Prove that quadrilateral ABCD with the vertices A(2, 1), B(1, 3), C(-5, 0), and D(-4, -2) is a rectangle. (CHECK PIC BELOW)

Adriveway is 40 yards long about how many meters long is it

The measure of angle 0 is 600 degrees

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
