Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.

Answer: 4.26 x 10^2
Step-by-step explanation: you need to move the decimal over 2 spots because it needs to be a number from 1-9. So it would be 4.26. Then the exponent is positive 2 because you are moving the decimal to the left.
This is the graph of 1/x moved 4 units to the left
so its f(x) = 1 / (x + 4)
C
