X If $7500 was compounded annually for 8 years at a rate of .23% how much will it be

Ann [662]

Answer:

$7639.12

Step-by-step explanation:

We use the compound formula for accrued value (A) for a principal P deposited at an annual rate "r" over t years

$A = P (1+r)^t$

In our case, with the given information, the formula becomes:

$A = P (1+r)^t\\A=7500 \,(1.0023)^8\\A = 7639.11602$

which rounded to the nearest cent gives: $7639.12

A circle is inside a square as shown.

Harrizon [31]

Answer:

9.76m²

Step-by-step explanation:

The area of the square is

$Area = {s}^{2}$

where s=8m is the side length.

This means that:

$Area = {8}^{2} = 64 {m}^{2}$

The area of a circle is

$Area = \pi \: {r}^{2}$

From the diagram, the diameter is 8m.

This means that the radius is

$r = \frac{8}{2} = 4m$

The area of the circle then becomes,

$Area =3.14\: \times {4}^{2} = 3.14 \times 16$

$Area = 50.24 {m}^{2}$

The area of shaded region is area of square minus area of circle.

$Area \: of \: shaded \: region = 64 - 50.24 = 9.76 {m}^{2}$

Devin runs a factory that makes Blu-ray players. Each R80 takes 9 ounces of plastic and 2 ounces of metal. Each G150 requires 3

alexira [117]

9514 1404 393

Answer:

R80: 12

G150: 54

Best Profit: $582

Step-by-step explanation:

Let x and y represent the numbers of R80 and G150 players, respectively. The constraints of the problem are ...

0 ≤ x ≤ 18 . . . . . a maximum of 18 R80 can be built

0 ≤ y . . . . . . . . . only non-negative numbers can be built

9x +3y ≤ 270 . . . . ounces of plastic used cannot exceed 270

2x +6y ≤ 348 . . . . ounces of metal used cannot exceed 348

The objective is to maximize the profit function ...

P(x, y) = 8x +9y

The attached graph shows profit is a maximum of $582 per week when 12 R80 players and 54 G150 players are produced.

_____

Since the maximum profit is at a value of x less than 18, we didn't bother to graph that constraint.
