f(3) = 5 g(3) = 16
f(3) + g(3) = 21
The exterior angles add to 360
the interior and exterior angles add to 180 so exterior angle is 60
360 / 60 = 6 sides
8 laps x 1/4 mi/lap = 2 miles
2 miles = 3219 meters
18 minutes = 1080 s
3219 m / 1080 s = ~~ 2.98 m/s
I believe the answer is 1

Acceleration IS the slope of the velocity graph
Acceleration IS a vector
Accelration is m/s^2 NOT m/s
VELICITY is change in displacement/change in time
Assuming her billing cycle starts on the 1st of the month
(20 days x $4805 + 11 days ($4805 + $300) ) / 31 days = $ 4911.45
We want miles per hour or miles/hr
20 minutes = 1/3 hour
2.5 miles /(1/3 hour) = 7.5 miles/hr
30kx-6kx=8
24 kx = 8 divide both sides by 24 k
x = 8/(24k) = 1/(3k)
Take the two points ....slope = rise/run = (y1-y2) / (x1-x2)
= (8- -4) / (-1-2) = 12/ -3 = -4
