Step-by-step explanation:

To find the length of the square side lengths and the diameter of the circle, we can divide the perimeter by 4:

79.04/4 = 19.76

This is the diameter of the circle. The radius is half the diameter:

19.76/2 = 9.88

Hope this helps!

Answer: 9.88 cm

Step-by-step explanation:

To find the radius, we need to find half the length of one side of the square.

The perimeter of the square is all the sides of the square added together.

Squares have 4 sides so divide the perimeter by 4 to find the length of 1 side.

79.04 / 4 = 19.76 is the length of one side.

Half of 19.76 is 9.88 so the radius of the circle is 9.88 cm.

Step-by-step explanation:

The expected value of the game in which you have a (1/20) chance of winning  is $1.50.  The probability of a student scoring between 75 and 89 is 0.5536. The probability of a student scoring above 85 is 0.4562.

1. To find the expected value of the game, we need to multiply the probability of each outcome by the value of that outcome and then add them together.

E(X) = (1/20)($300 + $15) + (19/20)(-$15)

E(X) = $315/20 - $285/20

E(X) = $30/20

E(X) = $1.50

So the expected value of the game is $1.50.

2. To find the probability of a student scoring between 75 and 89, we need to use the z-score formula:

z = (x - μ)/σ

For x = 75, z = (75 - 84)/9 = -1

For x = 89, z = (89 - 84)/9 = 0.56

Using a z-table, we can find the probability of a student scoring between these two z-scores:

P(-1 < z < 0.56) = P(z < 0.56) - P(z < -1)

P(-1 < z < 0.56) = 0.7123 - 0.1587

P(-1 < z < 0.56) = 0.5536

So the probability of a student scoring between 75 and 89 is 0.5536.

3. To find the probability of a student scoring above 85, we need to use the z-score formula:

z = (x - μ)/σ

For x = 85, z = (85 - 84)/9 = 0.11

Using a z-table, we can find the probability of a student scoring above this z-score:

P(z > 0.11) = 1 - P(z < 0.11)

P(z > 0.11) = 1 - 0.5438

P(z > 0.11) = 0.4562

So the probability of a student scoring above 85 is 0.4562.

The maximum value of the objective function is 73 when x=4 and y=17 and minimum value  is 21 when x=1 and y=5.

To find the maximum and minimum values of the objective function F=5y−4x, we need to use the constraints given in the question and solve for x and y. The constraints are y≤4x+1, y≥−4x+5, and x≤4.

First, we need to graph the constraints to find the feasible region. The feasible region is the area on the graph where all the constraints are satisfied.

Next, we need to find the corner points of the feasible region. The corner points are where the constraints intersect. The corner points are (1, 5), (4, 17), and (4, 11).

Finally, we need to plug in the corner points into the objective function to find the maximum and minimum values.

F(1, 5) = 5(5) - 4(1) = 21
F(4, 17) = 5(17) - 4(4) = 73
F(4, 11) = 5(11) - 4(4) = 47

The correct equation that describes the relationship in the table is option B, which is y = x2 + 3.

An equation is a mathematical statement that expresses the relationship between two or more variables. Equations are used to solve problems and represent real-world relationships.

To understand why this is the correct equation, it is important to look at the values of x and y in the table. When x increases by one, the value of y increases by the same amount. This indicates that the relationship between x and y is one of direct proportionality, wherein the value of y is directly proportional to the value of x. This can be expressed mathematically as y = kx, where k is a constant.

We can also look at the values of x and y in the table to determine the value of k. When x increases from 2 to 3, the value of y increases from 7 to 17. This means that k = 10. This can be written as y = 10x.

The value of y when x = 0 is 3, which is the constant term. This can be written as y = 10x + 3.

Therefore, the equation that describes the relationship in the table is y = x2 + 3.

(3/4)/(1/2) (quart/oz)

(3/4)/(1/2) can be written as:  (3/4)*(2/1)  [Invert the denominator and multiply]

Step-by-step explanation:

so, let me retype this.

horizontal asymptote : y = 2

that means lim x going to ±infinity f(x) = 2.

vertical asymptotes :

x = 3

x = -4

that means the function must have these 2 points, where the expression leads to a division by 0 or something similar that would make the result undefined.

we got 4 functions :

A) y = x²/(x² + x - 12)

B) y = x²/(x² - x - 12)

C) y = 2x²/(x² + x - 12)

D) y = 2x²/(x² - x - 12)

so, for which ones we have y = 2 as limit when x goes against + or - infinity ?

that would be C and D.

A and B lead to x²/x² = 1 as limit for gigantic numbers.

C and D lead to 2x²/x² = 2 as limit.

remember, when x gets really, really big, the "±x - 12" part becomes irrelevant.

so, we look at C and D.

which one lead to a division by 0 at x = 3 and x = -4 ?

that would be C.

for x = 3

x² + x - 12 = 3² + 3 - 12 = 9 + 3 - 12 = 12 - 12 = 0

for x = -4

x² + x - 12 = (-4)² - 4 - 12 = 16 - 4 - 12 = 12 - 12 = 0

D with x² - x - 12 would have x = -3 and x = 4 as zeroes.

these are different asymptotes than requested.

