Answer with Step-by-step explanation:
We are given that
u+ v and u-v are orthogonal
We have to prove that u and v must have the same length.
When two vector a and b are orthogonal then
By using the property
We know that
Magnitude is always positive
When power of base on both sides are equal then base will be equal
Therefore,
Hence, the length of vectors u and v must have the same length.
4/5(8)= 32/40
5/8(5)= 25/40
You have to get the same denominator to be able to subtract so multiply one fractions denominator by the other so it becomes the same, and vise versa.
32/40-25/40= 7/40 which cannot be simplified.
Answer= 7/40 greater than the width.
Answer: 9 cars.
Step-by-step explanation:
given data:
average length of a car = 16feet
speed of the driver = 100miles/hr
Solution:
First we would need to convert the Speed of the car from miles/hr to Feet/secs.
To do this we know that 1mile/hr = 1.467 feet/secs
= 100m/hr * 1.467
= 146.7Feet/secs.
So now the number of cars between him would be
= 146.7Feet/secs / 16
= 9.17
approximately there should be 9 cars between you.
