Answer: C
since the line isn't straight, the slope/function is decreasing but not at a constant rate
<em><u>The common difference d is </u></em>
<em><u>The first term is</u></em>
<em>so , the first term is -13 </em>
Answer:
B) 5 x 4 x 3 x 2 x 1
Step-by-step explanation:
When you see a ! directly next to a number (such as 5!), it means that you are multiplying starting from that number, and stepping down each time:
5! = 5 * 4 * 3 * 2 * 1
For example, take factoral 10: 10!
10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3,628,800
In this case, you are multiplying 5!.
5! = 5 * 4 * 3 * 2 * 1 = (20) * (6) * 1 = 120
5! = 120
In this sum we will calculate using the simple interest.
Simple interest is calculated from the formula :
I = PRT
where I is the interest, P is the principal, R is interest rate per year and t is time in years.
I = 2000 × 3 % x 2
We have to turn 3% to its decimal fraction which is 0.03, so:
I = 2000 × 0.03 × 2
I = 60 × 2
I = 120
Therefore the interest earned in two years will amount to 120 $
1 is L
2 is N
3 is M
Look back at your notes if you have any.
