Find the distance between the points (2,8) and (-1,9)

Mathematics

Sphinxa [80]3 years ago

Use the distance formula: D=sqrt((x2-x1)^2+(y2-y1)^2)

Plug in:

D=sqrt((9-8)^2+(-1-2)^2)

D=sqrt(1^2+(-3)^2)

D=sqrt(1+9)

D=sqrt(10)

So the distance is about 3.16 units

Hope this helped!

A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th
Anastasy [175]

Answer and Step-by-step explanation:

Let's~solve~your~problem!

<em><u>Formula : </u></em>

<u></u>speed=\frac{distance}{time}

<em><u>Solving for time:</u></em>

Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20}  = 2~hours

Time~taken~to~cover~180~miles~on~the~highway~= \frac{180}{60}=3~hours

Total~Time~=~5~hours

<em><u>Solving for distance:</u></em>

<em><u /></em>Total~Distance=40 + 180 = 220<em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em>\frac{Total~distance}{Total~time}  = \frac{225}{5}  = 44~miles~per~hour<em><u /></em>
