The altitude of Death Valley, California, is 282 feet below sea level. A hot air balloon is launched from the bottom of Death Va

Nadya [2.5K]

The altitude is 177 feet below sea level after being lowered.

The balloon rises 120 feet after 12 seconds and then is dropped 15 feet. So 120 - 15 = 105. And 282 - 105 = 177

An airplane on autopilot took 7 hours to travel 4,914 kilometers. What is the unit rate for kilometers per hour?

snow_lady [41]

Distance traveled by an airplane in 7 hours = 4,914 kilometers

We have to determine the unit rate for kilometers per hour.

So, distance traveled by an airplane in 1 hour = $4,914 \div 7$

= 702 kilometers.

So, an airplane will travel 702 kilometers in an hour.

Therefore, the unit rate for kilometers per hour is 702 km per hour.

Hi, I don’t understand this question

meriva

Given that

z₁ = 15 (cos(90°) + i sin(90°))

z₂ = 3 (cos(10°) + i sin(80°))

we get the quotient z₁/z₂ by dividing the moduli and subtracting the arguments:

z₁/z₂ = 15/3 (cos(90° - 10°) + i sin(90° - 10°))

z₁/z₂ = 5 (cos(80°) + i sin(80°))

so that z₁ is scaled by a factor of 1/3 and is rotated 10° clockwise.

HELP GEOMETRY PLEASE

Alexandra [31]

For each of the problems, twice the angle formed by the chords is equal to half the sum of the angles of the arcs.

So, for the first problem, we have $94 \cdot 2 = x+103$ , so $x = 188 - 103 = 85$ .

For the second, $102 \cdot 2 = x + 118$ , so $x = 204 - 118 = 86$ .

For the last problem, $106 \cdot 2 = x + 88$ , so $x = 212 - 88 = 124$ .

Feel free to comment below if you have any questions!
