Depreciation is the reduction in the value of an asset over time, due in particular to wear and tear.
What is depreciation?
Your information is incomplete. Therefore, an overview will be given. depreciation refers to an accounting method used to allocate the cost of a tangible or physical asset over its useful life.
To calculate depreciation, subtract the asset's salvage value from its cost. The result is the depreciable basis or the amount that can be depreciated. Divide this amount by the number of years in the asset's useful lifespan.

Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar(s). a professor is examining a new strain of bacteria. the amount of bacteria can be modeled by function s(n) = 20 · bn, where n is the number of hours and b is an unknown positive base. based on the model, there were initially bacteria. if b = 1.85, the hourly percent growth rate of the bacteria would be %.
The equation s(n) = 20.bn is an exponential equation, and the hourly percent growth rate of the bacteria would be 85%.
How to determine the hourly percent growth rate?The value of b is given as:
b = 1.85%
Let the hourly percent growth rate of the bacteria be r.
So, we have:
b = 1 + r
Substitute b = 1.85%
1.85 = 1 + r
Subtract 1 from both sides
r = 0.85
Express as percentage
r = 85%
Hence, the hourly percent growth rate of the bacteria would be 85%.

Step-by-step explanation:
Formula:
A = Lw
Note:
A rectangle has 3 set of different side.
Solve:
A = Lw
A = 5 × 9
A = 45 × 2
A = 90
A = Lw
A = 5 × 3
A = 15× 2
A = 30
A = Lw
A = 3 × 9

What substitution should be used to rewrite 6(x 5)2 5(x 5) – 4 = 0 as a quadratic equation? u = (x 5) u = (x – 5) u = (x 5)2 u = (x – 5)2
The substitution that should be used to rewrite 6(x+5)^2 + 5(x+5) - 4 = 0 is u = x + 5
Quadratic equationsThese are equations that has a leading degree of 2. Given the expression
6(x+5)^2 + 5(x+5) - 4 = 0
In order to simplify this equation, we will replace the reoccuring term by a variable.
From the equation we can see that (x+5) is occuring the most. Let u = x + 5 so that:
6u^2 - 5u - 4 = 0
Hence the substitution that should be used to rewrite 6(x+5)^2 + 5(x+5) - 4 = 0 is u = x + 5

The mathematics faculty at a college consists of 7professors, 9 associate professors, 9 assistant professors, and 9 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor.
=============================================================
Explanation:
There are 7 professors and 9 instructors (first and last items mentioned).
So there are 7+9 = 16 people who are either a professor or an instructor, but not both. I'm assuming the job titles do not overlap, ie no one person has more than one title. The events "professor" and "instructor" are mutually exclusive. I'm leaving out the associate professors and assisant professors.
In total, there are 7+9+9+9 = 34 faculty members.
--------------
We found there are 16 faculty members who are either a professor or an instructor, out of 34 total members.
This must mean the probability we want is 16/34 = 8/17
Side note: 8/17 = 0.4706 = 47.06% approximately
Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m. How long did Michelle work on the puzzle?
Answer:
44 minutes
Step-by-step explanation:
Given:
Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m.
To Find:
How long did Michelle work on the puzzle?
Solve:
Began Time ⇒ 7:50 p.m
End Time ⇒ 8: 34 p.m
Since they are both p.m we could just subtract 8:34 by 7:50.
But first we know that:
8: 34 the 34 can't be subtracted by 7:50 the 50.
Thus we know that:
1 Hour = 60 minutes
Hence,
changing 8:34 p.m from 1 hour to 60 minutes. Which given us 7:94.
Then,
7:94 - 7:50
= 44
Hence, Michelle work on the puzzle for 44 minutes.

An observer 160 meters away sees a rocket launch into the
air. The rocket reaches its maximum height when the ob-
server is looking at an angle of 75° relative to the ground.
What is the approximate maximum height of the rocket's
path, in meters?
Not Answer:
8
Step-by-step Non-explanation:
The first term ( -4.9(t-4)^2 ) can never be positive, so the maximum height of 80 meters is achieved when t = 4. So the rocket will reach its maximum height after 4 seconds.
The approximate maximum height of the rocket's path is 597.13 meters.
How to elaborate the problem ?
Observer sees the rocket 160 meter away from the place where rocket launched.
75° is the angle between observer and rocket, when the rocket reaches its maximum height.
Here, if we assume a triangle whose base = distance between rocket launch point and the observer.
Height = Maximum height of the rocket
How to calculate the maximum height of the rocket ?Here, Base = 160 meter & let, maximum height = h
tan 75° = [tex]\frac{height}{base}[/tex]
⇒ tan 75° = [tex]\frac{h}{160}[/tex]
⇒ h = 160 tan 75°
⇒ h = 597.13 (approx)
The maximum height of the rocket is 597.13 meters (approx).

2 two angles are supplementary. The
measure of one angle is 9 times the
measure of the other angle. What is the measure of the smaller angle
Answer:
18 degrees heres youre answer!
Step-by-step explanation:
If Angle 1 is x, and Angle 2 is 9x (because one angle is 9 times as large as the other), then x + 9x = 180. Add like terms: 10x = 180. solve for x by dividing both sides by 10. Therefore, x = 18 degrees = smaller angle.

I don’t understand the equation
Step-by-step explanation:
it does not matter, if you understand the equation itself. look at the graph ! what is the curve doing ?
I don't know the options of the pull-down menus, so I will give you my best guesses based on the facts :
the domain of a function is the set or interval of all valid x (or input) values.
the range of a function is the set of interval of all valid y (or functional result) values.
so, clearly, x is in the interval (-infinity, +infinity). which is therefore the domain.
please conduct the round brackets. they indicate that the specified interval limits are not included (as infinity is not a value, only a concept, and can never be reached).
and y is in the interval of (0, +infinity). which is therefore the range.
we have to use the round brackets also for 0, as the function will never deliver the value 0, but its tendency or limit goes there (but again, only in infinity, which will never be reached).
the function continuously decreases when x increases.
again, I am not sure what the options are here, and what your teacher wants to "hear".

but we have restrictions. we don't want the girls not just anywhere in the line, we want them to be at the end points of the line.
and none of the boys should ever be at one of the ends.

under these constrictions they have actually only 12 different ways to line up.
