You are c) a structure. A structure is a collection of one or more different types of variables, including arrays and pointers, that have been grouped under a single name for each manipulation.

A structure is a user-defined data type that allows you to group together related data. For example, you could create a structure to store the name, age, and address of a person. The structure would have three variables, each of a different type: a string variable for the name, an integer variable for the age, and a string variable for the address.

The advantage of using a structure is that it allows you to treat the related data as a single unit. This makes it easier to manipulate the data and to pass the data to functions.

The other answer choices are incorrect. A template is a blueprint for creating a generic class or function. An array is a collection of elements of the same type. Local variables are variables that are declared within a function and that are only accessible within the function.

Option A is the correct answer. the 105° angle and angle 2 are alternate exterior angles so angle 2 must measure 105°. angles 1 and 2 are supplementary angles so angle 1 must measure 75°.

Two angles are called supplementary when their measures add up to 180° degrees. These angles form a straight angle when they are put together.

Angle 1 and angle 2 are supplementary if Angle1+Angle2= 180°.Thus, Angle 1 and Angle 2 are called "supplements" of each other.

Two angles that lie on opposite sides of the transversal and are placed on two different lines are called alternate exterior angles. These pairs of angles are always equal if the two given lines are parallel.

Two exterior angles that lie on two different lines cut by a transversal and are placed on opposite sides of the transversal are called alternate exterior angles.

Here,105 and ∠2 are alternate exterior angles, ∠2=105 degrees.

Angles 1 and 2 and supplementary

so 180 - ∠2 = ∠1

180-105=75.

∠1 =75 degrees.

Therefore, The Coordinates of the THIRD VERTEX is:  ( 5, -3 )

        Calculate the midpoint of the given vertices:

        MidPoint = ( -5 + 5/2,  3 + 3/2 )

        MidPoint = ( 0, 3 )

        Distance = √( -5 -5 )^2 + ( 3 - 3 )^2

        Distance = √( -10 )^2  +  (0)^2

        Distance = √100

        Distance =  10

        Side Length =  10/√3

        Side Length = 10/1.7

        Side Length = 5.88

        Height = √3/2  *  Side Length

        Height  = 1.7/2  *  5.88

        Height  =  5

Since the origin lies inside the triangle, The Third Vertex will have a Positive  X-Coordinate and a Negative Y-Coordinate.

       ( x, y )

        x  =  -5 + x/2

        y   =  3 + y/2

       x  =  5

       y  = -3

        Hence, The Coordinate  of the Third Vertex is:  ( 5, -3 )

Answer:

A step function is described by the situation

Step-by-step explanation:

I just did it on edge

The absolute extrema of the function f(x, y) = -3x², defined by x² + y² ≤ 16, are Absolute Maximum: 0 and Absolute Minimum: -48.

The function is f(x, y) = -3x² defined by x² + y² ≤ 16.

We can see that the domain of the function is bounded by the circle of radius 4 centered at the origin. Thus, we can obtain the maximum and minimum values of the function by finding its critical points on the boundary of the circle and at the center of the circle.

We use the method of Lagrange multipliers to find the absolute extrema of the function as follows.

We set the function g(x, y) = x² + y² - 16 as the constraint function since we have to find the absolute extrema of the function on the boundary of the circle x² + y² = 16.

Thus, the Lagrangian function L(x, y, λ) is given by L(x, y, λ) = -3x² + λ(x² + y² - 16)

Taking the partial derivatives of L with respect to x, y, and λ and equating them to zero, we obtain

-6x + 2λx = 0

=> x(2λ - 3) = 0

⇒ x = 0 or λ = 3/2-6y + 2λy = 0

=> y(2λ - 3) = 0

⇒ y = 0 or λ = 3/2x² + y² - 16 = 0

The possible critical points are (0, -4), (0, 4), (-4, 0), (4, 0), (0, 0).

Using the Second Derivative Test, we can conclude that (0, 0) is the point of absolute maximum since the second partial derivatives test is negative. Also, the point of absolute minimum is (-4, 0) or (4, 0) since the second partial derivatives test is positive in both points.

Thus, the absolute extrema of the function are as follows.

Absolute Maximum: f(0,0) = 0

Absolute Minimum: f(-4,0) = f(4,0) = -48

The required absolute extrema are as follows.

