Step-by-Step:

Value of f[g(x-1)] is 2x^2-4x+9. The solution has been obtained by applying the multiplication operation on functions and substituting the functions.

Just like we add, subtract, multiply and divide the terms in a function, the functions can also be added, subtracted, multiplied or divided in a similar way.

Suppose there are two functions f(x) and g(x). The notations are as follows:

For Addition: (f+g)(x) = f(x) + g(x)

For Subtraction: (f-g)(x) = f(x) - g(x)

For Multiplication: (f×g)(x) = f(x) × g(x)

For Division: (f/g)(x) = (f(x))/(g(x))

When we substitute one function into another, a function is generated in which one function is considered to be a part of another function.

Now, f(g) = 2g-3

We are given g = x^2+5

So, g(x-1) = (x-1)^2+5

Substituting the value of g(x-1) in f(g), we get

f(g(x-1)) = 2((x-1)^2+5)-3

= 2x^2-4x+9

Hence, the value of f[g(x-1)] is 2x^2-4x+9.

The correlation coefficient r = +0.9 indicates a strong positive correlation as a strong positive (negative) linear relationship is shown by values between 0.7 and 1.0 (or -0.7 and -1.0).

What is corelation coefficient?

A statistical concept known as the correlation coefficient aids in establishing a relationship between expected and actual values gained through statistical experimentation. The estimated correlation coefficient's value explains how well the expected and actual values match.

The following points are the accepted guidelines for interpreting the correlation coefficient  -

1. Zero means there is no linear relationship.

2. A perfect positive linear relationship, or one with a value of 1, means that as one variable rises in value, the other variable rises in value according to an exact linear law.

3. A perfect negative linear relationship is represented by a value of 1; as one variable's values rise, the other variable's values fall according to an exact linear law.

4. Values between 0 and 0.3 (0 and -0.3) denote a wobbly linear rule with a weak positive (negative) linear relationship.

5. A fuzzy-firm linear rule indicates a somewhat positive (negative) linear relationship for values between 0.3 and 0.7 (-0.3 and -0.7).

6. A strong positive (negative) linear relationship is shown by values between 0.7 and 1.0 (or 0.7 and 1.0) by a strict linear rule.

Answer:I don’t know I just need points

Step-by-step explanation:

Christine has 262 pieces of bread, 336 lice of patrami, and 302 lice of cheese, so she can make a maximum of 131 hero sandwiches if each sandwich consist of two pieces of bread, two slices of patrami, and two slices of cheese.

Therefore the answer is 131.

Christine is making hero sandwiches, each of which consist of two pieces of bread, two slices of patrami, and two slices of cheese. To find the greatest number of heroes he can make, we need to divide the total number of each ingredient by the number of that ingredient used in each sandwich.

The number of heroes Christine can make with the bread is:

262 pieces of bread / 2 pieces of bread per hero = 131 heroes

The number of heroes Christine can make with the patrami is:

336 slices of patrami / 2 slices of patrami per hero = 168 heroes

The number of heroes Christine can make with the cheese is:

302 slices of cheese / 2 slices of cheese per hero = 151 heroes

To find the greatest number of heroes Christine can make, we need to take the smallest of these three values, which is 131 heroes. This means that Christine can make a maximum of 131 heroes with the ingredients he has on hand.

Then the two solutions are: x = (4 + 5.66) / 8 = 11.2075  and x = (4 - 5.66) / 8 = -0.2075

The sine approximation formula of Bhaskara I is a rational equation in one variable for computing the approximations of the trigonometric sines found by Bhaskara I (c. 600–c. 680), an Indian mathematician of the seventh century.

Indian astronomer and mathematician Bhaskara II lived in the 12th century. He created a number of the same foundations and findings that are entirely attributable to Europeans and are still very helpful in modern science and forecasts, such as a basic form of calculus.

Here we have the equation:

y = 4 × x² - 4 × x - 1

And the graph should be available (you can see it below this answer)

Now, we're seeking answers to:

4 × x²- 4 × x - 1 = 0

The two x values at which the graph of our function intersects the y = 0 line, or the x-axis, will be these solutions.

The next step is to identify the two x values where our graph crosses the x-axis.

