If r = [−3, 1] × [0, 2], use a riemann sum with m = 4, n = 2 to estimate the value of (y2 − 2x2) da. r take the sample points to be the upper left corners of the squares.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

what shape is

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
