The answer is 10 to the power of 10. Its becase first 10 simplify with the base of the logarithm (gives 1) and then we have 1 multiply times 10.

Answer:
D
Step-by-step explanation:
D is a function because it passes the vertical line test, meaning that you can draw a vertical line anywhere through the graph and it will only it the lines one time.
 
        
                    
             
        
        
        
Answer: 14 feet 
Step-by-step explanation: the difference between the shadow of the building and the building is 4 feet so the difference between the shadow of the statue and the statue is 4 feet so the answer is 14 feet.
 
        
             
        
        
        
Answer:
<h3>
               f(x) = 6(x - 2)² + 3</h3>
Step-by-step explanation:
f(x) = a(x - h)² + k    - vertex form of the equation of the parabola with vertex (h, k)
"the parabola opens upward" means:  a>0
"the parabola has x = 2 as an axis of symmetry" means:  h = 2
so f(x) = a(x - 2)² + k
"the parabola contains the point (1, 9)" means:
9 = a(1 - 2)² + k 
9 = a(-1)² + k
9 = a + k
k = 9 - a
"the parabola contains the point (4, 27)" means:
27 = a(4 - 2)² + k 
so:
27 = a(2)² + 9 - a 
27 = 4a + 9 - a
3a = 18
 a = 6
and  k = 9 - 6 = 3
Therefore the vertex form for this parabola is: 
                                      <u> f(x) = 6(x - 2)² + 3</u>
