Answer:
 h = 4x ^ 3 + 18
Step-by-step explanation:
The first thing you should know for this case is that the area of a triangle is given by:
 A = (1/2) * (b) * (h)
 Where,
 b: base.
 h: height.
 Clearing the height we have:
 h = ((2) * (A)) / (b)
 Substituting the values
 h = ((2) * (14x ^ 5 + 63x ^ 2)) / (7x ^ 2)
 Simplifying the expression:
 h = ((2) * (2x ^ 3 + 9))
 h = 4x ^ 3 + 18
 answer
 an expression to represent its height is
 h = 4x ^ 3 + 18
 
        
             
        
        
        
Answer:
129
Step-by-step explanation:
Considering the survey to be representative, you can simply multiply the share of students <em>p</em> preferring “Track & Field” with the whole school population at the same time to estimate the number of such students in the whole school.
First we need to find the relative share <em>p</em> of such answers in the study by dividing it by the sum of answers, assuming that the table is complete for that random sample:
<em>p</em> = 4/(8 + 5 + 4) = 4/17
Then for the whole school we get 550 <em>p</em> ≈ 129.4
 
        
             
        
        
        
9xh = total cost of the hat 
9 per hat - 4 = $5 each scarf
h = hat 
s = scarf
(9xh) + (5x s)
(9x7) + (5x9) = 108
