Answer:
hello your question is incomplete attached below is the complete question
answer : 54 m
Step-by-step explanation:
Applying jet equation of Parabola
(x-h)^2 = 4p (y-k) where (h,k) = 0
x^2 = 4py and this passes through ( 48, 24 )
(48)^2 = 4(p)(24)
hence P = 24
x^2 = 96h at x = 72 and y(h) unknown
= 72^2 = 96(h)
h = 72^2 / 96 = 54 m

Answer:
Option b
Step-by-step explanation:
The following system of linear equations is shown
These are two different slope lines.
We find the cut points of both lines with the axes.
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
...................................................................
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
The solution to this system will be a point for which it is fulfilled that:
In the image, different graphs with intersections are shown.
Locate among the options, one that shows the two lines of the system of equations according to their intersections with the x and y axes.
Option b is the only one that shows the graph of the lines
Then, The point of intersection of both lines in the graph is:
(-5, 13)
Therefore the solution of the system of equations is: (-5, 13)
You can verify this by replacing the point in the relationship
Equality is satisfied
Finally the answer is the option b
