Answer:
log(base 3)(d/12) = log(base 3)d - log(base 3)12
Step-by-step explanation:
Well, I am not exactly sure if this is what your asking but one foot is twelve times the size of a foot.
Answer:

Step-by-step explanation:
Given the logarithm function

For logarithmic equations,
is equivalent to
such that
and 
In current case:



Substituting the values of
and
into the equation 

Length = 4/5 ft
area = 3/10 ft.
Width = 3/10 ÷ 4/5 ft
= 3/10*5/4 ft
= 3/8 ft
Perimeter = 2(L+W)
= 2(4/5+3/8) ft
= 2(32+15)/40 ft
= 47/20 ft
= 2.35 ft
Answer:
F(x) = -3(x + 2)² - 2
Step-by-step explanation:
In the picture attached, the graph is shown.
F(x) has the form a(x - h)² + k, where (h, k) is the vertex of the parabola. We can see in the graph that the vertex is located at (-2, -2), then F(x) = a(x + 2)² - 2. If a > 0 the parabola opens upward, if a < 0 the parabola opens downward. We can see in the graph that the parabola opens downward, then the correct answer is F(x) = -3(x + 2)² - 2
