Answer:
5c^2 +6c +13
Step-by-step explanation:
so we can see than 5c^2
and 13c - 7c are the same = 6c 
and 4 +9 = 13 
so answer will 5c^2 +6c +13
 
        
                    
             
        
        
        
The correct answer that would complete the given statement above would be 59. The measurement of 0.059 seconds is equal to 59 milliseconds. To convert this, you need to know that in every 1 second, there are 1000 milliseconds. And for 1 millisecond, there is 0.001 second. 
        
                    
             
        
        
        
Answer:
21 kilometers
Step-by-step explanation:
Let the height be  . Then, the length of the base is
. Then, the length of the base is  . The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to
. The formula for the area is of the triangle is given by base*height/2. Therefore, the area of the triangle is equal to  , which is in turn equal to 441. Since
, which is in turn equal to 441. Since  must be positive, then
 must be positive, then  , meaning that the height is
, meaning that the height is  kilometers.
 kilometers.
 
        
             
        
        
        
The formula for the volume of a cone, V, is:
V = [1/3] * π * (radius)^2 * height
Here radius = 6 feet / 2 = 3 feet
Height = 15 feet 
V = [1/3] π (3 feet)^2 * 15 feet = 45π feet^3
Answer: 45π feet^3
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
area of rectangle=11×5=55 cm²
area of triangle=1/2×5×3=15/2=7.5 cm²
area of shaded region=55-7.5=47.5 cm²
