A third n minus 10 greater than twenty two
Answer:
t = .64sec and t = 1.56sec
Step-by-step explanation:
This is motion that is modeled by a parabola. The nature of a parabola is symmtrical about some vetical line. That means that if there is an x value where y = 3, for example, when the object is traveling upwards, it will come down after it reaches its max height and be at that same y = 3 height, just at a later time. By this, I mean that you will have 2 times where the height is 7. Besides that, this is a second degree polynomial, so we are expecting 2 values of t.
We are asked to find these 2 times when the height, h, is 7. So we will fill in a 7 for h and factor to solve for t:
To factor this quadratic, we need to get everything on one side of the equals sign and set it equal to 0:
Factor this however your teacher has instructed you to factor quadratics (my guess is that you're probably using the quadratic formula) to get t values of:
t = .64 sec and t = 1.56 sec
36/3 =12
Sorry there isn't much work to show, not sure what can be shown
In order to find the price per ticket, or unit rate, we need to divide 312 by 12
after this, we get 26. we know that unit rate is price PER 1 ticket.
Therefore, we get:
$26/ticket
