The graph representing the solution of the inequalities y < 3/4x + 3 and y ≤ -2x - 1 is option B.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The first inequality is given as y < 3/4x + 3.

The second inequality is given as y ≤ -2x - 1.

To find the intersection point for the system of inequalities without graphing, we need to solve the two inequalities simultaneously by finding the values of x and y that satisfy both of them.

We can start by setting the two inequalities equal to each other -

y = 3/4x + 3 (from the first inequality)

y = -2x - 1 (from the second inequality)

Since both equations are equal to y, we can set them equal to each other -

3/4x + 3 = -2x - 1

We can simplify and solve for x -

3/4x + 2x = -1 - 3

11/4x = -4

x = -16/11

To find the value of y that corresponds to this value of x, we can substitute it into either equation.

Using the second equation, we have -

y = -2(-16/11) - 1

y = 29/11

So, the intersection point for the system of inequalities is (-16/11, 29/11).

The graph for inequality y ≤ -2x - 1 will be a straight line denoting (≤,≥) symbol.

The graph for inequality y < 3/4x + 3 will be a dotted line denoting (<,>) symbol.

Therefore, the graph that shows this intersection point and satisfies the condition is graph of option B.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It has many real-world applications such as in (engineering, architecture, and navigation.)

15. One application of trigonometry is in determining the height of a building. This can be done by measuring the angle of elevation from a known distance away from the building and using trigonometric functions to find the height.
16. Another application of trigonometry is in surveying land. Surveyors use trigonometry to measure distances and angles between different points on a piece of land, which helps them create accurate maps and boundary lines.
17. Trigonometry is also used in physics to calculate the motion of objects that move in a circular or oscillatory motion, such as a pendulum or a rotating wheel.
18. Finally, trigonometry is used in astronomy to calculate the position and movement of celestial bodies. Astronomers use trigonometric functions to measure the distance between stars and galaxies

Step-by-step explanation:

The linear equation that models the cost as a function of the number of hours is:

y = 40*x + 20

We know that a repair that takes two hours costs $100 and a repair that takes 6 hours costs $260.

Let's assume this is a linear equation, then:

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

slope = (y2 - y1)/(x2 - x1)

Here we have the two points (2, 100) and (6, 260), then the slope is:

a = (260 - 100)/(6 - 2) = 160/4 = 40

So our line is something like:

y = 40*x +b

To find the value of b we use the fact that our line passes trhough (2, 100), then:

100 = 40*2 + b

100 - 80 = b

20  = b

Then the linear equation is:

y = 40*x + b

Answer:

constant is - 19

Step-by-step explanation:

the constant is the term in an expression with no variable attached to it.

12r + \(\frac{r}{2}\) - 19

the only term without the variable r attached to it is - 19

then the constant term is - 19

The total weight of the liquid in the tank is approximately 12,628 pounds.

To calculate the weight of the liquid, we need to determine the volume of the hemisphere and then multiply it by the density of the liquid. The formula for the volume of a hemisphere is V = (2/3)πr³, where r is the radius of the hemisphere.

In this case, the diameter of the tank is given as 24 feet, so the radius is half of that, which is 12 feet. Plugging this value into the formula, we get V = (2/3)π(12)³ ≈ 904.78 cubic feet.

Finally, we multiply the volume by the density of the liquid: 904.78 cubic feet * 92.5 pounds per cubic foot ≈ 12,628 pounds. Therefore, the total weight of the liquid in the tank is approximately 12,628 pounds.

In summary, to calculate the weight of the liquid in the tank, we first determine the volume of the hemisphere using the formula V = (2/3)πr³. Then, we multiply the volume by the density of the liquid.

By substituting the given diameter of 24 feet and using the appropriate conversions, we find that the total weight of the liquid is approximately 12,628 pounds.

The new coordinates of the reflected point will be (2, 2).

In mathematics, reflection is a transformation that "flips" an object over a line or plane. Reflection is a type of symmetry, where an object appears exactly the same after being reflected as it did before.  

When a point is reflected across the y-axis, its x-coordinate changes sign while its y-coordinate remains the same.  

Here we have

The point (-2, 2) is reflected across the y-axis

When a point is reflected across the y-axis, its x-coordinate changes sign while its y-coordinate remains the same.

The new coordinate of the point = (-(-2), 2) = (2, 2)

Therefore,

The new coordinates of the reflected point will be (2, 2).

decimal form = 0.291667.

The value of the expression 5z - 3z, when z is equal to 3, is 6.

Given the expression in the question:

Evaluating an expression simply means substituting the given value of a variable into the expression and simplifying the result.

Given the expression 5z - 3z, we are given the value of z as 3.

Hence, we substitute z with 3 in the expression:

5z - 3z

Plug in z = 3

5(3) - 3(3)

Simplifying further using the order of operations (multiplication before subtraction), we get:

15 - 9

= 6

Therefore, the value of the expression is 6.

Just so that we have something to work with, the length of the longest day (June 22) in Acron Ohio is 15 hours 8 minutes and 9 seconds on the 20th of June of this year. The number we get won't be this accurate, but it will tell us if we have done it correctly. The tricky part is when to use the radians.

cos(0.1309 H) = -0.4336 tan (40o 46 minutes)  I have assumed this is in radians. It won't work any other way. The measurement cannot be in degrees which will give a negative tan from the minus sign out in front. The cos being minus will make things even worse.

cos(0.1309 H) = -0.4336 tan (40 46/60  )

cos(0.1309 H) = -0.4336 tan (40.766666667)

cos(0.1309 H) = -0.4336 * -0.074173405

cos(0.1309 H) = 0.032161588

0.1309 H = cos-1(0.032161588)

0.1309 H =  1.538629191

H = 1.538629191 / 0.1309

H = 11.754 which is no where near 15 hours, but it is what the numbers give.

The electric current to flow through the resistors and complete the circuit by reaching its intended destination or powering a device.

In the analogy of a circuit with resistance, we can compare it to an obstacle race. Here's how we can relate the different elements:

Circuit: The entire obstacle race course represents the circuit itself. It includes all the components and paths that the participants will go through.

Obstacles: The obstacles in the race represent the resistors in the circuit. Just like resistors impede the flow of electrical current in a circuit, obstacles in the race impede the progress of the participants.

People/Participants: The people participating in the race represent the flow of electric current in the circuit. They are the "charge" moving through the circuit, encountering and overcoming obstacles (resistors) to reach the finish line.

The goal of the participants (people) is to navigate through the obstacles (resistors) and complete the race (circuit) by reaching the finish line.

Similarly, in an electrical circuit, the goal is for the electric current to flow through the resistors and complete the circuit by reaching its intended destination or powering a device.
