Answer:
A
Step-by-step explanation:

as 0≤θ≤90
so θ/2 is also in 0≤θ≤90
hence sin θ/2 and cos θ/2 are positive.

well it goes over the x axis and it changes the y cords to positive
Answer: what is the distance between points A and B? 14 Units
Step-by-step explanation: The first thing that you need to do is to draw the number line shown, then we mark the two points mentioned: -2 and 12 and encircle them, following this we are going to count to the right, starting on point A, -2, and finishing on point B, 12. After we count, we are going to see that the distance between the two points is 14 units.
Answer:
1.17 × 10^2
Step-by-step explanation:
Diameter of the sun is about 1.4 × 10^6 km
1.4*10^6 km = 1,400,000
Diameter of the planet venus is about 12000 km
12000 km = 1.2 × 10^4
Ratio of the diameters
Sun : Venus
1.4 × 10^6 km : 1.2 × 10^4
1.4 × 10^6 km / 1.2 × 10^4
1.4 / 1.2 × 10^6-4
1.166 × 10^2
Approximately
1.17 × 10^2
The approximate ratio of the diameter Sun to Venus is 1.17 × 10^2
