Answer:

D. Their addiction to nicotine.

Explanation:

Nicotine is a type of drug which makes it tough for smokers to stop smoking and this is what makes them attracted most. The more nicotine you inhale, the better you feel - giving pleasure. Nicotine is harmful for the body and increases possibility of heart attack.

All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The function given in the problem is,

[tex]f(x)=x^3+3x^2-x-3[/tex]

If f(1) = 0

[tex]f(1)=(1)^3+3(1)^2-(1)-3\\f(1)=1+3-1-3\\f(1)=0[/tex]

Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'

[tex]x^3+3x^2-x-3=0\\x^2(x+3)-1(x+3)=0\\(x+3)(x^2-1)\\(x+3)(x+1)(x-1)=0[/tex]

Equate all the groups to zero to find the roots as,

[tex]x+3=0, x=-3\\x+1=0, x=-1\\x-1=0, x=1[/tex]

Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

Im not completely sure what this question is asking, however I'll try...

Well, if the length is in feet and the width is in feet, that would conclude that the perimeter would also be in feet. If you're asking for the actual number answer for what the perimeter is, I will not be able to help since there is a lack of information; you can only determine the perimeter when given the exact number of feet, both the width and length are.

Hi!

Given:

The first equation we can make can use the total number of tickets. The total number of tickets would be equal to the number of student tickets plus the number of adult tickets, correct? Therefore:

[tex]x+y=2400[/tex]

Now, the second one can use the profit and the price of each ticket. The number of student tickets multiplied by 3 (for the price) plus the number of adult tickets multiplied by 5 would be equal to the total profit. Hence:

[tex]3x+5y=9000[/tex]

Therefore, your system of equations is:

[tex]x+y=2400[/tex]

[tex]3x+5y=9000[/tex]

Answer:

Step-by-step explanation:

To factor out a GCF from a polynomial we first need to identify the GCF of all the terms, this is the part that goes in front of the parenthesis, then we divide each term by the GCF, the answer is what is left inside the parenthesis. This is shown in the following examples Example 3. 4x2−20x+16 4x2 −20x16GCF is4, divide each term by4

Step-by-step explanation:

since the polynomial is in the form

+x² - nx - m

we know that we are looking for 2 factors of x (to create x²).

and they must be in the form of

(x + a)(x - b)

to create the negative "m" at the end.

and "b" must be larger than "a" to create the negative "n" in the middle.

let's do the multiplication and compare the parts with our actual expression :

(x + a)(x - b) = x² - bx + ax - ab = x² + (a - b)x - ab

so, we know now in numbers that

-ab = -44

ab = 44

and

a - b = -7

a = b - 7

the short solution here is trial and error with the factors of 44 :

44 = 1×44 = 2×22 = 4×11

ah, only one combination has a difference of the factors of 7 or -7 : 4 and 11.

since b has to be larger (as a - b = -7), we have a = 4 and b = 11

and the factorization of our original expression is

f(x) = (x + 4)(x - 11)

FYI

if there is not such a short list of options to try, we can also go the full formal way :

we can use the second equation as identity in the first equation and get

(b - 7)b = 44

b² - 7b = 44

b² - 7b - 44 = 0

by the way, it is not surprising that it looks the same way as the original expression in x, because the factorization uses exactly the zero solutions for the original expression.

anyway, the formal solution to a quadratic equation of

ax² + bx + c = 0 is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = b (the variable of our equation above)

a = 1

b = -7

c = -44

b = (7 ± sqrt((-7)² - 4×1×-44))/(2×1) =

= (7 ± sqrt(49 + 176))/2 = (7 ± sqrt(225))/2 =

= (7 ± 15)/2

b1 = (7 + 15) / 2 = 22/2 = 11

b2 = (7 - 15) / 2 = 8/2 = 4

based again on the original equations and the fact that b has to be the larger number, we get again (of course) that b1 is the valid solution and

b = 11 and a = 4

Step-by-step explanation:

price of gas last week= $2.25

15% of $2.25 = 15/100 × 2.25

= $0.3375

since the price of the gas decreased by 15% this week, the new price will be 2.25- 0.3373 =$1.9125.
