What is the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4?

ruslelena [56]

X) = 3 ln(x)

g(x=2) = 3 ln(2)
g(x=4) = 3 ln(4) = 3 ln(22) = 6 ln2

We have two ordered pairs:

(x,3 ln(2)) and (4,6 ln(2))

The average rate of change is the slope (m) of the secant line connecting the two points:

m = (6 ln2 - 3 ln2)/(4-2) = 3ln(2)/2 ≅ 1.04

Fudgin [204]

5/8-5/12(3-1/4)+2/3=5/8- 5/12 * (12/4-1/4)+2/3=
5/8- 5/12 * (11/4) +2/3=
5/8- 55/48 + 2/3=
30/48 - 55/48 + 32/48=

For the differential equation dy/dt=ky, k is a constant, y(0)=24, and y(1)=18. What is the value of k?

Gre4nikov [31]

The equation is separable, so solving it is trivial:

$\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt$
