1.) in the year 2005, the average cost of a car could be modeled by the equation c= -15x^2 + 20x - 3 where x is the number of years since 2005. by the year 2010 the average cost had changed, and the equation could be modeled by c= -10x^2 + 30x - 2. find the difference in average cost equation for cars between 2005 and 2010.

2.) the function p(x) = 3x^2 + 4x + 5,is dilated by the function i(x) = p(2x). write the new function i(x).

3.) make a box and whisker plot of the following data. show your work as to how you calculated the different key points on the box-and-whisker plot. 21, 25, 30, 27, 22, 23, 23, 24, 26, 28, 25, 22, 23

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
