Answer:
50km
Step-by-step explanation:
Explanation:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by 2.51. Then, 20 x 2.5=50. So the answer is 50 km
Each piece of this function is continuous on its respective domain (because all polynomials are continuous functions), meaning
• 2 - x exists for all x < -1
• x exists for all -1 ≤ x < 1
• (x - 1)² exists for all x ≥ 1
So this really just leaves the points where the pieces are split up, i.e. x = -1 and x = 1. At both of these points, the two-sided limit exists as long as the one-side limits from both sides exist and are equal to one another.
At x = -1, as I said in my comment, you have
while
But -1 ≠ 3, so the two-sided limit
does not exist. So a = -1 is one of the points you would list.
At x = 1, we have
while
and again the one-sided limits don't match, so this two-sided limit also does not exist, making a = 1 the other answer.
C. velocity includes the direction of travel whereas speed does not.
