Need ! a mountain climber is at an elevation of 10,000 feet. if she descends 2,000 feet a day, which equation would be used to show how many days it will take to reach sea level (0 feet)? 10,000 ÷ 2,000 -10,000 ÷ 2,000 -10,000 ÷ (-2,000) 10,000 ÷ (-2,000)

-10,000 / -2000, although 10,000/2000 gives the same answer.

Step-by-step explanation:

The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.

Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

what are the answer choices given for this problem?
