Sec x = -11/5 [a] Find cos(−x) .
[b]Find the reference angle for x in radians.
Round your answer to 4 decimal places.
[c] If 0 ≤ x < 2pi , find all possible values of x in radians
[d] Using identities find all possible values of cot x

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

wait nvm i know the correct answer now its 100%   81 square feet
