For tan(405 degrees):

405° = 360° + 45° = 45° = 9π/4 = π/4 

tanx = sinx/cosx 

sin(π/4) = √2/2 

cos(π/4) = √2/2 

[√2/2] / [√2/2] = 1 

<span>Therefore: tan(405°) = 1
</span>
You may use the same method for the other given functions.

Answer:

25, 90, and 65

Step-by-step explanation:

so the measures have to add up to 180, because it's a triangle, and we know 25 and 90 ( the box corner thing means that angle is 90) so we add 25 and 90 to get 115, and then we subtract 115 from 180, which gets us 65.

Please help with 32 and 33, thank you.

Answer:

32. ∛((x-7)/4) = f^(-1)(x)

33. -10x - 9

Step-by-step explanation:

32. We want to switch f(x) and x, and then solve for f(x) to get the inverse.

x = 4f(x)³ + 7

subtract 7 from both sides

x -7 = 4f(x)³

divide both sides by 4

(x-7)/4 = f(x)³

cube root both sides

∛((x-7)/4) = f(x)

make f(x) f^(-1)(x) because this is now the inverse

∛((x-7)/4) = f^(-1)(x)

the second answer is correct

33. for composition, we can treat (f · g) (x) as attached picture (content filter!), so we plug g(x) into f(x). This results in

2(-5x-7) + 5

expand

-10x - 14 + 5

add

-10x - 9

the second answer is correct
