What transformations are needed to change the parent cosine function to y=3cos(10(x-

The graph of is:

*Stretched vertically by a factor of 3

*Compressed horizontally by a factor  

*Moves horizontally units to the rigth

The transformation is:

Step-by-step explanation:

If  the function  represents the transformations made to the graph of  then, by definition:

If   then the graph is compressed vertically by a factor c.

If   then the graph is stretched vertically by a factor c

If  then the graph is reflected on the x axis.

If The graph moves horizontally b units to the left

If The graph moves horizontally b units to the rigth

If the graph is stretched horizontally  by a factor

If the graph is compressed horizontally by a factor

In this problem we have the function and our parent function is

The transformation is:

Then  and and

Therefore the graph of is:

Stretched vertically by a factor of 3.

Also as the graph is compressed horizontally by a factor   .

Also, as The graph moves horizontally units to the rigth

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
