<u>In radian format</u>:
Length of arc =
..........where x is the angle and r is radius.
Here the length of arc is 14 inches and radius given 9 inches
using the formula:
rads
Answer:
1) 5/7
2) (21, 5)
Step-by-step explanation:
1) The slope of the line passing through the points (7, 5) and (21, 15) is
![\frac{15-5}{21-7} =\frac{10}{14}=\frac{5}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B15-5%7D%7B21-7%7D%20%3D%5Cfrac%7B10%7D%7B14%7D%3D%5Cfrac%7B5%7D%7B7%7D)
because slope is (difference of y)/(difference of x)
the first option is correct
2) 1/3 of 5/7 is 5/21.
The line will be in the form of
y = 5/21 x + b where b is the y-intercept.
Find the complete equation by plugging in (0,0) since it passes thorugh the origin.
0 = 5/21 (0) +b
0=0+b
b=0
The equation: y=5/21 x
let's check each option by plugging in.
y= 5/21 (3)= 5/7
y is not 5 but 5/7
y= 5/21 (3)= 5/7
y is not 7 but 5/7
y= 5/21 (21) = 5
y is 5, which matches with the answer choice!!!
y= 5/21 (21) = 5
y is 5, not 7.
The third option is correct
