So check the picture below

recall your SOH CAH TOA \bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}

which identity uses only
angle
opposite
adjacent?

well, is Ms Tangent.. thus  \bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(54^o)=\cfrac{1200}{x}

solve for "x", make sure your calculator is in Degree mode, since the angle is in degrees

Write an equation for a rational function with: vertical asymptotes at x = 2 and x = -5 x-intercepts (-1,0) and (1,0) horizontal
solong [7]

Given vertical asymptotes x = 2 and x = -5 .

Therefore Factors of denominator (x-2)(x+5).

x-intercepts (-1,0) and (1,0) .

Therefore factors of (x+1)(x-1).

So far we got rational function = \frac{(x+1)(x-1)}{(x-2)(x+5)}.

Now, we are given horizontal asymptote at y = 9.

Multiplying above express by 9 on the top, we get

f(x)=\frac{9(x+1)(x-1)}{(x-2)(x+5)}.

<h3>Therefore, required rational function is f(x)=\frac{9(x+1)(x-1)}{(x-2)(x+5)}.</h3>

Hey can you please help me posted picture of question
Lorico [155]
This is a TRUE statement. 

Consider the following example:

5 can also be written as 5x^{0}. Any variable raised to power 0 is equal to 1. So x raised to power 0 is equivalent to multiplying by 1, it leaves the expression/number unchanged. 

So yes, polynomial of degree zero is a constant term
