We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd
Answer: 32
Step-by-step explanation:
The answer would be 7+x*x the variables stand for the 2 unknown numbers and the product is the * symbol. Increased stands as the plus symbol. Hope this helps!
Answer:
∠RUP is 135°
Step-by-step explanation:
First find the angle of QUR
QUS is 90 so you just subtract 45 from 90 and you get 45
QUP is also 90. Add 45 to it this time: 135
Answer:
i think its $2
Step-by-step explanation:
because 1,2 could mean 1 bag = $2,
2,4 could mean 2 bags = $4, and so on.
