Answer:
(1.35, 1.6)
Step-by-step explanation:
A screenshot of the graph is attached.
Once we graph the equations
and
, the solution to this system will be their intersection point.
Tracing the graph on the calculator, we see that the point of intersection is at about (1.35, 1.6).
He will reach the ground after 2.023 seconds.
To start, write a quadratic equation in vertex form with the given information about the vertex.

All that we need to solve for is a. Plug in the point (0, 9) and you will be able to solve for a and write the complete equation.
Now, just use the quadratic formula and you will get 2.023 seconds for when he hits the ground.
For the earth the differences are 3.4 miles different. on mars they are 11 miles apart.
Answer:
Triangle inequality rule states that the sum of eachpair of sides must be greater than the third sides.
240 + 123 > 207 true
240 + 207 > 123 true
123 + 207 > 240 true
A = √(s(s-a)(s-b)(s-c))
s is the semi-perimeter (a + b + c)/2
s = (240 + 123 + 207)/2
s = 285
A = √(285*(285-249)(285-123)(285-207))
A = 12,730 units^2
