In 2004, a magazine's circulation was about 1,000,000 readers. In 2014, the magazine had about 2,000,000 readers. Write a linear
Sever21 [200]

Answer:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000

Step-by-step explanation:

For this case we want to find a linear model given by:

r =mt+b

Where r = represent the number of readers , t= years after 2000

m = the slope for the model and b the intercept

For this case we can define the following points from the data given:

(t_1, r_1) = (4, 1000000) 4 years after 2000

(t_2, r_2) = (14, 2000000) 14 years after 2000

We can find the slope with the following formula:

m= \frac{r_2 -r_1}{t_2 -t_1}= \frac{2000000-1000000}{14-4}=100000

And then we can use for example the first point (t_1, r_1) = (4, 1000000) to find the intercept:

1000000= 100000*4 + b

b=600000

So then the linear model for this case should be:

r = 100000 t + 600000

Seven less than negative two times a number is greater than or equal to 41
kotegsom [21]

Solution, -2n-7\ge \:41\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-24\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-24]\end{bmatrix}

Steps:

\mathrm{Add\:}7\mathrm{\:to\:both\:sides}, -2n-7+7\ge \:41+7

\mathrm{Simplify}, -2n\ge \:48\\\\

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}, \left(-2n\right)\left(-1\right)\le \:48\left(-1\right)

\mathrm{Simplify}, 2n\le \:-48

\mathrm{Divide\:both\:sides\:by\:}2, \frac{2n}{2}\le \frac{-48}{2}

\mathrm{Simplify}, n\le \:-24

The correct answer is n\le \:-24

I hope this helps!!!

What information do you need to know to calculate last year’s winning speed? Remember, the distance traveled (length of the cour
Andrews [41]

Answer:

1. Total distance

2. Shortest time taken

Step-by-step explanation:

Since it is a competition the distance will be the same for all participants.

therefore the information need is

1.  The total distance of the competition

2. The time taken by each participant to complete the race

The winning speed is the speed is given as the distance covered in the shortest possible time.

hence the winning speed is expressed as

winning speed= distance/short time taken
