A linear function is one that visualizes a straight line on the coordinate plane.
What is a linear function?When the independent variable (often 'x') varies by a constant amount and the dependent variable (typically expressed by 'y') changes by a constant amount, the function is said to be linear. A linear function is, for instance, the progression in the number of ticks of a clock's second hand through time.
Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 indicates a straight line on a coordinate plane, indicating that it is a linear function. This function can be expressed as f(x) = 3x - 2 since f(x) can take the place of y.

What are polynomial functions?
Polynomial is made up of two words, poly and nomial. "Poly" means many, and "nomial" means the term, and hence when they are combined, we can say that polynomials are "algebraic expressions with many terms"
Polynomial functions are expressions that may contain variables of varying degrees, coefficients, positive exponents, and constants. for e.g.
f(x) = 3x^2 - 5.
Types of Polynomial Function:
Constant Polynomial Function - A constant polynomial function is a function whose value does not change. It remains the same and also it does not include any variables.
Zero Polynomial Function - Polynomial functions with a degree of 0 are known as zero Polynomial functions.
Linear Polynomial Function - Polynomial functions with a degree of 1 are known as Linear Polynomial functions.
Quadratic Polynomial Function - Polynomial functions with a degree of 2 are known as Quadratic Polynomial functions.
Cubic Polynomial Function - Polynomial functions with a degree of 3 are known as Cubic Polynomial functions.

The equation in slope-intercept form is y = (-2/5)x - 9/2.
What is slope-intercept?Slope-intercept form is an equation of a line that is written in the form of y=mx+b, where m is the slope of the line and b is the y-intercept. The slope-intercept form makes it easy to identify the slope and y-intercept of a line from an equation.
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Therefore, for a line with a slope of −2/5 that passes through the point (15, −9/2), we can solve for b using the point-slope formula.
Point-slope formula: y - y1 = m(x - x1)
Plugging in the given information, we get:
-9/2 - (-9/2) = (-2/5) (15 - 15)

Rashid travels 240km from Abu Dhabi to Sharjah driving 120km/h for 2 hours. His parents strongly suggest he slow down by v km/h, even though it will take him t hours longer to make the trip, or he will lose his driving privilege. Which relation shows time, t, it will now take Rashid to make the trip relative to the speed, v with which he slows down?
The expression that shows time, t, it will now take Rashid to make the trip relative to the speed, v with which he slows down is t = (240 - (v/120) * 240) / (120 - v)
How to illustrate the speed?Speed is the rate at which an object's location changes in a particular direction. The distance traveled on relation changes to a particular direction. The distance in relation to the time it took to travel the distance is the speed. It's a scalar quantity.
The relation between time, t, and the speed at which Rashid slows down, v, is given by the formula:
t = (240 - (v/120) * 240) / (120 - v)
t = time
v= speed.

Another one of Carla’s friends suggests that she make the sample larger and survey 100 students. Which sample size is more likely to represent the population? Explain.
In general, a larger sample size is more likely to represent the population than a smaller sample size. This is because a larger sample size increases the chances that the sample will be representative of the population.
what is sample size?When the sample size is that larger, there is a lower chance of getting a skewed or biased sample. A larger sample size also tends to have less variability in the sample statistics, making it more likely to provide accurate estimates of population parameters.
However, it is important to note that increasing the sample size does not guarantee that the sample is representative of the population. The sampling method used, and the way the sample is selected, can also have an impact on the representativeness of the sample.
Hence, surveying 100 students is more likely to represent the population than surveying a smaller sample size like 10 students, but it does not guarantee a perfect representation of the population.

What are dilation rules?
Dilation rules refer to the mathematical rules and formulas used to calculate the image of a point, shape, or figure after it has undergone a dilation transformation.
Here are some of the most common dilation rules:
Scale Factor: The scale factor is the ratio of the length of a line segment in the image to the length of the corresponding line segment in the pre-image. For example, a dilation with a scale factor of 2 will double the length of the line segment.Center of Dilation: The center of dilation is a fixed point in the plane that remains the same distance from all points on the image and the pre-image. The center of dilation is used as a reference point to determine the new coordinates of the image. Distance Formula: To find the image of a point after dilation, the distance formula can be used. The distance formula calculates the distance between two points in the plane. Ratio: The ratio of the distance between two points on the pre-image to the distance between the corresponding points on the image is equal to the scale factor.Similarity: When dilation is done with a scale factor greater than 1, the image and pre-image figures are similar. Congruence: When dilation is done with a scale factor equal to 1, the image and pre-image figures are congruent.It's important to note that, the rules mentioned above are general rules of dilation and they might vary depending on the specific dilation transformation.

For the fixed base(10), if the exponent decrease by 1, the number will becomes one-tenth of the previous number.
What are the rules of exponents?The Power Rule for Exponents is (a^m)^n = a^m*n. To increase a number with an exponent to a power, we need to multiply the exponent times the power. Negative Exponent Rule is x^-n = 1/x^n. We need to invert the base to change a negative exponent into a positive.
Exponents are used to represent repeated multiplication of a number by itself. For example, 7 * 7 * 7 can be showed as 73. Here, the exponent is 3 that stands for the number of times the number 7 is multiplied. The base here is 7 that is the actual number which is getting multiplied.

An acute triangle is a triangle with all three angles less than 90 degrees.
An example of an acute triangle is a triangle with angles measuring 30 degrees, 55 degrees, and 95 degrees. Using the Law of Cosines, we can calculate the side lengths of this triangle. The side opposite the 30 degree angle is 4.8, the side opposite the 55 degree angle is 5.2, and the side opposite the 95 degree angle is 8. The Law of Cosines states that the following equation must be true: a2 = b2 + c2 - 2bc Cos A. In this case, a2 = 82, b2 = 52, and c2 = 42. We can then solve for the sides of the triangle by plugging in the values for a2, b2, and c2 into the equation. The result is that the side lengths of this triangle are 4.8, 5.2, and 8.

The average rate of change of the given function is 20.
What is the average rate of change of the function?It quantifies how much the function changed per unit on average throughout that time interval. The slope of the straight line connecting the interval's ends on the function's graph is used to calculate it.
The average rate of change of a function f(x) over the interval [a,b] is given by the formula:
(f(b) - f(a)) / (b - a)
So, for the function f(x) = x² + 2 as x changes from 5 to 15, we can plug in the values to find the average rate of change:
(f(15) - f(5)) / (15 - 5) = (15² + 2 - 5² - 2) / (15 - 5) = (225 - 25) / 10 = 200 / 10 = 20
