First you need to convert the fraction to a decimal which would be .7. then you divide 4.1 to .7 and you will get 5.86
It changed 1/2 a mile every hour (60 minutes) So it will take 3 hours (180 minutes) to reach the ground level.
........300
600.......600
........300
So (300(2))+(600(2))=1800 meters of fencing
Answer:
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
Formula :
Substitute the actual values of the points into the distance formula.
Answer:
The lines ared skew
Step-by-step explanation:
First we check if they are parallel. To do this we compare the ratios of the slopes of each component, and this should be the same:
As we can see the ratios are different so they are not parallel lines.
Now we test for intersesction:
we have to equate each component and solve it as a system:
- 3-2t=-1-u
- 7+4t=18+3u
- -3+8t=7+2u
From equation 1: u=2t-4 we replace this in eq. 2
From equation 2: t=1/2 replacing both in equation 3 should give us an identity
From equation 3: we reach 1=3 as this is not true, out hypothesis that the lines intersect is wrong.
Since this lines are not paralel and don't intersect we must conclude that the are skew
