Problem 82

The record January temperatures (in degrees Fahrenheit) for a city are given. Find the distance between the numbers to determine the range of temperatures for January.Flagstaff, Arizona: lowest: \(-22^{\circ} \mathrm{F}\) highest: \(66^{\circ} \mathrm{F}\)

Problem 82

Calculator Write the keystrokes you can use to evaluate \(\sqrt[3]{(-5)^{5}}\) in one step on your calculator.

Problem 83

Complete the statement with \(<,=\), or \(\geq$$\sqrt{5}+\sqrt{3} \quad \sqrt{5+3}\)

Problem 84

Complete the statement with \(<,=\), or \(\geq$$\sqrt{3}-\sqrt{2} \quad \sqrt{3-2}\)

Problem 85

Complete the statement with \(<,=\), or \(\geq\)5 \(\sqrt{3^{2}+2^{2}}\)

Problem 86

Complete the statement with \(<,=\), or \(\geq$$5 \quad \sqrt{3^{2}+4^{2}}\)

Problem 87

Complete the statement with \(<,=\), or \(\geq$$\sqrt{3} \cdot \sqrt[4]{3} \quad \sqrt[8]{3}\)

Problem 88

Complete the statement with \(<,=\), or \(\geq$$\sqrt{\frac{3}{11}} \quad \frac{\sqrt{3}}{\sqrt{11}}\)

Problem 93

The escape velocity (in meters per second) on the moon is \(\sqrt{\frac{2\left(6.67 \times 10^{-11}\right)\left(7.36 \times 10^{22}\right)}{1.74 \times 10^{6}}}\) If all the fuel is consumed during launching, will a rocket with an initial velocity of 2000 meters per second escape the gravitational field of the moon?

Problem 94

The escape velocity (in meters per second) on Mars is \(\sqrt{\frac{2\left(6.67 \times 10^{-11}\right)\left(6.42 \times 10^{23}\right)}{3.37 \times 10^{6}}}\) Will an object traveling at 6000 meters per second escape the gravitational field of Mars?
