Fill in the blank. if necessary, use the slash marks (/) for a function bar. if sin theta= 3/5, then cos theta=

4/5 or -4/5

Step-by-step explanation:

We are going to use the Pythagorean Identity:

We are given the value of which is 3/5 so plug that in:

Simplify:

Subtract 9/25 on both sides:

Take the square root of both sides:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

ab will be equal to
