Use your graphing calculator to create the least square regression line for this data (rounding the slope to 3-decimals and the y-intercept to 2 decimals). Use the regression line function to predict the life span for an animal with a 470-day gestation period. An animal with a gestation period of 470 days would have an average longevity of years. Round your answer up to the nearest whole number of years.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
