Is the function f(x) = 1 /x− 1 continuous at x = 1? Explain.

Answers

Answer 1

Faarax Mohammed shirwa search

Answer 2

Answer:

no

Step-by-step explanation:

f(x) = [tex]\frac{1}{x-1}[/tex]

at x = 1

f(1) = [tex]\frac{1}{1-1}[/tex] = [tex]\frac{1}{0}[/tex]

division by zero is undefined, thus there is a discontinuity at x = 1

so f(x) is not continuous at x = 1

Despite control measures, the pigeon population in Winchester is increasing by 10% each year. If there are currently 9,520 pigeons, how many pigeons will there be in 13 years?
If necessary, round your answer to the nearest whole number.

Answers

Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.

What is an exponential function?

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

The initial value and the growth rate are given by:

A(0) = 9520, r = 0.1.

Hence the function is given by:

[tex]A(t) = 9520(1.1)^t[/tex]

Hence in 13 years, the amount of pigeons will be of:

Solve the inequality for x and identify the graph of its solution (picture added)

Answers

The inequality that is correctly graphed is the one in option B.

Which graph correctly describes the inequality?

Remember that if we have symbols like ≤ or ≥, we graph a solid circle, while if we use symbols like > or <, we need to use an open circle.

If we write:

x < -3

Then we must have an orange line to the left of x < -3

Finally, the option that you marked is wrong.

Why?

There it says that:

"x < -3 and x > 1"

The "and" means that x meets both properties at the same time, which is impossible.

The correct option is the one that says:

"x < -3 or x > 1".

The "or" means that x needs to meet only one of the two conditions, not both at the same time.

the area of the triangle below is 1/4 square meters. what is the length of the base. express your answer in simplest form

Answers

Answer:

4/5

Step-by-step explanation:

Given,

Area of the triangle = 1/4 square meters

From the diagram,

Height = 2/5 m

To find : Length of the base

Formula : -

A = bh/2

Here,

A denotes Area

b denotes Base

h denotes Height

A = 1/4

h = 2/5

A = bh/2

Cross multiply,

A * 2 = bh

2A = bh

2 * (1/4) = b * (2/5)

(1 * 2)/4 = (b * 2)/5

2/4 = 2b/5

1/2 = 2b/5

Cross multiply,

1 * 5 = 2 * 2b

5 = 4b

b = 4/5 meters

Hence,

The length of the base is 4/5 meters.

The length of the base of the triangle is 5/4 meters.

What is Triangle?

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

The formula to find the area of the triangle is,

Area = [tex]\frac{1}{2}[/tex] × base × height

Given,

Area of the given triangle = 1/4 square meters

Height = 2/5 meters

Substituting in to the formula,

[tex]\frac{1}{2}[/tex] × base × 2/5 = 1/4

1/5 × base = 1/4

Base = 5/4 meters

Hence the base of the triangle is 5/4 meters.

The answer is -1 because x=8/3 and x also =-1

Answer:

x = -1 or x = 8/3

Step-by-step explanation:

3x² - 8 = 5x

3x² - 5x - 8 = 0

3x² - 8x + 3x - 8 = 0

(Here you find two numbers which have a sum of        -5 and a product of 3×-8= -24. These two numbers are -8 and 3. -8 + 3 = -5 and -8 × 3 = -24.)

(3x² - 8x) (3x - 8) = 0

x(3x - 8) +1(3x - 8) = 0

(x + 1) (3x - 8) = 0

x + 1 = 0     OR      3x - 8 = 0

x = -1                      3x = 8

The probability that the ball we remove at the 11th round is blue will be 0.6.

How to calculate probability?

From the information given, we remove a random ball and replace it with a new red ball. for example, after the first round we have 9 blue balls and one red ball.

Since we have 9 blue balls and remove one every round. Let's assume that the number of blue and red balls will be 6 and 4 respectively in the 11 the round

Therefore, the probability that the ball we remove at the 11th round is blue will be:

= 6/(6 + 4)

mode: this is the heighest occuring number or the number with the heighest frequency.

mean: this is the average number. it's obtained by adding the data values in a set of numbers and dividing the sum by the number of data items.

meadian: this is the middle number when the data is ordered or when the data is arranged in ascending or descending order.

from the data,

mode: no number occured more than the other. therefore, there is no mode
