Answer:
A) +5000
Step-by-step explanation:
I'm not sure of my answer but
hope that help
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:
Slope = 6
Step-by-step explanation:
Find the difference of the y's over/divided by the difference of the x's.
i.e 8-2 / 14 - 13 = 6 / 1 = 6
