Answer:
31.9 inches.
Step-by-step explanation:
A Frisbee has a diameter which measures 10.2 inches.
The greatest possible error is 0.05 because the measurement was made to the nearest tenth.
So, the diameter is =
radius = = 5.075
Circumference is given as:
=
= 31.87 rounding to nearest tenth as 31.9 inches.
The minimum circumference of the Frisbee to the nearest tenth is 31.9 inches.

Answer:
Θ = 157.7°
Step-by-step explanation:
Given
cosΘ = - 0.925
Since cosΘ < 0 then Θ is in the second or third quadrant.
Since 0° ≤ Θ ≤ 180° then Θ is in the second quadrant. thus
Θ = (- 0.925) = 157.7° ← angle in second quadrant

1) Pick 2 points on the line (i chose (-4,3) and (3,-4)
2) Find slope of the line using the 2 points. (work below)
3) Find y-intercept, which is the point where y-axis and the line cross (y-intercept is -1).
4) Place both slope and y-intercept into slope-intercept form, y=mx+b (m=slope and b=y-intercept.)
5) Change y to f(x) (meaning function of x).
Work:
3-(-4)/-4-3=3+4/-4-3=7/-7=-1
y-intercept equals -1 also.
y=mx+b
y=-1x+(-1)
y=-1x-1
