<u>Trigonometric Equations</u>
Solve
for x in [0,2π].
Dividing by 3:
Solving for 2x by using the inverse sine function:
There are two angles in the first turn of the trigonometric circle whose sine is 0:
2x=0
2x=π
Dividing by 2, we get the first two solutions:
x = 0
Since the argument of the sine is double, we look for solutions in the next turn of the circle, that is:
Again, dividing by 2:
No more solutions can be found, thus the solutions are:
What is being asked here is to convert the value above from units of yards per second into miles per hour. To do this, we need a conversion factor to multiply to the value for it to be converted to another units. We do as follows:
Conversion Factors
1 mile = 1760 yards
1 hr = 3600 s
<span>3 yd/s ( 1 mile / 1760 yards ) (3600 s / 1 hr) = 10.8 miles per hour</span>
Answer:
32 meters
Step-by-step explanation:
If the trees shadow is half the height of the buildings shadow, then the tree is half the size of the building
