Answer:
A. The football does not reach a height of 15ft
Step-by-step explanation:
Given
Required
Determine which of the options is true
The option illustrates the height reached by the ball.
To solve this, we make use of maximum of a function
For a function f(x)
Such that:
:
i.e we first solve for
Then substitute for x in
In our case:
First we need to solve
Then substitute for t in
By comparison:
Substitute for t in
This implies that the maximum height reached is 14.0625ft.
So, the option that answers the question is A because
Make the equation the same or a multiple of the other to have an infinite number of solutions. See how the -8/2= -4 and 6/2=3 ? then -2/2 = c
Make c = -1 and they are the same linear equation. (same slope, same intercepts, same line) and therefore have infinite solutions.
In order to have no solutions, the lines cannot cross at all and so they must be parallel but not the same line. Parallel lines have the same slope with different intercepts. if you rearrange both equations in slope intercept form:
y = x/3 - 4/3
y = - cx/3 - 4/3
no matter what you make c the lines will always cross at the y-intercept (0, -4/3). this is a solution and therefore there's no value of c that would produce a system with no solution.
Answer:
do you need it to be simplified?
I think y=0 because 6 multiple by 0 is 0 then x= 6 hope this helps might want to check my work to
I would like to have a patient and good teacher,who is not angry or stressed,or give us lots of homeworks.
Hope I helped u :)
