Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let
. Its vertex can be found on the coordinates
such that
and
, in which
.
Using the coefficients given by the question, we get that:

Thus, we have:

So the statement is true, because the
coordinate of the vertex of the function is equal to 
660sec in 3 days.
So 220sec per days
220•5= 1100
1100sec = 18min and 30 second.
Ans:
18min and 30 sec
Answer:
x=4
Step-by-step explanation:
5x-4=16
5x-4+4=16+4 add 4 to each side
5x=20 simplify
5x/5=20/5 divide each side by 5
x=4 simplify
84 units tall. If one inch is 12 units then seven inches is 84 units.
