Answer:
The increase in the value of the truck, which is 88%
Step-by-step explanation:
Depreciation can be defined as the reduction of cost of a fixed asset systematically until the value of the asset becomes zero.
Rate of return can be defined as the percentage of interest or dividends earned on money that is invested.
In Financial accounting, a return refers to the amount of profit generated by an investor on an investment over a specific period of time.
Basically, the rate of return which is typically expressed as a percentage of the initial costs of an investment can either be a gain or a loss on an investment. Therefore, a positive rate of return on an investment over a specific period of time, simply means that an investor is making a profit (gains) while a negative rate of return on an investment over a specific period of time, indicates that the investor is running at a loss.
Given the following function;
f(x) = 29,000(0.88)x
Where;
x is the number of years.
We can deduce from the function, that the rate at which the truck is appreciating is 88% (0.88).
Assuming x = 3
f(3) = 29,000(0.88)*3
f(3) = $76,560
Answer:
The decrease in the value of the truck, which is 12%
Step-by-step explanation:
If the decrease in the value of the truck was 88%, then the percentage would be 0.12. So therefore, since 1.00 - 0.12 is 0.88, the decrease in the value of the truck would be 12%.

5. Twenty volunteers with high cholesterol were selected for a trial to determine
whether a new diet reduces cholesterol. The volunteers were given a low-carb,
low-calorie diet. After 8 weeks of the diet, the average cholesterol of the
volunteers dropped a significant amount. This study is an example of
(A) A controlled experiment.
(B) An uncontrolled experiment.
(C) A double blind experiment.
Ablocked design experiment.
Answer:
(B) An uncontrolled experiment.
Step-by-step explanation:
In the case of an uncontrolled experiment here all participants are provided the similar treatment and there should be no comparison oppose to any group i.e. controlled
Since in the given situation, there are similar diets are provided to 20 volunteers and it can be that the cholesterol level is decreased after particular time period,
Hence, it is an uncontrolled experiment.
Thus, option B is correct.
The points plotted below are on the graph of a polynomial. How many roots
of the polynomial lie between x = -4 and x = 3?
URGENT
Given:
The graph of a polynomial.
To find:
The number of roots of the polynomial lie between x = -4 and x = 3.
Solution:
From the given graph it is clear that the graph is a downward U-shaped curve. It means the given graph represents a quadratic polynomial.
The graph of the polynomial is below the x-axis immediate before x=-2 and above the x-axis immediate after x=-2. It means the graph intersect the x-axis at x=-2.
The graph of the polynomial is above the x-axis immediate before x=2 and below the x-axis immediate after x=2. It means the graph intersect the x-axis at x=2.
Since the graph of the polynomial divides the x-axis two times between x = -4 and x = 3, therefore the two roots of the polynomial lie between x = -4 and x = 3.

Perpendicular to x+y=6 and passing through (0,1)
Answer:
y = x + 1
Step-by-step explanation:
x + y = 6
y = -x + 6
Perpendicular slope to -1 is 1
(0,1)
y - y1 = m(x - x1)
y - 1 = 1(x - 0)
y - 1 = x
y = x + 1
Standard form:
y = x + 1
-x + y = 1
Steps for solving 5(2x - 8) = 20 are shown. 5(2x-8)= 20 10x - 40 = 20 10x - 40+ 40 = 20 + 40 10x = 60 10x 60 10 10 x = 6 Original Equation Which of these is not part of the solution process?
Answer:
(d) Using the commutative property
Step-by-step explanation:
Given
The above steps
Required
Which is not part of the process
We have:
[tex]5(2x-8)= 20[/tex]
[tex]10x - 40 = 20[/tex]
[tex]10x - 40+ 40 = 20 + 40[/tex]
[tex]10x = 60[/tex]
[tex]\frac{10x}{10} = \frac{60}{10}[/tex]
[tex]x = 6[/tex]
Comparing the above steps with the given list of options, we can see that the commutative property is not applied at all.
Other properties are:
[tex]5(2x-8)= 20[/tex] ---- Distributive
[tex]10x - 40+ 40 = 20 + 40[/tex] ---- Like terms
[tex]\frac{10x}{10} = \frac{60}{10}[/tex] --- Isolating the variable

