Answer:the height of the flagpole is 27.12 ft
Step-by-step explanation:
The wire makes an angle with the ground and forms a right angle triangle with the flag pole. The length of the wire represents the hypotenuse of the right angle triangle. The height of the flag pole and the ground distance from the wire represents the adjacent and opposite sides respectively.
To determine the height of the flagpole, x we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
31² = x² + 15²
x² = 961 - 225 = 736
x = √736. = 27.12 ft
Using the function concept, it is found that:
- Graph B is a function because each value of x corresponds to exactly one y-value.
In a function, <u>one value of the input can be related to only one value of the output</u>.
- In a graph, it means that for each value of x(horizontal axis), there can be only one respective value of y(vertical axis).
In this problem, at Graph A, when x = 5, for example a vertical line crosses the function 3 times, hence there are 3 respective values of y for x = 5, and the same is valid for other values of x, hence it is not a function.
At Graph B, <u>for each value of x, there is only one value of y</u>, hence it is a function.
Hence:
Graph B is a function because each value of x corresponds to exactly one y-value.

Answer:

Step-by-step explanation:
we know that
If CD is parallel to XZ
then
Triangle XYZ is similar to Triangle YCD
therefore
The ratio of their corresponding sides are equal

we have
CX=5\ units, CY=25\ units, YD=20\ units,




substitute the values
