Raman buys two packages of chicken. One package weighs 1.5 pounds and the other weighs 3.4 pounds. The chicken cost 3.25 per pound. What is the total price? the answer is 8:00
Answer:
1/13
Step-by-step explanation:
there are 4 jacks in a deck of 52 cards
therefore probability of picking a jack:
4/52 = 1/13
We need to find dot products of 2 vectors:
u·v = x1*x2 + y1*y2
u·v = 2*(-6) + 3*4 = -12 + 12 = 0
Another way to write dot product u·v = |u|*|v|*cos α.
Because the do product = 0, we can write
|u|*|v|*cos α = 0.
That means cos α = 0, and thus α=90⁰, so vectors v and u are orthogonal.
1/3 opposite is -1/3 less than 12