We can estimate the solutions in the graph as follows:

x = -0.2

x = 1.2

The Bhaskara's equation can be used to determine the precise solutions, and we will discover that the solutions are provided by:

[tex]$x=\frac{-(-4)+-\sqrt{(-4)^2-4 * 4 *(-1)}}{2 * 4}=\frac{4+-\sqrt{32}}{8}=\frac{4+-5.66}{8}[/tex]

Step-by-step explanation:

The tent consists of a cylinder at the bottom and the roof of the tent is a cone

The height of the cone = 2h - h = h which is the same as the height of the cylindrical part

Volume of a cylinder = πr²h where r = radius, h- height

We are given this volume = 300 m³

The volume of a cone is (1/3)πr²h

If the heights and radius are the same, the volume of the cone is 1/3 the volume of the cylinder

Volume of conical part of tent = 1/3 x volume of cylindrical part

= 1/3 x 300 = 100 m³

Total volume of the tent and therefore the volume of air

= 300 + 100 = 400 m³

The law of cosines serves as a generalization of the Pythagorean formula, which is applicable to all triangles.

Compare the total of the squares on the two smaller sides to the square on the largest side to determine if the triangle is acute, right, or obtuse. Because of the larger sum, the triangle is sharp.

The Pythagorean formula applies to all triangles and is generalised by the law of cosines. The square of one side of the triangle, c², is said to be equal to a² + b², the sum of the squares of the other two sides, minus 2ab cos C, which is the product of the two squares times the cosine of the opposite angle.

Three closed sides make up a triangle. The Pythagoras theorem and the Heron's formula are two significant formulas that pertain to triangles.

Provided the given distance and the angle of elevation, Using the trigonometry in the right angled triangle formed, The answer is 74.89 feet.

Trigonometry is the branch of mathematics that deals with the relationships between the angles and sides of triangles, particularly right triangles. Trigonometry is used to study properties such as lengths, angles, and areas of triangles and the relationships between them. It is also used in many fields, including physics, engineering, and navigation. Trigonometry is based on the study of the ratios of the sides of a right triangle. The three main ratios are sine, cosine, and tangent. These ratios are defined using the right triangle's angles and are often abbreviated as sin, cos, and tan. In addition to these three main ratios, there are also several other trigonometric functions, including cosecant, secant, and cotangent. These functions are the reciprocals of the sine, cosine, and tangent functions, respectively.

A right triangle is a type of triangle that has one angle that measures exactly 90 degrees. This angle is called the right angle and the two sides that form the angle are called the legs of the triangle. The side opposite the right angle is called the hypotenuse. A right triangle can also be defined as a triangle that has a 90-degree angle and two acute angles. The legs of the triangle are the sides that are opposite the acute angles, and the hypotenuse is the side that is opposite the right angle.

By using the numbers 3, 1, and 4, you are able to get the answer 81

So, 175 children's tickets were sold, and 100 adult tickets were sold.

We can start solving the problem by using a system of equations. Let x be the number of children's tickets and y be the number of adult tickets. We know that:

x + y = 275 (the total number of tickets sold)

3x + 5y = 1025 (the total value of the tickets sold)

To find the number of each type of ticket sold, we can use the first equation to express one of the variables in terms of the other, and then substitute that into the second equation. For example, we can express y in terms of x:

y = 275 - x

Now we can substitute this into the second equation and solve for x:

3x + 5(275 - x) = 1025

3x + 1375 - 5x = 1025

-2x = -350

x = 175

So, 175 children's tickets were sold, and 275 - 175 = 100 adult tickets were sold.

The section formula provides a way to check if three points in 3D space are collinear by verifying that the equation (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0 is satisfied when their coordinates are substituted.

To prove three points are collinear in 3D using the section formula, first determine the coordinates of the three points. Then, substitute the coordinates into the section formula equation, (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0. Finally, calculate the equation and if it is equal to 0, the three points are collinear.

For example, if the coordinates of three points are (x1, y1, z1), (x2, y2, z2) and (x3, y3, z3), then the three points are collinear if the following equation is satisfied:

(x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0

If the equation is not equal to 0, the points are not collinear. To illustrate, if the coordinates of three points are

(x1, y1, z1), (x2, y2, z2) and (x3, y3, z3),

then the three points are collinear if the following equation is satisfied: (x2 - x1)(y3 - y1) - (x3 - x1)(y2 - y1) = 0.
