So on solving the provided question we can say that - the equation will be y = -120x^2 - 2500x + 80,000; x = 0 so, y = 80000
What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
y = -120x^2 - 2500x + 80,000
x = 0
so, y = 80000

What is System of Linear Equations?System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.
x y= -30............ (1)
and, x + y= 4 ...................(2)
So, x + (-30/x)= 4
x² - 30 = 4x
x² -4x -30 = 0
Solving the Quadratic Equation
x= (4 ±√4² - 4(1)(-30) / 2)
x= (4 ± √136)/ 2

a) The polygon has 11 sides
b) The Sum of the Interior Angles of the 11 sided Polygon = 1620 degrees
What is a polygon ?
The definition of a polygon is a closed, two-dimensional, plane shape created by connecting three or more line segments. During our study of geometry, polygons are a common sight.
A polygon's sides are constructed from segments of straight lines joined end to end. The sides or edges of a polygon are the line segments that make up its shape. The vertex or corners formed by two line segments are where an angle is created. A triangle with three sides is an illustration of a polygon.
There are 11 sides, So, n=11
Sum of the Interior Angles of a Polygon = 180 (n-2) degrees
So,
The Sum of the Interior Angles of the 11 sided Polygon

A family eats at a restaurant. The bill is $42. The family leaves a tip and spends $49.77. a.) How much was the tip in dollars?
b.) How much was the tip as a percentage of the bill?
The tip was $7.77 in total, and it is a 18.5% of the bill cost.
How much was the tip in dollars?Here we know that the bill was $42, while the family spend a total of $49.77
Then the amount for the tip is equal to the difference between the bill and the amount that the family spends.
Tip = $49.77 - $42 = $7.77
Now we want to see which percentage of the bill this is, to check that, we need to take the quotient between the tip and the bill, and multiply that by 100%, we will get:
percentage = ($7.77/$42)*100%
percentage = (0.185)*100% = 18.5%

what is is Riemann sum?A specific method of approximating an integral with a finite sum in mathematics is known as a Riemann sum. Riemann is the name of a German mathematician who lived in the 19th century. Approximating the area of functions or lines in graphs, as well as the length of curves and other approximations, is a highly typical application. The picked points in each subinterval of the partition are all in the upper Riemann sum, given an interval partition. The interval is often separated into subintervals of equal size.
Riemann sum formula is A=∑f(xi)Δx A = ∑ f ( x i ) Δ x ,

método descrito en la demostración del teorema del conjunto generador (sección 4.3) para producir una base de H. (Expli-que cómo seleccionar los elementos apropiados de S.)
Therefore, We can use the Gaussian elimination method to find the basis of H.
Define Gaussian elimination method.In linear and multilinear algebra, the procedure of Gauss elimination involves first solving one of the simultaneous linear equations for one variable (in terms of all the others) and then substituting this expression into the other equations to discover the answers.
Define linear equation.A linear equation is an algebraic equation in which each term has an exponent of 1, which, when plotted on a graph, always yields a straight line. One example with one variable is where ax+b = 0, where a and b are fundamental values and x is the variable.
Selecting the polynomials Pi(t) = 1 + t and P2(t) = 1 - t from the set S. These are linearly independent since they cannot be written as a linear combination of the other polynomials in the set and checking if the span of Pi(t) and P2(t) is equal to H. Then expressing the remaining
polynomials P3(t), P4(t), and Ps(t) in terms of Pi(t) and P2(t) and checking if they can be written as a linear combination of Pi(t) and P2(t) or not.
P3(t) = 4 can be written as 4 * Pi(t) - 4 * P2(t)
P4(t) = 1 + 7t can be written as Pi(t) + 7 * P2(t)
Ps(t) = 1 + 2t + 7t^2 can be written as Pi(t) + 2t * P2(t) + 7 * P2(t)^2
From this, we can see that all the polynomials in S can be written as a linear combination of Pi(t) and P2(t). So, the span of Pi(t) and P2(t) equals H. Hence, { Pi(t), P2(t) } is a basis for the subspace H.
