What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.

f(x) = anxn + anxn+1 +... + a2x2 + a1x + a0 is the formula for a polynomial. The greatest power of x in an expression is the mathematical function's degree. Polynomials of degree 0, 1, 2, 3, and 4 are constant (non-zero) polynomials, linear polynomials, quadratics, cubics, and quartics, respectively.

When two or more algebraic terms are added, subtracted, or multiplied (no division! ), the result is a mathematical expression known as a polynomial. The majority of the time, polynomial expressions contain at least one variable.

Which type of burn is BEST described as having reddish skin, white border, and some pain? A. first-degree burn B. second-degree burn C. third-degree burn D. forth-degree burn Please select the best answer from the choices provided. A B C D

Answers

Answer:

The correct answer to this equation is A.

Explanation:

~Hope this helps :)

Second-degree burns also referred to as partial-thickness burns, are characterized by reddened skin with a white or pale border. Therefore option B is correct.

These burns affect both the outer layer of skin (epidermis) and a portion of the underlying layer (dermis).

The reddening of the skin is due to inflammation and increased blood flow, while the white or pale border results from the destruction of skin cells in the affected area.

Second-degree burns typically cause pain due to the involvement of nerve endings in the dermis. Blisters may also develop.

Unlike first-degree burns, which affect only the outermost layer of skin, second-degree burns involve deeper tissue layers, making them more severe and requiring appropriate medical attention for proper care and healing.

Therefore option B is correct.

how many grams of bacl2 are formed when 35.00 ml of 0.00237 m ba(oh)2 reacts with excess cl2 gas?

Answers

Explanation:

Answer:

0.0071g

Explanation:

From the question, we know that the molarity of the BaCl2 is 0.00237M. This means there are 0.00237 moles in 1dm^3 or 1000cm^3 of solution.

We also know that 35ml of the BaCl2 reacted. Here, we need to calculate the number of moles in 35.7ml of BaCl2.

This is calculated as follows;

0.00237moles are in 1000cm^3

Thus x moles will be present in 35ml ( we should note that cm^3 is same as ml)

X = (0.00237 × 35) ÷ 1000 = 0.00008295 moles.

From the reaction equation, we can see that 2 moles of BaCl2 yielded 1 mole of Ba(OH)2.

This means 0.00008295mole of BaCl2 will yield 0.00008295 ÷ 2 = 0.000041475 moles of Ba(OH)2.

To calculate the mass of Ba(OH)2 formed, we simple multiply the number of moles yielded by the molar mass of Ba(OH)2.

Molar mass of Ba(OH)2 = 137 + 2(17)

= 171g/mol

Mass = 171 × 0.000041475 = 0.007092225g
