Suppose that you borrow ​$11000 for 4 years at 6​% toward the purchase of a car. Find the monthly payments and the total interest for the loan.

Answers

Answer:

The monthly payments ≅ $258.335

The total interest of the loan ≅ $1400.095

Step-by-step explanation:

The rule of the monthly payments is

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

P is the initial amountr is the rate in decimaln is the period in a yeart is the number of years

∵ You borrow ​$11000

∴ P = 11000

∵ It will be for 4 years

∴ t = 4

∵ The rate is 6%

∴ r = 6% = [tex]\frac{6}{100}[/tex] = 0.06

∵ It is a monthly payment

∴ n = 12

→ Substitute these values in the rule above

∴ [tex]M.P=\frac{11000(\frac{0.06}{12})}{1-(1+\frac{0.06}{12})^{-12(4)}}[/tex]

→ Use your calculator to find the answer

∴ M.P = 258.3353195

∴ The monthly payments ≅ $258.335

→ The total interest of the loan is the difference between the total

   of the monthly payments and the initial amount

∴ The total interest of the loan = T.M.P - P

∵ The total of the monthly payments = M.P × t × n

∴ The total of the monthly payments = 258.3353195 × 4 × 12

∴ The total of the monthly payments = $12400.09534

∵ The initial amount P = $11000

∴ The total interest of the loan = 12400.09534 - 11000

∴ The total interest of the loan = 1400.095

∴ The total interest of the loan ≅ $1400.095

A reflection across the x-axis maps the point (4,-5) to the point

Answers

Answer:

(4,5)

Step-by-step explanation:

A reflection is a mirror image of the shape.

A reflection across the x-axis maps point (4,-5) to point (4. 5).

What is reflection?

A reflection is a mirror image of the shape.

After the reflection, every point in a figure is equidistant from each corresponding point in the reflected figure.

We have,

A point = (4, -5)

The point is reflected across the x-axis.

The reflection formula is given as:

Reflection across the x-axis:

(x, y) → (x, -y)

Reflection across the y-axis:

(x, y) → (-x, y)

The point (4, -5) reflected across the x-axis is:

(4, -5) → (4, - (-5)) = (4, 5)

Thus,

A reflection across the x-axis maps point (4,-5) to point (4. 5).

There is a parade coming through town, the route is 2 miles long with 10 foot wide sidewalks along each side. If the crowd is approximately 5 people per 16 square feet, how many people are estimated to be watching?

Answers

Answer:

66 000 people

Step-by-step explanation:

Hi there !

1 mile = 5280 feet

2 miles = 2×5280ft = 10 560 feet

Area = 2(10560ft×10ft) = 2×105600ft² = 211200 ft²

How many people are estimated to be watching?

16 ft² ................ 5 people

211200 ft².........x people

x = 211200×5/16

= 1056000/16

= 66 000 people

9.The Bridgeport water department has a monthly service charge of $12.60 and a volume charge of
$1.38 for every 100 cubic feet of water. Write an equation that can be used to determine the Morgan
family's monthly water bill.

Answers

[tex]y = 1.38x + 12.60[/tex]

Step-by-step explanation:

the 12.60 is going to be charged every months no matter what it's fixed so that's why it's added! the 1.38 is a rate, so how many cubic inches she uses in increments of 100 she will be charged so that depends on how much she uses in addition to that 12.60for example she uses 700 cubic feet of water once month well (x) will be 7 because u divide it by 100 and it'll give u ur "x". put it into the formula and it'll give the price she'll have to pay. 1.38(7) + 12.60 and this will equal $21.70 !
