the amount of each payment to be made into a sinking fund which earns 9% compounded quarterly and produces $43 comma 000 at th

Blizzard [7]

Answer:

$2647.18

Step-by-step explanation:

Data provided in the question:

Rate = 9% compounded quarterly

interest rate per period, i = 9% ÷ 4 = 2.25% = 0.0225

Future value = $43,000

Time = 3.5 years

Number of periods, = 3.5 × 4 = 14

Now,

Let the annual payments be 'A'

Thus,

Future value = A × [ (1 + i)ⁿ - 1 ) ÷ i ]

$43,000 = A × [ (1 + 0.0225)¹⁴ - 1 ) ÷ 0.0225 ]

$43,000 = A × 16.244

A = $2647.18

The length of a rectangle is 15 ft greater than its width. If each dimension is decreased by 2 ft, the area will be decreased by

padilas [110]

Answer:

length = 35ft, width = 20ft

Step-by-step explanation:

We are working with length (L), width (W), and area (A). We are asked to find the 2 dimensions. The question tells us that L = W + 15, so we can express L in terms of W. However, we still don't know what A is. Since we have 2 unknowns, we somehow need to develop 2 equations to get a solvable system.

We can set up the first equation using the relationship between L and W:

$W(W+15)=A$
