Answer:
<h2>
The intensity in decibel is 320 decibel </h2>
Step-by-step explanation:
Given the intensity, or loudness, of a sound measured in decibels (dB), according to the equation where;
I is the intensity of a given sound and
is the threshold of hearing intensity
To get I(dB) when
We will substitute the value of I = into the equation above to have;
Since log10 = 1;
The intensity in decibel is 320 decibel
Answer:
The correct answer is C.
Step-by-step explanation:
The given equation is;
This implies that;
Let us write in Cartesian coordinates by substituting;
Square both sides;
This implies that;
This is an equation of a parabola that opens upwards with a y-intercept of .
The correct choice is C
Answer:
2.507* 10^-4
Step-by-step explanation:
0.0002507
We need to have one number to the left of the decimal
We move the decimal 4 places to the right
Since we moved the decimal to the right, the exponent on the power of 10 is negative
2.507* 10^-4
Answer:
-19/132
Step-by-step explanation:
To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get = =
The answer is one third or 1/3 multiply diagonal both ways and then multiply denominators
