Answer:

Step-by-step explanation

Each week a discount of 15% of the previous week.So the price will be 85% of the previous week (17/20 of the previous price)

We multiply the price from the previous week  by 0.85 to obtain the new price  

200 x 0.85 = 170

170 x0.85 = 144.50.....and so on

3)$ 122.82

4$)104.40

5).$88.74

6)$75.42

The shoes will be less than half in week 5

                 

 DECAY

The friend is not right

$30 less was only the first week

Each week the saving will be 85% of the  previous week. But the shoes will not be free in 2 months  On the week 8 the price will be $54.50

Find the amplitude, period, and phase shift of the function defined by:<br> y=3-2cos(3x+pi)
sergeinik [125]
This is a sinusoidal wave with an <u>amplitude of 2</u> , riding on a constant value of 3 .
The 3 isn't part of the function's amplitude ... the function wiggles between 2 under it
and 2 over it.

The period of the function is the change in 'x' that adds (2 pi) to the angle.

When x=0, the angle is pi

When the angle is (3 pi) . . .

3 pi = 3x + pi 
2 pi = 3x
x = 2/3 pi  <u>The period of the function is 2/3 pi </u>.

When x=0, the function is cos(pi) rather than cos(0).
So the function is a cosine with a <u>phase shift of +pi</u>.
It could also be described as a sine with a phase shift of -pi/2 or +3pi/2 .

Answer:

One solution is, (3,2)

One solution is, (-1,1)

There are infinitly many solutions

The equation of the line is  y=\frac{1}{4} x+\frac{5}{4}

Step-by-step explanation:

Anything on the line is a solution.

The line is infinite therefore the solutions are also infinite.

The dot (3,2) and (-1,1) are both on the line therefore they are both solutions.

The slope of the line is 0.25 or 1/4 so we know the first part of the equation.

y = 1/4x

The y-intercept is on the point 1.25 or 5/4

We now know the whole equation

y = 1/4x + 5/4

To double check you can plug in points into the x and y spots on the equation or as I did graph it.
