Answer:
8.55 ft
Step-by-step explanation:
These two triangles are similar, which means that the ratio of their corresponding sides will be the same.
The height of the 4-foot ladder and the height of the 9-foot ladder correspond, while the length of the 4-foot ladder corresponds to the length of the 9-foot ladder. So, we can write the ratio:
, where x is the height of the 9-foot ladder.
Cross-multiply:
4 * x = 3.8 * 9
4x = 34.2
Divide by 4:
4x/4 = 34.2/4
x = 8.55
Thus, the height of the 9-foot ladder is 8.55 feet.
Hope this helps!

Answer:
The function input is -20 when the output is 25
Step-by-step explanation:
we have
where
y is the dependent variable or output
x is the independent variable or input
If the output is 25
then
y=25
substitute
Solve for the function input is the same that solve for x
Isolate the variable x
Adds 5x both sides
subtract 25 both sides
Divide by 5 both sides
therefore
The function input is -20 when the output is 25
