it's C, assuming x always has the same value
It should be C
Have a good day!!
SSS is side side side so all the sides have to be congruent for the triangles to be congruent.
SSA is side side angle so two sides and an angle needs to be congruent for the triangles to be congruent.
SAS is side angle side so two sides and an included triangle need to be congruent for the triangles to be congruent.
Hope that helps:)
Answer:
Y x 3 - 3 = Y + 57
30 would be your answer
add 3 to both sides so it becomes Y x 3 = Y + 60 and 60/2=30
30 x 3 = 90-3=87
30 + 57 = 87
Hope this helps (I am twelve and I know how to do this)
Step-by-step explanation:
Answer: 3 seconds
We are given the following function:
(1)
Where:
is the time the ball is in the air
the initial upward velocity
the initial height of the ball
is the final height of the ball. If no one catches it, this will be <u>zero</u>
So, equation (1) changes to:
(2)
Substituting the known values:
(3)
This is a quadratic equation in the form
. In order to find
we can use the quadratic formula for the roots:
(4)
Where
,
and 
Substituting this values in (4):
(5)
(6)
(7)
For
:
(8)>>>> This result does not work for us because is negative
For
:
(9)>>>This is the result
Therefore:
<h2> If no one catches the ball, it will be 3 s in the air</h2>
