4.) To find the distance between (17, 3) and (17, −5), Marcia used the following equation. Is Marcia correct? Explain. WILL MARK BRAINLIEST FOR RIGHT ANSWER '
D = | 3 − (−5) | = 8
a.) Marcia is not correct. Since the points are in two-dimensions, the distance formula must be used to find the distance.
b.)Marcia is correct. For any pair of points, the distance between the points can be treated as if they are in one-dimension.
c.)Marcia is correct. Since the x-coordinates are the same, the distance between the points can be treated as if they are in one-dimension.
d.)Marcia is not correct. According to the distance formula, the distance should be D=√(17-17)^2+(3-(-5))^2=√8

Answer:

C

Step-by-step explanation:

3-(-5=8

3+5=8

They are on the same x axis so all you have to do is add 3 and 5 together.

Answer:

c) Marcia is correct. Since the x-coordinates are the same, the distance between the points can be treated as if they are in one-dimension.

Step-by-step explanation:

a) Marcia is not correct. Since the points are in two-dimensions, the distance formula must be used to find the distance.

  • No, in this case x-coordinates are same and this can be treated same as number line

b) Marcia is correct. For any pair of points, the distance between the points can be treated as if they are in one-dimension.

  • No, it is not the case for any pair of points

c) Marcia is correct. Since the x-coordinates are the same, the distance between the points can be treated as if they are in one-dimension.

  • Yes, in this case x-coordinates are same (17)

d) Marcia is not correct. According to the distance formula, the distance should be D=√(17-17)^2+(3-(-5))^2=√8

  • No, formula is correct but the answer is incorrect
