The linear function to model this problem is y = 2.50x + 5

A linear function is a type of mathematical function that describes a straight line. A linear function is defined by an equation of the form:

y = mx + c

Where y is the dependent variable (the variable being measured or predicted), x is the independent variable (the variable being used to make the prediction or explanation), m is the slope of the line (the rate of change of y with respect to x), and c is the y-intercept (the value of y when x is zero).

The linear function to model this problem is given as;

y = 2.50x + 5

We can use a graphing calculator to represent this.

Therefore, company A will charge less than company B for any mileage greater than 65 miles.
To help you with your question, I need the specific prices for both companies, as well as any additional information you can provide about the charges.

To solve for the mileages at which company A will charge less than company B, we can set up the following inequality:
A < B
where A is the cost of renting from company A and B is the cost of renting from company B. We can plug in the given information to get:
x ≤ A
x > B = y + 40z
where x is the number of miles driven, y is the initial fee for company B, and z is the additional cost per mile for company B.
Now we can substitute the given values to get:
x ≤ A
x > y + 40z
For company A, the cost is a flat rate with unlimited mileage, so A is just the cost listed for one day of rental. Let's say that cost is $100.
For company B, the initial fee is $50 and the additional cost per mile is $0.25. So:
y = 50
z = 0.25
Now we can plug in these values and solve for x:
x ≤ 100
x > 50 + 40(0.25)
x > 65
Therefore, company A will charge less than company B for any mileage greater than 65 miles.
To help you with your question, I need the specific prices for both companies, as well as any additional information you can provide about the charges.

There is no such a number whose absolute value is -2. This is because the absolute value of any number is its distance from 0 irrespective of the direction.

An absolute value of a number is the distance of the number from 0 on a number line irrespective of the direction.

Consider the number "x".

Then its absolute value is written as

|x| = x if x ≥ 0;

   = 0 if x = 0;

   = -x if x < 0;

For example x = -9; then its absolute value is

|(-9)| = -(-9) = 9; (Since x = -9 < 0; we applied |x| = -x)

So, we can conclude that irrespective of the direction (positive or negative), the absolute value of any number remains positive.

We know that the absolute value of any number is calculated by

|x| = x if x ≥ 0;

   = 0 if x = 0;

   = -x if x < 0;

And the absolute value of any number irrespective of its direction on the number line remains positive.

So, no such number has a negative absolute value.

Hence, the answer is none for the given question.

This scenario describes a foodborne illness outbreak investigation, where several individuals with similar symptoms of food poisoning have been identified and traced back to a nearby restaurant.

In this situation, the local hospital has encountered multiple cases of individuals exhibiting symptoms consistent with food poisoning. Through interviews, it is discovered that all of them have recently dined at a nearby restaurant, indicating a potential common source of exposure. To further investigate and identify the cause of the illness outbreak, samples from the restaurant's food are collected.

These samples will undergo laboratory testing to check for the presence of pathogens, such as bacteria or viruses, that may be responsible for the foodborne illness. By analyzing the test results, health authorities can pinpoint the specific pathogen and take appropriate measures to prevent further spread and ensure the safety of the community.

The distance between the given points a (5, 3) and b (7, -4) is `sqrt[53]` or approximately 7.28 units.

To find the distance between the given points a (5, 3) and b (7, -4),

we can use the distance formula.

Distance formula: The distance formula is used to find the distance between two points in a plane.

It is given by;`d = sqrt[(x2 - x1)² + (y2 - y1)²]`

where, (x1, y1) and (x2, y2) are the coordinates of two points on a plane,

and d is the distance between the two points.

So, for points a (5, 3) and b (7, -4), let's substitute the values in the formula;

d = sqrt[(7 - 5)² + (-4 - 3)²]d = sqrt[2² + (-7)²]d = sqrt[4 + 49]d = sqrt[53]

Hence, the distance between the given points a (5, 3) and b (7, -4) is `sqrt[53]` or approximately 7.28 units.

if x=1

f(1)=1250(0.8)^1=1000 $

if x=2

if x=3

f(3)=1250(0.8)^3=640  $

so D is the correct answer.

The radius of the wheel 0.35m

The number of revolutions is 100

The distance is 220 meter

Distance in one revolution= 220/100

Answer:

An equation for the nth term is aₙ = 2ⁿ⁻¹

and a₁₀ = 512

Step-by-step explanation:

From the question, 1 cell divides and becomes 2 cells, those 2 cells divide and become 4 cells, and so on

∴The sequence will be

1,2,4, ..., n

From the formula

aₙ = a₁rⁿ⁻¹

Where aₙ is the nth term

a₁ is the first term

n is the number of terms

and r is the common ratio

From the sequence,

a₁ = 1,

r = a₂/a₁ = 2/1 = 2

∴ The nth term (aₙ) will be

aₙ = (1)(2)ⁿ⁻¹

aₙ = 2ⁿ⁻¹

Hence, an equation for the nth term is aₙ = 2ⁿ⁻¹

To find a₁₀, substitute n= 10 into the equation

aₙ = 2ⁿ⁻¹

Then

a₁₀ = 2¹⁰ ⁻ ¹

a₁₀ = 2⁹

a₁₀ = 512

∴ a₁₀ = 512

There are 2,520 ways to form a committee consisting of 3 men and 5 women from a group of 5 men and 10 women.

The combination formula gives the number of possibilities to choose a committee of three persons from a group of five:

Also, the number of ways to select a committee of 5 women from 10 women is given by:

C(10, 5) = 10! / (5! * 5!) = 252

The total number of ways to select a committee consisting of 3 men and 5 women: 10 * 252 = 2,520

To find the partial derivative with respect to x, we need to treat y as a constant and differentiate with respect to x. Using the chain rule, we get:

∂z/∂x = 6(x^3 + x - y)^5 (3x^2 + 1)

To find the partial derivative with respect to y, we need to treat x as a constant and differentiate with respect to y. Using the chain rule again, we get:

The sum of the infinite geometric series –288 –216 –144 –72 is -1152.

The sum of an infinite number of terms having a constant ratio between successive terms is called as infinite geometric series.

Given series, -288, -216, -144, -72, ...

The sum of the infinite geometric series can be calculated as:

Sum = \(\dfrac{a}{1 -r}\)

Here, 'a' is the first term of the series and 'r' is the common ratio.

a = -288

The common difference can be calculated as:

r = \(\dfrac{(-216)}{(-288)}\)

= \(\dfrac{3}{4}\)

Substitute the values in the sum formula:

Sum = \(\dfrac{-288}{1 - \dfrac{3}{4}}\)

It can be simplified as:

Sum =  -288 \(\times\) 4

             = -1152
