Determine if the expression x is a polynomial or not. If it is a
polynomial, state the type and degree of the polynomial.

Answers

Answer 1

9514 1404 393

Answer:

  x is a polynomial of degree 1

Step-by-step explanation:

"x" is an expression in one variable. The degree of the variable is 1, which is a non-negative integer. So, the expression "x" is a polynomial of degree 1. Because this polynomial has only one term, it is called a monomial. Because the degree is 1, it is a linear polynomial.

The square root of 105 would lie between which two consecutive integers?

Answers

Answer:

the square root of 105 lies between 10 and 11

Step-by-step explanation:

Which perfect squares "box" 105 in?  10^2 = 100 and 11^2 = 121.

The square roots of 100 and 121 are 10 and 11.  

Thus, the square root of 105 lies between 10 and 11.

-20x^2 + 56x - 15

Step-by-step explanation:

3x(−2+7)−5(x−1)(4x−3)

Add −2 and 7 to get 5.

3x×5−5(x−1)(4x−3)

Multiply 3 and 5 to get 15.

15x−5(x−1)(4x−3)

Use the distributive property to multiply −5 by x−1.

15x+(−5x+5)(4x−3)

Apply the distributive property by multiplying each term of −5x+5 by each term of 4x−3.

15x−20x^2+15x+20x−15

Combine 15x and 20x to get 35x.

15x−20x^2+35x−15

Combine 15x and 35x to get 50x.

If using the method of completing the square to solve the quadratic
equation x2 + 5x – 1= 0, which number would have to be added to "complete the square"?

Answers

Answer:

25/4 or 6.25

Step-by-step explanation:

Given that the general equation of  a quadratic equation is given as ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.Hence given x^2-5x-19=0, to complete the square, we add (-5/2)^2 to both sides following the illustration given.This is 25/4 or 6.24

The function Mx)=x^3-3x^2+ 2x rises as x grows very small.
A. True
O B. False

Answers

It’ll be false

The phrasing "x grows very small" is the same as saying "x gets more negative". So it starts off with x = -1, then goes to x = -2, then to x = -3, etc etc
Visually x is moving to the left
As you move to the left along this curve, you'll eventually go downhill at some point and keep going downhill. So overall, y is getting more negative as well. This means the function is falling as you move to the left.
----------
We can see this numerically. If x = 0, then y = 0 after plugging it into y = x^3-3x^2+2x
Then plug x = -1 into that same equation and you should get y = -6
Plug x = -2 into that equation and you should get y = -24
The progression from y = 0 to y = -6 to y = -24 shows y getting more larger in the negative direction.

A right triangle has a hypotenuse of 10 feet and a leg of 6 feet. What is the length of the other leg?

Answers

Answer:

The other length of the leg is 8 feet.

Step-by-step explanation:

To find the answer we have to find what 10 and 6 is squared.  10 x 10 = 100.  

6 x 6 = 36.  Now since we are trying to find the length of the other leg, we will subtract 100 from 36 and we get 64.  Then for the last step, we will figure out what number squared equals 64.  Because 8 x 8 = 64, 8 is our answer.

A square has a diagonal with the length of 8V7 inches. What is the length of the
sides?

Answers

Answer:

approximately 13.9 inches

Step-by-step explanation:

That's 8√6, not 8V7.

The four sides are of the same length (x).  According to the Pythagorean Theorem, x² + x² = (diagonal length)² = (8√6)², or

2x² = 64(6) = 384

Dividing both sides by 2, we get:

x² = 192, or x² = 4(48).  Then the side length is x = √16√12, or

x = 4√4√3 = 8√3.  This is approximately 13.9 inches.
