Figure efgh on the grid below represents a trapezoidal plate at its starting position on a rotating surface:

the plate is rotated 90° about the origin in the counterclockwise direction. in the rotated trapezoid, what are the coordinates of the endpoints of the side congruent to side ef?

a.(−8, −4) and (−5, −7)

b.(−8, −4) and (−5, −2)

c.(4, −8) and (2, −5)

d.(4, −8) and (7, −5)

The annual snowfall in a town has a mean of 38 inches and a standard deviation of 10 inches. last year there were 63 inches of snow. find the number of standard deviations from the mean that is, rounded to two decimal places. 0.44 standard deviations below the mean 2.50 standard deviations below the mean 0.44 standard deviations above the mean 2.50 standard deviations above the mean

Find the magnitude, correct to two decimal places, made by each of the following with positive direction of the x axis a) y= x the answer is 45° but i don’t know how

Factor the polynomial by its greatest common monomial factor.
