Your answer would be, A. <span>3√ 2. Hope I helped you :)</span>
In this problem, you are asked to write a number in
scientific notation. In figures, 78 million would look like this:
78,000,000
To write this to scientific notation, you have to move the
decimal point to the left until you will get a number between 1 and 10.
Here, you will have to move the decimal point 7 times to get
7.8
The exponent of the scientific notation is the number of
times you moved your decimal point. Since the movement of decimal point is
going to the left, you will have a positive exponent.
The scientific notation would look like this:
7.8 x 10^7
Answer:
x = 7
Step-by-step explanation:
divide the five on both sides, and you get x = 7
best of luck!
Hello.
The further away from the speakers you are t<span>he less intense the sound will be.
</span>
<span> If sound intensity varies inversely with the square of the distance, you can represent this as: </span>
<span>I = 1/d^2 </span>
<span>If you double the distance: </span>
<span>I = 1/(2d)^2 </span>
<span>I = 1/4d^2 </span>
<span>I = 1/4d^2 </span>
<span>so by doubling the distance, you have 1/4th the intensity.
</span>
Have a nice day
