If the point P(-4/5,y) lies on the unit circle and P is in the third quadrant, what does y equal? If necessary, use the slash ma

aleksandr82 [10.1K]

We use the fact that x2+y2=1 This is the equation of the unit circle.
We know that x=-4/5, so plug this in and solve for y
x2+y2=1 (−4/5)^2+y2=1 16/25+y2=1 y2=1−16/25 y2=9/25 y=−square root of 9/ 25
y = -3/5

One number is 20 times another number. The product of the two numbers is 180. Write an equation and use it to find all pairs of

nadezda [96]

Y = 20x

y • x = 180

180/x = y

180/x = 20x

180 = 20x^2

x^2 = 6

x = + or - 3

Therefore y must equal + or - 60.

Step-by-step explanation:

rectangle + 2 triangle = total area

L x W + 2 * 1/2 base * height = total area

(5x12) + 2 * 1/2 * 12 * 4 = total area

60 + 48 = 108 cm^2
