Given: △PRS, RS=10 m∠P=45°, m∠S=60° Find: Perimeter of △PRS

Keith_Richards [23]

The law of sines can be used to find the missing side lengths.

... RP = sin(60°)/sin(45°)·10 = 10√(3/2) ≈ 12.247

... PS = sin(75°)/sin(45°)·10 ≈ 13.660

Then the perimeter is

... perimeter = RS + RP + PS

... = 10 + 12.247 + 13.660 ≈ 35.91 . . . .units

Find the range of each function when the domain is {-3, -2, 2, 3} f(x)=5x-6

saw5 [17]

Answer:

-21, -16, 4, 9

Step-by-step explanation:

-3: f(-3) = 5(-3)-6 = -15-6 = -21

-2: f(-2) = 5(-2)-6 = -10-6 = -16

2: f(2) = 5(2)-6 = 10 - 6 = 4

3: f(3) = 5(3)-6 = 15 - 6 = 9
