I WILL GIVE BRAINLIEST PLEASE HELP FULLY (pt 8) 8. Andy is a stock analyst who is evaluating MXC and BPP. On July 12, 2010, the price of MXC before the open was $44.20 per share, and it closed at $42.07 per share. The price of BPP before the open was $26.57 per share, and it closed at $23.43 per share. Help Andy compare the performance of these two stocks on this day. (5 points: Part I – 1 point; Part II – 1 point; Part III – 1 point; Part IV – 1 point; Part V – 1 point)
Part I: By how many dollars per share was MXC down for the day?

Part II: By how many dollars per share was BPP down for the day?

Part III: What was the rate of change for MXC for the day? Round your answer to the nearest hundredth of a percent.

Part IV: What was the rate of change for BPP for the day? Round your answer to the nearest hundredth of a percent.

Part V: If Andy is talking about dollars per share, which stock should he say was down more for the day? If he is talking about the rate of change, which stock should he say was down more for the day?

is there answer choices?

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
