A pack of 100 wolves on a remote island are suffering from a new disease. Let W(t) be the number of sick wolves at time t. Suppo

se that 10 wolves are sick initially and the disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves. Give the mathematical model (IVP) for W.
a) dWdt=kW,W(0)=b) dWdt=ktW−−√,W(0)=10
c) dWdt=kW−−√,W(0)=10
d) dWdt=kW,W(0)=100
e) dWdt=kW−−√,W(0)=100
f) None of the above.

Answer:

b)\,\frac{dW}{dt}=kt\sqrt{W}, \,W(0)=10

Step-by-step explanation:

Initial number of sick wolves = W(0) = 10

At time t, no. of sick wolves = W(t)

Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:

\frac{dW}{dt}=kt\sqrt{W}

Mathematical model of above case is:

\frac{dW}{dt}=kt\sqrt{W}, \,W(0)=10

A crew must repave a road that is 3/8 miles long. They can repave 1/48 miles per hour. How long will it take the crew to repave
Anika [276]

Answer:

Step-by-step explanation:

3/8 miles long, 1/48 miles per hour

3/8 and 1/48 can have a common denominator, so you make 3/8 into 18/48 by multiplying both the numerator and denmoinator by 6.

18/48 miles long

1/48 per hour

divide: 18/48 divided by 1/48, which turns into 18/48 x 48/1 which equals 18

18 hours
