The Answer Is:<span>4.222222</span>

4 2/9 = 4 + 2/9

= 4/1 + 2/9

= (4/1 * 9/9) + 2/9

= 36/9 + 2/9

= 38/9

= 38 ÷ 9 = 4.222222

Karen had 15 snicker bars. she gave 7 to her brother. what percent did she give away
Mekhanik [1.2K]

Step-by-step explanation:

The way to get this is that you put them in fraction form 7/15 and then you make it equal to to x/100 and then divide the known part of the fraction which in this case is 100/15 which gives 6.67 (rounded). After you get that you multiply it by 7 which give you 46.69%

Find the x and y intercepts of the following function.<br> g(x)=x^2-5x-84
Ahat [919]

Answer:

see explanation

Step-by-step explanation:

To find the y- intercept let x = 0 in the function

g(0) = 0 - 0 - 84 = - 84 ← y- intercept

To find the x- intercepts let y = 0, that is

x² - 5x - 84 = 0

To factor the quadratic

Consider the factors of the constant term (- 84) which sum to give the coefficient of the x- term

The factors are - 12 and + 7, since

- 12 × 7 = - 84 and - 12 + 7 = - 5, thus

(x - 12)(x + 7) = 0

Equate each factor to zero and solve for x

x - 12 = 0 ⇒ x = 12

x + 7 = 0 ⇒ x = - 7

x- intercepts are x = - 7 and x = 12

Which of the following polynomials has an even degree and a negative leading coefficient?
spin [16.1K]

Using limits, the polynomial that has an even degree and a negative leading coefficient is:

Polynomial going down from the left and passing through the point negative 7 comma 0 and going to a local minimum and then going up through the point negative 3 comma 0 and 0 comma 8 to a local maximum and then down to the right through the point 4 comma 0.

<h3>What is a limit?</h3>

A limit is given by the value of function f(x) as x tends to a value.

In this problem, to find the polynomial, we have to find the limits as x goes to infinity, hence:

\lim_{x \rightarrow -\infty} f(x) = [tex]\lim_{x \rightarrow -\infty} -a x^n

Since n is even, we have that:

  • \lim_{x \rightarrow -\infty} -a (-\infty)^n = -a \times \infty = -\infty
  • \lim_{x \rightarrow \infty} -a (\infty)^n = -a \times \infty = -\infty

Since it goes down to the left and down to the right, hence the function is:

Polynomial going down from the left and passing through the point negative 7 comma 0 and going to a local minimum and then going up through the point negative 3 comma 0 and 0 comma 8 to a local maximum and then down to the right through the point 4 comma 0.
