Answer: 361000

Step-by-step explanation:

The indicated left sum for the given function on the indicated interval, the value L4 for f(x) = 1/x-1on [3, 4] L4 = 0.7595.

Let Ln denote the left-endpoint sum using n sub intervals.

We are given that

[tex]f(x) = \frac{1}{x-1}[/tex]  [3,4]

We have to find L4

It means n = 4

x = [tex]\frac{b-a}{n} = \frac{4-3}{4} = \frac{1}{4}[/tex] = 0.25

Now, intervals are

[3, 3.25], [3.25, 3.50], [3.5, 3.75], [3.75, 4]

Now,

[tex]L_{4} = f(x_{0}) \triangle x+f(x_{1})\triangle x +f(x_{2})\triangle x+f(x_{3})\triangle x\\ \\ L_{4} = \frac{1}{3-1} (0.25)+\frac{1}{3.25-1}(0.25)+\frac{1}{3.5-1}(0.25)+\frac{1}{3.75-1}(0.25)\\ \\ L_{4} = 0.7595[/tex]

Hence the answer is the indicated left sum for the given function on the indicated interval, the value L4 for f(x) = 1/x-1on [3, 4] L4 = 0.7595.

The equation represent the given situation is y=3x+10.

What is equation?

   A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Here let us take the values of time and amount as x and y. Then take any two points ,

[tex](x_1,y_1)=(3,19)\\(x_2,y_2)=(6,28)[/tex]

Now using slope formula,

=> slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> slope m = 9/3 = 3

Now using equation formula ,

=> [tex]y-y_1=m(x-x_1)[/tex]

=> y-19=3(x-3)

=>y-19=3x-9

=>y=3x-9+19

=>y=3x+10

Hence the correct option is A)y=3x+10.

He can buy 5 candy at most with this inequality 2c-3<9 as the inequality will result in c<6 as the definition of inequality says, "In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another".

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another. The equation-like form of the expression 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3. The greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), and not equal to symbol () are the five inequality symbols. Take the same amount away from both sides. Add the same positive number to both sides. Subtract the same positive number from both sides. Reverse the sign and multiply both sides by the same negative number.

Here,

2c-3<9

add 3 both side,

2c-3+3<9+3

We are given the following information.

We also know that the general equation of a line is given by

Where m is the slope of the line and b is the point at which it crosses the y axis.

Since the line given goes through (0,0), b=0. Now we just need to find m.

This can be done via the formula

In this case

And so, the equation of the line given is

Now we simply need to see which of the options fit this equation. We can do this easily, because x and y are equal except for their sign.

As such, the point of the terminal side of 135° is (-1,1).

If linear function can be modeled using the equation 2x-y=2. Then x=1 is the Zero of this function

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

2x-y=2

We need to write this in slope intercept form

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

y=2x-2

m=2 and y intercept is -2

Now take the values of x and y

x       0       1         2         3

The answer will be [tex]4^{30}[/tex]  different ways can the question be answered using permutation.

What is permutation?

A permutation is both an ordered combination and an ordered arrangement of results. For instance, 3 people are to sit in each of the 5 chairs. The first person can be seated in five different ways, the second person in four different ways, and the third person in three different ways. Accordingly, generalising this, we obtain n alternatives to fill the first chair, n-1 options to fill the second, and n-2 options to fill the third chair. As a result, nPr = n! / (n - r)! can be used to represent how many different permutations (arrangements) there are when there are r individuals and n chairs.

Each question has four choices. So, the total number of ways in which the questions can be attempted is [tex]4^{30}[/tex]

A quadratic function has the generic form f(x)=ax²+bx+c. A parabola, a kind of two-dimensional curve, is the graph of a quadratic function. A polynomial function of degree two in one or more variables is known in algebra as a quadratic function, quadratic polynomial, polynomial of degree 2, or simply a quadratic. The phrase "quadratic" in mathematics refers to something that has to do with squares, the squaring operation, terms of the second degree, or equations or formulas that contain such terms. Latin's word for square is quadratus.
