The first mistake was made in step 1 because they took out the x’s it should be 10x-25+2x+8=43
Answer:
step 3
Step-by-step explanation:
take away 2 add 4 then multiple 9000 then divide 1 then you got your answer 20/56.
Answer:
B
Step-by-step explanation:
Well, in order to answer this problem we need to use the <span>the Pythagorean Theorem and the it will be like this:
cos = x / hypotenuse
cos= 12/13
I think with this you can figure the rest out. Hope this helps</span>
Let
In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:
So, the base case is ok. Now, we need to assume 
and prove 
.
states that
Since we're assuming , we can substitute the sum of the first n terms with their expression:
Which terminates the proof, since we showed that
as required
