Answers

Answer 1
Answer:

Answer:

C.(-3, -3) and (-3,3)

Step-by-step explanation:

When we have a vertical line the slope is undefined.

That means the x values stay the same

C.(-3, -3) and (-3,3)

This has the same x values

m = (y2-y1)/(x2-x1)

   =( 3- -3)/(-3 - -3)

   (3+3)/(-3+3)

   6/0

  undefined

Two cars start from the same place driving at the same rate, one heading north and the other heading east. After two hours the car heading north has traveled 150 miles and the car heading east has traveled 100 miles. How far apart are the cars at this time?

Answers

Answer:

180.2776 miles

Step-by-step explanation:

Given that two cars start from the same place.

One car is heading towards north and another east.

that means the two cars travel path make 90 degrees at the origin.

Imagine the triangle with one vertex at the starting place right angled at 90 and other two vertices are the locations of the two cars.

We find this triangle has legs of  150 miles and 100 miles respectively.

The distance between the two cars = length of the hypotenuse of the right triangle with legs 150 and 100 miles

= √(150^2)+100^2 (Using Pythagorean theorem)

= √32500

= 180.2776 miles

Answer:

they are 250 miles apart

|150|+|-100|=250

it is 42 1/2 miles from eaton to baxter, and 37 4/5 miles from baxter to Wellington. how far is it from eaton to Wellington, if you go by way of Baxter??

Answers

Our Given information is:

Easton >> Baxter = 42.5 miles
Baxter >> Wellington = 37.8 miles

Therefore, if we wanted to find how far it was from Eaton to Wellington, assuming that we went by way of Baxter, all we would have to do is add the mileage amounts together.

42.5 + 37.8 = 80.3

Therefore, it is 80.3 or 80 3/10 miles from Eaton to Wellington by way of Baxter.
