Question

Write the equation for the line tangent to the circle x^2 + y^2 = 29 at the point (2, 5).

Answer 1

do you have your derivative?

Answer 2

this is all i'm given

Answer 3

do you know how to calculate the derivative implicitly?

Answer 4

no..

Answer 5

find equation of radius

Answer 6

i'm sorry... is this a calculus problem?

Answer 7

then use it's slope to find equation of tangent

Answer 8

its algebra 2b. I don't believe its calculus

Answer 9

then @jit4won , has the right approach... sorry..

Answer 10

thanks

Answer 11

equation of radius = 5x-2y= 0

Answer 12

equation of tangent = 2x+5y =29

Answer 13

Anything else that I may help you with ?

Answer 14

Actually, yeah!!
Write an equation in standard form for the hyperbola with vertex (4, 0), and focus (10, 0).

Answer 15

focus =(a.0) =10,0
a= 10

Answer 16

sorry vertex = a,0

Answer 17

I'm told the answer is supposed to be in the form of a fractional equation

Answer 18

yes

Answer 19

I'm lost

Answer 20

1 min

Answer 21

vertex = 4,0
a= 4
focus = 10.0
c= 10
c^2 = a^2 +b^2
b^2= 10^2-4^2= 84
equation =
x^/16 -y^2/84 = 1

Answer 22

awesome!
