Answer:
15.2 feet
Step-by-step explanation:
We use Pythagorean Theorem to find the height.
The hypotenuse of the formed triangle = length of ladder = 16 feet
base = 5 feet
let h = height of house
16 ^2 = 5^2 + h^2
256 = 25 + h^2
231 = h^2
h = root(231) = 15.1986 feet
Answer:
A. Positive I'm sorry if I got this wrong answer
The barn, the ground, and the ladder form a right triangle. If we represent the height on the barn by y, then the Pythagorean theorem tells us
... hypotenuse² = (side1)² + (side2)²
... (12 ft)² = (3 ft)² + y² . . . . . . . . . . . . fill in given information
... 144 ft² - 9 ft² = y² = 135 ft² . . . . . .subtract (3 ft)²
... y = 3√15 ft ≈ 11.6 ft . . . . . . . . . . . take the square root
The ladder reaches 11.6 feet high on the barn.
A: Speed is Independent as it can be anything with no restrictions. Gas mileage is dependent as it relies on the value of speed for its value to be decided.
B: The first letter of speed is "S" so it can represent the variable. The first letter of mileage is "M" so the variable can be represented by that letter. It really can be any letter.
C: no context
D: no context
