Answer:

x^3y and  x^2y^2

Step-by-step explanation:

An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.

The given polynomial is: 8x^3y^2----------+3xy^2

We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.

-4y^3

x^2y^2

x^3y

7x^2y

7x^0y^3

A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.

Since the first term of  8x^3y^2----------+3xy^2 having a degree of 5 and the last term is having a degree of 3.

The polynomial that goes into the blank must have a degree of 4.

This eliminates -4y^3, 7x^2y

and 7x^0y^3

We are now left with x^2y^2 and x^3y

The required polynomial is therefore 8x^3y^2-x^2y^2+3xy^2 or8x^3y^2-x^3y+3xy^2

These two polynomials are in standard form and cannot be simplified further.

The correct choices are;

x^3y and  x^2y^2

Which expression is equivalent to 7h^2-252k^2?
gulaghasi [49]

Answer:

c

Step-by-step explanation:

252 = 7 *36

36 = 6 *6 = 6²

a² -b²  = (a + b)(a - b)

7h² - 252k² =  7(h² - 36k²)

                   = 7(h² - [6k]² )

                  = 7(h  +6k)(h - 6k)

A stock has had returns of 7 percent, 25 percent, 17 percent, −13 percent, 25 percent, and −6 percent over the last six years. W
Tems11 [23]

Answer: Geometric average return would be 0.10% and arithmetic average return would be 9.17%.

Step-by-step explanation:

Since we have given that

Returns are as follows:

7%, 25%, 175, -13%, 25% and -6%.

Geometric return is given by

\sqrt[6]{(1+0.07)(1+0.25)(1+0.17)(1-0.13)(1+0.25)(1-0.06)}-1\\\\=\sqrt[6]{(1.17)(1.25)(1.17)(0.87)(1.25)(0.94)}-1\\\\=0.097\%=0.10\%

Arithmetic average return would be

\dfrac{7+25+17-13+25-6}{6}=9.17\%

Hence, geometric average return would be 0.10% and arithmetic average return would be 9.17%.
