Answer:

y = sin(x- pi/2)

Step-by-step explanation:

Please see the attached image to see your graphs.

By simple inspection we can see that the sine is shifted pi/2 to the right.

We know this because sines are periodic functions with a period T = 2*pi

We can also see that the maximum point of the graph (y = 1) got shifted by a fourth of the period.

And finally, since we want to shift the graph to the right, we need to substract from the argument of the sine term.

Answer:

Step-by-step explanation:

Given

a = $\frac{1}{x}$ - $\frac{1}{y}$ = $\frac{y-x}{xy}$ ← as a single fraction

Thus

$\frac{1}{a}$ = $\frac{1}{\frac{y-x}{xy} }$ = $\frac{xy}{y-x}$ → A

Mashcka [7]

Answer: he would receive a rebate of $1677.5

Step-by-step explanation:

A General Motors buyer-incentive program offered a 5.5% rebate on the selling price of a new car. This means that if the selling price of the new car is $x, the rebate (in dollars) that a customer would receive is

5.5/100 × x = 0.055 × x = 0.055x

Therefore, for a customer who purchased a $30,500 car under this program, the rebate that he would receive is

0.055 × 30500 = $1677.5

There are a total of 67,062 words

Equation:

67,062 / 300 = total number of pages

67,062 = 223.54

That means 224 pages, because the last page is partially filled.

For each logarithmic equation, write an equivalent equation in exponential form

Montano1993 [528]

Answer:

loga b = c ⇔ a^c = b

<u>Apply the property above:</u>

1. ln 618 = p ⇔ e^p = 618
2. ln q = 2 ⇔ e^2 = q
3. ln 100 = t ⇔ e^t = 100
4. ln (e^3) = 3 ⇔ e^3 = e^3
