It will take 13 weeks to save the money to buy the equipment because if you subtract 20 you get 55.25 then divide by 4.25 you get 13 <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
Answer:
22
Step-by-step explanation:
square root of a number multiple by the himself give you the value
so square root of 22 x 22 = 22
(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.
Answer:
supplement: 137
complement: 47
Step-by-step explanation:
Supplement is two angles that equal 180, so just subtract 43 from 180.
complement is two angles that equal 90, so 90-43=47
