The angle required will be given by:
x=52/5π-5*2π=2/5π
the positive angle less than one revolution around the unit circle that os co-terminal with angle of 52/5π is 2/5π
3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
Dt = 2(0.8)t = 1.6t = 1.6(10) - 1.6(5) = <span>8 m/s</span>
2 brown, 8 yellow, 8 green, thus our sample space is 2+8+8 = 18.
What is the probability that the card is NOT yellow? How many non-yellow are there? well 2 + 8 = 10, favorable outcomes.
divide total miles by total time:
60.9 / 3.5 = 17.4 miles per hour
