Answer:

$y = 250x$

Step-by-step explanation:

<em>The options are not given; however, the question can still be answered.</em>

Given

Direct Proportion:

In 20 minutes, y = 250 bottles

Required

Determine the graph

<em>In the first 20 minutes, y = 250</em>

<em>In the next 20 minutes, y = 250 + 250 = 500</em>

<em>In the next 20 minutes, y = 500 + 250 = 750</em>

<em />

This gives a arithmetic sequence:

250, 500, 750, ........

Next, is to determine the equation of the sequence using;

$T_n = a + (n - 1)d$

In this case;

$T_n = y$

$x = n$

$a = 250$

$d = 750 - 500 = 500 - 250 = 250$

Substitute these values in the above formula;

$y = 250 + (x - 1) * 250$

Open Bracket

$y = 250 + 250x - 250$

Collect Like Terms

$y = 250x + 250 - 250$

$y = 250x$

Hence; the graph that shows the given description is the graph with equation $y = 250x$

Find the exact distance between (5, 3) and (-2, 8).

Brrunno [24]

Answer:

The answer is

<h2> $\sqrt{74} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

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

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, 3) and (-2, 8)

The distance between them is

$d = \sqrt{( {5 + 2})^{2} + ( {3 - 8})^{2} } \\ = \sqrt{ {7}^{2} + ({ - 5})^{2} } \\ = \sqrt{49 + 25} \\ = \sqrt{74} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{74} \: \: \: \: units \\$

Hope this helps you
