The depreciation expense for each year to the new delivery truck purchased by Cookie Palace would be $4, 375.
How to find depreciation?When given the residual value, depreciation can be found using the straight - line method which has the formula:
= (Cost of delivery truck - residual value) / Number of years in estimated life
Solving for the depreciation expenses each year gives:
= (20, 000 - 2, 500) / 4
= 17, 500 / 4
= $4, 375
In conclusion, the depreciation to the delivery truck every year would be $4, 375.

What is a Triangle?Triangle ABC is the display style for a triangle with vertices A, B, and C.
In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces.
One of the internal angles of a right triangle (also known as a right-angled triangle) measures 90 degrees (a right angle). The hypotenuse, the triangle's longest side, is the side that faces the right angle. The triangle's other two sides are referred to as its legs, Right triangles follow the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs of a right triangle (a2 + b2 = c2). Special right triangles have extra characteristics that simplify computations involving them. The 3-4-5 right triangle is one of the two most well-known.

A firm manufactured 1000 Tv sets during its first year.the total firms production during the 10 year of operationis 29035 sets .
For each the level of output for 15th year using per year constant increase in production .
Answer:
6922 TV sets
Step-by-step explanation:
You want the production in the 15th year if production in the first year is 1000 and it increases yearly by a constant amount. The total production in the first 10 years is 29035.
Arithmetic seriesAn arithmetic series is one that has a constant difference from one term to the next. If a1 is the first term of the series, and d is the common difference between terms, the n-th term is ...
an = a1 +d(n -1)
And the sum of n terms is ...
Sn = (2a1 +d(n-1))(n/2)
ApplicationTo find the 15th term, we can make use of the given values to find the common difference, then use the formula for the n-th term.
S10 = (2(1000) +d(10 -1))(10/2) . . . . . sum formula with a1=1000
29035 = 10000 +45d . . . . . . . . . . . simplified
d = (29035 -10000)/45 = 423 . . . . the increase in production each year
Production in the 15th year is ...
a15 = 1000 +423(15 -1) = 1000 + 5922 = 6922
The output in the 15th year was 6922 TV sets.
7 The profit function, p(x), for a company is the
cost function, c(x), subtracted from the revenue
function, (x). The profit function for the
Acme Corporation is p(x) = -0.5x² + 250x - 300
and the revenue function is r(x) = -0.3x² + 150x.
The cost function for the Acme Corporation is
1) c(x) = 0.2x² - 100x + 300
2) c(x) = 0.2x² + 100x + 300
3) c(x) = -0.2x² + 100x - 300
4) c(x) = -0.8x² + 400x - 300
The cost function for the Acme Corporation is -0.2x² + 100x - 300. a cost function, transfers an event or the values of one or more variables onto a real number that signifies the event's "cost" in real terms.
How to find cost function ?A loss function, also known as a cost function, is a function used in mathematical optimization and decision theory that transfers an event or the values of one or more variables onto a real number that intuitively represents some "cost" connected to the occurrence. A loss function is the goal of an optimization problem.
The event in question is some function of the difference between the estimated and true values for a particular instance of data, and in statistics, parameter estimation is typically done using a loss function.
Given that the profit function is
p(x) = 0.5x^2 + 250x+300
also given that the revenue is given as
r(x) = 0.3x^2 + 150x
we know that profit= revenue - cost
hence cost = revenue-profit
cost = r(x) -p(x)
cost= 0.3x^2 + 150x-(0.5x^2 + 250x+300)
cost= 0.3x^2 + 150x-0.5x^2 - 250x-300
collect like terms
cost=0.3x^2-0.5^2+150x-250x-300
The cost function for the Acme Corporation = -0.2x^2-100x-300

