Answer:
Speed = 20 m/s
Step-by-step explanation:
The formula to find the speed of a wave is found by
Speed = Wavelength x Frequency where the frequency is in HZ and the wavelength is in meters
Speed = .80*25
Speed = 20 m/s
Answer:
<h2>1/4</h2>
Step-by-step explanation:
Area of a circle is given as πr² and its circumference is expressed as 2πr.
If the babylonians determined the area of a circle by taking it as equal to the square of the circle’s circumference then;
Area of circle = (circumference of a circle)²
πr² = (2πr)²
πr² = 4π²r²
Dividing both sides of the equation by πr² we have;

The value of π this yields is 1/4
Answer:

Step-by-step explanation:
try using a sphere calculator next time its a lot easier and saves time
Answer:
or 1.414
Step-by-step explanation:
1) Find the mean. 1+2+3+4+5 = 15. 15/5= 3
2) For each data point, find the square of its distance to the mean. (4, 1, 0, 1, 4)
3) Sum the values from Step 2. 10
4) Divide by the number of data points. 10/5= 2
5) Take the square root. 
I think it's (3) Calculate the nth term rule of the sequence
(I think
the answer to the equation is 8xy+36x+6y+9)
