How many lines of symmetry does a triangle have

Mathematics
1 answer:
kow [346]3 years ago
8 0

That depends on the shape of the triangle.

A scalene triangle has no lines of symmetry.
An isosceles triangle has one line of symmetry.
An equilateral triangle has three lines of symmetry.

If my hunch is correct, Watson, there is no triangle
with two and only two lines of symmetry.

write the equation of the ellipse using the given information: the ellipse has foci (0,3) and (0,-3) and major vertices (0,5) an
svetlana [45]

Answer: (x^2)/16 + (y^2)/25 = 1

Step-by-step explanation:

According to the problem we can figure out that the center of the ellipse is (0,0).

Since the foci is (0,3) and (0,-3) we know that the value of c is 3. The major vertices are (0,5) and (0,-5) so the value of a is 5.

If we put this into the equation a^2=b^2 + c^2, we get 25=9+ b^2

We get b^2 is 16

Now since we know that the ellipse is vertical because the x value didn’t change, we know that the b^2 value comes first in the equation. Then the a^2 value which is 25.

Let x specify the number of 16 ounce serving

 

If you buy the mug you acquire the first serving including the mug.

 

So the price of x is:

295 + 50(x - 1)

 

the x - 1 here shows that the first serving with the mug.

And then count the whole thing in cents.

The fee of throwaway cups is 85x

 

So breakeven is computed by:

295 + 50(x - 1) = 85x

295 + 50x - 50 = 85x

245 = 35x

x = 245/35 = 7

 

Checking this will give us:

mug 2.95 + 50*6 = 5.95

disposable

8.5*7 = 5.95

 

So the answer is D.
