I need to see the rest to solve the k but I know that the direct is 50. is there any other part to it so I can solve it
Hence the value of the expression above are as listed below
<em>f(6+4) = 25</em>
<em>f(6)+f(4) = 20</em>
<em>f(6-4) = 1</em>
<em>f(6)-f(4) = 6</em>
<em>f(6*4) = 67</em>
<em>f(6)*f(4) = 91</em>
<h3>Functions and values</h3>
Given the expression below f(x) = 3x - 5
f(6+4) = f(10) =3(10) - 5
f(6+4) = 25
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)+f(4) = 13+7
f(6)+f(4) = 20
f(6-4) = f(2) =3(2) - 5
f(6-4) = 1
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)-f(4) = 13-7
f(6)-f(4) = 6
f(6*4) = f(24) =3(24) - 5
f(6*4) = 67
f(6) = 3(6) - 5
f(6) = 18 - 5 = 13
f(4) = 3(4) - 5
f(4) = 7
f(6)*f(4) = 13*7
f(6)*f(4) = 91

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>
Yes, this series converges. We can check using the integral test; we have
