Antonia saves 64 dollars on the sixth day. You can figure this out by raising the number 2 to the 6th power.
I took the same test and I put the answer D. 1487 and I got it wrong. The correct answer was
A.3
Answer: yes, it is
Step-by-step explanation:
A number is divisible by 6 if it is divisible by 2 and 3 simultaniously.
n = k(k+1)(k-1)
If k-1 is a multiple of 3, n is divisible by 3, so one of the requirements is ok.
Now, if k-1 is a multiple of 3, it can be even or odd.
if k-1 is even, then it is divisible by 2 and as it is divisible by 3 as well, n is divisible by 6
if k-1 is odd, then k and k+1 is even, hence, divisible by 2.
As n = k(k+1)(k-1), n is also divisible by 6.
Relation - if we have two sets defined under certain condition which relates them then it is called relation.
Function - any relation is said to be function if every element of set A is uniquely related to set B. where we assumed any two arbitrary sets.
Answer:
Step-by-step explanation:
Use the formula of distance between the two points 
and 
,
Distance = 
1. Distance between A(3, 4) and B(8, 12),
AB = 
AB = 
= 
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = 
= 
= 
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = 
= 
= 
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM = 
= 
= 
= 10.77
