Answer:
Step-by-step explanation:
To prove that 
is a multiple of 7.
Proof by induction:
Let n =1. Then we have 8-1 =7 is a multiple of 7
Thus the P(1) is true.
Let us assume that P(n) is true.
= 7l is true for some integer l
To check for P(n+1)
=LHS
=
Thus we find that this is also a multiple of 7.
If true for n, then true for n+1
Hence we find that since true for 1, we have it is true for all natural numbers.
Answer:
b(4) = -14
Step-by-step explanation:
b(n)=4-6(n-1)
let n=4
b(4) = 4 - 6(4-1)
b(4) = 4-6*3
b(4) = 4-18
b(4) = -14
Answer:
100,000
Step-by-step explanation:
The 9 is in the hundredth thousand place
I think the answer is A.
the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.
