sorry I have that much qualifications to work on this question and hoping this much will make bit easy for you to solve it further
Answer:
Here we have the function:
S(t) = 500 - 400*t^(-1)
Then the rate of change at the value t, will be:
S'(t) = dS(t)/dt
This differentiation will be:
S'(t) = -400/t^2
Then:
a) the rate of change at t = 1 is:
S'(1) = -400/1^2 = -400
The rate of change after one year is -400
b) t = 10
S'(10) = -400/10^2 = -400/100 = -4
The rate of change after 10 years is -4, it reduced as the years passed, as expected.
Answer:
4.86 people/sq.miles
Step-by-step explanation:
the area of the state of Wyoming =
360 × 280 = 100,800 sq. miles
so, the population density =
490,408 ÷ 100,800
= 4.86 people/sq.miles
300% is the equivalent of * 3, so, 1.5 x 3 = 4.5. She would sell her bracelets at $4.50.
