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
Answer:
I think it is 26%
Step-by-step 124 divided by 479
If Morgan drinks 4 glasses of 12 ounces of water, then she drinks 48 fluid ounces throughout the day. There are 16 ounces in one pint. That means, Morgan drinks 3 pints of water!
Learn this :
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number
ok....so u need the equation for a vertical line passing thru (-5,-1)...
a vertical line is represented by x = a number.....and that number will be the x value of ur points.
Therefore, ur equation is : x = -5 <==
**just so u know, if u were needing a horizontal line going thru the same points, ...and a horizontal line is represented by y = a number...with the number being the y value of ur points....the equation would be y = -1
Answer:
10
Step-by-step explanation:
If W is the present age of the woman and D is the present age of the daughter, then:
W = 4D
W + 5 = 3(D + 5)
Substituting the first equation into the second:
4D + 5 = 3(D + 5)
4D + 5 = 3D + 15
D = 10
The daughter is 10 years old.
