X- int : (1,0)
y-int: (0,-2)
to find x-int plug in 0 for y
0= (x-1)2
Solve for x
2x-2=0
2x= 2
x=1
to find y-int plug in 0 for x
y=(0 - 1) 2
y= (-1)2
y= -2
Answer is false, because every function is a relation but every relation is not a function :) (Please mark me brainliest)
I think the answer is 36 but i could be wrong
To solve this proble you must apply the proccedure shown below:
1. You have that:
- <span>David is standing 5000 feet away from the base of a cell phone tower. and the angel of elevation from his eyes to the top of the tower is 78 degrees.
- David’s eyes are 6 feet.
2. Therefore, you have:
Tan</span>α=opposite/adjacent
Tanα=x/5000
x=(5000)(Tan(78°))
x=23,523.15 feet
3. Then, you have that the height of the tower is:
h=6 feet+23,523.15 feet
h=23,529.15 feet
The answer is:23,529.15 feet
