Find missing lenghts and degrees to the nearest tenth if m<C =100, a=9.5, and b=7.1 Find c

If p is the length of the perpendicular from the origin on the line x/a + y/b = 1 and a^2,p^2,b^2 are in A.P.Then a^4-2a^2p^2+2p^4 is ?

Hi, i have the following equation:

(x/a)^m + (y/b)^n = 1

Problem: Find radius of curvature for the following two conditions:

Condition 1: x = 0; y = b
Condition 2: x = a; y = 0

Exponents m and n are greater than 0

Put in another way:

For the following curve:

y = (1-(x/a)^m)^n*b

1. What is the radius of curvature when x = 0?
2. What is the radius of curvature when x = a?

For example:

a = 200
b = 100
m = 2.5
n = 0.6

y = (1-(x/200)^2.5)^.6*100

x y
0 100
25 99.66817654
50 98.11310708
75 94.74034578
200 0


1. What is the rasius of curvature when x = 0?
1. What is the rasius of curvature when x = 100?

I am having problems with division by zero when using a standarg radius of curvature formula.

Thank you in advance,

How much water is used to fill a 3 feet deep pool in the shallow end and then slopes down to 9 feet deep. The length is 28 feet, the width is 18 feet, and the height is 9 feet. Also if you ask someone to paint the inside of the pool, how many square feet will they be painting?

In triangle ABC BC is the base and Angle A=30..If o Is the centre of circumcircle of ABC.....Show THat
BC is equal To radius of the circumcircle...

You have a rt triangle with the longer leg x+11, then an altitude or height drawn from the rt angle to the hypotenuse that forms 2 more triangles within the lg rt triangle and those 2 bases or legs are 23 and x. Solve for x.
