The answer is. A jeranabo
Answer:
8/17 is correct because cosine = adjacent/hypotenuse, and since angle A is theta, or the reference angle, the adjacent of A would be 8, and the hypotenuse is always across the right angle.
15/17 would be sine instead of cosine
Answer:
35
Step-by-step explanation:
Answer:
Speed = 0.0003miles/hr
Step-by-step explanation:
Speed of object = 1 mile/hour
For every meter it travels, its acceleration increases by 1 mile/hour
∆Distance = increase in distance
∆speed = 1 meter
The speed and the distance are constant
Speed = distance/time
Time = distance/speed = 1meter/(1 miles/hr)
Convert meter to miles
1609.34 meters = 1mile
1meter = (1meter × 1mile)/(1609.34 meters)
1 meter = (1/1609.34)miles
Time = distance/speed = (1/1609.34)miles/(1 miles/hr)
Time = (1/1609.34)hr
We are to determine the speed the object would be travelling in half of an hour?
In 1hr, it travels (1/1609.34)miles
In ½hr, it travels = (1/1609.34)(½)hr
Speed = 0.0003miles/hr
It will be travelling 0.0003miles/hr in half of an hour
