definition of a tangent?

Answer:

f(x) = 16*0.75^x

Step-by-step explanation:

first off let's use this coordinate (the one given) :

(0,16)

let's substitute this into the equation with x being 0 and f(x) being 16

16 = a*b^0

*anything to the power of 0 is 1*

so:

a = 16

now use the second coordinate :

(1,12)

and do the same by substituting 1 for x and 12 for f(x), we also know what 'a' is:

12 = 16*b^1

12 = 16 * b

b = 3/4

so :

f(x) = 16*0.75^x

The average of given numbers is equal to the sum of all the values divided by the total number of values. It  generally refers to a measure of central tendency or the typical value within a set of data points.

The mean, or arithmetic mean, is the most commonly used type of average. It is calculated by adding up all the values in a data set and dividing by the total number of data points. Mathematically, the mean is represented as:

Mean = (Sum of all values) / (Total number of data points)

The slope of a line given the table is equal to 0.

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = rise/run

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given data points into the slope formula, we have the following;

Slope (m) = (9 - 9)/(3 - 1)

Slope (m) = 0/2

Slope (m) = 0.

Based on the table, the slope is the change in y-axis with respect to the x-axis and it is equal to 0.

The probability of the TPMS triggering a warning is 0.0198 or about 0.02, rounded to four decimal places.

It is used to predict and estimate the likelihood of future events and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Let's assume that the tire pressure follows a normal distribution with a mean of 32 psi and a standard deviation of 3 psi.

Let's also assume that the TPMS warning is triggered when the tire pressure falls below 25 psi or rises above 39 psi.

Using a standard normal distribution table or calculator, we can find the z-scores corresponding to 25 psi and 39 psi:

z₁ = (25 - 32) / 3 = -2.3333

z₂ = (39 - 32) / 3 = 2.3333

Then, we can find the probabilities associated with these z-scores:

P (z < -2.3333) = 0.0099

P (z > 2.3333) = 0.0099

The total probability of the TPMS triggering a warning is the sum of these two probabilities:

P(TPMS warning) = P(z < -2.3333) + P(z > 2.3333) = 0.0099 + 0.0099 = 0.0198

Therefore, the probability of the TPMS triggering a warning is 0.0198 or about 0.02, rounded to four decimal places.

To find the answer, we can use the formula for combinations:

nCr = n! / r!(n-r)!

where n is the total number of games, r is the number of losses, and n-r-1 is the number of ties (since we already know there are 9 wins).

Substituting the values, we get:

13C3 * 10C1

= (13! / 3!10!) * (10! / 1!9!)

= (13*12*11 / 3*2*1) * 10

The total number of students surveyed (240) goes in blank 9, where row and column headings are both "Total".

The number 35% × 240 = 84 goes in blank 7, the total number interested in athletics.

The number 3/5 × 240 = 144 goes in blank 3, the total number interested in academic clubs.

The number 26 goes in blank 1, which is in row 1 (interested in academic clubs) and in column 1 (interested in athletics). It is the number interested in both.

Blank 2 is the difference between blank 3 and blank 1. It makes the total for the line be correct.

Blank 4 is the difference between blank 7 and blank 1. It makes the total for the column be correct.

The graph is not a function

To qualify as a function, any input (x-value) of a graph must be linked to a single output (y-value). Therefore, each x-value ought to have one and only one y-value that matches it.

A method for identifying whether or not a given graph is representative of a function is by conducting a vertical line test. To achieve this, vertically draw lines through the graph. When every vertical line hits the graph at just one point, then the illustration aptly presents a function. Conversely, if the graph forms multiple intersection points with any vertical line, it isn't classified as a functional representation.

[tex]f(x) = x^2 + 6x - 7[/tex] is the equation of the function.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

To find the equation of the quadratic function, we need to use the vertex form of the equation:

[tex]f(x) = a(x - h)^2 + k[/tex]

where (h, k) is the vertex of the parabola.

We know that the vertex is (-3, 16), so h = -3 and k = 16. We also know that the x-intercepts are at -7 and 1, which means that the factors of the quadratic function are (x + 7) and (x - 1).

To find the value of 'a', we can use either of the x-intercepts:

[tex]f(-7) = a(-7 + 3)^2 + 16 = 0\\\\16a = 16\\\\a = 1[/tex]

Therefore, the equation of the quadratic function is:

[tex]f(x) = (x + 7)(x - 1)\\\\f(x) = x^2 + 6x - 7[/tex]

To subtract 47.96 from 320.041, you can align the decimal points and then subtract each digit from right to left.

First, write the numbers with the decimal points aligned:

320.041

- 47.960

Next, subtract the digits in the ones place, which is 1 minus 0, resulting in 1. Then, subtract the digits in the tenths place, which is 4 minus 6. Since 4 is less than 6, you need to borrow 1 from the digit to the left, making the 2 into a 1 and adding 10 to the 4, giving you 14. So, 14 minus 6 equals 8.

Continue subtracting each digit in the same way:

   320.041

Trigonometric identities are mathematical equations that may be used to express trigonometric functions. These identities, which are also used to solve trigonometric equations, can be utilised to simplify and manage trigonometric expressions.

Trigonometric identities, which are derived from the geometric properties of triangles and the unit circle, provide a way to describe trigonometric functions in terms of other trigonometric functions or constants.

The actual distance between the two cities is equal to 288 miles.

In Geometry and Mathematics, a scale factor simply refers to the ratio of two corresponding side lengths in two similar geometric figures, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.

In Geometry, the scale factor of a geometric figure can be calculated by dividing the side lengths of the image by the side lengths of the pre-image:

Scale factor = length of image (new figure)/length of pre-image (actual figure).

Scale:

0.25 inch = 24 miles

0.25/24 = New distance/Actual distance

0.25/24 = 3/Actual distance
