Answer:
v = 39.2 m/s
Step-by-step explanation:
They gave you the equation for velocity during freefall in picture2 as:
v = 9.8t m/s
they ask you what the value of v (velocity) is after t=4 sec.
Just plug in t=4 into the equation.
v = 9.8t
v = 9.8(4)
v = 39.2 m/s
Okay so your slope is going to be -9 because that is the rise over run for that equation. 5 is you y-intercept.
<h2>
Answer:</h2>
The quadratic function are:
option: A A) y(y + 4) - y = 6
Option: C C.) 4b(b) = 0
<h2>
Step-by-step explanation:</h2>
We know that the general equation of a quadratic equation in terms of a variable x is given by:

A)
y(y + 4) - y = 6
On simplifying the terms we have:

Hence, option: A is correct.
B)
(3x + 2) + (6x - 1) = 0

Hence, it is a linear equation.
Hence, option: B is incorrect.
C)
4b(b) = 0
it could also be written as:

Hence, it is a quadratic equation.
Hence, option: C is correct.
D)
3a - 7 = 2(7a - 3)

which is again a linear equation.
Hence, option: D is incorrect.
