Answer:
Step-by-step explanation:
Given
Geometric Sequence (GP)
Required
Determine T₁₂
The nth term of a GP is calculated as thus;
In this case;
; and 
Substitute these values in the above formula
Open the bracket
<em>Hence, the 12th term of the sequence is </em>
So, 672 miles divided by 56 miles per hour = 12 hours
Part÷Whole=Percent÷100
Part=X
Whole=55
Percent=222
X÷55=222÷100. Set this up in fraction form, cross-multiply and you will get 100x=222×55
222×55=12,210
100x=12,210: Divide by 100.
X=Part=122.1
Answer: B-A
Step-by-step explanation:
We know that it is -A - (-B)
The negative sign on the A stays as it is, eliminating choices A-B and A+B.
For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.
Therefore, the answer is -A+B, or B-A. Hope it helps!
