45/5 = 9minutes/wall = 1wall/9minute/4 people = (1/36) per minute per person
(1/36)*6 = 1/6 wall per minute per 6 people * 24 = 4 walls in 24 minutes
24 Minutes total
Answer:
<u>Work Done = 27.66 Joules</u>
Step-by-step explanation:
The work done is:
Where
F is the fore
d is the distance moved
is the angle
The force is "4"
The distance is the distance from (1,7) to (8,10)
The distance is the square root of change in y coordinates, squared and sum of change in x coordinates, squared. Hence, distance is:
The angle is gotten by the formula:
So, now:
Work Done = 
<u>Work Done = 27.66 Joules</u>
Answer:
y= CC-4.5x^2
Step-by-step explanation:
To find the general solution to the differential equation
dy + 9x dx = 0, we employ the method of separating variable as follows:
Note: { will represent the integral sign here.
Separating the variables and integrating, we have
{dy = -{9x dx
y = -(9/2)(x^2) + CC,
where CC is the given constant of integration.
This can be rearranged/simplified to yield
y= CC-4.5x^2
