We can Notice from the Diagram that the Ladder with Wall Forms a Right Angled Triangle.
We know that In A Right Angles Triangle :
(Hypotenuse)² = (First Leg)² + (Second Leg)²
Here the Hypotenuse is the Length of Ladder and One of the Leg is Length away from the Wall
Substituting the Respective Values, We get :
⇒ 5² + (Second Leg)² = 13²
⇒ 25 + (Second Leg)² = 169
⇒ (Second Leg)² = 169 - 25
⇒ (Second Leg)² = 144
⇒ Second Leg = 12 Feet
⇒ The Ladder reaches a Height of 12 Feet
Option C is the Answer
Answer:
Minimum 8 at x=0, Maximum value: 24 at x=4
Step-by-step explanation:
Retrieving data from the original question:
1) Calculating the first derivative
2) Now, let's work to find the critical points
Set this
0, belongs to the interval. Plug it in the original function
3) Making a table x, f(x) then compare
x| f(x)
-1 | f(-1)=9
0 | f(0)=8 Minimum
4 | f(4)=24 Maximum
4) The absolute maximum value is 24 at x=4 and the absolute minimum value is 8 at x=0.
Let's solve ~
Hence, the correct choice is D
