Fiesta28 [93]
Let's construct an equation for Canton's population increase as 7220+80n and Holly Spring's population increase with 3200+120n, where n is the number of years. We have to set these equations to each other in order to find when the population of these two places are equal. 3200+120n=7220+80n and n=100.5. After 100 and half years

Which expressions are polynomials?
Oduvanchick [21]

Answer:


Step-by-step explanation:

Definition : The expression that can have constants (like 4), variables (like x or y) and exponents (like the 2 in y^{2}), that can be combined using addition, subtraction, multiplication and division, but no division by a variable and a variable's exponents can only be 0,1,2,3,... etc. and it can't have an infinite number of terms.

1. 6 + p

Being p be a variable this equation is polynomial

2.  x – 1

Since x-1 has variable and constant so according to definition it is a polynomial

3. 8x−z3

According to definition it is a polynomial

4 .5x^{2}-x\sqrt{}

Since has root so it is not a polynomial .

A bag contains 13 pieces of candy. In how many ways can five pieces be selected?
Whitepunk [10]

Five pieces can be selected in 1287 ways

Step-by-step explanation:

When the selection has to be made without considering the order of selection, combinations are used.

The formula for combination is:

C(n,r) = \frac{n!}{r!(n-r)!}

Here

Total candies = n = 13

Candies to be selected = r = 5

Putting the values in the formula

C(13,5) = \frac{13!}{5!(13-5)!}\\=\frac{13!}{5!8!}\\=1287\ ways

Five pieces can be selected in 1287 ways
