Printer 1:

y = .25p + 5

Printer 2:

y = .20p + 10

.25p + 5 < .20p + 10

.05p + 5 < 10

Angle M + Angle N = 159

(4y+3)+(6y+6)=159

y = 15

Angle M = 4y + 3 = 4(15) + 3 = 63

Angle N = 6y + 6 = 6(15) + 6 = 96

A billiard ball is struck by a cue. It travels 120 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the
ball approaches the rail and the path after it strikes the rail is 40 degrees. How far is
the corner pocket from where the cue initially struck the ball? Round your answer to the nearest centimeter.

Answers

The angle between incident and reflection is 45 degrees not 90 degrees, so we need to use the cosine rule:

a^2 = 100^2 + 120^2 - 2*100*120*cos(45°) where a is the distance between pocket and initial strike.

so a = sqrt(100^2 + 120^2 - 2*100*120*cos(45°))

a = 86 cm (to the nearest cm).

Factor the polynomial completely.

9g^2 - 30gh + 25h^2

Answers

Answer:

Step-by-step explanation:

It's a perfect square.

It factors into (3g - 5h)^2

or (3g - 5h)(3g - 5h)

Make sure it is correctly factored.

3g*3g = 9g^2

3g * - 5h = - 15gh

-5h*3g = - 15gh

5h*5h = 25h^2

These four terms add to 9g^2 - 15gh - 15gh + 25h^2 = 9g^2 - 30gh + 25h^2 which is exactly what you started with.
