Question

help please?


1. If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?
2.xy = −16. What is the constant of variation for this relationship?
3.V varies inversely with T and V = 18 when T = 3. Which equation shows this relationship?

Answer 1

solving #1, y=k/x

Answer 2

so, I=k/R

Answer 3

.25=k/18... solve for k

Answer 4

so its .25 = 4.5/18?

Answer 5

yes! :)

Answer 6

and #2, I think that the constant of variation would be the only constant in the equation... -16

Answer 7

and, so you know what to do with # 3 now, right? y=k/x, V=k/T

Answer 8

yeah so for #2 thats the answer

Answer 9

i mean 1 sorry

Answer 10

18=k/3, and solve for k :)

Answer 11

yep :) great job! you got it :)

Answer 12

thanks!!! again :) haha

Answer 13

yvw :)
