50
Step-by-step explanation:
150-100 = 50
The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7

Answer: First and last option
The birds began 1320 miles from the equator.
The birds are flying toward the equator at a rate of 60 mph.
Step-by-step explanation:
Note that the function f(x) is a linear function.

If x represents the number of hours and f(x) represents the distance from the equator, then x = 0 means that the first hour has not yet elapsed.
When x = 0 then:
.
This means that the initial distance at which the birds of the equator are located is 1320 miles.
Then when x = 1 then:

When x = 2 then:

As x increases by one unit then the distance of the birds to the equator decreases by 60 miles. This means that birds travel at a speed of 60 miles per hour
