A population of paramecia, P, can be modeled using the exponential

Mathematics
1 answer:
Ksivusya [100]2 years ago
4 0

The appropriate domain of the population function is 0 ≤ t ≤ 14

<h3>How to determine the domain?</h3>

The function is given as:

P(t) = 3(2)^t

From the question, we understand that the maximum time is 2 weeks.

2 weeks in days is 14 days

This means that the function is valid for 14 days i.e. t = 0 to 14

Hence, the appropriate domain of the population function is 0 ≤ t ≤ 14

A scatter plot was constructed and a line of best fit was drawn, 25x 80. What is the equation of this best line of fit?
Tcecarenko [31]

Answer:

y = 5x + 25

Explaination:

To get the equation of a line, first get the slope of the line.


Slope = (change in y)/(change in x)


          = (60-30)/(7-1)


          = 30/6


            = 5


Now use one point in the line (4,45) and a general point (x,y).


Slope = (change in y)/(change in x)


    5 = (y - 45)/(x - 4)


    5(x - 4) = (y - 45)


  5x - 20 = y - 45


y = 5x -20 + 45

1. PLEASE HELP. Consider the matrices-
Alex

Answer:

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Step-by-step explanation:

Since Matrix A and Matrix B have the same size, then we can simply perform the operation of subtraction on each position within the matrices to get the resulting subtracted matrix.

A =  [  4  7  ]              B =  [  5  4  ]

      [ -3  8  ]                     [  3  6  ]

      [ -5 -2  ]                    [  -1  8  ]

A - B  =  [ (4 - 5)  (7 - 4) ]

             [ (-3 - 3) (8 - 6) ]

             [ (-5 - -1) (-2 - 8) ]

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Cheers.
