Answer:
x^12 + 9x^4 - 9x^3 - 18
Step-by-step explanation:
When there is a circled in black dot in the middle of f and g, then it means to multiply. Using the distributive property and the FOIL method, the answer should be x^12 + 9x^4 - 9x^3 - 18.

The domain of a function is the set of x values for which it is defined. The correct option is D.
What is the domain and range of a function?The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.
To find the domain of the function it needed to be simplified. Therefore, the function can be rewritten as,
[tex]f(x) = \dfrac{3x}{4x^2-4}\\\\f(x) = \dfrac{3x}{4(x^2-1)}[/tex]
As it can be seen that for the fraction of the value of x is kept -1 or 1, then the denominator of the function will become zero, which is undefined.
Hence, the domain of the given function is all real numbers except x = –1 and x = 1.

kala is in charge of planning a reception for 3400 people. she is trying to decide which snacks to buy. she has asked a random sample of people who are coming to the reception what their favorite snack is. Here are the results Brownies for 54 people, pretzels for 56 people potato chips for 52 people other for 63 people. based on the above sample predict the number of the people at the reception whose favorite snack will be brownies. round your answer to the nearest whole number. do not round any intermediate calculations
Answer:
816
Step-by-step explanation:
Find total number of people asked by adding all the people.
54 + 56 + 52 + 63 = 225
So, 54 out of 225 people have their favorite snack as brownies.
We need to find out how many it is for 3,400. We can do that by cross multiplying.
54 = x (did it like this so it's better visually)
225 3400
Multiply both sides by 3,400 and divide to get:

which estimator will consistently have a skewed sampling distribution?
A.) coefficient of variation
B.) median
C.) standard deviation
D.) variance
Answer:
other duds wrong its d variance
Step-by-step explanation:
im 100% sure
The correct answer is option (C) Standard Deviation.The estimator that consistently has a skewed sampling distribution is the standard deviation, especially when the original data is non-symmetric or skewed.
Among the given options, the estimator that will consistently have a skewed sampling distribution is the standard deviation. When estimating the standard deviation from a sample, the resulting distribution does not always follow a normal pattern, especially if the original data is skewed. The standard deviation is calculated using each data point's deviation from the mean, which can lead to skewed results in non-symmetric distributions.
For instance, in a skewed distribution with extreme values, the mean and subsequently the standard deviation can be disproportionately influenced by those extremities, hence failing to accurately reflect the spread of the majority of the data. Therefore, sometimes measures like the median, which is not as sensitive to outliers, are considered better representations of the central tendency in a skewed data set.
Additionally, the standard deviation is meaningful for symmetrical distributions, while skewed distributions require a consideration of other measures such as the modes, medians, or quartiles. When presented with data, always visualize it using a histogram or a box plot to better understand the distribution.

M-line is a company that prints and sells custom designs on t shirts. For each order, they charge an initial design fee and then an additional fee for each printed t shirt. M- line charges M euros per order. This charge is modeled by the lunar function M (x) = 5x + 40, where x is the number of t shirts in the order. Write down the initial design fee charged for each order.
Answer:
The initial design fee charged per order is 40
Step-by-step explanation:
From the question, we are told that the company charges an initial design fee then additional fee for each printed t shirt
Therefore, if the cost of an order is y, we have;
y = m·x+i
Where:
i = Initial design charge
m = additional fee for each printed shirt
x = number of shirts
Comparing the above equation with the given equation we have
y = m·x + i
M (x) = 5·x + 40
Hence, where M(x) = y = Charge per order, then it is noted that the coefficient of x is the additional fee per printed shirt, therefore, the initial design fee charged per order, i is equivalent to 40
Hence the initial design fee charged per order = 40.

Rate of change:
Slope of a line is the rate of change. Slope of a line tells us the steepness of the line. Equation of a line of the form y=mx+b
where m is the slope that is the rate of change.
Find the rate of change from each equation
[tex]y=\frac{3}{4}x-10\\slope =\frac{3}{4}\\\\y=\frac{3}{2}x+\frac{11}{2}\\slope =\frac{3}{2}\\\\y=\frac{1}{2}x-2\\slope =\frac{1}{2}\\\\y=\frac{5}{2}x+10\\slope =\frac{5}{2}\\[/tex]
Now we compare all the slopes
Slopes are the rate of change
[tex]slope =\frac{3}{4}\\ slope =\frac{3}{2}\\slope =\frac{1}{2}\\ slope =\frac{5}{2}\\\\\frac{1}{2} < \frac{3}{4} < \frac{3}{2} < \frac{5}{2}\\[/tex]
The function from least to greatest rate of change is

which equation describes the line with a slope of 5 and y-intercept of -3
answers :
y= -3x + 5
y= 3x - 5
y= 5x - 3
y= 5x + 3
The equation representing the line with the slope of 5 and y-intercept of -3 is y=5x-3. This answer is derived from substituting these values into the standard line equation y=mx+b.
Explanation:The equation of a line is generally given by the formula y=mx+b, where m is the slope of the line and b is the y-intercept of the line.
If the slope is 5 and the y-intercept is -3, and we plug these values into the standard formula, we get y=5x-3. Hence, the equation that describes the line with a slope of 5 and y-intercept of -3 is y=5x-3.

Solve for z-
-0.25z = -1.25
z = ___
Answer:
5
Step-by-step explanation:
The value of z in the equation -0.25z = -1.25 is simplified to z = 5.
To solve for z in the equation -0.25z = -1.25, we need to isolate z by performing the necessary operations.
We can start by dividing both sides of the equation by -0.25 to cancel out the coefficient of z:
-0.25z / -0.25 = -1.25 / -0.25
This simplifies to:
z = 5
Therefore, the value of z in the equation -0.25z = -1.25 is z = 5.

Given the following exponential function, what is the initial amount y 60(1.71)^x?
Answer:
60
Step-by-step explanation:
The initial y value can be found by setting x to 0. Anything to the power of 0 is 1, so 1.71^x when x is 0 is just 1. 60*1=60, which is the initial y value. Hope this helps!
The initial amount 'y' of the exponential function [tex]y = 60(1.71)^x[/tex] is 60. This value represents the function's y-intercept, the amount present before any exponential growth occurs.
The student has provided an exponential function and wishes to know the initial amount, which can be expressed as 'y' in the function [tex]y = 60(1.71)^x[/tex]. The initial amount when x=0 is the coefficient of the exponential term. For this function, when x equals 0,[tex](1.71)^0[/tex] is 1, since any number raised to the power of 0 is 1. Therefore, the initial amount or the y-intercept of this function is 60.
This value represents the starting quantity before any growth (or decay if the base were less than 1) has occurred in the context of the function. It is important to note that the base of the exponential function (1.71 in this case) indicates the rate of growth per unit increase of the variable x

see the attached figure to better understand the problem
therefore
It is congruent to Angle A P C
The True statement about <CPB is It is supplementary to angle APC.
The correct option is (B).
What is Supplementary Angle?In mathematics, the definition of supplementary relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another
It has an acute angle on one side and an obtuse angle on the other.The two angles are both right angles.The two angles do not have to be adjacent to form a straight line.As, when two angles that when added together equal 180 degrees is Supplementary Angle.
From the figure if we add <CPB and <APC forms the straight line gives the angle 180 degree.
i.e., <CPB + <APC = 180
or, <CPC= 180- <APC
So, <CPB is supplementary to angle APC.
