Answer:
22.86 centimeters (9 inches into cm is 22.86 cm)
 
        
             
        
        
        
Give each month a number:
 January = 0
February = 1
 March = 2
April = 3
Now set X to 3 in the equation ad solve for t.
t = -30cos(x/6) +60
t = -30cos(3/6) +60
t = 33.672 degrees. ( Round as necessary)
You would need to change the +60 to a new starting point based on what the rise in temperature is due to global warming.
 
        
             
        
        
        
Answer: 
 The radius is: 
Step-by-step explanation:
 The equation of a circle in center-radius form is:
 
 Where the center is at the point (h, k) and the radius is "r".
 So, given the equation of the circle:
 
 You can identify that:
 
 Then, solving for "r", you get that the radius of this circle is:
 
 
        
                    
             
        
        
        
Is this the whole question?
        
             
        
        
        
Answer:
C).
Step-by-step explanation:
One of the points on the graph that the path of bike b crosses is (6,60).
When you divide this to find the unit rate you get 10/1 therefore the equation of bike b= y+10X
