Step-by-step explanation:
Answer: t = 3seconds
Step-by-step explanation:
To find the zero means we will equate the function to zero and then solve, that is
+ 32t + 48 = 0
by factorizing , we have
(t+1)(-16t+48) = 0
Therefore:
t = -1 or t = 3
since time can not be negative , then , t = 3 seconds
The answer is:
(null hypothesis) u=2.7; Ha(alt hypothesis): u<2.7
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
