Answer:

see explanation

Step-by-step explanation:

The function is increasing when the graph goes upwards from left to right.

The function is decreasing when the graph goes downwards from left to right.

Here the graph is decreasing from 3.23 to 3.25 and is decreasing the fastest from 3.23 to 3.24

Answer:

4g-124= -104, g-12= -7

Step-by-step explanation:

g=5

4g-124= ? g-12

4(5)-124 5-12

4(5)= 20 5-12= -7

20 - 124= -104

If the acceleration of an object is given by dv/dt = −2v, Find the position function s(t) if v(0) = 7 and s(0) = 0.

kirill [66]

Answer:

Step-by-step explanation:

Given that acceleration of an object is

$\frac{dv}{dt} =-2v\\\frac{dv}{v} =-2dt\\ln v = -2t+C\\$

is the solution to the differential equation

Since v(0) =7

we get ln 7 = C

Hence $lnv = -2t+ln 7\\v=7e^{-2t}$

since velocity is rate of change of distance s we have

$v=\frac{ds}{dt} =7e^{-2t}\\s= [tex]s(t) =\frac{-7}{2} (e^{-2t})+C)[$

substitute t=0 and s=0

$C=7/2$

So solution for distance is

$s(t) =\frac{-7}{2} (e^{-2t}-1)$
