Answer:
a) 5
Step-by-step explanation:
Graphically, b - a can be represented by placing a vector of the same magnitude of a but opposite orientation at the end of vector b. Let's call this vector -a. |b-a| will be the vector that share origin with b and end with -a. The minimum value that the magnitude of |b-a| can have will occur when -a have the same direction of b but opposite orientation, and the maximum value when -a have the same direction and orientation. Mathematically, this would be:
|b-a|min = 12 - 5 = 7
|b-a|max = 12 - (-5) = 17
Notice that 5 is the only option that is not in this range, so the answer is a.
Answer:$2800
Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.
Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.
Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.
Since they sell for 8 days we just multiply 8*$350 to get $2800.

Answer:
189
Step-by-step explanation:
let the number be n , then number multiplied by itself is n² and
n² = 567 × 63 = 35721 ( take square root of both sides )
n =
= 189