The measure of the angle ∠Z will be 88°.

Geometry is the study of two-dimensional and three-dimensional figures such as quadrilaterals, triangles, circles, their sides, and angles. Symmetry is defined as if the object is cut by its centre line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.

Given that the two angles are (9p + 20)° and (7p + 32 )°. The value of angle z is calculated as,

9p + 20 + 7p + 32 = 180

16p = 180 - 20 - 32

16p = 128

p = 8

The measure of the angle ∠Z will be,

9p + 20 + ∠Z= 180

72 + 20 + ∠Z= 180

∠Z = 180 - 72 - 20

∠Z = 88°

The polynomial g(x) can be written as the product of linear factors g(x) = (x - 5)(x - 1)(x + 3). Polynomial as the product of linear factors. g(x) = x3 – 3x2 + x + 5 g(x) = (x - 5)(x - 1)(x + 3) and all the zeroes of the function are x = 5, 1, and -3.

To find the zeros of a function, we need to set each factor of the polynomial to zero and solve for x. When x = 5, (x - 5) = 0, when x = 1, (x - 1) = 0, and when x = -3, (x + 3) = 0.

Therefore, the zeros of the function are x = 5, 1, and -3. We can use these zeros to graph the function, as each zero is a point on the x-axis. The graph of this function will have three x-intercepts at the given points. We can also use the zeros to find the y-intercept, which will be the constant term in the polynomial.

In this case, the constant term is 5, so the y-intercept will be (0, 5) the polynomial g(x) = (x - 5)(x - 1)(x + 3) has zeros at x = 5, 1, and -3, and a y-intercept at (0, 5).

Hence, we can learn vital information about the behaviour and shape of a polynomial function's graph by scrutinising its factors and other characteristics.

A polynomial function's factors include crucial details about the function graph. The factors specifically determine the locations where the graph intersects the x-axis, known as the function's roots or x-intercepts. By setting each factor to zero and calculating the associated value of x, these roots can be discovered.

The behaviour and structure of the graph are also influenced by the degree of the polynomial function, the signs of its leading coefficient, and other coefficients. The number of turning points in the graph, for instance, is determined by the degree of the polynomial function, whereas the concavity or convexity of the graph is determined by the leading coefficient and other coefficients' signs.

The variables to use in a model depend on the type of model being developed and the problem being addressed. In general, variables are the inputs to a model that are used to predict the outputs or dependent variables.

In statistical models, the independent variables, also known as predictors or features, are chosen based on their ability to explain the variability in the dependent variable. For example, in a linear regression model, the independent variables may include factors such as age, income, education, and gender, which are thought to be related to the dependent variable, such as the likelihood of purchasing a product.

In machine learning models, the variables may include a wide range of features, such as text, images, or sensor data, that are used to make predictions or classifications. The process of selecting the most relevant features, also known as feature selection, is an important step in developing effective models that can generalize well to new data.

Ultimately, the choice of variables depends on the specific problem being addressed, and may involve a combination of domain expertise, statistical analysis, and machine learning techniques to identify the most important predictors or features.

Answer:

To determine whether the given triangle is a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

Let's label the sides of the triangle as follows:

side a = 40 inches

side b = 75 inches

side c = 85 inches (the longest side)

Now we can apply the Pythagorean theorem:

c^2 = a^2 + b^2

85^2 = 40^2 + 75^2

7225 = 1600 + 5625

7225 = 7225

Since the equation is true, we can conclude that the given triangle is a right triangle.

Answer: yes

Step-by-step explanation:

To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.

a^2 + b^2 = c^2

c is the hypotenuse, the longest side of a right triangle.

a and b are the legs of the right triangle.

40²+75²=85²

Step-by-step explanation:

Let's use the variable "a" to represent the number of stamps Angela has.

From the problem, we know that Nicolas has 48 stamps, and that this is 2 times 5 less than the number of stamps Angela has. "2 times 5 less than the number of stamps Angela has" can be written as:

2(a - 5)

So the equation that relates the number of stamps Nicolas and Angela have is:

48 = 2(a - 5)

We can simplify this equation by first distributing the 2:

48 = 2a - 10

Then, we can add 10 to both sides of the equation:

58 = 2a

Finally, we can solve for a by dividing both sides by 2:

a = 29

Therefore, the equation we can use to find the number of stamps Angela has is:

2(a - 5) = 48

or, simplified:

a = 29

(a) It is possible to form a triangle with the angle measures, 30°, 80°, 70°

It is not possible for all such triangles to be congruent.

(b) It is possible to form a triangle with the angle measures, 20°, 105°, 55°

It is not possible for all such triangles to be congruent.

