1) function f(x)

              x - 5
f(x) = ----------------
          3x^2 - 17x - 28

2) factor the denominator:

3x^2 - 17x - 28 = (3x + 4)(x - 7)

                        x - 5
=> f(x) = -----------------------
                (3x + 4) (x - 7)

3) Find the limits when x → - 4/3 and when x → 7

Lim of f(x) when x → - 4/3 = +/- ∞

=> vertical assymptote x = - 4/3

Lim of f(x) when x → 7 = +/- ∞

=> vertical assymptote x = 7

Answer: there are assympotes at x = 7 and x = - 4/3

Ierofanga [76]

Answer:

The answer is "12 inches".

Step-by-step explanation:

Please find the image file of the graph.

We know $AE = CF \ and \ EB = FB$ so because the triangle is isosceles.

$EB = 2x, FB = 2x,\ and \ CF = x$ when $AE$ is called by $x$ .

We know that $AE = AD = x$ since E and D are tangent points to a circle.

They have $CD = CF = x$ since D and F are tangent points only to circle.

Thus, if the perimeter is 32, the following is the result:

$\to AE + EB + BF + FC + CD + DA = 32\\\\\to x + 2x + 2x + x + x + x = 32\\\\\to 8x = 32\\\\\to x = 4$

Therefore the length of $BC = BF + FC = 2x + x = 3x = 12\ inches$

Find X. please i need help with this

-BARSIC- [3]

Answer:

Step-by-step explanation:

X + X + 96 = 180 {SUM OF ANGLES OF TRIANGLE}

2X + 96 = 180

2X = 180 -96

2X =84

X = 84/2

X = 42

CHAPTER 1: INTRODUCTION

1.1 The Basics

Definition: statistics

Statistics is the science of collecting, organizing, interpreting, and learning from data.

COURSE GOAL:

Learn how to use statistical methods to translate data into knowledge so that we can investigate

questions in an objective manner. Here are some examples of questions we’ll have the tools to

answer before the end of the semester:

1. How can we estimate the percentage of American citizens who would vote for Hillary Clinton

if the presidential election were held today? How certain are we about our estimate?

2. What is the relationship between the amount of time spent studying and the score received

on an exam?

3. Is there an association between smoking and divorce? If so, does that mean smoking causes

divorce?

THREE ASPECTS OF STATISTICS

1. Design: Planning how to obtain data to answer the question of interest.

2. Description: Summarizing the data that are obtained.

3. Inference: Using sample data to learn about the population: make decisions and

predictions based on the data for answeri
