Answer:

C

Step-by-step explanation:

The addition formula for the tangent ratio is

tan(x + y) = \frac{tanx+tany}{1-tanxtany}

Thus the expansion of

tan(60 + 45) = \frac{tan60+tan45}{1-tan60tan45} → C

Nimisha wants to draw a wheel like the one shown. Each shaded part of the wheel should be one-third of each unshaded part. What
ivolga24 [154]

Answer:

Each shade has a 22.5 degree angle from the middle

Each unshaded has a 67.5 degree angle from the middle.

Step-by-step explanation:

You can solve this by making each unshaded part equal to x and each shaded part equal 1/3x it is a circle so it has to equal 360 so you end up with:

x + 1/3x + x + 1/3x + x + 1/3x + x + 1/3x = 360

Combine Like terms:

16/3x = 360

Multiply both sides by the opposite:

(3/16) (16/3x) = (360) (3/16)

x=135/2 or x=67.5

Then you can plug 67.5 in for x:

1/3x ---> 1/3(67.5) = 22.5

Which is an odd monomial function? A.y=2x^3 B.1/x C.5x^-9 D.3
Anna71 [15]
First let's review two concepts:
 Monomy: Algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
 Odd function: A function is odd if, for each x in the domain of f, f (- x) = - f (x).
 The function y = 2x ^ 3 complies with both definitions.
 Answer:
 an odd monomial function is:
 
A.y = 2x ^ 3
