The function N(t)=300/(1+299e^-0.36t) describes the spread of a rumor among a group of people who have heard the rumor, and (t)

Delvig [45]

A ) The rate at which rumor spreads speed up over time. If t increases, also N(t) increases, because 300 is divided by the smaller number.( Correct )B ) 1 = 300 / ( 1 + 299 · e^(-0.36 · 0 ) ) 1 = 300 / ( 1 + 299 · 1 ) 1 = 300 / 3001 = 1 ( Correct )C ) 100 = 300 / ( 1 + 299 · e^(-0.36 · 14 ) )100 = 300 / ( 1 + 299 · 1/154.47 )100 = 300 / 2.93565100 ≈ 102.192 ( Correct ) - approx. 14 minutes
D ) N = 300 / ( 1 + 299 · e^(-∞) )N = 300 / ( 1 + 299 · 0 ) N = 300 / 1 = 300299 people are enclosed space ( Not correct )Answer:True statements are: A ) , B ) and C ) .

Why does dividing 5 by a decimal less than 1 give a quotient greater than 5

goldenfox [79]

5 x 0.2 = 25

Or to put it a different way

25 / 0.2 = 5

Dividing something by a number greater than 1 gives you a smaller number
Dividing something by 1 gives the same number
Dividing something a number smaller than 1 gives you a larger number

The value of a certain rare stamp is 160% of its value three years ago if the stamp is worth $220 then what is it’s worth today

xz_007 [3.2K]

Answer:

572$

Step-by-step explanation:

100% of 220 is 220 so add them together. Then find 60 % of 220. To find 10% of a number move the decimal to the left one time. Which is 22. After that, multiply 22 by 6 because it's 60%. then ad 220+220+132=572.

elect the correct answer from each drop-down menu. A system of linear equations is given by the tables. x y -5 10 -1 2 0 0 11 -2

sergeinik [125]

Answer:

First equation: y = -2x

Second equation: y = 3 - x

Solution: (1, -2)

Step-by-step explanation:

Assuming the ordered pairs of the tables are:

Table 1

(-5, 10) (-1, 2) (0, 0) (11, -22)

Table 2

(-8, -11) (-2, -5) (1, -2) (7, 4)

To create a linear equation, pick 2 ordered pairs. Calculate the slope by using the slope formula, then use the points-slope form of the linear equation to form the equation.

$\textsf{slope }m=\dfrac{\textsf{change in }y}{\textsf{change in }x}$
