Yes. A regular polygon is equilateral and equiangular; an equilateral triangle is both equilateral and equiangular, so a triangle can be a regular polygon.

Hope this helps!

Find the equation of the circle: y-intercepts 4 and –8, contain (–12, –8)
laila [671]

Answer:

  (x +6)^2 +(y +2)^2 = 72

Step-by-step explanation:

The given points are vertices of a right triangle. The circle circumscribing that triangle (through all 3 vertices) will have its center at the midpoint of the hypotenuse:

  ((0, 4) +(-12, -8))/2 = (-6, -2)

The equation of a circle with center (h, k) through point (a, b) is ...

  (x -h)^2 +(y -k)^2 = (a -h)^2 +(b -k)^2

For center (-6, -2) and point (0, 4), the equation is ...

  (x +6)^2 +(y +2)^2 = (0+6)^2 +(4 +2)^2

  (x +6)^2 +(y +2)^2 = 72

Which length is greater 1/2 meter or 240 centimeters explain
avanturin [10]

Solution:

we have been asked to find

Which length is greater 1/2 meter or 240 centimeters.

To compare the two given lengths, we will have to make both the length in same unit system.

Here 1/2 meter can be written as 50 centimeter , because 1 meter =100cm.

Now its very clear that 240 centimeters is more than 50 centimeters.

Hence we can say 240 centimeters is greater than 1/2 meter .

For which mapped relation is the domain {1,2,3}?
Serga [27]

Answer:

C

Step-by-step explanation:

For any given function, all first input values (x-values/coordinates) in the relation are considered as the domain values. While the output values (y-values/coordinates) make up the range of the given function.

The mapped relation that has a domain of {1,2,3}, is the mapped relation that has 1, 2, and 3 on the input side on our left.

Therefore, the mapped relation in option C is the answer.

A cyclist rode 4.5 miles in 0.4 hours. How fast was the cyclist going in miles per hour
Nookie1986 [14]

Answer:

1)Distance covered by cyclist=3.75 miles.

Time =0.3 hours.

Speed= Distance ÷Time

Speed =3.75÷0.3=12.5 miles per hour.

2) Speed = 12.5 miles per hour, Distance = 4.5 miles .

Time = Distance ÷Speed.

Time = 4.5÷12.5=0.36 hours.

Time taken to cover 4.5 miles is 0.36 hours.
