Answer:
equation is the best model of the data: y=0.5x+2.4
Step-by-step explanation:
y=2.8(1.1^x)
try two points (2,3.5) and(1,3)
find m=y2-y1/x2-x1
m=3-3.5/1-2=
m=0.5
find b at point 1,3
y=mx+b
3=0.5(1)+b
b=3-0.5
b=2.5
Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.
The vertex point is (0,12)
the axis of symmetry is 0
The zeros are (-4,0) and (4,0)
using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)
Your answer is 8

Hope this helps you!
P.S. Can i get brainliest? :)
