At the city Museum child omission is $5.70 and adult admission is $9.80. On Tuesday 124 tickets were sold for a total sales of $

936. How many child tickets were sold that day

Answer: 68 child tickets were sold

Step-by-step explanation:

Let x represent the number of child tickets that were sold that day.

Let y represent the number of adult tickets that were sold that day.

A total of 124 tickets were sold on Tuesday. This means that

x + y = 124

At the city Museum child admission is $5.70 and adult admission is $9.80. The total sales from tickets was $936. This means that

5.7x + 9.8y = 936 - - - - - - - - -1

Substituting x = 124 - y into equation 1, it becomes

5.7(124 - y) + 9.8y = 936

706.8 - 5.7y + 9.8y = 936

- 5.7y + 9.8y = 936 - 706.8

4.1y = 229.2

y = 229.2/4.1

y = 55.9

y = 56

x = 124 - y = 124 - 56

x = 68

A new restaurant is attracting customers with searchlights has a radius of 2 feet. What is the searchlights circumference?
Assoli18 [71]

Answer:

12.56 feet

Step-by-step explanation:

The perimeter of a shape is the sum of all its side.

Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".

The circumference of a circle has the formula:

C=2\pi r

Where

C is the circumference (perimeter of a circle)

r is the radius

Given,

r = 2 feet

We substitute and find the circumference, using 3.14 as \pi,

C=2\pi r\\C=2(3.14) (2)\\C=12.56

Hence, the circumference is 12.56 feet

How to factor a tri, quad, or polynomial.
Akimi4 [234]

Explanation:

Factoring to linear factors generally involves finding the roots of the polynomial.

The two rules that are taught in Algebra courses for finding real roots of polynomials are ...

  • Descartes' rule of signs: the number of positive real roots is equal to the number of coefficient sign changes when the polynomial is written in standard form.
  • Rational root theorem: possible rational roots will have a numerator magnitude that is a divisor of the constant, and a denominator magnitude that is a divisor of the leading coefficient when the coefficients of the polynomial are rational. (Trial and error will narrow the selection.)

In general, it is a difficult problem to find irrational real factors, and even more difficult to find complex factors. The methods for finding complex factors are not generally taught in beginning Algebra courses, but may be taught in some numerical analysis courses.

Formulas exist for finding the roots of quadratic, cubic, and quartic polynomials. Above 2nd degree, they tend to be difficult to use, and may produce results that are less than easy to use. (The real roots of a cubic may be expressed in terms of cube roots of a complex number, for example.)

__

Personally, I find a graphing calculator to be exceptionally useful for finding real roots. A suitable calculator can find irrational roots to calculator precision, and can use that capability to find a pair of complex roots if there is only one such pair.

There are web apps that will find all roots of virtually any polynomial of interest.

_____

<em>Additional comment</em>

Some algebra courses teach iterative methods for finding real zeros. These can include secant methods, bisection, and Newton's method iteration. There are anomalous cases that make use of these methods somewhat difficult, but they generally can work well if an approximate root value can be found.

What is function in math?

  • A quantitative expression, rule, or law that describes the link between an independent variable and a dependent variable (the dependent variable).
  • In mathematics, functions occur widespread, and they are essential for defining physical links in the sciences.
  • A function is a type of rule that generates one output for a single output.
  • This is represented by the equation y=x2. Any inputs for x result in an output for y. Given that x is the input value, we would state that y is a result of x.
