Answer:
12cm
Step-by-step explanation:
Answer:
S(-2,12)
y= -2(x+2)²+12
Location of coordinate axes:
y=0 → x= -2±√6 (-2-√6,0) (-2+√6,0)
x=0 → y=4 (0,4)
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>
Answer:
10
Step-by-step explanation:
<u><em>45×60=2700</em></u>
<u><em>And to check divide </em></u>
<u><em>2700÷60=40</em></u>
<u><em>2700÷40=60</em></u>
