A helicopter heads due east at a speed of 9 kilometers per minute. A crosswind to the northwest causes a change in the helicopter's direction and speed to 30° north of east at 7 kilometers per
minute. What are the components of the vector that describe the change in velocity?
V
Δy
30°
V
(-2.9, 3.5
(-1.7, 1.0)
(-0.8, 4.5)
(-5.5, 6.1)

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

1 a and 2 b

hope this

i think i remember taking that quiz.

a.

but im not sure so don't count on me.
