Answer:
d = Sqrt 41 = 6.4
Step-by-step explanation:
d = sqrt [(x-x)^2 + (y-y)^2]
d = sqrt [(-7 - - 2)^2 + (7-3)^2]
d = sqrt[(-7+2)^2 + (4)^2]
d = sqrt [(-5)^2 + (4)^2]
d= sqrt (25 + 16)
d = sqrt 41 = 6.4
Answer:
160,000
Step-by-step explanation:
Estimations like this usually involve rounding to easy numbers to multiply. You could do this in a number of ways depending on your ability to keep track of factors in your head, but the easiest way (and what I assume your teacher is looking for) is to round to the nearest, largest-power-of-ten, which in this case is the hundreds. 786 is closest to 800, and 217 is closest to 200, and 200*800 is 160,000. No calculator required is the key. You can also be slightly more sure that this is <em>reasonable</em> because you rounded up for one and down for the other, approximately by the same amount, too.
