Answer:
0.5 in the first box and 1 or -1 in the second
Answer: The ball hits the ground at 5 s
Step-by-step explanation:
The question seems incomplete and there is not enough data. However, we can work with the following function to understand this problem:
(1)
Where
models the height of the ball in meters and
the time.
Now, let's find the time
when the ball Sara kicked hits the ground (this is when
):
(2)
Rearranging the equation:
(3)
Dividing both sides of the equation by
:
(4)
This quadratic equation can be written in the form
, and can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving we have the following result:
This means the ball hit the ground 5 seconds after it was kicked by Sara.
Answer:
i did't see the value I in the equation

Answer:
The standard form of line is

Step-by-step explanation:
we are given a line
slope=3
so,

y-intercept of -2
so,

now, we can use slope-intercept form of line

now, we can plug values

we can write it in standard form of line


we can subtract both sides by 3x



So, the standard form of line is
