ANSWER
A) v1 is not perpendicular to v2
EXPLANATION
Two non-zero vectors are orthogonal or perpendicular if their dot product is zero.
In other words,if two non-zero vectors are not orthogonal or perpendicular then their dot product is not equal to zero.
From the question v1 and v2 are non-zero vectors and their dot product is not equal to zero.
This tells us that, the two vectors are not perpendicular.
The correct choice is A.
Answer:
The answer is -94 but where is b
Step-by-step explanation:
2(4)-6(17)=-94

8c + 4t = 45
3c + 2t = 20
Modify for elimination: ( multiply 2</span>nd<span> eq by -2)

Subtract and solve for "c":
2c = 5
c = $2.50 (cost of one chair)
Solve for "t":
3c + 2t = 20
3(2.50) + 2t = 20
7.50 + 2t =20</span></span>
2t=12.50
<span><span>T= 12.50/2 =6.25
</span>
t = $ 6.25 (cost of one table)</span>
Table = 6.25 each
Chair = 2.50 each
Check:
3(2.50) + 2(6.25) =
7.50 +12.50 = 20
8(2.50) + 4(6.25) =
20.00 + 25.00 = 45.00
Answer:
Step-by-step explanation:
The equation thus:
21/(12+1.50)
Answer:
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
