Answer:

One invariant point;

Point A = (2, 0)

Step-by-step explanation:

The coordinates of the square vertices are;

O = (0, 0)

A = (2, 0)

B = (2, 2)

C = (0, 2)

Therefore, we have by 90° clockwise rotation;

O' = (2, 2)

A' = (2, 0)

B' = (4, 0)

C' = (2, 4)

Therefore, since only A' (2, 0) = A (2, 0), we have only one invariant point on the perimeter of the square when it is rotated 90° about the center (2, 0) which is the point A = (2, 0).

A monument in a park is shaped like a square pyramid. The dimensions are shown in the net. What is the surface area of the monum
vampirchik [111]

The surface area of the monument shaped like a square pyramid is 14 m².

<h3>Area </h3>

Area is the amount of space that is occupied by a two dimensional shape or object.

From the diagram

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²

Area of square = length * length = 2 m * 2 m = 4 m²

Surface area of monument = 4(2.5) + 4 = 14 m²

The surface area of the monument shaped like a square pyramid is 14 m².

How can you solve a rational equation without graphing?
KiRa [710]

Answer:

To figure out the common denominator for these fractions, I'll first need to factor that quadratic in the denominator on the right-hand side of the rational equation. This will also allow me to find the disallowed values for this equation. Factoring gives me:

x2 – 6x + 8 = (x – 4)(x – 2)

The factors of the quadratic on the right-hand side "just so happen" to be duplicates of the other denominators. This often happens in these exercises. (So often, in fact, that if you get completely different factors, you should probably go back and check your work.)
