Answer:
y = - 9.1768x2 + 122.2567x + 14.9091
Step-by-step explanation:
Given the following :
Month (x) Daily Rental Price (y) 1 $154 2 $205 3 $266 4 $358 5 $403 6 $425 7 $437 8 $430 9 $381 10 $285 11 $211 12 $195
Using the online regression equation graphing tool ; The quadratic model obtained in the form,
y = Ax^2 + Bx + C is :
y = - 9.1768x2 + 122.2567x + 14.9091
Attached below is a picture of the quadratic regression curve.
Answer:
The answer is "2x-y=4"
Step-by-step explanation:
Given:
The Formula of Slope:
by replacing the (2,0) and (0,-4) coordinates in the above formula:
if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.
Equation of the line:
apply m and c value in the above equation:
Subtract by 2x on both sides of the equation we get:
Answer: 18.7
Step-by-step explanation:
Find the lengths of AB, BC, and CA
AB = = 5
≈ 7.1
BC = = 5
≈ 7.1
CA = = 2
≈ 4.5
7.1 + 7.1 + 4.5 = 18.7
