The product of the polynomial is x² - x + xy + 16y - 2y² - 30

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomials are classified based on degree as linear, quadratic, cubic and so on.

Given the polynomial:

(x + 2y - 6)(x - y + 5) = x² + 2xy - 6x - xy - 2y² + 6y + 5x + 10y - 30

= x² - x + xy + 16y - 2y² - 30  

The product of the polynomial is x² - x + xy + 16y - 2y² - 30

Step-by-step explanation:

[tex]2^5 \times 2^{-3}[/tex]

Because the powers have the same base of 2, we can apply the index law:

[tex]a^b \times a^c=a^{b+c}[/tex]

Therefore, [tex]2^5 \times 2^{-3}=2^{5-3}=2^2=4[/tex]

Answer:

When x=0 the friend is 200 miles from the restaurant and at x=5 the friend reaches the restaurant. When x=0 you are 100 miles from the restaurant, so 100 is the y intercept, and when x=5 you reach the restaurant so 5 is the x intercept. We have y=mx+100 and y=0 when x=5, so 0=5m+100 therefore m=-20 and the equation is y=-20x+100.

Answer:

n2=v2n1/v1

Or B

Step-by-step explanation:

P, R, and T are constant, then the volume is directly proportional to the mole. Then the correct option is A.

An ideal gas is a theoretical composed of a set of randomly moving gas particles that interacts only through elastic collision.

Given

A balloon containing 0.040 mol of a gas with a volume of 5.0 mL was expanded to 1.0 L.

[tex] \rm V_1 = 5 \ mL\\ V_2 = 1000 \ mL\\ n_1 = 0.040 \ mol [/tex]

We know the equation of the ideal gas.

[tex] \rm PV = nRT [/tex]

where P, R, and T are the constant, then

[tex] P \propto n[/tex]

Then we have

[tex] \rm \dfrac{V_2}{V_1} = \dfrac{n_2}{n_1} \\\\ V_2 = n_2 *\dfrac{V_1}{n_1} [/tex]

Thus, the correct option is A.

Answer:

D) [tex]f(x)=8x^5+7x^3-5x[/tex]

Step-by-step explanation:

A function is odd if its graph is symmetric to the origin, which we can check this if [tex]f(-x)=-f(x)[/tex] is true:

Option A

[tex]f(x)=7x^4+13x^3-11\\\\f(-x)=7(-x)^4+13(-x)^3-11\\\\f(-x)=7x^4-13x^3-11[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option B

[tex]f(x)=5x^7+4x^6+3x^5+x\\\\f(-x)=5(-x)^7+4(-x)^6+3(-x)^5+x\\\\f(-x)=-5x^7+4x^6-3x^5+x[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option C

[tex]f(x)=13x^5-\frac{1}{2}x^3+7x+3\\\\f(-x)=13(-x)^5-\frac{1}{2}(-x)^4+7(-x)+3\\ \\f(-x)=-13x^5-\frac{1}{2}x^4-7x+3[/tex]

Since [tex]f(-x)\neq-f(x)[/tex], then the function does not have odd symmetry

Option D

[tex]f(x)=8x^5+7x^3-5x\\\\f(-x)=8(-x)^5+7(-x)^3-5(-x)\\\\f(-x)=-8x^5-7x^3+5x[/tex]

Since [tex]f(-x)=-f(x)[/tex], then the function DOES have odd symmetry. You can also see that the function is odd because every term has an odd exponent.

17 is what percent of 68?

Its 25%

17/68*100

= (17*100)/68

= 1700/68 = 25

Answer:

25%

Step-by-step explanation:

Question : 17 is what percent of 68?​

Answer :

To solve this let the unknown percentage be x .

Let us solve now.

68 × x% = 17

68 × [tex]\frac{x}{100}[/tex] = 17

And now let us find the percentage by making x as the subject.

[tex]x=\frac{17*100}{68}[/tex]

[tex]x = \frac{1700}{68}[/tex]

[tex]x =25[/tex]

Therefore, the percentage is 25%

Direct proportion: If a variable increases then other variable also increases with a constant factor  i.e.  y = kx

Inverse proportion:  if a variable increases then other variable decreases with a  constant factor  i.e   xy = k

Assume that food will last for d days if 20 more persons join the camp.

Understand the fact that for given food number of days food last is inversely proportional to the number of persons hence product of days food lasts and number of persons is constant,

Days x number of persons = constant

Equate the product of 300 persons and 42 days  with (300 + 20) person and d days to solve for d.

[tex](300+20) *d=300*42[/tex]

⇒ [tex]d = \frac{12600}{320}[/tex]

⇒ [tex]d =\frac{1260}{32}[/tex]

⇒ [tex]d=\frac{315}{8}[/tex]

⇒ [tex]d=39.375[/tex] [tex]days[/tex] [tex]or[/tex] [tex]39(\frac{3}{8} )days[/tex] [tex]in[/tex] [tex]fraction[/tex]

Hence, if 20 more people Join (320 people ) it will last 39.375 days in decimal or 39 3/8 days in fraction
