Answer:
Question 5: A Question 6: B
2x+2x+x+30+x+30=y
6x+60=y
(6x+60)+(-60)=y+(-60)
6x=y-60
6x/6=y-60/6
x=y-60/6
The range of the function is all real numbers greater than 0.
As the domain values increase, the range values decrease.
Each successive output is the previous output divided by 3.
Answer:
15 ft
Step-by-step explanation:
This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x
We're told that the height of the building the ladder is leaning on is, x - 3
Also we're told that the distance at an adjacent from the ladder is 9 ft.
If we use Pythagoras theorem, we have
x² = (x - 3)² + 9²
x² = x² - 6x + 9 + 81
On rearranging, we have
x² - x² = -6x + 90
6x = 90
x = 90 / 6
x = 15 ft
Therefore, the length of the ladder is found to be 15 ft
