Answer:

If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function. Using the vertical line test, all lines except for vertical lines are functions.

What are the amplitude, period, and phase shift of the given function? f(t)=-2/3 cos (3t-3pi)
dybincka [34]

Answer:

amplitude; \frac{2}{3}

Phase shift; \pi units right

Period;\frac{2\pi}{3}

Step-by-step explanation:

The given function is

y=-\frac{2}{3}\cos(3t-3\pi)

This function is of the form;

y=A\sin (Bt+C)

The period is given by:

|A|=|-\frac{2}{3}|= \frac{2}{3}

The period is given by:

T=\frac{2\pi}{|B|}= \frac{2\pi}{|3|}=\frac{2\pi}{3}

The phase shift is given by;

\frac{C}{B}=\frac{-\3pi}{3}=- \pi or \pi units right.

Alyssa can complete a job in 12 minutes. If Miranda helps her, they can complete the job in 9 minutes. How long would it take Mi
miv72 [106K]

Answer:

36 minutes

Step-by-step explanation:

The key is to get the same amount of time for each.

9 * 12 = 108

At 12 minutes per job,

in 108 minutes Alyssa could do

108/12 = 9 jobs

At 9 minutes per job,

Together in 108 minutes they could do

108/9 = 12 jobs

--------------------------

In 108 minutes Mirada does

12 - 9 = 3 jobs

108/3 = 36 minutes per job
