I really really need help!!!!!!

Svetllana [295]

ANSWER

$y = 5 \sin( \frac{6}{5} x - \pi)-4$

EXPLANATION

The given function is

$y = 5 \cos( \frac{3}{5} x - \pi) + 4$

The period of this function can be determined using the formula:

$T= \frac{2\pi}{ |b| }$

The period is

$T= \frac{2\pi}{ \frac{3}{5} } = \frac{10\pi}{3}$

Half the period of this function is:

$\frac{ \frac{10\pi}{3} }{2} = \frac{5\pi}{3}$

The function which has this period is

$y = 5 \sin( \frac{6}{5} x - \pi) -4$

The first choice is correct.

Which is equivalent to 2^-3/2^2

Veronika [31]

Answer:

$1/32$

Step-by-step explanation:

To understand this question you would first of all need to know about negative exponents and multiply fraction by integers.

Example I would like to find out $2^{-2}$ ,

You would first normally solve this question by squaring, which would result in 4 then divide it by 1. Like this: $1/2^{2}$

Which would be 0.25 or 1/4

Lets apply this knowledge to the following question:

1. $2^{-3} / 2^{2}$

2. $\frac{1}{8} / 4$

3. $1/32$
