What is the distance between (2, -2) and (-8, -2)?
Given:
(2, -2)(-8, -2)To find: The distance between the two points.
Answer:
Formula to find the distance:
[tex]\sf Distance\ =\ \sqrt{\Bigg(x_2\ -\ x_1\Bigg)^2\ +\ \Bigg(y_2\ -\ y_1\Bigg)^2}[/tex]
From the given data, we have:
x₁ = 2x₂ = -2y₁ = -8y₂ = -2Using them in the formula,
[tex]\sf Distance\ =\ \sqrt{\Bigg(-8\ -\ 2\Bigg)^2\ +\ \Bigg(-2\ -\ (-2)\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{\Bigg(-10\Bigg)^2\ +\ \Bigg(-2\ +\ 2\Bigg)^2}\\\\\\\\Distance\ =\ \sqrt{100}\ =\ \bf 10\ units.[/tex]
Therefore, the distance between (2, -2) and (-8, -2) is 10 units.
Hope it helps. :)

The change in altitude of a bird after 2 __ 1 2 seconds was –41 __ 1 4 feet. What was the average change in altitude of the bird in feet per second?
Answer:
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]
Step-by-step explanation:
Given
[tex]Altitude\ Change = -4\frac{1}{4} \ ft[/tex]
[tex]Time = 2\frac{1}{2}\ s[/tex]
Required
Determine the average change
This is calculated as follows:
[tex]Average\ Change = \frac{Altitude\ Change}{Time}[/tex]
This gives:
[tex]Average\ Change = \frac{-4\frac{1}{4}}{2\frac{1}{2}}[/tex]
[tex]Average\ Change = -4\frac{1}{4}/2\frac{1}{2}[/tex]
Convert to improper fractions
[tex]Average\ Change = -\frac{17}{4}/\frac{5}{2}[/tex]
Convert to multiplication
[tex]Average\ Change = -\frac{17}{4}*\frac{2}{5}[/tex]
[tex]Average\ Change = -\frac{17}{2}*\frac{1}{5}[/tex]
[tex]Average\ Change = -\frac{17}{10}[/tex]
[tex]Average\ Change = -1\frac{7}{10} ft/s[/tex]

A computer store buys a computer system at a cost of 463.20$. The selling price was first at $772, but then the store advertised 40% a markdown on the system.Find the current sale price.
The current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
What is the selling price?The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.
Given:
The cost price = $463.20,
The initial selling price = $772,
We know that Markdown= Selling price × markdown rate
Markdown = 772 × 40%
Markdown = 772 × 0.4
Markdown = $308.8
So new selling price = The initial selling price - markdown price
Current selling price = 772 - 308.8
Current selling price = $463.2
Therefore, the current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
