Answer:
x is the number of years and y is the value at x years
We solve this problem by using the decibels formula which is expressed as:
dB = 10 x log (Isig/Iref)
where dB is decibels, Isig is the intensity of the signal and Iref is the intentsity of the softest sound the human ear can hear which has a value of 10^-12.
We solve as follows:
dB = 10 x log (<span>1.25 x 10–4 </span>/ 10^-12 ) = 80.97 decibels
Therefore, the correct answer is option A, 81 decibels.
Answer:
A = 532 ft^2 total
Step-by-step explanation:
There are 3 sets of 2 identical areas: 2 top/bottom, 2 sides, 2 ends.
Suppose the length is 14 ft, the width 7 ft and the height 8 ft.
A = 2 * (base area) + 2 * (end area) + 2 (side area)
= 2 * (98 ft^2) + 2 * (56 ft^2) + 2 (112 ft^2)
= 196 ft^2 + 112 ft^2 + 224 ft^2
A = 532 ft^2 total
Answer:
Step-by-step explanation:
(0.4)^3= (0.4)(0.4)(0.4)= (0.16)(0.4)= 0.064
the answer is D
Answer: F
Step-by-step explanation:
becuse we do not have the thing so the answer would be F