(c) It is not possible to form a triangle with the side lengths, 4cm, 3cm, 8cm

(d) It is possible to form a triangle with these side lengths.

All such triangles are congruent

From the question, we are to determine if it is possible for a triangle to have the given angle measures or side lengths

(a) To determine if a triangle can have the angle measures 30°, 80°, and 70°, we add the angles together to see if they equal 180°, the total degrees of a triangle.

30° + 80° + 70° = 180°

Since the angle measures add up to 180°, it is possible to form a triangle with these angle measures.

It is not possible for all such triangles to be congruent, since triangles with the same angle measures can have different side lengths.

(b) To determine if a triangle can have the angle measures 20°, 105°, and 55°, we add the angles together to see if they equal 180°.

20° + 105° + 55° = 180°

Since the angle measures add up to 180°, it is possible to form a triangle with these angle measures. However, it is not possible for all such triangles to be congruent, since triangles with the same angle measures can have different side lengths.

(c) To determine if a triangle can have side lengths 4cm, 3cm, and 8cm, we apply the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

4cm + 3cm > 8cm

4cm + 8cm > 3cm

3cm + 8cm > 4cm

Since all three inequalities are not satisfied (4 + 3 = 7 is not greater than 8, which is the longest side), it is not possible to form a triangle with these side lengths.

(d) To determine if a triangle can have side lengths 8cm, 15cm, and 17cm, we apply the triangle inequality theorem.

8cm + 15cm > 17cm

8cm + 17cm > 15cm

15cm + 17cm > 8cm

Since all three inequalities are satisfied, it is possible to form a triangle with these side lengths.

All such triangles are congruent, since these side lengths satisfy the conditions for a unique triangle known as a Pythagorean triple.

Hence, the triangle with side lengths 8cm, 15cm, and 17cm is a right triangle, and all right triangles with these side lengths are congruent by the Pythagorean theorem.

Ben's ball lands approximately 2.5 seconds after Andrew's ball.

Since the value of parameter a is -5 for both balls, the height of each ball follows the equation:

h(t) = -5t² + vt + h0

where;

Let's assume that Andrew's ball is hit with an initial velocity of v1, and Ben's ball is hit with an initial velocity of v₂. We also know that Ben's ball reaches a maximum height 50% greater than Andrew's, which means that:

h_max2 = 1.5h_max1

At the maximum height, the velocity of the ball is zero, so we can find the time it takes for each ball to reach the maximum height by setting v = 0 in the equation for h(t):

t_max1 = v₁ / (2 x 5)

t_max2 = v₂ / (2 x 5)

Since Ben's ball reaches a maximum height that is 50% greater than Andrew's, we can write:

h_max2 = 1.5h_max1

-5(t_max2)² + v₂t_max2 + h0 = 1.5(-5(t_max1)² + v1 * t_max1 + h0)

Simplifying this equation, we get:

-5(t_max2)² + v₂t_max2 = -7.5(t_max1)² + 1.5v₁t_max1

We also know that Andrew's ball lands after 4 seconds, which means that h(4) = 0:

h(4) = -5(4)² + v1 * 4 = 0

-80 + 4v1 = 0

v1 = 80/4

v1 = 20 m/s

Solving these equations for t_max2 and v2, we get:

t_max1 = v1 / (2 x 5)

t_max1 = 20 / (2 x 5)  = 2 s

t_max2 = 1.5 * t_max1 = 3 s

v2 = 1.5 * v1 = 30 m/s

To find the time it takes for Ben's ball to land, we need to find the time t2 when h(t2) = 0.

We can use the equation for h(t) with v = v2, h0 = 0, and solve for t:

-5t² + v₂t = 0

-5t² + 30 = 0

5t² = 30

t² = 30/5

t² = 6

t = √6

t = 2.5 s

Therefore, Ben's ball lands approximately 2.5 seconds after Andrew's ball.

Always double-check your graph by entering various x values and ensuring that the associated y values fall along the curve you drew.

A graph is a picture of data that illustrates the connection between two or more factors. A graph in mathematics is typically a two-dimensional coordinate system with a horizontal x-axis and vertical y-axis (vertical). Data points are represented on a graph by points that are drawn with their x- and y-coordinates. The graph can be used to display trends, correlations, and temporal shifts as well as other patterns and connections between the variables. Graphs are used to aid in the interpretation and communication of data in a wide range of disciplines, including mathematics, science, economics, and social studies.

Locate the vertex: The vertex of a quadratic function is the lowest or highest spot on the graph. For the x-coordinate of the vertex, use the expression x = -b / (2a), and for the y-coordinate, use y = f(x), where f(x) is the quadratic function.

The places where the graph crosses the x-axis and the y-axis are known as the intercepts. If x = 0, then calculate f to determine the y-intercept (0).

Additional information: Plug a few x values into the function to determine the associated y values. You'll have more data points to display on the graph as a result.
