Student A has visited Website B: w(A,B).

This statement can be expressed in English as: "Student A has visited Website B." The formula for this statement is w(x, y), where x is the student, and y is the website. To calculate this statement, we would substitute A for x, and B for y, resulting in w(A, B). This tells us that Student A has visited Website B., we can use the formula w(x,y) = x * y, where x is the total number of students in the school and y is the total number of websites. For instance, if there are 100 students and 10 websites, then the total number of visits would be 100 * 10, or 1000 visits.

The statement "Student A has visited Website B" can be expressed in the formula w(x, y), where x is the student, and y is the website. To calculate this statement, we would substitute A for x, and B for y, resulting in w(A, B), which tells us that Student A has visited Website B.

Answer:

The work done by the constant unit force vector in moving the object 17 units in the positive x-axis direction is equal to the magnitude of the force multiplied by the displacement in the direction of the force. Since the force makes an angle of 30 degrees with the x-axis, the magnitude of the displacement in the direction of the force is equal to the displacement in the x-axis direction multiplied by the cosine of 30 degrees. Therefore, the work done is equal to the magnitude of the force multiplied by 17 multiplied by the cosine of 30 degrees. hope this helped

Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then select none.

When m8 = m4, the line segments are parallel.

When two line segments have the same slope (m8 = m4), then the line segments are parallel. Therefore, the statement that the line segments are parallel can be deduced if m8 and m4 are equal.

When two line segments have the same slope, then they will be parallel to each other. This can be deduced when the slopes of both line segments are equal, which is represented by m8 = m4. If the two line segments have the same slope, then they will be parallel to each other and will never meet or intersect. This is because parallel lines always have the same slope and never touch each other. In conclusion, the statement that two line segments are parallel can be deduced if m8 and m4 are equal.

The measure of angle ∠B is 44°.

What is the measure of all angles in a triangle?

A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.

We have given,  

Triangle ΔABC,

and angles ∠ACB = 90°, ∠CAB= 46°, and ∠ABC = ?

We know that the sum of all angles in the triangle is 180°.

So,

∠ACB + ∠CAB + ∠ABC = 180°

90° + 46° + ∠ABC = 180°,

136 + ∠ABC = 180°,

∠ABC = 180° - 136

∠ABC = 44°,

The required solution of the equations is given as (2, 3, 0).

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
So we are given a system,
3x -2y + 3z = 0
-3x-5y-5z = -21

Substitute x =2, and we get the system,
-2y + 3z = -6
-5y -5z = -15

Multiply equation 1 by -5 and equation 2 by 2 we get the system,
10y - 15z = 30
-10y -10z = -30

Adding the above equations,

The graph of the ordered pairs is plotted using the x- coordinates and the y-coordinates. As the straight line does not pass through all the points the relationship is not a linear function.

One variable is directly proportionate to the other in a linear connection, which is a sort of connection between two variables. To put it another way, one variable rises or falls linearly as the other one rises or falls, correspondingly. A line graph, in which the rate of progression is constant, is a frequent graphic depiction of a linear connection. Numerous branches of research, such as physics, psychology, and economics, utilize linear correlations.

The graph of the ordered pairs is plotted using the x- coordinates and the y-coordinates.

When the points are connected using a straight line, the line does not pass through the last point (4, 4). Thus, the ordered pairs do not represent a linear function. This can be determined using the graph, and the points through with the straight line passes.

Answer:

Step-by-step explanation 0% because there is more red markers

Answer: (Don't read this if this is a test)

Step-by-step explanation: I might get this wrong because I was kind of confused too (sorry if I am!)

Hello! The first thing you would want to do for these kinds of questions is to write the probability of a green, blue, or red marker being picked as a fraction.  To do this, add 12 + 4 + 20 which is 36.

The probability of picking a green marker - 12/36, partially simplified = 3/9

The probability of picking a blue marker - 4/36, simplified = 1/9

The probability of picking a red marker - 20/36, simplified = 5/9

G - 3/9
B = 1/9
R = 5/9

You know that the probability of picking a blue marker is 1/9.  Once you know this, you can figure out the new probability of picking a red marker since the blue marker won't be replaced.  The answer is 4/35.  Multiply 1/9 by 4/35 to find the probability of picking one after the other and you will get 4/315.

The initial number of people sick with the flu at time 0 is 100 and the rate of increase of the number of people sick with the flu is 120t - 3t^2 people per day.

P(t) = 100 + 120t - 3t^2

This formula can be used to calculate the number of people sick with the flu at time t, where time is measured in days from the beginning of the epidemic. The initial number of people sick with the flu at time 0 is 100 and the rate of increase of the number of people sick with the flu is 120t - 3t^2 people per day.

To calculate P(t), the initial number of people sick with the flu, 100, is added to the rate of increase of the number of people sick with the flu over t days, which is 120t - 3t^2. The sum of these two values is the number of people sick with the flu at time t.

For example, at t=2 days, P(2) = 100 + 120(2) - 3(2^2) = 100 + 240 - 12 = 328 people sick with the flu.

Answer:

Step-by-step explanation:

Vb=(4/3)r³π, Vc=r²πh, h is the height of the cylindrical container.

h=12r.

So now the volume of the cylinder is:

Vc=r²π*12r=12r³π.

There are 6 balls so their total volume is:

6*Vb=6*(4/3)*r³*π=(24/3)*r³π=8r³π.

Now we subtract the volume of 6 balls from the volume of the cylinder to get the volume of air Va inside the cylinder:

Va=Vc-6*Vb=12r³π-8r³π=4r³π.

Model the squash ball as a sphere.

Assuming the six squash balls are packaged in a cylindrical container where each ball is one on top of the other, the height of the container is 6 times the height of a squash ball.  

The height of a squash ball is its diameter, which is twice its radius.  

Therefore, the height of the cylinder is 12 times the radius of the squash ball, and the radius of the cylinder is the radius of the squash ball.

Therefore:

The range of the function y = -2x² + 12x - 13 will be [5, -∞). Then the correct option is A.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The domain means all the possible values of x and the range means all the possible values of y.

The equation is given below.

y = -2x² + 12x - 13

Convert the equation into a vertex form, then we have

y = -2x² + 12x - 13

y = -2x² + 12x - 18 + 18 - 13

y = -2(x² - 6x + 9) + 18 - 13

Answer:

4x + 7y = 27

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b

Here m = slope which is the rate of change of the y-value with respect to x and b is the y-intercept which is the y-value where the line crosses the x-axis. It is therefore the value of y when x = 0

We are given slope = -4/7

So equation of line is
y = (-4/7)x + b

To find b, notice that the given point is (5, 1) which indicates that at this point x = 5, y = 1

If we plug in x = 5 in the equation we should get a y0value of 1

We can rewrite y = (-4/7)x + b as

(-4/7)x + b  = y  

Substitute x=5 and y = 1

(-4/7)(5) + b = 1

-20/7  + b = 1

b = 1 + 20/7

b = 27/7

So the equation of the line in slope intercept form is

[tex]\quad y=-\dfrac{4}{7}x+\dfrac{27}{7} \cdots (1)[/tex]

The standard form of a line equation is
Ax + By = C

We can convert equation (1) to standard form by tweaking it
