Step-by-step explanation:
Selection C is appropriate.
Probably, the function only usefully describes the height between the time it is thrown (x=0) and the time it lands (x=5).
_____
Conceivably, a function can be written that would describe height before it is thrown and after it hits the ground (as after it bounces, for example). In that case, one might be interested for the domain of "all real numbers" or at least "all real numbers representing the time during which the object was in existence."
<u>Given</u>:
Four lines are marked proportion, the length of TW can be determined by
<u>Value of a:</u>
Let us set the proportion for the given lines.
Thus, we have;
Thus, the value of a is 5.6
<u>Value of b:</u>
Let us set the proportion for the given lines.
Thus, we have;
Thus, the value of b is 5.
<u>Length of TW:</u>
The length of TW is given by
Thus, the length of TW is 13.6
5x-2(2x+3)=-6
-2*2x=-4x
-2*3=-6
5x-4x-6=-6
5x-4x=x
x-6=-6
x=6-6
x=0
Replace x with 0 in one of the above equations
y=2(0)+3
2*0=0
y=0+3
y=3
Answers
x=0
y=3
