$\frac{x}{15} = \frac{4}{5} \\ Change\ both\ fractions\ to\ a \\ common\ denominator, \\ \\ \frac{x}{15} = \frac{4 \times 3}{5 \times 3} \\ \frac{x}{15} = \frac{12}{15} \\ x = 12$

Help. only questions 3 & 4 .

Maksim231197 [3]

I'm doing 3

For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

Hope this helped!

Graph g is a translation of the graph of y= sin x (dashed line).a) write down the equation of g b) write down the coordinates of

labwork [276]

Answer:

<em>a) </em> $G(x)= \sin x + 2$ <em />

<em>b) The coordinates of P are</em>

<em /> $\displaystyle \left( \frac{3\pi}{2},1\right)$

Step-by-step explanation:

<u>Translation</u>

The dashed line shows the graph of the function

$y = \sin x$

This function has a maximum value of 1, a minimum value of -1, and a center value of 0.

a)

Graph G shows the same function but translated by 2 units up, thus the equation of G is:

$\boxed{G(x)= \sin x + 2}$

b) The coordinates of P correspond to the value of

$x = \frac{3\pi}{2}$

The value of G is

$\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2$

Since

$\sin \frac{3\pi}{2}=-1$

$\displaystyle G(\frac{3\pi}{2})= -1+ 2=1$

The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$
