y=-0.215x^2+35
Step by Step:
Let, , , ,
We know that, the general equation of the parabola.
Substitute the value of in equation and find the value of
Hence, the equation of the parabola is:
It's greater than 117.859. Hope this helps
2x^3-42x-40=0
2x^3-42x=40
2x(x^2-21)=40
a. 2x=40=>x=20
b. x^2=21+40=>x^2=61=>x=+-(radical(61)
