The buildings height was 64.23 (meters) to 2dp

Step-by-step explanation:

This is because the pole shadow = 44.3333% increase to get to 3ft

Seeing that 1.67 was the shadow and beside it the building shows 44.5 we just multiply it by the percentage and to not add one (1) to the decimal to add if not adding or showing what 44.33% becomes.

44.5 x 1.443333 =64.2283185  and sum (add) as its an increase = (44.5 + 19.72831 = 64.2283185) So 19.73 to 2dp is the difference without the 1 used and without being seen.

This is the hidden increase as we just say 44.33% of 44.5 ft But as we used the 1. to represent the x100.

We find 44.33% of 44.5 finds us the buildings exact measure to 2dp = 64.22m

Converted (= 210.72 feet to 2dp)

Hope this helps.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
