Answer: Paula starts with 301.5 yarns.
Step-by-step explanation:
Equation of a line passing through two points (a,b) and (c,d) is given by:-

Given: x= number of square inches knitted on the scarf
y= number of yarns remaining on the ball of yarn
The equation of a line passing through (15, 300.2) and (26, 177.88):

To find initial point, put x=0

Hence, Paula starts with 301.5 yarns.
Answer:
Step-by-step explanation:
this is a 45-45-90 triangle. The angle opposite the 45° angle is also 45°.
HI = HJ because this is an isosceles triangle.
Use the cos function to find the length of HJ:
cos Ф = adj / hyp or adj = (hyp)(cos Ф).
1
Here we have adj = HI = HJ = 4√5 cos 45° = 4√5 · -----
√2, or 4√5 / √2
4√10
This last result simplifies to ----------
2
or 2√10 (answer)
The length of side HJ and that of HI is 2/√10.
