It took 30 minutes to arrive to each destination
I thinks its 57/40 or as a fraction it's 1.425
Answer:
Option A
Step-by-step explanation:
Good question!
We assume that x lies on the interval 0<=x<=360. We can therefore identify the solution in degrees:

Now we can solve by substitution, and when simplified we get cos(x) = 1/2.
Take the inverse: x = cos^-1(1/2) = π/3 <--- angle in first quadrant
x = (2π-π/3) = 5π/3 <----- angle in fourth quadrant
As you know π/3 in degrees is 60, and 5π/3 = 360-60 = 300
Therefore your solution is the first option, x = 60+n360 and x = 300 + n360
Answer:
C
Step-by-step explanation:
You just plug in the # in the sequence you wanna find,
n=1
60((1)/(2))^(1-1) = 60 (1st term)
--
n=2
60((1)/(2))^(2-1) = 30 (2nd term)
--
n=3
60((1)/(2))^(3-1) = 15 (3rd term)
--
n=4
60((1)/(2))^(4-1) = 7.5 (4th term)
