Assume the parent function has been shifted up
mars1129 [50]

Answer:

If y=(x-2)^2+4 is the transformed function, then the parent function y=x^2 has been shifted up vertically by 4 units and horizontally right by 2 units

Step-by-step explanation:

Assume the function is y=f(x) is the parent function.

A vertical shift,b units up  will transform the function to y=f(x)+b .

A horizontal shift a units.

y=f(x-a)+b

For instance, if y=x^2, b=4, and a=2 units.  

Then the transformed function becomes:

y=(x-2)^2+4

Vilka [71]

Answer: MP=10, PN=6

Step-by-step explanation:

Suppose the poll in the previous question was conducted by email, and those conducting the survey are concerned about the possib
mr_godi [17]

Answer:

Throw this sample out and start over again with a better sampling method

Step-by-step explanation:

Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.

Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.

Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.

A closed box with a square base is to have a volume of 85. 75 cm^3. the material for the top and bottom of the box costs ​$3.00
tiny-mole [99]

We can create two equations here:

(1) Volume = area of square * height of box

85.75 = s^2 h

(2) Cost = 3 * area of square + 1.5 * area of side box

C = 3 s^2 + 1.5 s h

 

From (1), we get:

h = 85.75 / s^2

 

Combining this with (2):

C = 3 s^2 + 1.5 s (85.75 / s^2)

C = 3 s^2 + 128.625 s-

 

Taking the 1st derivative and equating dC/ds = 0:

dC/ds = 6s – 128.625 / s^2 = 0

Multiply all by s^2:

6s^3 – 128.625 = 0

6s^3 = 128.625

s = 2.78 cm

 

So h is:

h = 85.75 / s^2 = 85.75 / (2.78)^2

h = 11.10 cm

 

So the dimensions are 2.78 cm x 2.78 cm x 11.10 cm

 

The total cost now is:

C = 3 (2.78)^2 + 1.5 (2.78) (11.10)

C = $69.47
