We have the given I = 10^-1 and I₀ = 10^-12.
Simply plugging in the values to the equation, we have:
L = 10log(10^-1/10^-12)
L = 110 Db
The answer is D.
(I used a scientific calculator in solving for L).
Answer:
<h2>DA is equal to <u>
25</u> or BA</h2>
Step-by-step explanation:
ABC
ADC
- Since we know that line CA is equal to line CA because of <em>reflexive property</em>
- Angle BAC and DAC are equal because of <em>definition of an angle bisector</em>
- Angle ABC and ADC are equal because of <em>definition of an angle bisector</em>
- This will give us <em>ASA</em>, proving to us that all sides and angles are congruent <u>(this was already given to us)</u>
- So, if BA is 25, and we know that BA is congruent to DA, this tells us that DA is 25
a) We have to calculate the height of the pad.
We know that the volume will be 4704 cubic feet.
We also know that the base of the pad is a square of side length 56 feet.
As the volume is the area of the base times the height, we can find the height by dividing the volume by the base area:

The height is 1.5 feet.
b) Now, we have a circular pad of which we know the height (1.5 feet) and the volume (4705 ft³). The area of the base will have to be the same as the are of the square: 3136 ft².
The area of this circular pad can be expressed as πD²/4, so we can calculate the diameter D as:

The diameter is approximately 63.21 feet.
Answer:
a) The pad will be 1.5 feet thick
b) The diameter will be 63.21 feet.
