3. Suppose the velocity, v, of an object is given by
v=2t² -5t-12
where t is time in seconds. Find the intervals where
the velocity is positive.

4

Step-by-step explanation:

Using,

Where,

A= 2

B= -5

C= -12

By substitution, you get,

By doing the calculation you get,

Find the solution of both,

AND

t= 4 seconds OR (t= -1.5 seconds, NP)

So t=4

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.
