part b

1. which of the following lines of best fit represent the data if x is the number of days since the plant appeared and y is the height of the plant?

a. y = –3.5x + 0.7 wrong

b. y = –0.7x + 3.5 wrong

c. y = 0.7x + 3.5 wrong

d. y = 3.5x + 0.7 correct

2. explain why your choice of equations best fits the data. explain what the slope and y-intercept of the line of best fit mean about the bamboo plants.

part c

use the line of best fit chosen in part b to predict the height of a bamboo plant 40 days after appearing above the soil. show your work.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
