Answer:
Step-by-step explanation:
Given
--- Intensity
Required
Determine the decibel level (D)
This is calculated as:
Where:
The threshold intensity
So, we have:
This gives:
Apply law of indices
Apply law of logarithm
So, we have:
So:
<em>Hence, the decibel level is 50</em>
There can only be integer number of passengers. We cannot have 1.372 passengers in a car, so that would be discrete random variable.
If you would like to solve for f(g(x)) when x = 1, you can do this using the following steps:
<span>f(x) = x^2 - 3x + 6
g(x) = x - 3/2
f(g(x)) = f(</span>x - 3/2) = (x - 3/2)^2 - 3 * (x - 3/2) + 6
x = 1
f(g(1)) = f(1 - 3/2) = f(-1/2) = (-1/2)^2 - 3 * (-1/2) + 6 = 1/4 + 3/2 + 6 = 1/4 + 6/4 + 24/4 = 31/4 = 7 3/4
The correct result would be 7 3/4. add me as a friend
Answer:
Using the quadratic formula to solve 5x = 6x^2 – 3, what are the values of x?
5x = 6x^2 – 3
Subtract 5x from both sides:
0 = 6x^2 – 5x – 3
a = 6, b = -5, c = -3
x = (-b ± √(b^2 - 4ac))/(2a)
x = (-(-5) ± √((-5)^2 - 4(6)(-3)))/(2(6))
x = (5 ± √(25 + 72))/12
x = (5 ± √(97))/12
Step-by-step explanation:
Answer: 119.57 cu. ft.
Step-by-step explanation:
Volume of a hemisphere = (2/3)πr^3
= (2/3) * 22/7 * 3.85^3
