The equation for this parabola satisfies

(in other words, plug in each given point's coordinates
into the equation
)
Now,


and



So the equation of the parabola is

Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
I think it’s 25.12 or C
to find circumference u multiply diameter by 3.14.
to find radius you multiply diameter by 2
diameter is 4. multiply diameter by 2 and u get 8
8 x 3.14= 25.12
89/100 because the percent is out of 100 so it’s the same thing as 89/100
