Write the ratios for sin A and cos A. The triangle is not drawn to scale

Bumek [7]

Answer:

$sin(A)=\frac{48}{50}$ , $cos(A)=\frac{14}{50}$

Step-by-step explanation:

Part a) Find the sin(A)

we know that

In the right triangle ABC

$sin(A)=\frac{BC}{AB}$ ----> the sine of angle (A) is the opposite side angle (A) divided by the hypotenuse

substitute the values

$sin(A)=\frac{48}{50}$

Part b) Find the cos(A)

we know that

In the right triangle ABC

$cos(A)=\frac{AC}{AB}$ ----> the cosine of angle (A) is the adjacent side angle (A) divided by the hypotenuse

substitute the values

$cos(A)=\frac{14}{50}$

Mrs. Williams put $500 into a retirement account that earns 4% interest. How long will it take for there to be $3,500?

Lisa [10]

Answer:

A = 500

B = 1.04

49.6 years

Step-by-step explanation:

We assume your 'A' and 'B' refer to parameters in an exponential formula of the form ...

y = A·B^x

In this form, A is the initial investment value, $500. B is the growth factor, 1+4% = 1.04, assuming interest is compounded annually. We want to find x such that y=$3500.

3500 = 500·1.04^x . . . . . fill in known values

7 = 1.04^x . . . . . . . . . . . . . divide by 500

log(7) = x·log(1.04) . . . . . . take logarithms

x = log(7)/log(1.04) ≈ 49.61 . . . . divide by the coefficient of x

It will take about 49.6 years for there to be $3500 in Mrs. Williams's account.

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]

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.
