x + y^2 = 1 is symmetric with the  x-axis

Let's look at the graph of 

x + y^2 = 1 about the  x− and y-axis and the lines y = x and y = − x below.

graph{(x+y^2-1)(y-x)(y+x)=0 [-10, 10, -5, 5]}

X + y^2= 1 is symmetric with the x-axis 

Explanation

The perimeter of a square is the sum of all its sides.

Since all sides of a square are equal, the perimeter is 4 times the length of one side.

So, in this case, the perimeter is:

4 x 5 cm = 20 cm

Explanation

• A subset F of a metric space X is closed if and only if it is equal to its closure (F = F°).
• This means that F contains all its limit points, and no other points.

Explanation

the adjacent angle to the 120-degree angle can be calculated as follows:

180 degrees - 120 degrees = 60 degrees 

Explanation

The word CHORD has 5 distinct letters: C-H-O-R-D.

When taking all the letters together, the number of ways to arrange them is equal to the number of permutations of 5 items, which is calculated as:

5! = 5 × 4 × 3 × 2 × 1 = 120

Explanation

Let's denote the original side of the cube as s. The original volume is s³.

If the side is doubled, the new side is 2s. The new volume is (2s)³ = 8s³.

The new volume is 8 times the original volume.

Explanation

• A combination is a selection of objects taken some or all at a time, without regard to order.
• It is a way of choosing items from a collection, where the order of selection does not matter.
• For example, choosing 3 books from a shelf of 10 books is a combination.
