Write a percent porportion and solve each number the numbers are 22 is 44% of what number?
Irina-Kira [14]

Answer:

The number is 50.

Step-by-step explanation:

If we express the percentage x% in the form of ratio then it can be written as \frac{x}{100}.

Now, it is asked which number if we make 44 % will give 22.

Let the number is given by x.

Then expressing the % as ratio we can write \frac{22}{x} = \frac{44}{100}

⇒ x=\frac{22 \times 100}{44} = 50 ( Answer )

Rewrite y= (square root all) 9x+45 (non sqrt) -2 to make it easy to graph using a translation. describe the graph
iVinArrow [24]

Answer:

(i)

shifted left side by 5 units

(ii)

vertically stretch by 3 units

(iii)

shifted vertically downward by 2 units

Step-by-step explanation:

we are given

y=\sqrt{9x+45} -2

we can also write as

y=\sqrt{9(x+5)} -2

we can factor out 9

y=3\sqrt{(x+5)} -2

Firstly, we will identify parent function

y=\sqrt{x}

step-1:

We can see that there is x+5 in place of x

so, f(x) will be shifted left side by 5 units

step-2:

3 is multiplied to sqrt

so, it is vertically stretch by 3 units

step-3:

-2 is added to y-value

so, it is shifted vertically downward by 2 units
