Correct answer is the last one.
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
That comes to 225.65 / 6.25
= 36.1 hours
First, let's take a look at the formula to figure this out.
m = y2 - y1/x2 - x1
y2 would be -5, and y1 would be 8. -5 - 8 = -13.
x2 is -6, and x1 is also -6. -6 - -6 would be -12.
So, now we must divide -13 and -12, which results in 1 1/12.
The Answer Is Acute
The angle hasn't reached the point of a right angle (90°), which makes it a acute angle.
