:

The rise is the change in y.The run is the change in x.

Hence:

The rise is of 4 - 0 = 4.The run is of 2 - 0 = 2.The slope is of 4/2 = 2.

The vertical position y (in feet) of a rock t seconds after it was dropped from a cliff is given by the formula y equals short dash -16 t squared plus 4 t plus 380. The base of the cliff corresponds to y = 0. After how many seconds will the rock hit the ground at the base of the cliff?

Answers

The seconds that it will take the rock hit the ground at the base of the cliff is 5 seconds

How to calculate the value?

Based on the information given, it should be noted that the expression given is:

y = -16t² + 4t +380

We have to divide through by 4. Therefore,

y = -4t² + t + 95

y = -4t² + 20t - 19t + 95

y = -4t(t - 5) - 19(t - 5)

t - 5 = 0

t = 0 + 5

two investments totaling $28,000 produce annual income of $1435. One investment yields 9% per year, while the other yields 2% per year. How much is invested at each rate

Answers

The investment amount at 9% rate is $12500 and the investment

amount at 2% rate is $15500

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Let x be the amount invested at 9% rate.

And (28000−x) be the amount invested at 2% rate.

The total annual income is $1435

Let us find the amount invested at 9% rate:

x9%+2%(28000−x)=1435

9%+2%(28000−x)=1435

0.09x+0.02(28000−x)=1435

0.09x+560−0.02x=1435

0.09x−0.02x=1435−560

0.07x=875

x=875/0.07

x=12500

Let us find the investment amount at 2% rate:

⇒28000−x

⇒28000−12500

⇒15500

Therefore, the investment amount at 9% rate is $12500 and the investment amount at 2% rate is $15500.

aka (500*12)+(1250*12)+1150+1150+1150+600+600+600

Applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

How to Apply the Linear Pair Theorem?

The linear pair theorem states that when two angles form a linear pair, the sum of both angles of the linear pair would be equal to 180 degrees.

What is the Vertical Angles Theorem?

Two angles that are a vertical pair, have a measure that is equal to each other, based on the vertical angles theorem. That is, they are congruent angles.

m<RQS + m<PQT = 180 degrees [linear pair theorem]

Substitute

(2m + 4)° + (3m + 1)° = 180°

Solve of the value of m

2m + 4 + 3m + 1 = 180

Add like terms together

2m + 3m + 4 + 1 = 180

5m + 5 = 180

5m + 5 - 5 = 180 - 5

5m = 175

5m/5 = 175/5

m = 35

m<PQR = 3m + 1 [vertical angles theorem]

Plug in the value of m

m<PQR = 3(35) + 1

m<PQR = 105 + 1

m<PQR = 106°

m<PQV = 1/2(m<PQR)

m<PQV = 1/2(106)

m<PQV = 53°

Thus, applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

What is the average number of miles she would have to ride each day to meet her goal?

We know that Mayerlin wants to ride her bicycle for 56 miles this week, and she already has ridden 8 miles, so the distance left is:

56mi - 8mi = 48mi

Now, to find the average distance that she needs to ride each day in order to meet her goal, we need to take the quotient between the distance left and the number days that she has left (6 days), then we will get:
