Answer:
D, C
Step-by-step explanation:
for part a, there is a negative slope with the graph shifted two units upwards
for part b, if you plug in C, you get an answer that works
Step-by-step explanation:
given 30°
converting into radian measure
= 30 * π / 180
= π / 6
Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
The answer is B.
When you set up a ratio of all the corresponding sides, the ratios all equal 2:1
