Answer:

Your answer would be B: 30 ft squared

Step-by-step explanation:

Find the area of the circle: 5.5 (radius) multiply it by itself then multiply that by 3.14 which gets you 94.985. Now find the area of the square which is 8*8 = 64. Subtract 64 from 94.985 and your answer will be 30.985. The questions asks for the approximate (estimate), so the closest one would be 30 ft squared

Which of the following quadratic regression equations best fits the data shown below

attashe74 [19]

Let
A (-4,35)
B (-3,20)
C (-2,10)
D (-1,5)
E (0,8)
F (1,10)
G (2,15)
H (3,30)
I (4,48)

using a graph tool

case a) y=2.23x²+1.62x+5.26
see the attached figure N 1

case b) y=4.63x²+0.84x+4.14
see the attached figure N 2

case c) y=0.98x²+3.06x+6.02
see the attached figure N 3

case d) y=3.72x²+2.94x+3.21
see the attached figure N 4

using a Quadratic Regression Calculator
the Best Fit Second-Degree Quadratic Regression is
2.228x²+1.617x+5.255
see the attached figure N 5

therefore

the answer is
case a) y=2.23x²+1.62x+5.26
