brian is splitting 4 quarts of ice cream with members of the team. If the ice cream is split evenly, how many cups will each person get
Each person will get 1 [tex]\frac{7}{9}[/tex] cups of ice cream.
What is Division?Division is one of the operation in mathematics where number is divided into equal parts as that of a definite number.
Given that, Brian is splitting 4 quarts of ice cream with members of the team.
Assume the number of members of the team = 9
We have to find how many cups each member gets.
First we have to convert the measurement quarts to cups.
1 quart = 2 pints
1 pint = 2 cups
1 quart = 2 × 2 cups = 4 cups
We have 4 quarts of ice cream.
4 quarts = 4 × 4 = 16 cups
Number of cups each member gets = 16/9 cups = 1 [tex]\frac{7}{9}[/tex] cups
Hence there will be 1 [tex]\frac{7}{9}[/tex] cups for each member.

Richard and Teo have a combined age of 36. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Teo is 10.5 years old and Richard is 25.5 years old.
How old are Richard and Teo?Represent Teo's age with x.
Using the above as a guide, we have the following:
Richard = x + 15
Their combined age is 36
So, we have the following representation
x + (x + 15) = 36
Evaluate the like terms
2x + 15 = 36
2x = 21
x = 10.5
Recall that

A function for which the range remains the same, and reciprocal values of the domain are used
The requried, inverse of a function is a function for which the values or the domain and the range are interchanged. Option C is correct.
What is an inverse function?The inverse of a function is a new function that results from interchanging the input (domain) and output (range) of the original function.
Here,
if f(x) is a function, its inverse function is denoted by f⁻¹(x), and it is defined such that f⁻¹(y) = x, where y = f(x) is the original function.
For example, if f(x) = 2x + 3, the inverse function f⁻¹(x) is found by interchanging x and y, and solving for y:
x = 2y + 3
2y = x - 3
y = (x - 3)/2
Therefore, f⁻¹(x) = (x - 3)/2, and it is the inverse of the original function f(x). Note that the domain and range of the inverse function are interchanged with respect to the original function.

China’s steel production is increasing while its major competitors’ production is declining.

At 50 tons of steel produced per US million ($) GDP, China has the highest steel production of all producers shown as of 2009.

Here,
The most accurate comment about the data is: "China's steel production is increasing while its major competitors' production is declining."
This is because the graph shows that China's steel production has been steadily increasing since the early 2000s, while the steel production of other major producers such as Japan, the United States, and Germany has been declining or stagnant. This trend is particularly evident after the global financial crisis of 2008-2009.
While it is true that Japan's steel production has increased and shows no signs of decreasing, this comment does not address the overall trend of declining steel production among major producers.
The other two comments are not accurate. The statement "By 2009, China’s tons of steel produced per US million ($) GDP was 50, about 10 tons less than Japan’s all-time high" is not supported by the graph, as there is no information about tons of steel produced per US million ($) GDP on the graph.

write an exponential function that has a y-intercept of -4 and passes through the points (1, -1.6) and (2, -0.64)
The function can be used to model the exponential growth or decay that occurs in real-life situations that fit this particular pattern is y = 4(-0.4)ˣ + -4
An exponential function is a mathematical function that has the form
=> y = abˣ,
where a is a constant and b is the base of the exponential.
To start, we will use the first point, (1, -1.6), to write an equation that relates x and y. Let's call the constant a in our exponential function "k". Using the point (1, -1.6), we can write the equation:
=> -1.6 = k * b¹
Next, we will use the second point, (2, -0.64), to write another equation that relates x and y. Using the point (2, -0.64), we can write the equation:
=> -0.64 = k * b²
Now that we have two equations, we can solve for the two unknowns, k and b, by dividing the two equations:
=> (-0.64) / (-1.6) = k * b² / k * b¹
b = (0.64 / -1.6)¹
b = -0.4
With b determined, we can substitute it back into one of the equations and solve for k:
=> -1.6 = k * (-0.4)¹
=> k = -1.6 / (-0.4)
=> k = 4
So our exponential function that passes through the points (1, -1.6) and (2, -0.64) and has a y-intercept of -4 is:
y = 4 * (-0.4)ˣ + -4

A salesperson earned a commission of
$806.59
last week on gross sales of
$5880
. If returns and allowances were 11.5% of gross sales, what is his rate of commission based on net sales?
Using percentages we know that the rate of commission of the salesperson based on the net sales is 15.5%.
What are percentages?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and sometimes "pc" is also used, the percent symbol, "%," is frequently used to indicate it.
A % is a number without boundaries and without a standard measurement.
So, calculate as follows:
5880/100 * 11.5 = 676.2
Now,
5880 - 676.2 = 5,203.8
Now, calculate the percentage as follows:
806.59/5,203.8 * 100
15.5%

How to use rigid transformations on functions
In this problem we find four cases of functions that must be transformed by rigid transformations. Rigid transformations are transformations applied on functions such that its features are not altered. We should apply, if possible, the following rigid transformations:
Reflection across the y-axis
f(x) → f(- x)
Translation to the right
f(x) → f(x - k), where k > 0
Translation downward
f(x) → f(x) - k, where k > 0
Now we proceed to determine the image of each function:
Case 1
f(x) = √x
Reflection across the y-axis
f(x) = √(- x)
Case 2
Translation 4 units right
f(x) = √(x - 4)
Case 3

The intersection points are (6, 6) and (-6, -6).
What is Intersection points?
The point at which two lines or curves intersect is referred to as the point of intersection. The point at which two curves intersect is crucial because it is the point at which the two curves take on the same value.
The given curves are the polar equations of two circles with radii 6. To find their intersection points, we can set the two equations equal to each other and solve for Ф.
6 sin(Ф) = 6 cos(Ф)
Dividing both sides by 6 and rearranging terms, we get:
tan(Ф) = 1
This equation has infinitely many solutions, but we are only interested in those that lie in the interval [0, π/2].
Ф = π/4 satisfies this condition and corresponds to the point (6, 6) in Cartesian coordinates.
Since the two curves are circles, they are symmetrical about the origin. Therefore, we can deduce that the other intersection point is (-6, -6).
Therefore, the intersection points are (6, 6) and (-6, -6).
