Given:

Transformation is

T:(x,y)\to (x-5,y+3)

To find:

The image of A(2,-1).

Solution:

The rule of transformation is

(x,y)\to (x-5,y+3)

To find the image of A(2,-1). Put x=2 and y=-1 in the above rule of transformation.

A(2,-1)\to A'(2-5,-1+3)

A(2,-1)\to A'(-3,2)

Therefore, the image of A(2,-1) is A'(-3,2).

Answer:

  4. height: 5√3 cm; area: 25√3 cm²

  5. 30√2 ft ≈ 42.43 ft

Step-by-step explanation:

4. The height of an equilateral triangle is (√3)/2 times the side length, so is ...

  height = (√3)/2 × (10 cm) = 5√3 cm

The area is given by the formula ...

  A = 1/2bh

  A = 1/2(10 cm)(5√3 cm) = 25√3 cm²

__

5. The diagonal of a square is √2 times the side length, so the distance from 3rd to 1st base is ...

  (30 ft)√2 ≈ 42.43 ft

__

The length of the diagonal of a square is something you should be familiar with. If you're not, you can figure the distance using the Pythagorean theorem.

  d = √(30² +30²) = √1800 ≈ 42.43 . . . feet
