Find the remaining trigonometric functions of if csc = 29/ 21 and cos < 0

Answer:

The first table(top row, leftmost) represents a function

Step-by-step explanation:

In a function y = f(x), the value for y must be unique for a value of x

In other words, you cannot have two different values of y for the same x

We see that only the first table(top row, leftmost) satisfies this requirement

So that is the answer

Second table has two values for x = -5

Third table has two values of x = -2

Fourth table has two  values for x = -4

The equation 3y + 7 = x does not represent a direct proportion.

The constant of proportionality is a value that describes the relationship between two variables in a proportional relationship. For example, if y is proportional to x, and y = 2 when x = 4, then the constant of proportionality would be 0.5 (since 2/4 = 0.5). The constant of proportionality is often represented by the letter "k".

A direct proportion is a relationship between two variables where their ratio is always constant.

In the equation, 3y + 7 = x, the relationship between x and y is not fixed, so it does not represent a direct proportion.

The total amount due on November 15th would be $1667.81

Let's first calculate the trade discount amount:

Suggested list price: $1400

Trade discount rate: 40/10 = 4%

Trade discount amount: $1400 x 4% = $56

After deducting the trade discount, the price becomes:

$1400 - $56 = $1344

Next, let's calculate the cash discount:

Amount after trade discount: $1344

Cash discount rate: 8/10 = 8%

Cash discount amount: $1344 x 8% = $107.52

After deducting the cash discount, the price becomes:

$1344 - $107.52 = $1236.48

Finally, let's calculate the total amount due:

Amount after cash discount: $1236.48

Markup rate: 35%

Markup amount: $1236.48 x 35% = $431.33

Total amount due: $1236.48 + $431.33 = $1667.81

So, the total amount due on November 15th would be $1667.81.

Answer:

This question is asking for a construction problem, which involves using a pair of compasses and a ruler to draw the triangle DEF and then measure certain aspects of the triangle, such as the length of DF, the height of XF, and the locus of a point 2cm from E. It also requires bisecting the angle D.

Step-by-step explanation:

a. To construct the triangle DEF, use the compasses to draw arcs with radii of 3cm and 7cm from points D and E respectively, so that the arcs intersect. Then, connect the points of intersection with a straight line to form the side DE. Next, use the compasses to draw an arc with a radius of 8cm from point F and intersect it with the previous arcs. Connect the points of intersection with a straight line to form the side DF. Finally, use the ruler to connect the points D, E, and F to form the triangle. To draw the perpendicular line at X, draw a line segment parallel to DE passing through the midpoint X, and then use the compasses to draw arcs centered at X and intersecting the sides DE and DF. Connect the points of intersection to form the perpendicular line at X.

b. Measure the length of DF using a ruler.

c. Measure the height of the triangle XF by measuring the distance from X to DF.

d. The locus of the point that is 2cm from E can be found by drawing an arc with a radius of 2cm centered at E and intersecting the sides DE and DF. The points of intersection represent the points that are 2cm from E.

e. To bisect the angle D, use the compasses to draw two arcs centered at D that intersect the sides DE and DF. Connect the points of intersection to form the bisector of angle D.

It is important to note that these steps are only a general guide and may need to be adjusted slightly depending on the specifics of the problem.

Answer:

The function displayed in the table is best described as an Exponential Decay Function.

Step-by-step explanation:

            First, the main difference between a linear and an exponential function is the shape of its graph, as well as the presence of either a constant ratio or a constant rate of change.

            Linear functions are functions with a base function of  [tex]f(x)=mx+b[/tex], which has a constant rate of change ([tex]m[/tex]), and the shape of its graph will be a straight line.

            Exponential functions on the other hand use the base function [tex]f(x)=a^x[/tex], where [tex]a[/tex] is the constant ratio of the function, and its graph is curved and has a horizontal asymptote that the graph will approach but never touch as it either increases or decreases to positive or negative infinity respectively.

            The function in the problem gives you four points that are on its graph: (-2, 540), (-1, 270), (0, 135), and (1, 67.5). Using these points, you can determine whether it is a linear or exponential function. You can tell that when the x-value increases by 1, the f(x) value is divided by 2, or multiplied by [tex]\frac{1}{2}[/tex]. Since there is a constant ratio instead of a constant rate of change in the function, you would know that the function in the table is an exponential function. Since the function is also constantly decreasing, the function would be best described as an Exponential Decay Function.

Sum of coordinates, S + T = (9 , -7)

A coordinate is an address, which helps to locate a point in space. For a two-dimensional space, the coordinates of a point are (x, y). Here let us take note of these two important terms.

Abscissa: It is the x value in the point (x, y), and is the distance of this point along the x-axis, from the origin

Ordinate:  It is the y value in the point (x, y)., and is the perpendicular distance of the point from the x-axis, which is parallel to the y-axis.

