Given the functions j(x) = x2 + 3 and k(x) = x2 − x + 4, which operation results in a 2nd degree polynomial?

GrogVix [38]

Addition is the correct answer.

x^2 is the part where you get the second degree term. If you add x^2+x^2 you get 2x^2. If you subtract x^2-x^2 you get 0. If you multiply x^2*x^2 you get x^4, which is a fourth degree term

Solve the following quadratic equation.

Nonamiya [84]

Given:

Consider the given equation is

$(x-18)^2=1$

To find:

The values of x.

Solution:

We have,

$(x-18)^2=1$

Taking square root on both sides, we get

$x-18=\pm\sqrt{1}$

$x-18=\pm 1$

Adding 18 on both sides, we get

$x-18+18=\pm 1+18$

$x=\pm 1+18$

Now,

$x=1+18$ and $x=-1+18$

$x=19$ and $x=17$

Therefore, the correct option is A.

Which of the following best describes an irrational number?

Furkat [3]

Answer:

Option D is correct.

D- A number that cannot be expressed as a fraction, , where p and q are integers

Step-by-step explanation:

Irrational number:

An irrational number can not be expressed as a fraction or ratio of integers, like $\frac{p}{q}$ where p and q are integers

And also it can not be expressed as terminating decimal or repeating decimal

Example of the irrational number is given below.

$\sqrt{8}= 2.82842$

$\pi = 3.14285..$

$\sqrt{3}= 2.82842$

Therefore option D (A number that cannot be expressed as a fraction, , where p and q are integers) is correct .

Let y = safe load in pounds and x = length in feet of a horizontal beam. A constant of proportionality k exists such that y=k/x

Contact [7]

Answer:

Option c. 30,000

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

y ----> safe load in pounds

x ----> length in feet of a horizontal beam

we have

For $x=15\ feet, y=2,000\ pounds$

Remember that

$k=y*x$

substitute

$k=2,000*15=30,000$
