To solve this problem you must apply the proccedure shown below:
1. You must use the formula for calculate the area of a rectangle:
2. Now, you must solve for the width:
Therefore, the answer is:
Answer:
c
Step-by-step explanation:
If the dot product of the vectors is zero then they are perpendicular
(5, - 1) • (- 3, 6)
= (5 × - 3) + (- 1 × 6) = - 15 + (- 6) = - 15 - 6 = - 21 ≠ 0
Since product is not zero vectors are not perpendicular
Answer:
Step-by-step explanation:
Left hand side is a positive number. Right hand side is positive. The equation should have real roots. (worst case, the root would be complex, but let's not open that can of worm)
Let's start noticing that and then take the square root of both sides, remembering that we need to take a plus or minus sign ( both a and -a squared give the same result!)
