Answer: It
should be about 1.5 years
Step-by-step explanation:
Answer: g(x)=(9x+1)
Step by step explanation:
Step-by-step explanation:
49 = -16t^2 + 56t
-16t^2 + 56t -49 = 0
(-4t +7) (4t -7) = 0
-4t+7 =0
t = 7/4
<span>55 decibels.
Decibels is a logarithmic scale for power and is defined as 10 log(p1/p2). However, you need to be very precise in your language if you're speaking of decibels. For instance, a doubling of POWER means an increase of 3 decibels. a doubling of VOLTAGE means an increase of 6 decibels. And because of the ear's non-linear response to sound levels, a perceived doubling of LOUDNESS is an increase of 10 decibels. So the question mentioned loudness, I'll use the increase of 10 db per doubling of volume. 8 times is 3 doubling (2*2*2 = 8). So the increase in decibels is 3 * 10 = 30 decibels. So the decibel rating of a sound that sounds 8 times louder than a sound at 25 decibels is 25 + 30 = 55 decibels.</span>
