What is the tan of 30 degrees
Answer:
The value of tan 30 degrees is 0.57736.
Step-by-step explanation:
Tan 30 degrees in radical form is = [tex]\frac{1}{\sqrt{3} }[/tex]
We know [tex]\sqrt{3}[/tex] = 1.732
So, tan 30 degrees = [tex]\frac{1}{1.732}[/tex]
= 0.57736
The answer is 0.57736.
Please find attached the exact value reference triangle .
The required value of tan 30 degrees is 1/[tex]\sqrt{3}[/tex].
Given the trigonometric function tan 30 degrees.
The tangent of 30 degrees, written as tan(30°), can be evaluated without a calculator by using the trigonometric properties of special angles.
In a right triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
For a 30°- 60°- 90° right triangle, the side opposite the 30-degree angle is half the length of the hypotenuse, and the side adjacent to the 30-degree angle is equal to the length of the hypotenuse multiplied by
[tex]\sqrt{3}[/tex]/2.
In a 30°-60°-90° triangle, the tangent of 30 degrees is given by:
tan(30°) = (opposite side) / (adjacent side)
tan(30°) = (1/2) / ([tex]\sqrt{3}[/tex]/2)
tan(30°) = 1/[tex]\sqrt{3}[/tex] = [tex]\sqrt{3}[/tex]/3.
tan (30°) = [tex]\sqrt{3}[/tex]/3
Multiply both numerator and denominator by [tex]\sqrt{3}[/tex] gives,
tan(30°) = 3/3[tex]\sqrt{3}[/tex].
Divide both numerator and denominator by 3 gives,
tan(30°) = 1/[tex]\sqrt{3}[/tex].
Therefore, the tangent of 30 degrees is 1/[tex]\sqrt{3}[/tex].
Hence, the required value of tan 30 degrees is 1/[tex]\sqrt{3}[/tex].

Find the marginal cost, marginal revenue, and marginal profit functions. Find all values of x for which the marginal profit is zero.
C(x) = 5x
R(x) = 8x − 0.001x^2
The marginal cost function is MC(x) = 5, the marginal revenue function is MR(x) = 8 - 0.002x, and the marginal profit function is MP(x) = MR(x) - MC(x). The quantity at which the marginal profit is zero is x = 1500.
Explanation:The marginal cost (MC) function represents the change in total cost when one additional unit is produced. It can be calculated by taking the derivative of the total cost function with respect to quantity (x). In this case, the total cost function is given as C(x) = 5x, so the marginal cost function is MC(x) = 5.
The marginal revenue (MR) function represents the change in total revenue when one additional unit is sold. It can be calculated by taking the derivative of the total revenue function (R(x)). In this case, the total revenue function is R(x) = 8x − 0.001x^2, so the marginal revenue function is MR(x) = 8 - 0.002x.
The marginal profit (MP) function represents the change in profit when one additional unit is produced and sold. It can be calculated by subtracting the marginal cost from the marginal revenue: MP(x) = MR(x) - MC(x).
To find all values of x for which the marginal profit is zero, set the marginal profit function equal to zero and solve for x: 0 = MR(x) - MC(x). In this case, 0 = (8 - 0.002x) - 5. Solving for x gives x = 1500, which is the quantity at which the marginal profit is zero.

A cell phone company offers you a plan that charges a flat rate of $25 per month for 200 minutes of airtime. The rate of any time in excess of 200 minutes is $.12 per minute.
A. Write an expression for the monthly dollar amount spent for the cell phone service if you want to use x minutes of airtime in excess of 200 minutes.
B. Write an equation which indicates that you have budgeted no more than $40 per month to spend on the service.
C. Determine the maximum number of minutes you can use in excess of 200 minutes so that you do not exceed your $40 per month budget.
The expression for the monthly dollar amount spent is $25 + 0.12x. The equation for budgeting no more than $40 is $25 + 0.12x ≤ $40. The maximum number of minutes under the $40 budget is 125 minutes.
Explanation:A. The expression for the monthly dollar amount spent for the cell phone service if you want to use x minutes of airtime in excess of 200 minutes is: $25 + 0.12x. This accounts for the flat rate of $25 plus the additional charge of $0.12 per minute over 200 minutes.
B. The equation which indicates that you have budgeted no more than $40 per month to spend on the service is: $25 + 0.12x ≤ $40. This equation represents the total monthly cost being less than or equal to $40.
C. To determine the maximum number of minutes you can use in excess of 200 minutes so that you do not exceed your $40 per month budget, we solve the equation from B. Start by subtracting $25 from both sides to isolate the variable: 0.12x ≤ $40 - $25. Simplifying gives us: 0.12x ≤ $15. Then, divide both sides by 0.12 to solve for x: x ≤ $15/0.12. Simplifying further gives us: x ≤ 125. Therefore, the maximum number of minutes you can use in excess of 200 minutes is 125 minutes.

Answer:
-The rays extend infinitely and the angle is made by the rays which have a common endpoint.

A ray starts from one point and extends in one direction forever.
An angle is the space between two intersecting lines at or close to the point where they meet. In this case two rays intersect each other at one point

A.
∠3 and ∠5
B.
∠2 and ∠8
C.
∠2 and ∠7
D.
∠1 and ∠8
i think B
The pair of alternate exterior angles is ∠2 and ∠8 in the context of two parallel lines intersected by a transversal.
The correct answer is option B.
When two parallel lines are intersected by a transversal, alternate exterior angles are pairs of angles that are on opposite sides of the transversal and outside the set of parallel lines. In the given options:
A. ∠3 and ∠5: These angles are on the same side of the transversal, not alternate exterior angles.
B. ∠2 and ∠8: These angles are on opposite sides of the transversal and outside the parallel lines, making them alternate exterior angles.
C. ∠2 and ∠7: These angles are on the same side of the transversal, not alternate exterior angles.
D. ∠1 and ∠8: These angles are on the same side of the transversal, not alternate exterior angles.
Therefore, the correct pair of alternate exterior angles is option B: ∠2 and ∠8.

Without Graphing, Is The System Independent, Dependent, Or Inconsistent? (Equation And Answer Choices Are In Comments!)
In statistics, the independent variable is plotted on the x-axis and the dependent variable on the y-axis of a scatter plot, which is used to analyze the relationship between variables. The correlation coefficient determines the strength and direction of this relationship, while the line of best fit predicts values of the dependent variable.
Explanation:In statistics, when analyzing a set of data that consists of two variables, we typically designate one variable as the independent variable and the other as the dependent variable. The independent variable is the one that is presumed to cause or explain changes in the other variable, which is the dependent variable. When these variables are plotted on a graph, the independent variable is placed on the x-axis (horizontal axis), and the dependent variable is placed on the y-axis (vertical axis).
To explore the relationship between two variables, creating a scatter plot is a common first step. This graph will show individual data points representing the pairs of values for the two variables. By inspecting the scatter plot, one might observe whether there is a clear pattern or trend that suggests a relationship. If the points tend to fall along a line, it indicates that there is a linear relationship between the variables.
The next step would be to calculate the line of best fit, also known as the least-squares line, using regression analysis. The equation of this line is typically in the form ŷ = a + bx, where 'a' is the y-intercept and 'b' is the slope. The line of best fit represents the linear relationship between the variables and is used to predict the value of the dependent variable, given a value of the independent variable.
Another important step is to determine the correlation coefficient, often denoted as 'r'. This coefficient measures the strength and direction of the linear relationship between the two variables. A correlation coefficient close to +1 or -1 indicates a strong correlation, while one close to 0 indicates little to no correlation.
