A pilot is flying a CRJ-900 from Phoenix, Arizona, to Louisville, Kentucky. The aircraft cannot take off or land if the temperat
ioda

We need to find an inequality that represents the possible landing or take of conditions of an aircraft, the required graph and one case where the inequality will be tested.

The required inequality is -40.

The graph represents the allowable temperature range in which the aircraft can takeoff or land.

The pilot could not have taken off on June 1990, the temperature in Phoenix, Arizona.

Let the temperature be denoted by x

The temperature cannot be at or below -40^{\circ}\text{F}, so

x>-40

The temperature cannot be at or above 118^{\circ}\text{F}, so

x

The inequality will be -40.

In the graph it can be seen that all points between -40 and 118 falls in the shaded region but it will exclude the points -40 and 118.

The graph represents the allowable temperature range in which the aircraft can takeoff or land.

The temperature in June 1990 in Phoenix, Arizona was 122^{\circ} which is more than 118^{\circ}\text{F}.

Hence, the pilot could not have taken off on this day.

The cost of painting the total outside surface of a closed cylindrical tank at 60 paise per meter squae is Rs237.60. The height
valkas [14]

Answer:

volume=509.25 dm^{3}

Step-by-step explanation:

Curved surface area=\frac {237.6}{0.6}=396 dm^{2}=2\pi R(R+H) where R is radius and H is height

Since H=6R then curved surface area=2\pi R(R+6R)=14\pi R^{2}

Therefore,  

396 dm^{2}=14\pi R^{2} and making R the subject

R=\sqrt {\frac {396}{14\pi}}=\sqrt {(9.003622)}= 3.000604 m

Therefore, H=6R=6*3.000604=18.00362 m

Volume=\pi R^{2}H=\pi*3.000604^{2}*18.00362=509.2453 dm^{3}

Therefore, volume=509.25 dm^{3}
