Step-by-step explanation:
s = -4.9t² + 49t
The vertex of the parabola is at t = -b/(2a).
t = -49 / (2 × -4.9)
t = 5
The rocket reaches its maximum height after 5 seconds.
Answer:

Step-by-step explanation:
If I can read the #'s correctly:
add the yes answers together 23+147 = 170
add the no answers together 112+48= 160
so your ratio of haves to have nots is 170 to 160
but both sides can be divided by 10, so it can be simplified to 17 to 16.
Good Luck!

10. 543 (10 more) gives 553. You can find out the number that is 10 more when you add the regular number by 10, 543 + 10 = 553.
Hope this helped!

We are given with the coordinates of one of the points of a line which is
(1,2)
In order to generate an equation of a line, we need at least one other point or the slope of the line. If we are given with the slope of line, we can use the point slope form which is
y - y1 = m (x - x1)
substituting
y - 2 = m(x - 1)
