PLEASEE HELP!

Answer:

Two non zero vectors, a and b are parallel when they are scalar multiples of each other such that a = c·b where c is a scalar quantity.

Therefore, in order to find a vector that is parallel to the vector, b = (-2, -1), we multiply the vector, b by a scaler quantity

Step-by-step explanation:

Given that the vector b = (-2, -1) can be written as follows;

b = -2·i - j, we have;

\left | b \right | = √((-2)² + (-1)²) = √5

Therefore, we have;

The coordinates of the endpoint of the vector are (-2, 0) and (0, -1)

Therefore, the slope of the vector = (-1 - 0)/(0 - (-2)) = -1/2

The slope of parallel vectors are equal, which gives the slope of the parallel vector = -1/2 = (λ × (-1 - 0))/(λ ×(0 - (-2))

Therefore, a parallel vector is obtained from a vector by multiplying with a scaler product.

What is the quotient of 6 and -1/2
Grace [21]
Quotient means divide, meaning we'll divide 6 by -1/2.
6 \div - \frac{1}{2}
When dealing with fraction division, we flip the fraction in the second place and then change the problem to multiplication.
6 \cdot - \frac{2}{1}
Anything over 1 is just itself, so -2/1 becomes -2.
6 \cdot -2
Finally, we multiply 6 and -2.
6 \cdot -2 = -12
So the quotient of 6 and -1/2 is -12.

Plz explain me this question......
HACTEHA [7]
The question is totally irrelevent in context with the question. It's missing the "if she wants to only get different flavours".

For example, the answer could be:
1. Use her feet
2. Blind folded
3. Chained up behind her back

Ostrovityanka [42]

If he wants to sell buttons, say 40 buttons, he will get a profit of 1000 cents. And one dollar is equal to 100 cents so he only earns 10 dollars. However, the costs for the machine are 125 dollars. Therefore he has a loss of 115 dollars.
