Answer:
Step-by-step explanation:
<u>Linear Momentum
</u>
The momentum of a system of masses m1,m2,m3... with speeds v1,v2,v3,... is given by
When some interactions take place into the system of masses with no external forces interferring, the total momentum is not changed, which means that if the new speeds are v1', v2', v3'... then:
The problem relates the story of Batman (m1=100kg) who is initially assumed at rest and lands on a boat with mass m2=580 kg initially moving at 14 m/s to the positive reference. When the collision takes place, both masses join and a common speed 
is achieved by the common mass. Applying the conservation of momentum, we have
Since 
Solving for
First set up a system of equations and solve.
4x+y=10
x+3y=8
In order to have one variable cancel out, I will multiply the top by -3.
-12x-3y=-30
x+3y=8
____________
-11x=-22
x=2
Then plug the x value into one of the original equations.
(2)+3y=8
3y=6
y=2
Now plug both into the final equation:
5(2)+8(2)/3
(10+16)/3
26/3
8.667 is the answer or 26/3.
For Part A, the answer would be 59%. You would just be adding 70 and 48 to get 118, then divide by 200 (the total amount of students). For Part B, the answer would be 51%. You would just add the total amount of girls and divide by the total amount of students, which is 102/200.

Answer:
Step-by-step explanation:
<u>First year salary</u>
<u>Annual pay rise</u>
<u>Functional relationship</u>
<em>It is going to be an exponential function as every year salary will increase 1.03 times</em>
- s(x) = 55000*1.03^x, where s- salary and x- number of employment years
