The table shows the estimated number of bees, y, in a hive x days after a pesticide is released near the hive. Which function be

vladimir2022 [97]

Answer:

The exponential function best models the data for the given table.

Step-by-step explanation:

Given : The table showing the estimated number of bees, y, in a hive x days after a pesticide is released near the hive.

We have to find which function best models the data for the given table.

Consider the given data in the table.

We first plot the data using Expo- regression calculator (as shown in attachment)

Since, The the estimate number of bees deceases with increasing number of days ,thus the data represents an exponential decay over time.

Thus, The exponential function best models the data for the given table.

And the equation of model is given as $y=9958.3e^{-0.029x}$

Where y represents the estimate number of bees

and x represents the number of days.

Find the distance between the points<br><br> (1,8) and (-3,8)

Vilka [71]

Answer:

<h2>4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

From the question we have

$d = \sqrt{ {(1 - - 3)}^{2} + ({8 - 8})^{2} } \\ = \sqrt{ ({1 + 3})^{2} } \\ = \sqrt{ {4}^{2} } \: \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{16} \: \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

<h3>4 units</h3>

Hope this helps you
