Answer:

pre-image XYZ is X (2, 2), Y (6, 0), Z (1, -1)

The above is the second option in your question.

Step-by-step explanation:

a triangle has points X' (-2, 2), Y' (0, 6), Z' (1, 1)

To rotate the above triangle -90° about the origin you invert the x & y values and change the sign on the new y value.

pre-image XYZ is X (2, 2), Y (6, 0), Z (1, -1)

Answer: 15

Step-by-step explanation: Label the tree with 4m for the height of the tree and the base of the triangle 15m for the shadow it cast. The angle is adjacent to 15m and opposite to 4m making the equation you use tanx=4/15 which when you solve becomes tan^-1(4/15) which gives you 15.

Find the volume of the cone.

juin [17]

The answer is 48π units³ or 150.72 units³.

To find the volume of the cone, use the formula : <u>1/3 × πr²h</u>

We are given that r = 6 and h = 4.

Solving :

V = 1/3 × π × 6² × 4
V = 12 × 4 × π
V = 48π units³ (in terms of π)
V = 150.72 units³