8x + 16x - 12 = 24x- 12
Does the equation have one,
none, or infinite solutions?
Explain why.
Answer:
Infinite solutions
Step-by-step explanation:
The equation is,
→ 8x + 16x - 12 = 24x - 12
Let's solve for the value of x,
→ 8x + 16x - 12 = 24x - 12
→ 24x - 24x = -12 + 12
→ [ 0 = 0 ]
Hence, it has infinite solution. Because, all the real numbers are suitable.
Answer:
infinite number.
Step-by-step explanation:
Comment
There is only the same letter (x) on both sides of the equation. None of the xs are raised to any power. The power is 1 for all of them. That being so, there is only ONE solution.
x^2 + 5x + 6 would give 2 solutions because the x is raised to the second power.
x^3 + x^2 + 4x + 9 would give 3 solutions.
Solution
8x + 16x - 12 = 24x - 12 This equation is a little different. Both sides are exactly the same -- 24x - 12. That means that there is an infinite number of solutions.
For example let x = 10
The right side = 240 - 12 = 228
The left side = 8*10 + 16*10 - 12 = 228
You can't come up with a number that will make the left side unequal to the right side.
The revenue function is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x) is the unit price. If p(x)=26(4)−x5, find the revenue if 15 units are sold. Round to two decimal places.
If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.
How to calculate the amount of revenue at p(15)?From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):
R(x) = x × P(x)
Where:
x represents the number of units sold.p(x) represents the unit price.Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:
Revenue, R(x) = x × 26(4)^{-x/5}
Substituting the given parameters into the formula, we have;
Revenue, R(x) = 15 × 26(4)^{-15/5}
Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³
Revenue, R(x) = 15 × 26(0.015625) or 390/64
Revenue, R(x) = 6.09375 ≈ $6.09.

Main body:
Given that,
Which graph represents the function f(x) = 4⌈x⌉?
Now,
to represent the graph of Y = IxI-4 .
So,
Taking x = 0, we get
Y = IxI -4
Y = I0I -4
Y = -4
Taking x = 1, we get
Y = IxI - 4
Y = I1I -4
Y = -3
Taking x = 2, we get
Y = IxI - 4
Y = I2I - 4
Y = -2.
Taking x = -1, we get
Y = IxI - 4
Y = I-1I - 4

Margin did the successful candidate win is 5375 - 4300 = 1075.
Given:
In an election for a corporation seat, there were two candidates. A total of 9,791 votes were polled.
116 votes were declared invalid. The successful candidate got 5 votes for every 4 votes his opponent had.
Number of valid votes = 9791 - 116 = 9675.
Let the number of votes of successful candidate = 5x
Let the number of votes of opponent = 4x
5x + 4x = 9675
9x = 9675
divide by 9 on both sides
x = 9675/9
x = 1075
Hence the votes for successful candidate = 5*1075 = 5375.
votes for opponent = 4*1075 = 4300.

How to find x here if the perimeter, diagonal, and length is given?
Answer:
see explanation
Step-by-step explanation:
(a)
perimeter (P) is calculated as
P = 2(l + b) ← l is the length and b the breadth
given l = x and P = 20 , then
2(x + b) = 20 ( divide both sides by 2 )
x + b = 10 ( subtract x from both sides )
b = 10 - x
Using Pythagoras' identity in the right triangle
x² + (10 - x)² = 8²
x² + 100 - 20x + x² = 64 ( subtract 64 from both sides )
2x² - 20x + 36 = 0 ( divide through by 2 )
x² - 10x + 18 = 0 ← as required
(b)
solve using the method of completing the square
x² - 10x + 18 = 0 ( subtract 18 from both sides )
x² - 10x = - 18
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 18 + 25
(x - 5)² = 7 ( take square root of both sides )
x - 5 = ± [tex]\sqrt{7}[/tex] ( add 5 to both sides )
x = 5 ± [tex]\sqrt{7}[/tex]
Then
x = 5 - [tex]\sqrt{7}[/tex] ≈ 2.35 ( to 3 significant figures )
x = 5 + [tex]\sqrt{7}[/tex] ≈ 7.65 ( to 3 significant figures )
