Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x =
Given
ln(x + 4) = 1 , then
x + 4 = ( subtract 4 from both sides )
x = - 4 = - 1.28 ( to the nearest hundredth )

Calculation:
The ladder must be 9.4 ft to reach the top of the building
Here, we want to get the length of the ladder that will reach the top of the building
Firstly, we need a diagrammatic representation
We have this as;
As we can see, we have a right triangle with the hypotenuse being the length of the ladder
We simply will make use of Pythagoras' theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
Thus, we have;
