We are given the function below;

PART A
We then proceed to find if the function has a minimum or maximum value. To find if the function has a minimum or maximum value. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum.
ANSWER: From the above, we can see that x^2 is negative, hence the function has a maximum
PART B and C
To find the minimum or maximum value, we would plot the graph of the f(x). The graph can be seen below.
From the graph, the black point helps answer part A and part B. 
ANSWER: The function's maximum value is f(x)=2. 
This is the point where the slope of the graph is equal to zero
ANSWER: The maximum value then occurs at x= -1
 We can also solve this by differentiating the function.
 
 
        
             
        
        
        
Answer:
10.24
Step-by-step explanation:
Area of a circle=sides²
Area of a circle=(3.2)²=3.2(3.2)=10.24
 
        
             
        
        
        
Answer:
must remember triangle interior angle is 180.
and they said the triangle is similar so they have similar angle
180-95-58=27
 
        
             
        
        
        
120 + 0.40m = 50 + 0.50m
120 - 50 = 0.50m - 0.40m
70 = 0.10m
70/0.10 = m
700 = m....they will be the same at 700 miles
