Sine and cosine has period of 2π and tangent has period of π
So basically same question as sin(0), cos(0), and tan(0)
sin(0) = 0
cos(0) = 1
tan(0) = sin(0) / cos(0) = 0 / 1 = 0
So final answers are sin(360°) = 0, cos(360°) = 1, tan(360°) = 0
Answer: 2^5
Step-by-step explanation:
Formula: 2*x - For everyday
2*2 - Monday
4*2 - Tuesday
8*2 - Wednesday
16*2 - Thursday
So for Friday you can spell 32 words which is 2^5
Answer:
The distance between the two train stations is 1728 km
Step-by-step explanation:
The speed of the bus = 54 km/h
The speed of the truck = 48 km/h
When the bus and truck meet again, the distance covered by the bus = 216 km more than he distance traveled by the truck
Let the distance between the two train stations = x
Let the location where they first meet be y from station A we have;
The location where they meet again = y - 216 km
Therefore, we have;
Location where they
The time for the truck and the bus to meet again = t
Therefore, 54 × t - 48 × t = 216 km
6·t = 216 km
t = 36 hours
Therefore, the time for the bus to travel x + 216 km = 36 hours
54 × 36 = 1944 = x + 216
x = 1944 - 216 = 1728 km
The distance between the two train stations = 1728 km.
Answer:
1.8 × 10^10
Step-by-step explanation:
(7.2 × 10 = 72)
(72) ÷ (4 × 10^-9) = 1.8 × 10^10
