Answer 3

help please!

Answer 4

\[\tan x + \sec x = 1\]
\[\frac{\sin x}{\cos x} + \frac{1}{\cos x} = 1\]
\[\frac{\sin x +1}{\cos x} = 1\]
\[\sin x +1 = \cos x\]
this only occurs when sin x = 0 or x=0

Answer 5

could i ask you one more question please?

Answer 6

sure

Answer 7

why does a calculator return an error when trying to find inverse sine of 1.055? is it because sine cant be more than 1?

Answer 8

correct range of sine and cosine is [-1,1]

Answer 9

one more than im done. promise lol A high-altitude spherical weather balloon expands as it rises due to the drop in atmospheric pressure. Suppose that the radius r increases at the rate of 0.02in./sec and that r = 36in. at time t = 0; Determine an equation that models the volume v of the balloon at time t, and find the volume v of the balloon at time t, and find the volume when t = 360 sec

Answer 10

i got 4pi(36+0.02t)^3/3

Answer 11

you got it

Answer 12

okay thank you!
