Answer:
8.1 inches
Step-by-step explanation:
Proportion of angle to the whole circle:
(13π/18)/2π=13/36
13/36=18.4/2rπ
13/36=9.2/rπ
13rπ=331.2
rπ=25.47
r=8.1
65% of 1 = .65
65/100 = 13/20
65/100 = .65
65/100 = .65¢
Answer :
y = 5/2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5/2 , thus
y = 5/2x + c ← is the partial equation
To find c substitute (2, 0) into the partial equation
0 = 5 + c ⇒ c = 0 - 5
y = 5/2x - 5 ← equation of line
