The equation the function after the transformation is g(x) = x/10
How to determine the transformation of the function?The equation of the function is given as
y = x
Express as a function
f(x) = x
The sequence of transformations is given as follows:
Vertically stretched by a factor of 1/10
When the above transformations are combined, we have:
Vertically stretched by a factor of 4: g(x) = 1/10f(x)
So, we have
g(x) = 1/10f(x)
Substitute x for f(x)
So, we have
g(x) = 1/10 * x
Evaluate
g(x) = x/10
Hence, the function g(x) is g(x) = x/10

What is an histogram?An histogram is a graph that shows the number of times each element x was observed on the data-set.
Hence, the meaning of a point (x,y) on the histogram is given as follows:
Observation x was observed y times on the data-set.
The skewness of a distribution can be explained as follows:
Left-skewed: The higher values are the ones that are observed the most in the data-set.Symmetric: The middle values are the ones that are observed the most in the data-set.Right-skewed: The lower values are the ones that are observed the most in the data-set.Hence in this problem, for the left-skewed histogram, we want an "increasing" histogram, hence option A is correct.

The mean, median and mode of the numbers below are the same,
what is the value of a?
6, 2, a, 7, 4, 9,6
Answer:
8
Step-by-step explanation:
Put the numbers in order from lowest to highest. Add all the numbers together. We will ignore a for this step. You should get 34 when adding it all together. Then if you were to add 8 to that 34 you'd get 42. Divide 42 by the amount of numbers you have which is 7. Your answer is 6. Now to make sure 8 is our value. We want to make sure the median is also 6. to find the median you need to have the numbers in order for lowest to highest and find the number in the middle. Don't forget to add your new number 8 into that order. You should get 6 as the median. Therefore our answer is 8

The population growth rate (r) for 2009 in the tiny country of fremont is found as 1.4.
Describe the term population growth rate (r)?The population growth rate (r) shows how fast a population ages over time. A population is growing if the growth rate is positive. A negative growth rate signals a declining trend. A birth rate (b) and mortality rate are the two primary elements that influence population increase (d). People leaving the population to move to another territory or immigrating from a different region may also have a consequence on population increase (emigration, e).All these elements are taken into account when formulating the population growth formula.
r = [(b + i) - (d + e)]/1000
r = population growth rateb = birth rate; 2,000i = immigration rate; 100d = death rate; 500e = emigration rate; 200Put the values in the formula.
r = [(2,000 + 100) - (500 + 200)]/1000
r = 2100 - 700/ 1000

Muscle Density:Muscle mass (quantity) is highly correlated with survival in hospitalized patients with advanced cancer, whereas muscle density (quality) is associated with patients’ symptoms, health care use, and survival, according to a group of researchers
Correlation:In statistics, correlation or dependence is any statistical relationship, whether causal or not, between two random variables or bivariate data. Although in the broadest sense, "correlation" may indicate any type of association, in statistics it usually refers to the degree to which a pair of variables are linearly related. Familiar examples of dependent phenomena include the correlation between the height of parents and their offspring, and the correlation between the price of a good and the quantity the consumers are willing to purchase, as it is depicted in the so-called demand curve.
Your body shape changes naturally as you age. You cannot avoid some of these changes, but your lifestyle choices may slow or speed the process.
The human body is made up of fat, lean tissue (muscles and organs), bones, and water. After age 30, people tend to lose lean tissue. Your muscles, liver, kidney, and other organs may lose some of their cells. This process of muscle loss is called atrophy. Bones may lose some of their minerals and become less dense (a condition called osteopenia in the early stages and osteoporosis in the later stages). Tissue loss reduces the amount of water in your
The amount of body fat goes up steadily after age 30. Older people may have almost one third more fat compared to when they were younger. Fat tissue builds up toward the center of the body, including around the internal organs. However, the layer of fat under the skin gets smaller.

People typically lose almost one-half inch (about 1 centimeter) every 10 years after age 40. Height loss is even more rapid after age 70. You may lose a total of 1 to 3 inches (2.5 to 7.5 centimeters) in height as you age. You can help prevent height loss by following a healthy diet, staying physically active, and preventing and treating bone loss.

The dimensions of a rectangular garden are 15 yards by 20 yards. A sidewalk, one yard wide, is to be built around the outside of the garden. What will be the area of the sidewalk?
Answer:
74 square yards
Step-by-step explanation:
Area of two-dimensional shapes:Area of rectangular garden:
l = 20 yds
w = 15 yds
Area of the rectangular garden = l *w
= 20 * 15
= 300 square yards.
Area of the outer rectangle (rectangular garden and the sidewalk):
length = 20 + 1 + 1 = 22 yds
width = 15 + 1 + 1 = 17 yds
Area of outer rectangle = 22 * 17
= 374 square yards
To find the area of the sidewalk, subtract the area of rectangular garden from the outer rectangle.
Area of the sidewalk = area of outer rectangle - area of sidewalk
= 374 - 300

which polynomial function has a leading coefficient of 1 and roots (7+i) and (5-i) with multiplicity 1?
The polynomial function which has a leading coefficient 1 is (x-(7+i))(x-(5-i))(x-(7-i))(x-(5+i))
Given that a polynomial function has leading coefficient 1 and roots (7+i) and (5-i) with multiplicity 1.
We want to find the polynomial function.
As we know that the complex conjugate properties of the roots of a polynomial states that if a+bi is a root of a polynomial then their complex conjugate a-bi is also a root.
So, according to this property (7-i) and (5+i) with multiplicity 1 is also a root of polynomial.
Thus, all the roots are x=7+i, x=7-i, x=5+i and x=5-i
So, the polynomial is f(x)=(x-(7+i))(x-(5-i))(x-(7-i))(x-(5+i))
Hence, the polynomial function which has a leading coefficient 1 and roots (7+i) and (5-i) is (x-(7+i))(x-(5-i))(x-(7-i))(x-(5+i)).

p is the maximum total profit that can be made.
Step-by-step explanation:
See the attached worksheet for additional explanation. The question asks for the meaning of s (selling price) and p (total profits) at the vertex of the curve. s is in units of price/laptop, while p is in units of total profits. Implicit in this graph is a demand curve (not shown) that illustrates how demand for laptops changes as the price changes. Also not shown, but assumed, is that if the laptops are sold at a low price, the declining profit margins resuce the overall total profits. This graph incorporates the cost and demand imformation in a manner that provides a condensed view of the more important variable: total profits.
two equal rectangular lots are enclosed by fencing the perimeter of a rectangular lot and then putting a fence across its middle. if each lot is to contain 300 square feet, what is the minimum amount of fence (in ft) needed to enclose the lots (include the fence across the middle)?
The minimum amount of fence needed to enclose the lots is 120ft.
Adding areas of both fields, the combined area comes about to be 600sq ft.
The dimensions of the new plot are x length and y breadth. According to the question, there is a fence in the middle with y breadth.
g(x, y, z) = xy - 600
g(x, y, z) = 2x + 3y
∇g = ∇ (xy - 600) = (y, x)
∇f = ∇(2x + 3y) = (2, 3)
Now from the Lagrange method,
∇f = λ∇g
2 = λy
3 = λx
Now to get the value of lambda,
(2/y) = (3/x) = λ
x = 1.5y
Solving now we get,
1.5y² = 600
y = 20
x = 1.5 × 20 = 30
Thus after getting (x,y) we can put the value in the function to get the answer as 120ft.

A store owner bought dog bowls for $6 and sold them for $8.10. What is the mark-up, as a percentage?
Answer:I am not fully going to do it for you, but here is the best way i can explain, it if not i am sorry.
Step-by-step explanation: Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.
