The graph of the linear function is choice B.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

We have been given the linear function as;

y = −5x − 3

Here we can see that the slope of the given equation is -5.

Also the intercept of the function is -3.

If August 17 is a Sunday, then the first of September will be a Monday.

First, we need to count the number of days between Agust 17 and September 1.

We know that August has 31 days, so between Agust 17 and September 1 there are:

31 - 17 = 14

And adding the other day until September 1, we have 15 days.

So there are 15 days between August 17 and September 1, and we know that the days have a pattern in a period of 7 days.

So, 7 days after August 17, is Sunday again.

Another 7 days (for a total of 14) Is Sunday again.

Adding the last day (total of 15) is Monday.

So we conclude that the first of September will be a Monday.

Answer:

D   21.80°

Step-by-step explanation:

Let x = measure of the angle

Tan x = 12000/30000 = .4

Arctan .4 = 21.80°

∆ABC=∆DEF

AB=DE –>String

BC=EF–> Rib

m<C=m<F=90° –>List

AC=DF

So m<A=m<D=35 (It is not clear whether the number is 35 or 36, but the same number)

The inverse of the given function is, \(f^-^1(x) = \sqrt{x+4} +1\).

What is inverse of the function?

A function that can reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f^-1" or "F^-1."

Consider, the given function

f(x) = (x - 1)^2 - 4

We have to find inverse of the function.

Let  y = (x - 1)^2 - 4

Replace x with y in the above equation.

x = (y - 1)^2 - 4

Add 4 on both sides,

x + 4 = (y - 1)^2

Taking square root on both sides,

\(\sqrt{x+4} = y - 1\)

Add 1 on both sides,

\(\sqrt{x+4}+1 = y\)

\(y = \sqrt{x+4} + 1\)

Take \(y = f^-^1(x)\)

⇒ \(f^-^1(x) = \sqrt{x+4} + 1\)

Hence, the inverse of the given function is, \(f^-^1(x) = \sqrt{x+4} +1\).

The experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is approximately 0.263

The experimental probability is found by dividing the number of times the desired outcome occurred by the total number of trials. In this case, the desired outcome is selling a slice of pepperoni pizza as the first slice tomorrow.

Since we only know the number of slices sold today, we don't have any specific information about the number of slices that will be sold tomorrow. However, we can assume that the same types of pizzas will be sold tomorrow, and the probability of selling a slice of pepperoni pizza tomorrow will be the same as the proportion of pepperoni slices sold today.

So, the experimental probability that the first slice sold during lunch tomorrow will be a slice of pepperoni pizza is

Experimental probability = Number of pepperoni slices sold today / Total number of slices sold today

Experimental probability = 20 / 76

Experimental probability = 0.263

The local hour angle of Sirius when the local sidereal time is 03h 00m is approximately -56.25 degrees.

To find the local hour angle of Sirius, we need to determine the difference between the local sidereal time and the right ascension of Sirius. The local sidereal time represents the hour angle of the vernal equinox, which is the point in the sky where the Sun crosses the celestial equator from south to north during the spring equinox.

We have,

Right Ascension of Sirius = 06h 45m

Declination of Sirius = -16° 43'

First, we need to convert the right ascension of Sirius into degrees. Since there are 24 hours in a full circle, each hour corresponds to 15 degrees (360°/24h). Each minute of right ascension corresponds to 0.25 degrees (15°/60m).

Right Ascension of Sirius in degrees:

= (6 hours * 15 degrees/hour) + (45 minutes * 0.25 degrees/minute)

= 90 degrees + 11.25 degrees

= 101.25 degrees

Next, we need to convert the local sidereal time into degrees. Since there are 24 hours in a full circle, each hour corresponds to 15 degrees.

Local Sidereal Time in degrees:

= 3 hours * 15 degrees/hour

= 45 degrees

Finally, we can calculate the local hour angle of Sirius by subtracting the right ascension of Sirius from the local sidereal time.

Local Hour Angle of Sirius:

= Local Sidereal Time - Right Ascension of Sirius

= 45 degrees - 101.25 degrees

= -56.25 degrees

The local hour angle of Sirius when the local sidereal time is 03h 00m is approximately -56.25 degrees.

Given parameters:

Midpoint of AB =  M(3, -1)

Coordinates of A = (5,1)

Unknown:

Coordinates of B = ?

Solution:

To find the mid point of any line, we use the expression below;

              \(x_{m} = \frac{x_{1} + x_{2} }{2}\)    and \(y_{m} = \frac{y_{1} + y_{2} }{2}\)

where \(x_{m}\)  and \(y_{m}\) = coordinates of the mid points = 3 and -1

   x₁  = 5 and y₁ = 1

  x₂ = ?  and y₂ = ?

Now let us input the variables and solve,

            3  = \(\frac{5 + x_{2} }{2}\)           and     -1 = \(\frac{1 + y_{2} }{2}\)

    5 +  x₂  = 6                          -2 = 1  + y₂

            x₂ = 1                             y₂ = -2 -1 = -3

The coordinates of B = 1, -3

Functions are mathematical algorithms used to generate message summaries or digests for verifying message identity and content integrity.

Functions, in the context of cryptography and information security, are mathematical algorithms that play a crucial role in generating message summaries or digests. These digests are commonly referred to as hash values or fingerprints. The primary purpose of using functions is to confirm the identity of a specific message and ensure that the content has not been altered.

A hash function takes an input message of any length and applies a series of mathematical operations to produce a fixed-length output, typically represented as a sequence of alphanumeric characters. This output is unique to the input message, meaning even a slight change in the message would result in a significantly different hash value. By comparing the generated hash value with the originally computed one, it is possible to determine if the message has remained intact or if any tampering has occurred.

The use of functions in message verification provides a practical and efficient way to ensure data integrity and authenticity. It enables recipients to confirm that the received message matches the originally transmitted one, providing assurance against unauthorized modifications or tampering. Functions are widely utilized in various security protocols, such as digital signatures, integrity checks, and secure communication channels, to enhance the overall security of information systems.

so,

A^3 +B^3 + C^3 = 3 ABC

now we put the values

\({(a - b)}^{3} + {(b - c)}^{3} + {(c - a)}^{3} = 3(a - b)(b - c)(c - a)\)
