Answer: 480

Step-by-step explanation:

We can create a ratio for this!

We have:

\frac{number of hamburgers}{total students}= \frac{new number of hamburgers}{new number of students}

We can use substitution to input the information we already know:

\frac{12}{30} = \frac{x}{1200}

Using cross multiplication, we get:

1 200(12) = 30x

14,400 = 30x

\frac{14,400}{30}=\frac{30x}{30}

x = 480

Hope this helps! :)

If f(x) = 5^x2 - 3 and g(x) = x2 - 4x - 8, find (f - g)(x).
kkurt [141]

Answer:

4x² + 4x + 5

Step-by-step explanation:

Note that (f - g)(x) = f(x) - g(x), thus

f(x) - g(x)

= 5x² - 3 - (x² - 4x - 8 ) ← distribute parenthesis by - 1

= 5x² - 3 - x² + 4x + 8 ← collect like terms

= 4x² + 4x + 5

Verifying Trig Functions
anzhelika [568]

Answer:

The answer to your question is below

Step-by-step explanation:

                csc α - cot α = \frac{sin \alpha }{1 + cos \alpha }

Work with the left part

                \frac{1}{sin\alpha } - \frac{cos \alpha }{sin \alpha}

Simplify

                \frac{1 - cos\alpha }{sin\alpha }

Multiply by the reciprocal

 \frac{1 - cos\alpha }{sin \alpha } x \frac{1 + cos\alpha }{1 + cos\alpha }                                  

Simplify

\frac{1 - cos^{2}\alpha}{sin\alpha (1 + cos\alpha)}

Remember that

                 sin²α = 1 -cos²α

Substitute the previous equation

\frac{sin^{2}\alpha }{sin\alpha(1 + cos\alpha ) }

Simplify

\frac{sin\alpha}{1 + cos \alpha}      

The identity i proved.
