What is the system of equations?
A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.
Let's start by defining some variables:
Let b be the price of a balcony ticket
Let f be the price of a general admission floor ticket
We can set up a system of two equations based on the information given in the problem:
77b + 69f = 5,883 (equation 1 for Friday's show)
75b + 69f = 5,775 (equation 2 for Saturday's show)
We can use either substitution or elimination to solve for b and f. Let's use elimination by subtracting equation 2 from equation 1:
(77b + 69f) - (75b + 69f) = 5,883 - 5,775
2b = 108
b = 54
Now that we know the price of a balcony ticket is $54, we can substitute this value into either equation to solve for f. Let's use equation 1:
77(54) + 69f = 5,883
4,158 + 69f = 5,883
69f = 1,725
f = 25
Therefore, the price of a general admission floor ticket is $25.

A parabola opening up or down has vertex (0, 1) and passes through (8, 17). Write its
equation in vertex form.
Answer: y = (1/4)x^2 + 1
Step-by-step explanation:
The equation of a parabola in vertex form is given by:
y = a(x-h)^2 + k
Where (h,k) is the vertex of the parabola and "a" is a coefficient that determines the shape of the parabola.
In this case, the vertex is given as (0,1), so h=0 and k=1. Also, the parabola passes through the point (8,17), which means that when x=8, y=17. We can use this information to solve for "a".
Substituting the values of h, k, x, and y in the equation, we get:
17 = a(8-0)^2 + 1
Simplifying this equation, we get:
17 - 1 = 64a
16 = 64a
a = 16/64
a = 1/4
Now that we know the value of "a", we can substitute it in the vertex form equation to get the final equation of the parabola:
y = (1/4)(x-0)^2 + 1
Simplifying this equation, we get:
y = (1/4)x^2 + 1
Therefore, the equation of the parabola in vertex form is y = (1/4)x^2 + 1.
Explanation:
We start with the general equation of a parabola in vertex form and substitute the given values of the vertex and the point that the parabola passes through. Then, we solve for the coefficient "a" by simplifying the resulting equation. Once we have the value of "a", we substitute it in the vertex form equation to obtain the final equation of the parabola.

Therefore, the cost price is $1113.64 if the selling price is $980 and the loss is 12%.
What is cost price?Cost price (also known as CP) is the amount of money that is required to produce or purchase a particular product or service. It includes all the expenses incurred in the production or purchase of a product, such as the cost of raw materials, labor, transportation, rent, and other overhead expenses. The cost price is an important factor in determining the profit margin of a business, as it is used to calculate the selling price of a product or service. In general, the cost price is the amount that a seller pays to acquire a product, while the selling price is the amount that a buyer pays to purchase the same product.
Let's assume that the cost price is "C".
We know that the selling price (S) is $980, and the loss percentage is 12%.
We can use the formula for calculating the cost price:
C = S / (1 - Loss%)
where Loss% is expressed as a decimal (i.e., 12% = 0.12).
Substituting the values, we have:
C = $980 / (1 - 0.12)
C = $980 / 0.88
C = $1113.64

Zendaya randomly selected marbles from a bag during a probability experiment. She completed 50 rounds and recorded the results in the table shown. Based on the information from her experiment, in how many of the next 200 rounds would she pick a blue marble?
We can expect her to pick about 70 blue marbles in the next 200 rounds.
How many of the next 200 rounds would she pick a blue marble?We must divide the number of blue marbles by the total number of marbles to determine the likelihood of selecting a blue marble in a single round:
P(blue) = 14/40 = 7/20
Since the experiment has been conducted 50 times, we may anticipate that the proportion of blue marbles will eventually be around 7/20. This suggests that in the subsequent 200 rounds, Zendaya will likely choose to focus on:
70 blue marbles result from P(blue) 200 = (7/20) 200.
So, in the following 200 rounds, we can anticipate her choosing roughly 70 blue marbles.

