Hello could anyone tell me the answer and the steps to do this problem. "A model rocket is launched fromground level into the air. Its height ,yin feet, after xseconds can be represented by the equation .25160xxy−=What is the total elapsed time, in seconds, from the time the rocket is launched until it reachesground level again?"

9

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

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.

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
