Step-by-step explanation:

Choose the polynomial that is written in standard form.−3x5y2 + 4x3y + 10x2
−8xy2 + 4x4y2 + 3x3
x4y2 + 4x3y5 + 10x4
x6y2 + 4x3y8 + 10x7

Answers

Answer:

Option A is the correct option.

Step-by-step explanation:

Polynomials given in the question are

1) -3x^(5)y^(2)+4x^(3)y+10x^(2)

2) -8xy^(2)+4x^(4)y^(2)+3x^(3)

3) x^(4)y^(2)+4x^(3)y^(5)+10x^(4)

4) x^(6)y^(2)+4x^(3)y^(8)+10x^(7)

In a standard form of a polynomial term with the highest degree should be written first, then second highest degree term and similarly other terms should be written.

Here 1st polynomial is in the standard form only in which degree of terms are as followed.

1 term 3x^(5)y^(2) degree of term = (5 +2) = 7

2nd term 4x^(3)y degree of term = (3 +1) = 4

3rd term 10x² degree of term = 2

So the answer is option A.
The polynomial that is written in standard form is:

-3x^5^2 + 4x^3y + 10x^2

As you can see, the terms are arranged based on the value of the exponents. From the largest exponent x^5 to the smallest exponent x^2.

Describe how you solved the following problem:I have a jar filled with $100 worth of quarters, nickels, and dimes. 

I have the same amount of each type of coin. How many total coins do I have in my jar? 

Answers

first you make sure you have all your variables using same measurement - cents (since it is the smallest)

$100 = 100*100 cents = 100,000 cents
1 quarter = 25 cents
1 nickel = 5 cent
1 dime = 10 cents

the test of your problem said that:
     you have $100     in       i don't know how many coins   of quarters, nickels and dimes
         100,000          =                    X                            *      (25+5+10)


we have to find X:

100,000= X *(25+5+10)
100,000= X *40
X= 100,000/40
X = 2,500 coins

Simplify (3n – 2m)2 = ? a. 6n2 – 12mn – 4m2 b. 9n2 – 12mn – 4m2 c. 9n2 12mn 4m2 d. 9n2 – 12mn 4m2

Answers

If you would like to simplify (3n - 2m)^2, you can do this using the following steps:

(3n - 2m)^2 = 3^2 * n^2 - 3 * 2 * 2 * n * m + 2^2 * m^2 = 9n^2 - 12nm + 4m^2

The correct result would be d. 9n^2 - 12nm + 4m^2. 

Given the formula:  t = (sq. rt. d)/4 what is the value of t when d is 900 minutes?

Answers

t=(√(d))/(4) = (√(900))/(4) = (√(30\cdot 30))/(4) = (30)/(4) = 7.5

How many solutions does this system have? x-2y=2 y=-2+5a. infinitely many solutions
b. no solutions
c. two solutions
d. one solution

Answers

the system has one solution, x = 8, y = 3
In an equation system you'll have:

- System with more questions than equations: infinite solutions
- System with the same number of questions as equations: only one solution with as many answers as questions
- System with two or more independent and contradictory equations: zero solutions.

In this case you have two independent equations and two questions (x and y), so the answer is d, one solution.
