Step-by-step explanation:
Answer:
3.14 x 10^-7
Step-by-step explanation:
move the decimal behind the first significant figure and count the amount of spaces from there to the original decimal place
Answer:

Step-by-step explanation:
move the decimal so there is one non-zero digit to the left of the decimal point. the number of decimal places you move will be the exponent on the 10. if the decimal is being moved to the right, the exponent will be negative. if the decimal is being moved to the left, the exponent will be positive.
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:
units I THINK
Step-by-step explanation:
using the distance formula, -2 - 1 = -3
-3 x -3 = 9
-5 - 4 = -9 x -9 = 81
81 + 9 = 90
sqrt 90 simplified is
.
so im pretty sure that's the answer.
