Step-by-step explanation: see picture
Answer:
f(-6) = 4
Step-by-step explanation:
f(-6)
The x value is -6
We want to find the y value of the graph at x= -6
The y value is 4
f(-6) = 4
Answer:
cos0 = 6.8556546i/23 or sqrt-47/23
Step-by-step explanation:
hypotenuse is 23, opposite is 24
we have to find the adjacent using the pythagorean theorem
24^2 + b^2 = 23^2
576+b^2=529
subtract
b^2=-47
b=sqrt-47
sqrt of -47 is 6.8556546i, there is an i since it is the square root of a <em>negative</em>
cos = adjacent/hypotenuse
