Step-by-step explanation
The answer to your question is A
Answer:
it is different by the numbers are changing so the answers are different and the 3 is one digit and 23 is two digits.
Step-by-step explanation:
Answer: Speed = 5.6 mph
Oxygen consumption = 71.6 mL/lb/min
Step-by-step explanation: For the oxygen consumption to be the same, functions must be equal:
f(x) = g(x)

Resolving:





x=0
5x - 28 = 0

x = 5.6
<u>The speed when the oxygen consuption is the same is </u><u>5.6 mph</u><u>.</u>
For the level of oxygen consumption:
f(5.6) = g(5.6)
g(5.6) = 11*5.6 + 10
g(5.6) = 71.6
<u>The level of oxygen consumption is </u><u>71.6 mL/lb/min</u>
75 = 5 x 3 x 5
We can solve this using a factor tree.
