The answer of the given question based on inequality is , inequality that represents an employee's income is x < 78000. and graph is

           <-----------|--------------o

           0      30,000     78,000

A number line is a visual representation of the real numbers, where numbers are placed in order on a straight line. It is a tool used in mathematics to help visualize and understand the relationship between numbers and their positions relative to each other.

A typical number line consists of a horizontal line with zero (0) placed in the center. Positive numbers are placed to the right of zero, and negative numbers are placed to the left of zero. The numbers are evenly spaced along the line and increase or decrease as we move further to the right or left.

The inequality that represents an employee's income being less than $78,000 per year is:

x < 78000

where x represents the employee's income.

To graph this inequality on a number line, we can draw a open circle at the point 78,000 and shade to the left of the circle to indicate all values less than 78,000. The graph would look like this:

           <-----------|--------------o

           0      30,000     78,000

The open circle at 78,000 indicates that the employee's income can be exactly $78,000, but the shading to the left of the circle indicates that the employee's income can also be any value less than $78,000.

Answer:

h > -11

Step-by-step explanation:

Given the inequality expression, -85 < 5h - 8 + 2h:

The goal is to isolate the variable in order to solve for h.

Start by adding 8 to both sides and combine like terms:

-85 + 8 < 5h - 8 + 8 + 2h

-77 < 7h

Divide both sides by 7 to isolate h:

\(\frac{-77}{7} < \frac{7h}{7}\)

-11 < h  or h > -11.

Answer:

h < -11

Step-by-step explanation:

-85 < 5h - 8 + 2h

First, we combine like terms:

-85 < 7h - 8

Next, we reorder the equation to make it easier for the next step.

7h - 8 < -85

Now, to isolate 7h, we transpose -8 to the other side of the less than sign.

Always remember that when we transpose something, wheter it's a number or variable, you must always switch it from negative to positive or positive to negative.

-8 is negative, so when it crosses the less-than sign, it turns into a +8.

So we do:

7h < -85 + 8

We combine like terms:

7h < -77

Now we simplify:

h < -11

Therefore, h < -11 in the equation -85 < 5h - 8 + 2h.

There are six possible ways a person can choose two balls at random from an urn containing five balls numbered 1, 2, 2, 6, and 6.

To understand how to calculate the number of combinations, let's break it down into two parts: selecting the first ball, and then selecting the second ball. Since there are five balls in the urn, the first ball can be chosen in five possible ways. Then, when selecting the second ball, the number of possible selections is reduced to four because one ball has already been selected. This can be expressed mathematically as: n(A)=5x4.

To calculate the total number of combinations, we then multiply the two numbers: 5x4=20. This result is then divided by two because the order of selection does not matter. As a result, 20/2=10, which means that there are ten possible combinations when choosing two balls at random from the urn. In conclusion, if an urn contains five balls numbered 1, 2, 2, 6, and 6, there are six possible ways a person can choose two balls at random. This can be expressed mathematically as n(A)=6 or n(A)=5x4/2.

The differential equation is given as dp/dt = 2√(Pt), with the initial condition P(1) = 3, the solution to the differential equation with the given initial condition is P(t) = (t + √3 - 1)^2.

Step 1: Separate the variables. Move all terms involving P to the left side and all terms involving t to the right side:
(dp/√P) = 2 dt
Step 2: Integrate both sides with respect to their respective variables:
∫(dp/√P) = ∫(2 dt)
Step 3: Evaluate the integrals:
2√P = 2t + C, where C is the constant of integration.
Step 4: Use the initial condition P(1) = 3 to find the value of C: 2√3 = 2(1) + C
C = 2√3 - 2
Step 5: Substitute the value of C back into the equation and solve for P(t): 2√P = 2t + 2√3 - 2
Step 6: Divide both sides by 2: √P = t + √3 - 1
Step 7: Square both sides to get P(t) alone:
P(t) = (t + √3 - 1)^2
So the solution to the differential equation with the given initial condition is P(t) = (t + √3 - 1)^2.

Answer:

The slope is -9/4 or -2.25.

Step-by-step explanation:

To find the slope (S) we need to use the following equation:

\( S = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \)

Where:

y₂: is the final height = 11 feet

y₁: is the initial heoght = 20 feet

x₂: is the final position is the horizontal direction = 4 feet

x₁: is the initial position = 0 (origin)

\( S = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{11 - 20}{4} = -\frac{9}{4} = -2.25 \)            

Therefore, the slope is -9/4 or -2.25.

Angle A is 19 degrees.

