Remark
When you take the limit of
the odd result you get is 1. Later on you will be able to use calculus to show this. For now just take limits of sin(x)/x and make sure you are feeding radians into your calculator.
Now the only question is what is this thing doing?
If a is a constant in
then the result = a.
So that's basically all you need to know to solve your problem.
Series
Each term in the series will be
a*(sin(ax)/x) = a * [sin(ax)/x] * 1 = a * a = a^2
The series will look like this.
1 + 4 + 9 + 16 + 25 + 36 + 49 + 64 + 81 + 100 There is a way of summing this using n notation, but you could just as easily just add the results.
<span>
The formula for this series (if you want a sum) is n*(n+1)*(2n+1) / 6
</span>n = 10
Sum = 10*(11)(21)/6
Sum = 385
Does adding it by hand bring up 385?
Answer:
431.3 ft
Step-by-step explanation:
Circumference=π(80ft)=251.3
90+90+251.3=431.3ft
p.s. I think we have the same teacher for Math 107 lol
Answer:
29 and 71
Step-by-step explanation:
29 + 71 = 100
So, 29 and 71 is the answer.
Answer: Debt- Equity ratio is 0.41
Step-by-step explanation: Debt- Equity ratio is calculated by subtracting one from the equity multiplier.
To solve this problem the du pont analysis is used which is Return on equity = Profit margin * Total Asset turnover * equity multiplier
0.1834 = 0.062 × 2.10 * Equity multiplier (EM)
0.1834 = 0.1302
EM = 1.41
Therefore debt-equity ratio = EM - 1
= 1.41 - 1 = 0.41
That would be (1, -3) because you basically divide the coordinates by the scale factor, in this case 2.
