I = 7.6*10^(-4) is the given intensity of the sound
Io = 10^(-12), which is a constant usually shown in a table or in your book

Plug in those values to get
B = 10*log(I/Io)
B = 10*log((7.6*10^(-4))/(10^(-12)))
B = 88.808135922808
B = 88.81

Answer: Approximately 88.81 decibels

Solve the following equation.<br> x^2 + 6x − 40 = 0
jonny [76]

Answer:

x = 4 and -10

Step-by-step explanation:

Given the equation

x²+6x-40= 0

The common factors to use for the factorisation are +10 and -4

x²+(10x-4x)-40=0

(x²+10x)-(4x-40) = 0

x(x+10)-4(x+10) = 0

(x-4)(x+10) = 0

x-4 =0 and x+10 = 0

x = 4 and x = -10