The vertex of a parabola is (0, 0) and the focus is(1/8,0).What is the equation of the parabola?
The equation of the parabola is
[tex]y = \frac{1}{32} {x}^{2} [/tex]
What is the vertex form of the equation of a parabola?
[tex]y = a {(x - h)}^{2} + k[/tex]
where (h, k) is the vertex and 'a' is a constant that determines the shape of the parabola. For a parabola with a horizontal axis of symmetry (opening to the right or left), the focus is (h + c, k), where c is the distance from the vertex to the focus, and the directrix is the line x = h - c.
Given,the vertex of a parabola is (0, 0) and the focus is(1/8,0).
We want to find equation of the parabola.
Given by In this problem, the vertex is at (0,0) which means h=0 and k=0. Also, the focus is at (1/8,0) which means c=1/8. So, the directrix is the line x = -1/8.
Since the parabola opens to the right, the equation of the parabola can be written as:[tex]y = {(x - 0)}^{2} + 0[/tex]
or simply: [tex]y = a {x}^{2} [/tex]
To find the value of 'a', we need to use the distances formula between the vertex and the focus:
[tex]c = \frac{1}{8} = \sqrt{ \frac{4a}{2} } \\ a = \frac{1}{32} [/tex]

If Gretchen randomly chooses one of the boxed lunches, what is the probability that she will get a roast beef sandwich on wheat bread and popcorn in her box?
To calculate the probability of Gretchen getting a roast beef sandwich on wheat bread and popcorn in her boxed lunch, we need to know the total number of possible boxed lunch combinations and the number of boxed lunches that contain roast beef on wheat bread and popcorn.
Let's assume there are 4 different types of sandwiches available: roast beef on wheat bread, turkey on white bread, ham on rye bread, and vegetarian on whole wheat bread. Also, let's assume there are 3 different snack options available: popcorn, chips, and fruit.
If each boxed lunch contains one sandwich and one snack, then there are 4 x 3 = 12 possible boxed lunch combinations.
Out of these 12 combinations, we need to determine how many contain roast beef on wheat bread and popcorn. Let's say there are 2 boxed lunches that contain roast beef on wheat bread and popcorn.
Therefore, the probability of Gretchen randomly choosing a boxed lunch with roast beef on wheat bread and popcorn is 2/12, which simplifies to 1/6, or approximately 0.1667.
So, there is a 16.67% chance that Gretchen will get a roast beef sandwich on wheat bread and popcorn in her box.

Find the measure of X
Answer:
X=18.88
Step-by-step explanation:
This is a 90 degree triangle which means that you can use Sin, Cos, Or Tan. In this case you have to use Tan as you don't know the hypotenuse length. Which means you would set up an equation that looks like Tan(42°)=17/x as tangent is opposite over adjacent. Then if you were to solve for X eventually you'll get X= 17/Tan(42°) and if you plug it in a calculator you would get that X= 18.88 or 19 if you round to a whole number.
a jar contains 30 coins, all dimes and quarters. the value of the coins is $4.80. how many of each coin is in the jar
Answer:
Step-by-step explanation:
1 quarter = 25 cents
1 dime = 10 cents
Let
q = the number of quarters, q>=0, q is integer
d = the number of dimes, d>=0, d is integ
30 coins totaling $4.80 = 480 cents:
q + d = 30
25q + 10d = 480
q = 12 quarters
d = 18 dimes
12 quarters and 18 dimes.
Answer:
Let x be the number of dimes in the jar.
Then the number of quarters in the jar would be 30 - x.
The total value of the dimes in the jar would be 0.10x, and the total value of the quarters would be 0.25(30 - x) = 7.50 - 0.25x.
We know that the total value of the coins is $4.80, so we can set up the equation:
0.10x + 7.50 - 0.25x = 4.80
Simplifying and solving for x, we get:
0.15x = 2.70
x = 18
Therefore, there are 18 dimes and 30 - 18 = 12 quarters in the jar.

