If the radius of curvature of the convex side is 8.00 cm, find the magnitude of the radius of curvature of the concave side such that the lens will be diverging with a focal length equal to -16.4 cm. The lens is made of glass with an index of refraction equal to 1.58.

Step-by-step explanation:

As we  know, the focal length equal to -16.4 cm

<=> =  -16.4

<=> P(lens) = -5/82

But the formular of The Lens Maker is:

P(lens) = (n-1) ( - ) where:

<=>-5/82 = (1.58-1) ( - )

<=> = 4.345 cm

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

i believe the correct answer is b.
