Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.
What is the Rate of Change/Slope of a Function?Another name for the rate of change of a function is the slope. It is calculated using the formula:
Slope / rate of change = change in y / change in x.
If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".
Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.
To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):
Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1
m = -1.
The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.

Answers
Based on the values you've listed, it appears that the expression P(7, 5) represents a combination calculation. In combinatorics, the notation P(n, k) represents the number of ways to choose a subset of k items from a set of n items, without regard to the order in which the items are chosen. This is also known as the number of k-permutations of n items.
In this case, the expression P(7, 5) would represent the number of ways to choose a subset of 5 items from a set of 7 items. Using the formula for combinations, this would be calculated as follows:
P(7, 5) = 7! / (5! * (7 - 5)!)
= 7! / (5! * 2!)
= 7 * 6 * 5 * 4 * 3 / (5 * 4 * 3 * 2 * 1 * 2 * 1)
= 7 * 6 / 2
= 21
Therefore, the correct answer for the expression P(7, 5) is 21.
Warner received 7 letters. Each letter weighed between 3.92 ounces and 4.1 ounces. Warner estimates a reasonable weight of all the letters to be 30 ounces.
Is this a reasonable estimate?
Answers
The estimate made by Warner is 95% reasonable.
What is inequality? What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Warner received 7 letters and each letter weighed between 3.92 ounces and 4.1 ounces.
If the we take the maximum possible weight of each letter, which is 4 ounces, then the total weight of 7 letters will be equal to (4 x 7) = 28. But since the weights are weighted between 3.92 ounces and 4.1 ounces, let us assume that the weight of each letter is equivalent to -
w(a) = (3.92 + 4.10)/2 = 8.02/2 = 4.01
So, the weight of 7 letters would be -
W{7} = w(a) x 7 = 7 x 4.01 = 28.7
28.7 = 29 (round off) ≈ 30
So, yes the estimate of the Warner is reasonable.
Therefore, the estimate made by Warner is 95% reasonable.

a coin is tossed and a die is rolled. find the probability of getting a head and a number greater than 5
Answers
The probability of getting a head and a number greater than 5 i.e, independent events is 0.0833.
A coin is tossed and a die is rolled. These are two independent events. Two events are defined as independent if the outcome of one event has no effect on the outcome of another event. The probability is calculated by multiplying two independent probabilities together, i.e, P(A and B) = P(A) x P(B)
We have, Let us assume two independent events be ,
A : A coin is tossed and the head is thrown.
B : A die is rolled, and a number greater than 5 occurs.
Total possible outcomes when a coin tossed = 2 ={ H ,T }
Total possible outcomes when a die rolled = 6 = { 1,2,3,4,5,6} .
We have to determine probability of getting a head and a number greater
than 5.
Probability of getting the head on toss a coin, P(A) = 1/2
Probability of occuring a number greater than 5 on rolling a die = P(B) = 1/6
So, the probability of getting a head on coin and a number greater than 5 on die =P(A)×P(B)
=(1/2)× 1/6 = 1/12=0.0833
Hence, required probability is 0.0833.

Find the measures of two complementary angles if the measure of the larger angle is 2 less than 3 times the measure of the smaller angle.
Answers
Answer:
Let x be the larger angle and y be the smaller angle
Larger angle is 2 less than 3 times the smaller angle that is x = 3y - 2
As the angles are complementary, their sum equals 90°
or, x + y = 90°
or, 3y - 2 + y = 90°
or, 4y = 92°
or, y = 23°
So, x = 3 * 23 - 2 = 67°
Larger angle = x = 67°
Smaller angle = y = 23°

the radius of a spherical ball is increasing at a rate of . at what rate is the surface area of the ball increasing when the radius is cm?
Answers
Although part of your question is missing, you might be referring to this full question: The radius of a spherical ball is increasing at a rate of 2 cm/min. At what rate is the surface area of the ball increasing when the radius is 8 cm? The surface area of a sphere with radius r is given by 4πr².
The rate at which the surface area of the ball increasing when the radius is 8 cm is 128 cm²/min.
Given A = 4πr²
So, we have:
dA/dt = d/dt (4πr²)
= 4π * d/dt * (r²)
= 4π * 2r * dr/dt
= 8πr * dr/dt
Now, we have that dr/dt = 2 cm/min. So, when the radius of the ball is 8 cm, we have that:
dA/dt = 8πr * dr/dt
= 8π * 8 * 2
= 128π
Since we are measuring area, our unit is cm²/min, not cm/min.
Thus, the rate at which the surface area of the ball increasing when the radius is 8 cm is 128 cm²/min.

Labels on a line graph can make the visualization more accessible in a few ways:
Labels can provide additional context for the data. For example, if the y-axis of the line graph represents the temperature in degrees Celsius, labeling each line with the location or type of temperature measurement can help the viewer better understand the data.Labels can help the viewer more quickly identify the data they are interested in. If the line graph has many lines and a legend, it can be time-consuming to locate the specific line of interest. By labeling each line directly on the graph, the viewer can more easily find the data they are looking for.Labels can improve the clarity and readability of the graph. If the lines on the graph are close together or overlap, labels can help the viewer distinguish between the different lines.Overall, labels can help make a line graph more accessible by providing additional context, improving readability, and helping the viewer quickly find the data they are interested in.
