Answer: magnitude ab = 9.06
Step-by-step explanation:
The vector coordinates will be represented with ( X , Y )
Magnitude of ab will be
ab^2 = (X2 -X1)^2 + (Y2 -Y1)^2
ab^2 = (2 -1)^2 + (-3 -6)^2
ab^2 = 1^2 + 9^2
ab^2 = 1 + 81
ab = 9.06
Answer:
What are we rounding?
Step-by-step explanation:
Try y=-2x-3 (I think that should be it)
- you will need 2 busses to only transport the boys.
- Mark is at (1 + 5/6) miles of his house.
<h3>How many buses would it take to carry only the boys?</h3>
We know that there are (3 + 1/2) groups, such that each group fill one bus.
2/5 of the students are boys, then the number of groups that we can make only with boys is:
(2/5)*(3 + 1/2) = 6/5 + 1/5 = 7/5 = 5/5 + 2/5 = 1 + 2/5
Then you can make one and a little less than a half of a group, which means that you need 1 and 2/5 of a buss to transport the boys, rounding that to the a whole number, you will need 2 busses to only transport the boys.
<h3>How far is Mark from his house?</h3>
The original distance is:
D = (2 + 3/4) miles.
But Mark only covers 2/3 of that distance, then we have:
d = (2/3)*D = (2/3)*(2 + 3/4) miles = (4/3 + 2/4) miles
d = (4/3 + 1/2) miles = (8/6 + 3/6) miles = (1 + 5/6) miles
Mark is at (1 + 5/6) miles of his house.
