Ethel was installing a sprinkler system. She cut a 20 m length of plastic tubing into two pieces. The longer piece was 2 m longer than twice the shorter piece. Let l represent the length of the longer piece and let s represent the length of the shorter piece.

Choose the two equations that will create our system of equations for this story problem.

2s+2l=20

s=2l+2

l+s=20

l=2s+2

How do i start to solve? would appreciate a walk-thru! a bird sitting 16ft above the ground in an apple tree dislodges an apple. after how many seconds does the apple land on the ground? (assuming that no branches will interfere with it's fall)

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