A rectangular park measuring 200m by 100m has a 2m flower border constructed around the two longer sides and one shorter side. Also a circular fish pond of diameter 20m is in the center of the park and the remainder of the park is grassland. Calculate the following areas correct to the nearest square meters. a) the fish pond. b) the flower borders. c) the grassland. d) the perimeter of the park.
Step-by-step explanation:
a) The area of the fish pond is given by the formula:
Area = πr^2
where r is the radius of the pond (which is half of the diameter). So, in this case, r = 10m.
Area = π(10m)^2
Area = 100π m^2
Area ≈ 314 m^2 (rounded to the nearest square meter)
b) The flower border has a width of 2m on the two longer sides and one shorter side of the rectangular park. So, we need to find the area of three strips of land, each of which is 2m wide and has a different length.
The length of the two longer sides is 200m, so the total length of the two strips along these sides is:
2 × 200m = 400m
The length of the shorter side is 100m, but we need to subtract the width of the fish pond (which is 20m) from it, since the flower border does not extend around the pond. So, the length of the strip along this side is:
100m - 20m = 80m
Therefore, the total area of the flower border is:
2m × 400m + 2m × 80m = 960m^2
c) The grassland is the remaining area of the rectangular park after we subtract the area of the fish pond and the flower border from the total area of the park.
The total area of the park is:
200m × 100m = 20,000m^2
The area of the fish pond is:
π(10m)^2 ≈ 314m^2
The area of the flower border is:
960m^2
So, the area of the grassland is:
20,000m^2 - 314m^2 - 960m^2 = 18,726m^2
d) The perimeter of the park is the sum of the lengths of all its sides.
The two longer sides have a length of 200m each, but we need to add the lengths of the two flower borders (each of which is 2m wide), so the total length of the two longer sides is:
200m + 2m + 2m = 204m
The shorter side has a length of 100m, but we need to add the length of the flower border (which is 2m wide), so the total length of the shorter side is:
100m + 2m = 102m
The perimeter of the park is:
204m + 204m + 102m = 510m
Therefore, the perimeter of the park is 510 meters.
what signs are sin(100°) and tan(100°)?
A)sin(100°) >0 and tan (100°) < 0
B) they both positive
c) sin(100°) < 0 and tan (100°) > 0
d) they both negative
Answer:
A)sin(100°) >0 and tan (100°) < 0
Step-by-step explanation:
You want to know the signs of sin(100°) and tan(100°).
Quadrant100° is an angle in the 2nd quadrant, where angles between 90° and 180° lie.
In that quadrant, the sine function is positive, and the cosine function is negative. The tangent is the ratio of sine to cosine, so the tangent is negative in the 2nd quadrant.
sin(100°) > 0tan(100°) < 0__
Additional comment
Of course, your calculator can help you figure this out. Be sure it is in degrees mode.
The second attachment shows you sine is positive above the x-axis; cosine is positive to the right of the y-axis. Everything else derives from this.

The point (2, 2) would end up at the point (1, 1) after the transformations.
Describe Function?Functions can be represented in different ways, including graphs, tables, and equations. A graph of a function is a visual representation of the relation between the inputs and outputs, usually plotted on a coordinate plane. A table of values lists the inputs and corresponding outputs of a function. An equation of a function expresses the rule for calculating the output in terms of the input variable.
To sketch the graph of the new function h(x), we can start by considering the effect of each transformation on the original function f(x).
First, we have a horizontal shift of 1 unit to the left, since we are subtracting 1 from the argument of f(x). This means that the graph of f(x+1) will be shifted 1 unit to the left compared to the graph of f(x).
Next, we have a vertical stretch by a factor of 2, since we are multiplying the output of f(x+1) by 2. This means that the graph of 2f(x+1) will be twice as tall as the graph of f(x+1).
Finally, we have a vertical shift downwards by 3 units, since we are subtracting 3 from the output of 2f(x+1). This means that the graph of h(x) will be shifted 3 units downwards compared to the graph of 2f(x+1).
To find where the point (2, 2) ends up after these transformations, we can first apply the horizontal shift of 1 unit to the left, which gives us the point (1, 2). Next, we apply the vertical stretch by a factor of 2, which gives us the point (1, 4). Finally, we apply the vertical shift downwards by 3 units, which gives us the point (1, 1).
Therefore, the point (2, 2) would end up at the point (1, 1) after the transformations.
To sketch the graph of h(x), we can start with the graph of f(x) and shift it 1 unit to the left, stretch it vertically by a factor of 2, and shift it 3 units downwards. The resulting graph will have the same shape as the graph of f(x), but will be shifted and scaled as described above. The point (1, 1) will be on this graph as well.

