Step-by-step explanation:
We want to reflect this 2x1 vector on the line y = x.
To make this reflection we must use the following matrix:
Where R is known as the reflection matrix on the line x = y
Now perform the product of the vector <-1,5> x R.
The vector matrix that represents the reflection of the vector <-1,5> across the line x = y is:
Answer:
"The product of a rational number and an irrational number is SOMETIMES irrational." If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational
A better statement would be:
"The product of a non-zero rational number and an irrational number is irrational
5 m/sec or 300m / min
using speed =
change 5 min 20 sec to seconds = (5 × 60) + 20 = 320 sec
speed = = 5m / second or
speed = 60 × 5 = 300m / minute
