depth of water is proportional to time
d = k*t
<span>d = 7/2 * t </span>
<span>a) the point (2,28) represents the rate 28/8 </span>
b) 3.5 cm/sec
<span>c) the slope between (8, 28) and (6, 21) is 7/2 = 3.5</span>
A= 8.55 X 10/-5 and B= 8.55 x 10/6
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
