How tall is the flagpole? X 6 ft 15 ft 4.5 ft

Mathematics
1 answer:
sweet-ann [11.9K]3 years ago
3 0

Answer:

x = 20 ft

Step-by-step explanation:

We can use similar triangles and ratios to solve

4.5 ft         6 ft

--------- = ---------------

15 ft             x ft

Using cross products

4.5x = 15*6

4.5x =90

Divide each side by 4.5

4.5x/4.5 = 90/4.5

x =20

The relation t relates x to y. To determine if it is a function, see if one x value can give two different y values. Since each x value only has one y value, the relation is a function. To check if the inverse is a function, see if any one y value will give multiple x values. By inversing t, there are two values of x for the value of y = -4 (x = 4 and x = 6), so this is NOT a function.

Answer: Relation t is a function. The inverse of relation t is NOT a function.
