A polynomial is a kind of algebraic expression in which the exponents of all variables should be a whole number.

The Power of the variables in any polynomial has to be a non-negative integer. A polynomial consists of constants and variables, but we cannot perform division operations by a variable in polynomials.

The example of polynomial is: 3x^2 + 5.

given the equation is x^3+3^2+3x.=0

                              (x³-x) +(3x²-3) =0

                              = x (x²-1) +3(x²-1)

                               = (x²-1) (x+3) = 0

                               (a² + b²) = (a+b) (a-b)

                               (x²-1) = (x+1) (x-1)

                              ⇒(x+1) (x-1) (x+3) =0

                               x =- 3, -1, 1

So, the required zeros are -3, -1,1.

Calculus in baseball. In baseball, calculus can be used to optimize the pitcher’s throw to achieve maximum efficiency. Also, calculus can be used to calculate the projectile motion of baseball’s trajectory and to predict if runners can make it to the next base on time given their running speed and the speed of a hit ball.

Step-by-step explanation:

The solution to the given system of linear equations is x = -4, y = -10

From the question, we are to solve the given system of linear equations.

The given system of linear equations is

y = 2x - 2          ------------ (1)

-4x - y = 26     ------------ (2)

Substitute equation (1) into equation (2)

-4x - y = 26

-4x - (2x - 2) = 26

- 4x - 2x + 2 = 26

-6x + 2 = 26

-6x = 26 - 2

-6x = 24

x = 24/-6

x = -4

Substitute the value x into equation (1)

y = 2(-4) - 2

y = -8 - 2

y = -10

Hence, the x = -4, and y = -10

The exponential form of 10 * 10 is [tex]10^{2}[/tex] . We get it from the prime factorization.

In order to get the exponential form of a number we have to write the prime factorization of that number. Prime factorization of the number is that number written as a product of prime numbers or as a product of powers of prime numbers. A basic exponential function from its definition is of the form f(x) = b x, where 'b' is a constant and 'x' is a variable. generally it refers to the positive valued function of a real variable. We can find the prime factorization of a number using factor trees, which are tools used to repeatedly break a number into products until all of the factors are prime numbers.

The area of a triangle with sides 3 cm, 4 cm, and 5 cm is 6 cm² using Heron's formula.

Step 1: First, calculate the semi-perimeter of the triangle by adding the three sides of the triangle together and dividing by 2. In this case, the semi-perimeter would be (3 + 4 + 5) / 2 = 6 cm.

Step 2: Next, use the semi-perimeter and the three side lengths of the triangle to calculate the area. The formula for Heron's formula is:

Area = √(s(s-a)(s-b)(s-c))

Where s is the semi-perimeter, and a, b, and c are the three sides of the triangle.

So, plug in the values,

Area = √(6(6-3)(6-4)(6-5))

Area = √(632×1)

Area = √(36)

Area = 6 cm²

Therefore, the area of the triangle is 6 cm²

Total 24 minutes, x, will it take before the balloon has shrunk to a diameter of 8 feet.

In the given question, we have to find how many minute, x, will it take before the balloon has shrunk to a diameter of 8 feet.

From the given question, a hot-air balloon has a 14-foot diameter.

Hot-air balloon is being deflated at a rate of 0.25 feet per minute.

So the slope will be = -0.25, the negative sign is there because hot-air balloon is being deflated.

Let the amount of air left in the hot-air balloon at time n minutes is A(n) feet diameter.

The initial value of A(n) is 14-foot diameter.

Thus when n = 0, the value A(n) will be 14.

So, we can write the relation as

A(n) = -0.25n + 14

We need to find the amount left after x minute. So n = x.

The balloon has shrunk to a diameter of 8 feet. So A(n) = 8 feet

Now the equation is

8 = -0.25x + 14

Subtract 14 on both side, we get

-0.25x = -6

Divide by -0.25 on both side, we get

x = 24

The number of guitarist who plays classical solos in the contest is 30.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

The ratio of a and b is denoted as a : b.

Given that,

Total number of musicians entered in the contest = 64

5/8 of these musicians are guitarists.

Number of guitarists = (5/8) × 64 = 40

Also we have,

Ratio of number of guitarists playing jazz solos to the total number of guitarists = 1 : 4 = 1/4

That is, of the 4 guitarists, 1 is a guitarist playing jazz solos.

Multiplying both numerator and denominator with 10, 1/4 = 10/40

So of the 40 guitarists, 10 number of guitarists play jazz solos.

Number of guitarists who play classical solos = 40 - 10 = 30

Number of members = x

The total amount raised by all the members = p

nx + m = p

This is similar to the equation 300x + 750 = 23,250

So,

n = 300

m = 750
