Answer:
Emma is right because Jon put ¨2.5¨ notebooks when there are really $5
Step-by-step explanation:
The formula of a distance between two points:
We have the points (-1, 8) and (5, -2). Substitute:
Proving a relation for all natural numbers involves proving it for n = 1 and showing that it holds for n + 1 if it is assumed that it is true for any n.
The relation 2+4+6+...+2n = n^2+n has to be proved.
If n = 1, the right hand side is equal to 2*1 = 2 and the left hand side is equal to 1^1 + 1 = 1 + 1 = 2
Assume that the relation holds for any value of n.
2 + 4 + 6 + ... + 2n + 2(n+1) = n^2 + n + 2(n + 1)
= n^2 + n + 2n + 2
= n^2 + 2n + 1 + n + 1
= (n + 1)^2 + (n + 1)
This shows that the given relation is true for n = 1 and if it is assumed to be true for n it is also true for n + 1.
<span>By mathematical induction the relation is true for any value of n.</span>
Answer:
The rate of discount of a lawnmower is 37,5%
Step-by-step explanation:
Sale price formula is
S = p - rp
where S = sale price,
r = discount percentage rate
p = the original price.
Isolating r
r= (p-S)/p
r= ($168- $105)/$168
r=0.375
r= 37,5%
