a. No, because there are more students who do not have long hair than
students who do have long hair.

b. Yes, becatise there are more students with long hair wearing jeans, then there are students who do not have long hair and wear jeans.

c. Yes, they are associated (not independent) because knowing if a student wears jeans has changed our opinion.

d. No, becatise they can occur at the same time.

1. A curve is given by the following parametric equations. x = 20 cost, y = 10 sint. The parametric equations are used to represent the location of a car going around the racetrack.
a) What is the cartesian equation that represents the race track the car is traveling on?
b) What parametric equations would we use to make the car go 3 times faster on the same track?
c) What parametric equations would we use to make the car go half as fast on the same track?
d) What parametric equations and restrictions on t would we use to make the car go clockwise (reverse direction) and only half-way around on an interval of [0, 2?]?
e) Convert the cartesian equation you found in part “a” into a polar equation? Plug it into Desmos to check your work. You must solve for “r”, so “r = ?”

Concavity and critical numbers

I am attempting to study for a test, but I forgot how to do all the stuff from earlier in the chapter.

I am attempting to find the intervals where f is increasing and decreasing, min and max values and intervals of concavity and inflection points.

I have $f(x)={e}^{2x}+{e}^{-x}$. I know that I have to find the derivative, set to zero to find the critical numbers then test points then find the second derivative and do the same to find the concavity but I don't know how to get the derivative of this. Wolfram Alpha gives me a completely different number than what I get.
