Answer
7 is the correct answer.
Step-by-step explanation:
4 x 3.5 = 14
14 divided 2 or 1/2 the base is 7
=[(sinx/cosx)/(1+1/cosx)] + [(1+1/cosx)/(sinx/cosx)]
=[(sinx/cosx)/(cosx+1/cosx)]+[(cosx+1/cosx)/(sinx/cosx)]
= [sinx/(cosx+1)] + [(cosx+1)/sinx]
= [sin^2x+(cosx+1)^2] / [sinx (cosx+1)]
= [2+2cosx] / [sinx(cosx+1)]
=[2(cosx+1)] / [sinx (cosx+1)]
= 2/sinx
= 2 cscx
(I think this will be helpful for you. if you can see the picture, it has more detail in it.)
X=1 -> y= -1/4
x=2 -> y= -2/3
x=3 -> y= -11/4
The way u write it in scientific notation is 600+50+2
