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)

Marianna [84]
25% is .25 as a decimal 100*.25=25 so 25% of 100 is equal to 25 because, 25% goes into 100% 4 times so we immediately know that where looking for a number that can go into 100 4 times and it just so happens that 25=25 is true and 100=100 is true so are answer is literally in the question.

Answer:

a  26

b  8  2/3

Step-by-step explanation:

a)  4 1/3 * 6

Change the mixed number to an improper fraction

(3*4+1)/3 *6

13/3 *6

= 78/3

= 26


b)  2 3/5 * 3 1/3

Change the mixed numbers to  improper fractions

(5*2+3)/5   * (3*3+1)/3

13/5 *  10/3

130/15

Top and bottom divide by 5

26/3

Change back to a mixed number

3 goes into 26  8  times  (3*8 =24)   with 2 left over

8 2/3
