Answer:
51
Step-by-step explanation:
when n=1
<h2><u><em>t 1=1 </em></u></h2>
<u><em>when n=2</em></u>
<u><em>t2=4</em></u>
<u><em>as first term is 1 and second term is 4 so the common difference is 3 ,for 6 term if you put this in formula for sum to the n term you will get 51 </em></u>
<u><em>t1 =1</em></u>
<u><em>d=3</em></u>
<u><em>n=6 </em></u>
<u><em>than S6=51 </em></u>
Answer:
0, 1, 4, 5, 6, and 9 can be the last digits of the squares of natural numbers.
Step-by-step explanation:
When looking at a list of the perfect squares, the last digits continuously follow this pattern: 1, 4, 9, 6, 5, 6, 9, 4, 1, 0. After this it repeats. This means that these are the only numbers that can be the last digits. When you take out the repeated numbers you get: 1, 4, 5, 6, 9, 0 which when written in order is:
0, 1, 4, 5, 6, and 9
Answer:
11
Step-by-step explanation:
58=2 x length + 2 x height.
58-(18 x 2)=58-36=22
22/2=11
Step-by-step explanation:
To solve this question I would use the sin rule.
The sin rule states that
Therefore if you substitute in your numbers you get:
If you rearrange that you get:
Therefore a = 17.3 Inches (to 3 sf)
This can also be done with basic trigonometry where you would get
Rearranging to
meaning the answer is 13.7 inches
