the diameter of a parabolic mirror is 22 centimeters and the mirror has a depth of 0.5 centimeter at th center what is the equat
NeX [460]
I figured it out
warning: mildly incoherent math logic ahead


ok, so if you want a parabola facing right, then
first I'll solve for up down standard parabola then reflect across x=y line
so
y=ax²+bx+c

so let's say teh vertex is at the origin
that means when x=0, y=0
0=0
c=0
y=ax²+bx
ok, see diagram
we have some points, (0,0) and (11,0.5) and (-11,0.5)
use those oints to find a and b
0.5=121a+11b
0.5=121a-11b
add dem equations
1=242a
divide by 242
1/242=a
subsitute
0.5=121a+11b
0.5=121(1/242)+11b
0.5=0.5+11b
0=11b
0=b
oook

de equaiton is
y= \frac{1}{242} x^2
if we want it facing right
switch x and y
x= \frac{1}{242} y^2



the equation is y= \frac{1}{242} x^2 or f(x)= \frac{1}{242} x^2 or x= \frac{1}{242} y^2 or f(y)= \frac{1}{242} y^2
depends which way you want it and if you want f(x) or f(y) or x or y

the graph below plots a function f x if x represents time the average rate of change of the function f x in the first three seco
Vinvika [58]

Answer:

-50

Step-by-step explanation:

rate of change = slope so you were asked for the slope between the point in which x = 0 (0,150) and the point in which x=3 (3,0)

Here is how you calculate it:
