m (ACD)=m (ABD)
4x+4=6x-14
2x=18
x=9
m (ACD)=4x+4 =4.9+4=40
16 3/4 + 12 3/4
16 +12 = 28
3/4 +3/4 = 1 1/2
28 + 1 1/2 = 29 1/2 hours total

Answer:
12 feet
Step-by-step explanation:
Given in the question,
horizontal distance from sister to rock wall = 5.5 feet
diagonal distance from sister to rock wall's peak = 13.42 feet
<h3>
To find the height </h3>
As we know this figure make a right angle triangle, so we will apply pythagorus theorem
hypotenuse² = height² + base²
13.42² = height² + 5.5²
13.42² - 5.5² = height²
149.85 = height²
height = √149.85
height = 12.24 feet
Approximate height of her rock wall to the nearest tenth = 12 feet
Answer: a) -24
b) 
c) 4
Step-by-step explanation:
a) To determine the value of (fg)', use the product rule of derivative, i.e.:
(fg)'(x) = f'(x)g(x) + f(x)g'(x)
(fg)'(5) = f'(5)g(5) + f(5)g'(5)
(fg)'(5) = 6(-5) + 3(2)
(fg)'(5) = -24
b) The value is given by the use of the quotient rule of derivative:
![(\frac{f}{g})'(x)=\frac{f'(x)g(x)-f(x)g'(x)}{[g(x)]^2}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%27%28x%29%3D%5Cfrac%7Bf%27%28x%29g%28x%29-f%28x%29g%27%28x%29%7D%7B%5Bg%28x%29%5D%5E2%7D)
![(\frac{f}{g})' (5)=\frac{f'(5)g(5)-f(5)g'(5)}{[g(5)]^2}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bf%7D%7Bg%7D%29%27%20%285%29%3D%5Cfrac%7Bf%27%285%29g%285%29-f%285%29g%27%285%29%7D%7B%5Bg%285%29%5D%5E2%7D)
c) ![(\frac{g}{f})'(5)=\frac{g'(5)f(5)-g(5)f'(5)}{[f(5)]^{2}}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bg%7D%7Bf%7D%29%27%285%29%3D%5Cfrac%7Bg%27%285%29f%285%29-g%285%29f%27%285%29%7D%7B%5Bf%285%29%5D%5E%7B2%7D%7D)
