Answer:
23.3333333 miles per hour
23 1/3 miles per hour
10.43093333333333 meters / second
Step-by-step explanation:
Take the distance and divide by the time to find the speed
70 miles / 3 hours
1 mile = 1609.34 meters
1 hours = 3600 seconds
70 miles /3 hours * 1 mile /1609.34 meters * 1 hours / 3600 seconds
10.43093333333333 meters / second
Answer:
Cosy° = 
Step-by-step explanation:
From the picture attached,
By applying all trigonometric ratios in the given right triangle,
Siny° = 
= 
tany° = 
= 
Therefore, Cosy° = 
Cosy° =
Therefore, Cosy° = will be the answer.
Answer:
1679616
Step-by-step explanation:
It would be equivalent to x=8
Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
