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.
Try going for B because do 8 times 0.50 and 0.25 times 33 = to 12.25
Answer:
10-35-45 and 5-17.5-22.5
Step-by-step explanation:
Answer:
20.25 per cup because 81÷4= 20.25 then
1) read the label=81 per 4-cups
2) 20.25x4=82 calories
Step-by-step explanation:
hope this helps :D
