Please help, Describe the transformation of the graph of the parent function y = √x for the function y = √x + 7 + 5.

Setler79 [48]

Answer:

C. Up.

Step-by-step explanation:

We have been given that the parent function $y=\sqrt{x}$ is transformed to the function $y=\sqrt{x+7}+5$ . We are asked to describe the given transformation.

Let us recall the transformation rules.

$f(x+a)=\text{Graph shifted to left by a units}$ ,

$f(x-a)=\text{Graph shifted to right by a units}$ ,

$f(x)+a=\text{Graph shifted upwards by a units}$ ,

$f(x)-a=\text{Graph shifted downwards by a units}$ .

Upon comparing our transformed function with the parent function, we can see that the graph is shifted to left by 7 units and upwards by 5 units.

Therefore the correct choice is option C.

Ava estimates that 475 songs will fit on her iPad. The actual amount of songs that fit is 350. Find her percent of error.

alukav5142 [94]

Given:

Ava estimates that 475 songs will fit on her iPad.

The actual amount of songs that fit is 350.

To find:

The percent of error.

Solution:

We know that,

$\text{Percent error}=\dfrac{\text{Estimated values - Actual value}}{\text{Actual value}}\times 100$

Putting the given values, we get

$\text{Percent error}=\dfrac{475-350}{350}\times 100$

$\text{Percent error}=\dfrac{125}{350}\times 100$

$\text{Percent error}=\dfrac{250}{7}$

$\text{Percent error}\approx 35.71\%$

Therefore, the percent of error is 35.71%.
