Answer:
f(-4) = 56
Step-by-step explanation:
f(x) = 3x² - 2x
To find f(-4), substitute -4 for all the values of x in f(x).
f(-4) = 3(-4)² - 2(-4)
Square -4.
f(-4) = 3(16) - 2(-4)
Multiply 3 and 16.
f(-4) = 48 - 2(-4)
Multiply -2 and -4.
48 + 8
Add.
56

a = radius
b = height
c = slant height
15² + h² = 17²
h = 8
Answer:
For covering 
unit area of the entire playground, the amount of sand required is equal to volume of 
buckets of sand.
Step-by-step explanation:
Given -
volume of sand in bucket is able to cover 
area of the entire playground
Thus,
For covering unit area of the entire playground, the amount of sand required is equal to of the total volume of sand in bucket
For covering unit area of the entire playground, the amount of sand required is equal to
For covering unit area of the entire playground, the amount of sand required is equal to volume of buckets of sand.
