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

won't that be plagrisim thought?

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
