The base of a ladder is placed 5 feet away from a 13 foot tall wall. what is the minimum length ladder needed to reach the top of the wall (rounded to the nearest foot)?
a) 12 ft
b) 13 ft
c) 14 ft
d) 15 ft

C) 14 ft

Step-by-step explanation:

Let l be the length of ladder ,

The distance of ladder from the wall = 13 ft,

And, the height of wall = 5 ft,

Since, the length of ladder is minimum when the wall is straight,

In this condition,

Hence, the approximate minimum length of the ladder is 14 ft.

the height of the surface increases from the center out to the sides of the road

it is c!

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
