Answer:
Step-by-step explanation:
-A rectangle's area is given by:
Given A=
and 
, we substitute in the formula to solve for the width as follows:
Hence , the rectangle's width is 
The vector AB is found by subtracting the coordinates of point B from the coordinates of point A => (8, 3, 4) - (5, 7, - 2)
(8, 3, 4) - (5, 7, - 2) = (3, - 4, 6)
=>
a) a 3 x 1 column =
| 3 |
| -4 |
| 6 |
b) xi + yj + zk
=> 3i - 4j + 6k
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
The answer is 101.0769236761231
but just write 101 because i think the others are no need to write and
if you want to divide use your calculator
