Answer:
B. 
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:
Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)
Take square root of 3
--- approximated
Take π as 3.14
--- approximated
List out the results, we have:
Order from greatest to least, we have:
Hence, the order of arrangement is:
i.e.
Answer:
Step-by-step explanation:
If the engine torque y (in foot-pounds) of one model of car is given by y=−3.75x^2+23.2x+38.8
The engine speed is at maximum if dy/dx = 0
dy/dx = -2(3.75)x+23.2
dy/dx = -7.5x + 23.2
since dy/dx = 0
0 = -7.5x + 23.2
7.5x = 23.2
x = 23.2/7.5
x = 3.093
Hence the maximum torque is 3.09 rev/min
Answer:
64
Step-by-step explanation:
length x width x height= volume
4x8x2= 64
Answer: There are 69 adults and 72 children went to the concert.
Step-by-step explanation:
Let x be the number of adults, and y be the number of children.
x + y = 141
3.5x + 2.5y = 421.5
x + y =141
x = 141 - y
3.5(141 - y) + 2.5y = 421.5
493.5 - 3.5y + 2.5y = 421.5
493.5 - y = 421.5
-y = -72
y = 72
x + y = 141
x + 72 = 141
x = 69
