Answer:
write one what I don't get it
Answer:
I believe it is 252 correct me if I'm wrong
- 16t^2 +144 you can rewriting in this form 144 -16t^2 = (12 -4t)(12+4t)
12-4t=0
12 =4t divide both sides by 4
t=3
hope helped
<em><u>Explanation</u></em><em> </em><em>:</em>
The line DF is parallel to OB, therefore Angle x = Angle y.
( because, they for corresponding angle pair which are equal. )
And the angle made by an arc at center is always double the angle made by the same arc at its boundary, hence
D, Each x value has one and only one y value.; This is because if an x-value repeats itself then it is not a function. You can test this on a graph by drawing a vertical line on it. If the vertical line intercepts the line more than once anywhere on the graph, then it is not a function.
