Answer:
B
Step-by-step explanation:
Here, we want to select an option that represents y as a function of x
We simply want to select an option which is a function
Now, the answer in this case is one in which there are no repeating values of x and y
What this means is that all x values and all y values exactly have a single relationship between each of them
No y values has two x values and no x values links to 2 y-values
With this in mind, the correct answer is ;
option B
Answer:
(y-5)(y+3)
Step-by-step explanation:
im assuming that the y2 meant y^2 :,33
The equation of the ravine function is an illustration of a quadratic function
It will take 1.5 seconds for the music player to fall to the bottom of the ravine
<h3>How to determine the time the music player will fall to the bottom?</h3>
The equation of the function is given as:
Take the square of both sides
t^2 = (8t + 24)/16
Multiply both sides by 16
16t^2 = 8t + 24
Divide through by 8
2t^2 = t + 3
Set the equation to 0
2t^2 - t - 3 = 0
Expand the equation
2t^2 + 2t- 3t - 3 = 0
Factorize the equation to 0
2t(t + 1)- 3(t + 1) = 0
Factor out t + 1
2t- 3)(t + 1) = 0
Expand
2t- 3 = 0\ or\ t + 1 = 0
Solve for t
t= 1.5\ or\ t =- 1
Time cannot be negative.
So, we have:
t= 1.5
Hence, it will take 1.5 seconds for the music player to fall to the bottom of the ravine
