Step-by-step explanation:

12=9

1=x

(cross multiply

12x=9

divide both sidesby 12

12x/12= 9\12

x= o.75

approximately 1

sveticcg [70]

a) (x+6)^2-25

b) (-6, -25)

Step-by-step explanation:

Perfect square trinomial! If you have 12x, divide by two and get 6, so we have (x+6)^2+q. Then solve for q. You get q as -25.

For b, we just take the vertex from vertex form. We get x+6=0 so x=-6, and q = -25, so the answer is (-6, -25).

Hope that helped,

three apples and four bananas cost $4.85 . three apples and ten bananas cost $8.75.Find the cost of an apple.
konstantin123 [22]
8.75-4.85= 3.90= cost of 6 bananas
3.9/6=0.65= cost of one banana
.65*4=2.60= cost of 4 bananas
4.85-2.60= 2.25= cost of 3 apples
2.25/3=.75= cost of an apple

We are given a boxplot that contains some data. We will use the information below to analyze the given question.

STEP 1: Median

From the image above, we can see that the median represents the line drawn inside the box

This gives;

\text{Median}=24

STEP 2: Interquartile range

The interquartile range is the difference between the third quartile and the first quartile.

\begin{gathered} q_3=28 \\ q_1=22 \\ \text{IQR}=28-22 \\ \text{IQR}=6 \end{gathered}

In an ellipse, the ratio of the distance between the foci and the length of the major axis is called:
Anni [7]

The ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity.

<h3>Definitions of dimensions in ellipses</h3>

Dimensionally speaking, an ellipse is characterized by three variables:

  1. Length of the <em>major</em> semiaxis (a).
  2. Length of the <em>minor</em> semiaxis (b).
  3. Distance between the foci and the center of the ellipse (c).

And there is the following relationship:

c = \sqrt{a^{2}-b^{2}} (1)

Another variable that measure how "similar" is an ellipse to a circle is the eccentricity (e), which is defined by the following formula:

e = \frac{c}{a}, 0 \ge c \ge 1 (2)

The greater the eccentricity, the more similar the ellipse to a circle.

Therefore, the ratio of the distance between the foci and the length of the <em>major</em> axis is called eccentricity. \blacksquare
