To find the cost of 1 water bottle you divide 60 degrees into 75 (75/60) which gives you 1.25 degrees for each water bottle. To find 120 water bottles temperature multiply the 1.25 degrees for 1 water bottle times 120 (120x1.25). 120x1.25=150 The answer would be 150degrees
5 is an integer but 2/3 is not an integer
Since the percent lost per hour is constant, this is a linear equation, and the slope-intercept form of a linear equation is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where <em>m</em> is the slope and <em>b</em> is the intercept.
In this case, we want to formulate how much percentage is left based on how many hours have passed, so the percent left is dependent upon the time passed. This means that the dependent quantity is the percent of battery life left, and this will be variable <em>y</em>.
Volume of a cylinder = pi r^2 h where r = radius of the base and h = the height.
so if we are given a radius of 2 cm and a volume of 180 cm^3 we work out the height as follows:-
180 = pi * 2^2 * h
h = 180 / (pi*2^2)
height h = 180 / 4pi = 14.32 cm to nearest hundredth
The equation is
P = 200 / (1 + 20000 e^-0.549t)
TO get the rate of epidemic growth, we differentiate the equation with respect to t
dP/dt = -200(1 + 2000 e^-0.549t)^-2 (20000)(-0.549)
Substitute t = 10 and you will get the epidemic growth rate after 10 years
