Can you think of three examples of real world parallel and/or perpendicular lines? Explain why they are important in the real-wo
Naddika [18.5K]

Answer: The road, crucifix/cross, sidewalks, railroads, and so much more.

Step-by-step explanation: Roads are parallel so that everyone can get to the same place in different lanes. This is important because lines that aren't parallel will inevitably meet, meaning that a highway would eventually merge its two lanes. This happens, but most of the highway is parallel. The same is true of sidewalks and railroads. The crucifix/cross is a Christian symbol, and while I'm not Christian, I'm sure it's important to a lot of people who are.

What is the approximate area of the circle shown below?
Lelu [443]

Hey there!

Formula: πr^2

r = radius

pi = 3.1415926535898 (but we can say it approximately equals 3.14)

Your equation (3.14)(4.2)^2 = answer

4.2^2 = 4.2 × 4.2 = 17.64

New equation: 17.64 × 3.14 = 55.3896

We round our answer to the nearest tenth

Answer: 55.4 ☑️

Good luck on your assignment and enjoy your day!

Write the equation of the line?<br><br><br><br> write the equation in standard form.
vlabodo [156]
Answer: y= 1

This because the line has no slope so the equation really looks like this if we were to follow the y=mx+b format.

y=mx+b
y= 0x + b

because the number "0" multiplied by any value is still zero we can exlude that from the final equation of the line. In this case since m=0, the line is y=b.

b is the y intercept, or the value of y when x = 0.

So, because y=1 when x is 0, "b"= 1

y=b
y=1
