Answer: 0.22hz
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
- <em>Period (T) = 4.5 Seconds
</em>
So, to calculate the frequency of the pendulum we have to apply the formula;
Frequency (f)= 1 / period
Replacing with the value given:
f = 1/ 4.5 sec = 0.22 hz
Feel free to ask for more if needed or if you did not understand something.
Answer:
The standard deviation is 5.29 kg.
Step-by-step explanation:
The standard deviation is the square root of the variance. Mathematically, we have that:
In this problem, we have that:
So
The standard deviation is 5.29 kg.
Answer:
x = 100°
y = 125°
z = 55°
Step-by-step explanation:
A straight line is 180°
A triangle is 180°
Solve in this order:
X: 180 - 80 = 100
Z: 180 - 80 - 45 = 55
Y: 180 - 55 = 125
<span>Answer:
We'll have to integrate the growth rate with respect to time, without forgetting the amount of area covered at the start.
A = 2010 + â« 8t1/2 dt (as t goes from 0 to 24)
A = 2010 + [(16/3) t3/2] (as t goes from 0 to 24)
A = 2010 + 627 = 2637 acres
We don't integrate the 2010 here because whatever effects of the passing of time have already taken place over that area. We just treat it as a constant and add it to the result of integration.</span>
