Answer:

[See Below]

Step-by-step explanation:

✦ First split the equation in little pieces and solve them:

✧ 4 - 16 = -12

✧ 4 + 4² = 20 (4² = 16)

✦ Now divide them:

✧ -12 ÷ 20 = -0.6

So I'm guessing you're trying to simplify 4²... so it'd be 16 because none of the choices are the simplified version of the problem.

City A is due north of City B. Find the distance between City A (36 degrees 6 prime36°6′ north latitude) and City B (21 degre

vitfil [10]

Answer:

distance = 994.75 miles

Step-by-step explanation:

given data

City A = 36°6′ = 36° + $\frac{6}{60}$ = 36.1° = 36.1° × $\frac{\pi}{180}$ = 0.6297 rad

City B = 21°42′ = 21° + $\frac{42}{60}$ = 21.7° = 21.7° × $\frac{\pi}{180}$ = 0.3785 rad

multiply by π/180 to convert the degree to radian

radius of Earth = 3960 miles

to find out

distance between City A and City B

solution

we first get here central angle between A and B city is

central angle between A and B city = 0.6297 rad - 0.3785 rad

and

now by arc length so we get distance

distance = 3960 miles × (0.6297 rad - 0.3785 rad )

distance = 994.75 miles
