The train will take 16 seconds to pass <em>completely</em> through a 300 meter tunnel.
Let suppose that the train moves itself at <em>constant</em> velocity, the vehicles needs to cover the tunnel length () and its length (), both in meters, to pass through the tunnel, the time taken by the train () is described by the following kinematic formula:
(1)
Where is the train velocity, in meters per second.
If we know that , and , then the time taken by the train is:

Density
is given by
where m is the mass of the object
V is the Volume of the object
let m1 be the mass of the smaller cube
let m2 be the mass of the larger cube
you know that the larger cube has twice the mass of the smaller cube
or m2=2*m1
so apply this information into the density equation and you can determine the volume of the larger cube
Well from what i know here's what i would put........
-4 * -2 = 8 - 2 = 6
-4 * -1 = 4 - 2 = 2
-4 * 0 = 0 - 2 = -2
so it does represent a function......I really hope that helped!!
Answer:
Step-by-step explanation:
Given that a county park system rates its 20 golf courses in increasing
order of difficulty as bronze, silver, or gold.There are only two gold courses and twice as many bronze as silver courses.
Hence we get there are 2 gold, 12 bronze and 6 silver courses.
A) If a golfer decides to play a round at a silver or gold
= He can select any one of gold or silver
= (2+6)C1 = 8 ways
B) f a golfer decides to play one round per week for 3 weeks,first on a bronze course,then silver,then gold,
=Here no of ways = 2x12x6 = 144
(Because he can play any one of two gold, any one of 12 bronze...)
(Assuming every week all games are available)
Slope = 1/2 y-intercept = 5/3 so y=1/2x+5/3
