Find the size of each of 6 payments made at the end of each year into a 6% rate sinking fund which produces $82000 at the end of
Yuri [45]

Answer:

at the end of 1st year we pay $ 11756

at the end of 2nd year we pay $ 24217

at the end of 3rd year we pay $ 37426

at the end of 4th year we pay $ 51427

at the end of 5th year we pay $ 66269

at the end of 6th year we pay $ 82001

Step-by-step explanation:

Given data

rate ( i ) = 6%

Future payment  = $82000

no of time period ( n ) = 6

to find out

size of all of 6 payments

solution

we know future payment formula i.e.

future payment = payment per period ( (1 + rate)^{n} - 1 )   / rate

put all these value and get payment per period

payment per period = future payment × rate  /  ( (1 + rate)^{n} - 1 )   / rate

payment per period = 82000 × 0.06  /  ( (1 + 0.06)^{6} - 1 )   / rate

payment per period = 82000 × 0.06 / 0.4185

payment per period = $ 11756.27

at the end of 1st year we pay $ 11756

and at the end of 2nd year we pay $ 11756 × ( 1  + 0.06) + 11756

and at the end of 2nd year we pay $ 24217

and at the end of 3rd year we pay $ 24217 × ( 1  + 0.06) + 11756

and at the end of 3rd year we pay $ 37426

and at the end of 4th year we pay $ 37426 × ( 1  + 0.06) + 11756

and at the end of 4th year we pay $ 51427

and at the end of 5th year we pay $ 51427 × ( 1  + 0.06) + 11756

and at the end of 5th year we pay $ 66269

and at the end of 6th year we pay $ 66269 × ( 1  + 0.06) + 11756

and at the end of 6th year we pay $ 82001

MATH1099 First Week ActivityUse the object below to find the missing lengths of the two sides, x and y. Then find the perimeter
Marina CMI [18]

Answer:

x = 28

y = 21

The perimeter is of 224 cm.

Step-by-step explanation:

Finding x:

We look at the top, and the bottom of the figure.

The top measures 42 cm.

The bottom measures x.

Looking on the base of y, we can see that the top can be divided into a part which is x(same as the bottom), and another of 14, measuring 42. So

x + 14 = 42

x = 42 - 14

x = 28

Finding y:

Now we apply the same logic to find y.

We look at the left side, and the right side.

They should be equal.

The right side measures 70.

The left measures 49 + y. So

49 + y = 70

y = 70 - 49

y = 21.

Finding the perimeter:

It is the sum of all edges.

P = 42 + 70 + x + 49 + 14 + y

Since x = 28, y = 21

P = 42 + 70 + 28 + 49 + 14 + 21

P = 224

The perimeter is of 224 cm.
