The equation yˆ=1.21x2−15.98x+156.28 approximates the average cost, in thousands of dollars, of a home in a particular county, x years after the data collection began. What is the best estimate for the average cost of a home 4 years after the data collection began? rounded to the nearest tenth, in the box.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

answer:

your answer is: c. 196 7/8 in^3.