Given,

S = (4 , -6)

T = (5 , -1)

S + T = (4 , -6) + (5 , -1)

        = (4 + 5 , -6 + -1)

        = (9 , -7)

Hence, S + T = (9 , -7) is sum of coordinates of point S and T

The cumulative relative frequency graph shows that

The slope between 0 and 4 is substantially steeper than the curve between 6 and 14.

Then

Because most of the data values are between 0 and 4 (where the histogram's highest bar appears) and relatively few values lie between 6  and 14 the histogram's distribution should be skewed to the right, resulting in low bars tailing to the right side of the highest bars.

So the slope of the scenario is $28 per hour, which indicates that the expense of the tour increases by $28 for every extra hour spent on it.

The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x). The slope-intercept form of an equation occurs when the equation of a line is stated in the form y = mx + b. The slope of the line is given by m. And b is the value of b in the y-intercept point (0, b). For example, the slope of the equation y = 3x - 7 is 3, while the y-intercept is (0, 7).

Here,

In this situation, the slope represents the rate of change in the cost of the tour with respect to the time spent on the tour. The slope of the situation can be calculated as the change in cost divided by the change in time.

Since the one-time fee is a fixed cost, it does not change with respect to the time spent on the tour. Therefore, the slope can be calculated as the rate of change in the cost due to the hourly fee of $28.

The slope can be represented as:

slope = Δcost/Δtime = $28/hour

So, the slope of the situation is $28 per hour, which means that for every additional hour spent on the tour, the cost of the tour increases by $28.

Step-by-step explanation:

No, the number of students at Lake View Middle School is not proportional to the number of teachers.

Proportionality between two quantities means that they maintain a constant ratio, regardless of their actual values. In this case, if the number of students and teachers were proportional, we would expect the ratio of students to teachers to remain constant as the total number of students or teachers changes.

However, in this scenario, the ratio of students to teachers is not constant. The ratio is 48:2, which simplifies to 24:1. This means that there are 24 students for every 1 teacher. If the number of students at the school were to double to 96, we would expect the number of teachers to double as well if they were proportional. However, this would mean that there would be 4 teachers assigned to the students, which is twice the original number of teachers assigned to the original number of students.

Therefore, the number of students at Lake View Middle School is not proportional to the number of teachers, because the ratio of students to teachers is not constant, and it changes as the total number of students or teachers changes.

2) f(x) = 4x² + 24x - 7 → Vertex form is y = 4(x + 3)² - 43 and vertex is (-3,-43).

3) f(x) = -2x² - 8x + 9 → Vertex form is y = -2(x + 2)² + 17 and vertex is (-2,17).

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The quadratic equation is written in the form ax² + bx + c = 0.

The vertex form of a quadratic equation is -

y = a(x - h)² + k

The first equation is - f(x) = x² - 16x + 3.

Here, a = 1, b = -16 and c = 3

The formula for h is -

h = -b/2a

h = -(-16)/2(1)

h = 16/2

h = 8

The formula for k is -

k = c - (b²/4a)

k = 3 - [(-16)²/4(1)]

k = 3 - (256/4)

k = 3 - 64

k = -61

So, the vertex form is -

y = a(x - h)² + k

y = 3(x - 8)² - 61

The vertex is written as (h,k).

The vertex is (8,-61).

Therefore, the vertex form and vertex is y = 3(x - 8)² - 61 and (8,-61) respectively.

The second equation is - f(x) = 4x² + 24x - 7.

Here, a = 4, b = 24 and c = -7

The formula for h is -

h = -b/2a

h = -(24)/2(4)

h = -24/8

h = -3

The formula for k is -

k = c - (b²/4a)

k = -7 - [(24)²/4(4)]

k = -7 - (576/16)

k = -7 - 36

k = -43

So, the vertex form is -

y = a(x - h)² + k

y = 4(x + 3)² - 43

The vertex is written as (h,k).

The vertex is (-3,-43).

Therefore, the vertex form and vertex is y = 4(x + 3)² - 43 and (-3,-43) respectively.

The third equation is - f(x) = -2x² - 8x + 9.

Here, a = -2, b = -8 and c = 9

The formula for h is -

h = -b/2a

h = -(-8)/2(-2)

h = 8/-4

h = -2

The formula for k is -

k = c - (b²/4a)

k = 9 - [(-8)²/4(-2)]

k = 9 - (64/-8)

k = 9 + 8

k = 17

So, the vertex form is -

y = a(x - h)² + k

y = -2(x + 2)² + 17

The vertex is written as (h,k).

The vertex is (-2,17).

Therefore, the vertex form and vertex is y = -2(x + 2)² + 17 and (-2,17) respectively.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations. The intersection of two lines represents the system of equations' solution.

Given system of equations are,

6x + 11y = -3

4x + y = 17

To solve these equations, we must first remove x or y terms.
