The sound level, B, in decibels (dB), of a sound with an intensity of i is calculated in relation to the threshold of human hearing, i0, by this equation. B=10log(I/i0)

The threshold of human hearing is 10^-12 watts/meter^2.

The sound level of a jet plane is approximately 140 dB. The intensity of the sound of a jet plane is approximately ___ watts/meter^2.

A. 100
B. 1,000
C. 10,000
D. 10

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

answer: my brother can figure it out, imma go get him so i can answer : ) edit: my brother is sleeping, sorry man

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
