Crude birth rate is all the time reported per 1000 living
people.
To compute for this, the formula is number of births x 1000
divided by the estimated population at midyear. So plugging in the values
given:
14,662 x 1000 divided by 994,948
= 14662000 / 994948
= 14.68 per 1000 living people.

Partial derivative is derivative over only 1 variable.
here we have 2 variables so it depends on which variable you want to make partial derivative.
case 1.
df/dx = -3y
case 2
df/dy = 5y^4 - 3x
Answer: 1.5 meters
Step-by-step explanation:
Given: A lake near the Arctic Circle is covered by a sheet of ice during the cold winter months. S
S(t) models the ice sheet's thickness (in meters) as a function of time t (in weeks) 
if we put x=0, then

So 4 meters is the initial thickness
To find the thickness after 6 weeks, put x=6 we get

Decrease in thickness every 6 weeks=