Absolute Maximum: 0

Absolute Minimum: -48

Therefore, the absolute extrema of the function f(x, y) = − 3x² defined by x² + y² ≤ 16 are Absolute Maximum: 0, and Absolute Minimum: -48.

It is crossing x - axis at \((-2,0)\)

then y-axis at \((0,-2)\) and

then again x - axis at \((2,0)\).

If we try to plot the graph, the graph will be like it comes down from the negative x axis side and then intersect x axis at \((-2,0)\), then intersects y axis at \((0,-2)\)  and then rises towards the right side (i.e. positive x axis) intersecting the positive x axis at \((2,0)\).

The value of k in the equation x^2+kx-6=0  with one root equal to 3 is -1.

What does root of a quadratic equation mean?

A quadratic equation has a variable squared (in our question, it was x2). The root of a quadratic equation tells us that when we plug in the root for x, the equation is equal to 0.

Given :  x^2+kx-6=0

We see k in the equation: x^2+kx−6=0. We know that if we had a value of x to plug into this equation, then we could just solve it for k. So let’s see if we can find a value for x satisfying the quadratic equation.

We know that the root of a quadratic equation tells us that if we plug in the value of the root for x, then the equation will equal 0. So let’s solve this question by plugging in x=−1 and then simplify the equation until we can solve for k, then compare k to −1.

x²+kx−6 = 0

3² + k·3 − 6 = 0

9 + 3k − 6 = 0

3 + 3k = 0

3k = −3

k = −1

Hence , the value of k in the equation x^2+kx-6=0  with one root equal to 3 is -1.

The distance between your house and the subway stop is 6

What is distance?

Distance is a numerical measurement of the amount of space between two points or objects. It is typically measured in units such as meters, kilometers, miles, or feet, and it can be calculated using various mathematical formulas depending on the context.

How to find nearest distance between two points?

To find the nearest distance between two points, you can use the distance formula, which involves finding the square root of the sum of the squared differences between the corresponding coordinates of the points.

According to the above information

d = sqrt((x2 - x1)² + (y2 - y1)²)

where (x1, y1) are the coordinates of the subway stop and (x2, y2) are the coordinates of your house.

Plugging in the values, we get:

d = sqrt((-3 - (-7))² + (4 - (-1))²)

d = sqrt(4² + 5²)

d = sqrt(16 + 25)

d = sqrt(41)

d ≈ 6.4

\(\boxed {12x + 2}\)

Step-by-step explanation:

Solve the following expression:

\(4(3x + 2) - 6\)

-Use Distributive Property:

\(4(3x + 2) - 6\)

\(12x + 8 - 6\)

-Combine like terms:

\(12x + 8 - 6\)

\(\boxed {12x + 2}\)

Answer:

\(12x+2\)

Step-by-step explanation:

The first step is to distribute the 4 to the parenthesis. This turns the equation into:

\((12x+8)-6\)

We can remove the parenthesis now. Also, now we combine like terms. There are no other variables in the equation, so we leave the 12x alone. Combine the +8 and the -6 to get +2. This leaves the equation at:

\(12x+2\)

Answer: x < 6

Step-by-step explanation: As you can see, the circle on the 6 is an empty circle, which means that it does not have an equal sign within it (the line thing that's under the sign) because if the circle is a full circle than it will have an equal sign within it, and if it's an empty circle than there will be no equal sign within it. And, the arrow is going to the left which means that it is a less than sign.

The approximate measure of angle YZX is 39.4°. Option(B) is the correct answer.

we know that

In the right triangle XYZ

\(tan(Y Z X)= \frac{opposite side angle YZX}{adjacent side angle YZX}\)

In this problem,

Opposite side angle YZX= XY = 12.4cm

Adjacent side angle YZX= YZ = 15.1cm

substitute the values,

\(tan ( Y Z X) = \frac{12.4}{15.1}\)

\(Angle ( Y Z X) = arc tan( \frac{12.4}{15.1} )\)

Angle ( Y Z X) = 39.4°

Answer:

the first one, 64(-1/2)^(n-1)

Step-by-step explanation:

To go from one number to the next, we first start with 64, so everything is multiplied by that. Next, 64 turns into -32, and (-32)/64 = -1/2. Similarly, 16/-32 is -1/2, and -8/16 is -1/2 as well. Therefore, we have to multiply each number by -1/2 a number of times. For example, to get from 64 to 16, we have to multiply 64 by negative one half 2 times. The only option with -1/2 in the multiplier is the first one, making that our answer
