Answer:
Multiply vector c by the scalar -1/2.
Step-by-step explanation:
Look at vector c.
It has an x component of 4 and a y component of 4.
You can write vector c as a sum of its components using unit vectors in the x direction (i) and in the y direction (j).
c = 4i + 4j
Now look at vector d, and write it also as a sum of its x and y components.
d = -2i - 2j
Now ask yourself, what operation do I do to 4 to end up with -2?
One answer is to multiply 4 by -1/2.
d = (-1/2)c = (-1/2)(4i) + (-1/2)(4j) = -2i - 2j
That worked. By multiplying vector c by the scalar -1/2, you end up with vector d.
Answer:
8
Step-by-step explanation:
Total pints of paint = 20
For landscape :
2/5 * 20 = 8 pints
For clover :
3/10 * 20 = 6 pints
Total used = (8 + 6) = 14
Pints left = 20 - 14 = 6 pints
14 required for next painting
14 - 6 = 8 pints
8 more pints needed
(45+20)/(42+45+20+32)
65/139