Angle C is 90 degrees.

Side a is approximately 7.83.

Side c is approximately 34.50.

To solve the right triangle given that B = 71 degrees and b = 24, we can use the trigonometric ratios sine, cosine, and tangent.

Finding Angle A:

Angle A is the complementary angle to B in a right triangle, so we can calculate it using the equation:

A = 90 - B

Substituting the given value, we have:

A = 90 - 71

A = 19 degrees

Therefore, Angle A is 19 degrees.

Finding Angle C:

Since it is a right triangle, Angle C is always 90 degrees.

Therefore, Angle C is 90 degrees.

Finding Side a:

We can use the sine ratio to find the length of side a:

sin(A) = a / b

Rearranging the equation to solve for a, we have:

a = b * sin(A)

Substituting the given values, we have:

a = 24 * sin(19)

a ≈ 7.83

Therefore, the length of side a is approximately 7.83.

Finding Side c:

Using the Pythagorean theorem, we can find the length of side c:

c^2 = a^2 + b^2

Substituting the given values, we have:

c^2 = 7.83^2 + 24^2

c^2 ≈ 613.68 + 576

c^2 ≈ 1189.68

Taking the square root of both sides to solve for c, we have:

c ≈ √1189.68

c ≈ 34.50

Therefore, the length of side c is approximately 34.50.

By solving a linear equation, we can see that the deep of the layer will be 6.37 ft.

For a cylinder of radius R and deep D, the volume is:

V = pi*R^2*D

Where pi = 3.14

In this case, we know that the diameter is 3 ft, so the radius is:

R = 3ft/2 = 1.5ft

And the volume of dirt used is 45 cubic feet, then the deep D must be a solution of the following linear equation:

45 ft^3 = 3.14*(1.5ft)^2*D

Solving this for D, we get:

(45 ft^3)/(3.14*(1.5ft)^2) = D

A plane intersects a cylinder perpendicular to its bases this cross section can be described as a rectangle. Therefore, the correct answer is option 1).

The cross section of a plane intersecting a cylinder perpendicular to its bases is a rectangle. This is because when a plane intersects a cylinder perpendicularly (at right angles) the cross-section area has the shape of a rectangle. The base of the rectangle is determined by the diameter of the cylinder and the height is determined by the length of the cylinder.

A parabola, triangle, and circle are not possible when the plane intersects the cylinder perpendicularly since their shapes cannot accurately represent the intersection of two geometric shapes.

From the question, y = \(\left[\begin{array}{ccc}4\\2\end{array}\right]\) and u = \(\left[\begin{array}{ccc}8\\6\end{array}\right]\).

Orthogonal projection is a type of projection used in linear algebra to determine the projection of a vector onto another vector. It is an important tool in mathematics and engineering, as it can be used to calculate the angle between two vectors, the distance between two points, and the projection of a vector onto a plane.

Orthogonal projection formula:

\(\hat{y}=\frac{y.u}{u.u}u\)

y · u = (4, 2) · (8, 6)

y · u = 32 + 12

y · u = 44

u · u = (8, 6) · (8, 6)

u · u = 64 + 36

u · u = 100

\(\hat{y}=\frac{y\cdot u}{u\cdot u}u\)

\(\hat{y}=\frac{44}{100}\begin{bmatrix} 8\\6 \end{bmatrix}\)

\(\hat{y}=\frac{11}{25}\begin{bmatrix} 8\\6 \end{bmatrix}\)

\(\hat{y}=\begin{bmatrix} 88/25\\66/25 \end{bmatrix}\)

From y, the line is at a distance of:

\(\left \| y-\hat{y} \right \|\)

\(y-\hat{y}=\begin{bmatrix} 4\\2 \end{bmatrix}-\begin{bmatrix} 88/25\\66/25 \end{bmatrix}\)

\(y-\hat{y}=\begin{bmatrix} 100/25\\50/25 \end{bmatrix}-\begin{bmatrix} 88/25\\66/25 \end{bmatrix}\)

\(y-\hat{y}=\begin{bmatrix} 12/25\\-16/25 \end{bmatrix}\)

\(\left \| y-\hat{y} \right \|=\sqrt{\left (\frac{12}{25} \right )^2+\left (\frac{-16}{25} \right )^2}\)

\(\left \| y-\hat{y} \right \|=\sqrt{\frac{144}{625}+\frac{256}{625}}\)

\(\left \| y-\hat{y} \right \|=\sqrt{\frac{400}{625}}\)

\(\left \| y-\hat{y} \right \|=\frac{20}{25}\)
