Answer:

The possible arrangement can be done as -

2 rows, with 8 chairs in each row.
4 rows, with 4 chairs in each row.
8 rows, with 2 chairs in each row.

What is a Arrangement? What is equation modelling? What is a mathematical equation and expression?

Arrangement numbers, more commonly called permutation numbers, or simply permutations, are the number of ways that a number of things can be ordered or arranged.
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

A mathematical equation is used to equate two expressions.

Given is that a teacher wants to arrange 16 chairs in equal rows in his classroom.

The possible arrangement can be done as -

2 rows, with 8 chairs in each row.
4 rows, with 4 chairs in each row.
8 rows, with 2 chairs in each row.

Therefore, the possible arrangement can be done as -

2 rows, with 8 chairs in each row.
4 rows, with 4 chairs in each row.
8 rows, with 2 chairs in each row.

The line of symmetry that divides a parabola in half as "The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola".

What is parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. A parabola can be described using a point and a line. Three different parabolas exist. Vertex form, standard form, and intercept form are the three forms. You can access a unique key feature for the graph on each form. A parabola's general equation is written as y = a(x - h)² + k or x = a(y - k)²+ h. Vertex here is indicated by (h, k).

A student is offered two different summer jobs. Job A lasts 16 weeks and pays $350.00 per week. Job B lasts 4 months and pays $1,500.00 per month, with monthly raises of 10% of the previous month's salary. How much more does the student earn by accepting Job B (rounded to the nearest cent)?

The required, by accepting job B a student can earn $1361.5 more than Job A.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

here,
Job B lasts 4 months and pays $1,500.00 per month, with monthly raises of 10% of the previous month's salary.
Total earnings in 4 months,
= 1500 + 1.1×1500 + 1.1 [1.1×1500] + 1.1×[ 1.1 [1.1×1500] ].
= $6961.5

Job A lasts 16 weeks and pays $350.00 per week.
Total earnings in 16 weeks,
= 16 × 350 = $5600

The difference in earning = Job B - Job A
= 6961.5 - 5600
= 1361.5

Thus, the required, by accepting job B a student can earn $1361.5 more than Job A.

Both last 4 months.

Job B = $412.50per/week

Job A = $1600per/month

1650*1.1 = 1815 Month 2's paycheck

1815*1.1 = 1996.5 Month's 3 Paycheck

1996.5*1.1 = 2196.15 Month 4's paycheck

1600*4 = $6400 Job A total

1650+1815+1996.5+2196.15 = $7657.65 Job B total

7657.65-6400 = 1257.65

$1257.65 more thant Job A
