Use the distance formula to find the distance between points A and B. The distances between points A and C and between points B and C should be the same (half of the distance between A and B).
Sqrt((x1-x2)^2 + (y1-y2)^2)
So the answers are Yes, Yes, and No
6.22222222222
2 over 3 to the power of 2 + 5 × 2 − 4=6.22222222222
The machinist can produce 285 parts in 15 minutes. I know this because:
114 divided by 6 is 19. 19 multiplied by 15 is 285.
His average is 80%. You take the two scores add them up and divide by the number of scores.
Answer:
(-1, 1), (-2, 2), and (-1, 3)
Step-by-step explanation:
The formula for rotation of a point (x,y) by an angle θ about the origin is
x' = xcosθ - ysinθ
y' = ycosθ + xsinθ
If θ = 90°, sinθ = 1 and cosθ = 0, and the formula becomes
x' = -y
y' = x
P: (1, 1) ⟶ (-1, 1)
Q:(2, 2) ⟶ (-2, 2)
R: (3, 1) ⟶ (-1, 3)
The vertices of P'Q'R' are (-1, 1), (-2, 2), and (-1, 3).
The Figure below shows the triangle before and after the rotation.
