Answer:
Go to the left nine Units and go up two units
Step-by-step explanation:
Hello :
cscx = -5/2
1/sinx =-5/2
sinx=-2/5
sin²x+cos²x=1
4/25+cos²x=25/25
cos²x = 21/25
between 270 and 360 : cosx > 0 cosx=(<span>√21)/5
but : sin2x =2sinx cosx
sin2x = 2(-2/5)(</span>(√21)/5)
sin2x = (-4√21)/25
Answer: There would be about 6 or 7 silk fibers per 300 yard length of silk fiber.
The problem states that each thread is made of about 3 to 10 silk fibers. The the problem as for a reasonable estimation of the number of silk fibers. It would be safe to assume that a reasonable estimation would be the average (or mean) of 3 to 10.
(3 + 10) / 2 = 6.5
Since 6.5 is the average, we could use 6 or 7 as a reasonable estimation.

yes is a linear line because linear mean a straight line
b represents rate of change
