Select which equations are POLYNOMIALS and which are NOT POLYNOMIALS.
hammer [34]
In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
<span>a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1

Not polynomials are:
</span><span>c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) </span>|x|^2+4√x-2=<span>|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2</span>

Ms.Miller decides to give a test worth 120 points and contains 36 questions. Multiple-choice questions are worth 3 points and op
wariber [46]

The number of multiple-choice questions is 30.

The number of open-response questions is 6.

<h3>What is an equation?</h3>

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

Number of multiple choice questions = M

Number of open response questions = N

We can make two equations.

M + N = 36 _______(1)

3M + 5N = 120 ______(2)

From (1) we get,

M = 36 - N ______(3)

Putting (3) in (2) we get,

3(36 - N) + 5N = 120

108 - 3N + 5N = 120

2N = 120 - 108

2N = 12

N = 6

Now,

Putting N = 6 in (3) we get,

M = 36 - 6

M = 30

Thus,

The number of multiple-choice questions and open-response questions is 30 and 6.

The length of a rectangle is 4 units greater than its with ,and the area of a rectangle can be expressed by the equation y= x^2+
anyanavicka [17]

Answer:

all real numbers

Step-by-step explanation:

The domain are the values of the input values x that makes the given function exist

Given the function:

y= x^2+4x

Since x^2 is a perfect square, the value of x can exist on all real numbers

Hence the domain of the function is all real numbers

The half-life of a particular element is 10 days. If you begin with 40 grams of the element write an exponential decay function
galben [10]

Answer:2.25 grams

Step-by-step explanation:

To find the remaining mass of an element, apply the following:

m0 = m/(2^n), where m0 is the remaining mass, m as the original mass and n as the number of half lives that have passed.

we have m, we just have to find n. To find n,

24/6 = 4 half lives have passed.

Applying the first formula,

m0 = (36)/(2^4) = 36/8 = 2.25 grams

Hope this helps, brainliest would be appreciated :)
