Make a mapping diagram for the relation.
{(–1, 4), (1, –6), (2, –4), (5, 1)}

answers below

See attachment.

Step-by-step explanation:

The given relation is

{(–1, 4), (1, –6), (2, –4), (5, 1)}

To make a mapping diagram, we write the first coordinates of the ordered pairs in the domain and the second coordinates in the range.

We then use arrows to map the objects in the domain to their corresponding images in the range.

See diagram in attachment.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
