D) There is no association between commuting preferences and gender.
Answer:
16 is Potential energy and 411.6 Joules, 17 is Kinetic energy 896,000
Step-by-step explanation:
PE=mgh
2 kg(9.8m/sec^2) 21m= 411.6J
KE=1/2mv^2= 1/2(1120kg)(40m/s)^2= 896,000J
There are a total of 16 coins, so out of the ratio, that 16 goes on the bottom. Now you have to add up the coins that are NOT quarters and that number goes on the top. So your ratio is 8/16 or 1/2
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.
f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
