The values of θ are in radians and are between 0 and 2π . Enter your answer in exact form. I needed to enter in a smaller value and a larger value. However, I got the answers of pi/4...

(Do not include the endpoints of the intervals, and all intervals should be open intervals on all endpoints) I don't really understand the instructions here. This is one of a few...

(Determine the radius, r centimeters, of the circle. Write an exact number as an integer, fraction, or decimal.) I'm very confused about arcs and angles and whatnot. I'm doing extra...

One gear wheel turns another the teeth being on the rims. The wheels have 40cm and 50cm radii, and the smaller wheel rotates at 20rpm. find angular speed of larger wheel in radians per second

Find all solutions to the equation on [0,2π) sinxcotx^2-sinxcsc^2 x=1/2

How many times did the wheel rotat? How many radians did it turn? ps. I need to know how to get the answer, thx!

i need help understanding word problems in precalculus algebra.

A farmer finds that if she plants 75 trees per acre, each tree will yield 20 bushels of fruit. She estimates that for each additional tree planted per acre, the yield of each tree will decrease by...

I'm having trouble solving the above question, as well as the one below tan20+tan10/1-tan20tan10=

how do i establish identity

For this problem, I used the formula of A=P(1+r/n)nt to get to A=8000(1+0.06/4)4*7, which would give the answer of $12,137.77. Is this answer correct and, if not, how would I arrive...

I need to find what the smaller and larger x intercepts are, but I'm not sure how to do that (and it's a homework question with a topic that hasn't yet been covered in class) From what I've been discovering,...

a) Write the area of the corral as function of x, so A(x)=? b) Determine the maximum area enclosed by the corral. (Decimal approximations are marked incorrect.) So the maximum area equals...

I tried solving this one (I'm trying to only ask questions on here that i've tried solving lol), however, I keep getting the domain of (-infinity, infinity). However, my teacher said that that answer...

I need to find what the smaller and larger x intercepts are, but I'm not sure how to do that (and it's a homework question with a topic that hasn't yet been covered in class)

The inverse in this question is a function of y. What would "(f ○ g)−1(y) =" equal. I got the answer (-x+25)/18 (or 25/18-x/18). However, this answer is wrong. Should I just sub out...

There are many ways to do this. One way is to only use the set of positive, real numbers of the form [a,∞). Determine a value of a so that it is the smallest possible, positive real number where...

The function f(x) = −12 x^2 + 6x + 5 is not invertible, however the domain can be restricted so that the function is invertible only on the restricted domain. There are many ways to...