A. Regardless of the values of b and c, the point (-2,2) is included in the curve of g(x).
B. On the graph of h(x), the point (2,2) would be changed into the point (2,1).
What is graph?A graph is a graphical representation of data, functions, or variable connections. It is a method of displaying information that is simple to analyse and comprehend.
Graphs are widely used in a variety of disciplines, including science, economics, business, engineering, and others. They make it simpler for researchers and analysts to visualise data and identify trends or patterns, allowing them to draw conclusions and make educated choices based on the data.
A. To include the spot (-2,2), we must shift the f(x) graph two units to the right and two units up. So far, we have:
g(x) = a f(x - (-2)) + 2
g(x) = a f(x + 2) + 2
We must now determine the worth of "a." Because the point (3,4) on the f(x) graph is transferred to the point (2,2) on the g(x) graph, we have:
g(3) = a f(3 + 2) + 2 = 2
4a + 2 = 2
4a = 0
a = 0
Therefore, the function g(x) is:
g(x) = 0 f(x + 2) + 2
g(x) = 2
As a result, independent of the values of b and c, the point (-2,2) is included in the graph of g(x).
B. The function h(x) has a slope of 2 and a y-intercept of -1. We plug x=2 into h(x) to determine where the point (2,2) would end up after the transformations and get:
h(2) = 2(2+1)-3 = 1
As a result, the point (2,2) on the graph of h(x) would be changed to the point (2,1).
The transformations applied to f(x) to produce h(x) are a one-unit horizontal shift to the left (x+1), a two-unit vertical stretch (2(x+1)), and a three-unit vertical shift downwards (-3).

Find the volume of this sphere use 3 for pi 2ft
The volume of the sphere is 32/3 cubic feet.
What is Volume ?
Volume is a measure of the amount of space that a three-dimensional object takes up. It is typically measured in cubic units such as cubic meters, cubic centimeters, cubic feet, or cubic inches.
To find the volume of a sphere, we use the formula:
V = (4/3) * pi * [tex]r^{3}[/tex]
where V is the volume of the sphere, pi is the constant pi (3.14...), and r is the radius of the sphere.
In this case, the radius of the sphere is given as 2ft. So, substituting this value into the formula, we get:
V = (4/3) * 3 * [tex](2ft)^3[/tex]
= (4/3) * 3 * 8[tex]ft ^ 3[/tex]
= 32/3 [tex]ft ^ 3[/tex]
Therefore, the volume of the sphere is 32/3 cubic feet.

Explain why domain restrictions are necessary to create inverse trigonometric functions rather than relations.
This would make the inverse function a relation rather than a function, and it would fail the vertical line test.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It focuses on the study of trigonometric functions, which are functions that relate the angles of a triangle to the ratios of the lengths of its sides.
Inverse trigonometric functions are used to find the angle whose trigonometric ratio is given. For example, if we know that sin θ = 1/2, we can use the inverse sine function to find the angle θ, which is sin^-1(1/2) = 30°.
However, inverse functions must be functions, meaning that they must pass the vertical line test, where each input (x) produces exactly one output (y). To ensure that inverse trigonometric functions meet this criteria, we need to restrict the domain of the original trigonometric functions.
Trigonometric functions are not one-to-one functions, which means that multiple angles can produce the same value of a trigonometric ratio. For example, sin 30° = sin 150° = 1/2. If we were to define the inverse sine function as the inverse of the sin function without a domain restriction, we would have multiple possible outputs for the same input.
Therefore, this would make the inverse function a relation rather than a function, and it would fail the vertical line test.

(Scale Factor HC)
A rectangular oil painting is 14 inches wide and 24 inches long. A museum wants to create a larger print of the painting using a scale factor of 3.
Part A: What are the dimensions of the print, in feet? Show every step of your work. (2 points)
Part B: What is the area of the print, in square feet? Show every step of your work. (2 points)
Part A:
First, we need to find the dimensions of the print by multiplying the dimensions of the original painting by the scale factor of 3.
The width of the print is 14 inches x 3 = 42 inches
The length of the print is 24 inches x 3 = 72 inches
To convert these dimensions into feet, we need to divide by 12 (since there are 12 inches in a foot):
Width of print = 42 inches / 12 = 3.5 feet
Length of print = 72 inches / 12 = 6 feet
Therefore, the dimensions of the print are 3.5 feet by 6 feet.
Part B:
To find the area of the print, we need to multiply the width by the length:
Area of print = (3.5 feet) x (6 feet) = 21 square feet
Therefore, the area of the print is 21 square feet