the mean of "n" numbers is "x" . if one more is added the mean is "y" . write an algebraic expression for the value of the number added?
Answer:
yn +y -xn
Step-by-step explanation:
Mean= sum of numbers ÷number of numbers
x= sum of n numbers ÷n
Multiply both sides by n:
xn= sum of n numbers
sum of n numbers= xn -----(1)
Let the number added be a.
After a has been added,
y= (sum of n numbers +a) ÷(n+1)
Multiply both sides by (n +1):
y(n +1)= sum of n numbers +a
sum of n numbers= y(n +1) -a -----(2)
Substitute (1) into (2):
xn= y(n +1) -a
Expand:
xn= yn +y -a
a= yn +y -xn
Let's check!
Let the numbers be 1, 2, 3 and 4.
mean, x= 10 ÷4= 2.5
n= 4
Let the new number added, a, be 7.
a= 7
mean, y= 17 ÷5= 3.4
a= yn +y -xn
a= 3.4(4) +3.4 -2.5(4)
a= 7
Thus, the expression is true.
Mr. Miller is putting a border around the edges of a rectangular ceiling. The perimiter of the ceiling is 18 meters. What are the two dimensions?
Answer:
Length & Breadth could be : 4 meters , 5 meters
Step-by-step explanation:
Border, ie perimeter measurement of Rectangle = 2 ( Length + Breadth )
So, 2 (Length + Breadth) = 18
Length + Breadth = 18 / 2
Length + Breadth = 9
So, sum of length & breadth must be = 9.
(L, B) = (2,5) ; (2,8) ; (2,9) and (3,5) ; (3,8) ; (3,9) don't satisfy this condition. (4,5) ; (4,8) also don't.
(L, B) = (4,5) satisfy it. As sum 4 + 5 = 9.

When theres a triangle with a right angle you need to make in a rectangle and divide it by 2
Answer:
In order to find the area of a triangle, you need to use the formula [tex]\frac{1}{2} bh[/tex]. Substitute the known values into the formula and solve the equation.
Step-by-step explanation:
The formula to calculate the area of a triangle is [tex]\frac{1}{2} bh[/tex], where [tex]b[/tex] represents the length of the triangle's base, and [tex]h[/tex] represents the length of the triangle's height. Since [tex]b[/tex] and [tex]h[/tex] are variables that have different values in regards to different triangles, that means you should substitute the known/given values of each variable into the formula and solve the equation.

Answer:
Step-by-step explanation:
The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.
What is the section of the line?Let A (x₁, y₁) and B (x₂, y₂) be a line segment. Then the point P (x, y) divides the line segment in the ratio of m:n. Then we have
x = (mx₂ + nx₁) / (m + n)
y = (my₂ + ny₁) / (m + n)
The two endpoints are (-6, -2) and (8, -9). And m: n = 2: 5. Then the value of the x-coordinate is calculated as,
x = (2 · 8 + 5 · -6) / (2 + 5)
x = (16 - 30) / (7)
x = - 14 / 7
x = - 2
The x-coordinate of the point that divides the line segment will be -2. Then the correct option is B.

what is the mean,median,mode ,and range of 24,12,10,15,10,22,12
Answer:
24, 12, 10, 15, 10, 22, 12
mean: 7
median: 12
mode: 12
Range: 14
Step-by-step explanation:
Answer: Mean=15, Median=12, Mode=10 and 12, Range=14
Step-by-step explanation:
Data:
Numbers: 10, 10, 12, 12, 15, 22, 24
Mean: x, Median: x, Mode: x, Range: x
Step One, Find the Mean by adding all of the numbers and dividing them by the number of numbers
10+10+12+12+15+22+24=105/7=15
Mean=15
Reason: By adding all of the numbers together and dividing them by the number of numbers, you can find the mean because that is the method on finding the mean.
Step Two, Find the Median(middle) by finding the number in the middle
10, 10, 12, 12, 15, 22, 24
Median=12
Reason: Since the median is the number in the middle, 12 would be the median since it is the number in the middle of the array of numbers.
Step Three, Find the mode by finding the number that show up the most
10, 10, 12, 12, 15, 22, 24
Mode=10 and 12
Reason: Since mode is finding the number that shows up the most, 10 and 12 would be the answer for that reason and that they show up the same number of times in the array of numbers.
Step Four, Find the range by subtracting the biggest number by the smallest
24-10=14
Reason: Since to find the range you have to subtract the biggest number(24) by the smallest(10) the answer has to be 14 because that us the answer to 24-10.

A cuboid has 4 rectangular faces and 2 square faces. Each rectangular face measures 8 cm by 6 cm. Find the two possible values for the surface area of the cuboid.
pls give me answer with steps
Answer:
320 cm² or 264 cm²
Step-by-step explanation:
first, the rectangular face area is 4 faces at 8 x 6 = 192 cm²
the 2 square faces will be either 8 x 8 or 6 x 6.
If 8 x 8, then the SA will be 192 + (2 x 8 x 8 ) = 320 cm²
If 6 x 6, then the SA will be 192 + (2 x 6 x 6 ) = 264 cm²
