What is the present value of ​$3,000 per year for 9 years discounted back to the present at 10 ​percent?
Studentka2010 [4]

Answer:

$17,277.07

Step-by-step explanation:

Present value of annuity is the present worth of cash flow that is to be received in the future, if future value is known, rate of interest is r and time is n then PV of annuity is

PV of annuity = \frac{P[1-(1+r)^{-n}]}{r}

                      = \frac{3000[1-(1+0.10)^{-9}]}{0.10}

                      = \frac{3000[1-(1.10)^{-9}]}{0.10}

                      = \frac{3000[1-0.4240976184]}{0.10}

                      = \frac{3000(0.5759023816)}{0.10}

                      = \frac{1,727.7071448}{0.10}

                      = 17,277.071448 ≈ $17,277.07

Find the slope and the y-intercept of the equation 4x + 5y = -9
lutik1710 [3]

Answer:

In your equation 4x+5y=-9, you've got to but your equation in slope intercept form which is y=mx+b.

First we need to get the y by itself.

Subtract 4x from each side to get:

5y=-4x-9

Next we want to divide both sides by 5.

y=-4/5x-9/5

Your slope is m which in our case -4/5.

Then our y-intercept is b or -9/5.

Your answer would then be C. slope=-4/5 and y-intercept=-9/5.

Hope this helps ;)

A group incoming first-year students at Major University were surveyed in order to determine the factors that influenced their d
Ray Of Light [21]

Answer:

Step-by-step explanation:

This is a problem of SETS.

Start by listing out important data:

1. Total that said F = 55

2. Total that said P = 51

3. Total that said O = 61

4. F only = 9

5. F ∩ P ∩ O = 26 [NOTE: If you were to draw a Venn Diagram, 26 would be in the innermost circle because it comprises all three categories]

6. F ∩ P = 31

7. P only = 8

8. Students that said none of the 3 reasons = 4

QUESTIONS

1. How many said O and P? In other words, find the intersect of O and P. Find O ∩ P

2. How many said either F or O? [Answer to be gotten using a venn diagram] Find F ∪ P which translates to "F union P"

3. How many said F without saying P? [Answer to be gotten from the venn diagram as well]

4. How many students in total were surveyed? [HINT: Remember to include the 4 students that had none of the three options]

A school has two computer labs Each lap has 30 computers a total of six computers in the school or not working which expression
Eddi Din [679]

Answer:

Step-by-step explanation:

A school has two computer labs and each lan has 30 computers. This means that the total number of computers is the sum of the number of computers in each lab

Total number of computers = 30+30 = 60

A total of six computers in the school or not working.

The expression that can be used to find the number of working computers in the school will be

Let the number of computers that are working be x

the number of computers that are working is total number of computers minus the number of computers that are not working be

The expression that can be used to find the number of working computers in the school will be

x = 60 - 6

x = 54
