Clara is taking a medicine for a common cold. Her body metabolizes the medicine over a certain time interval. The table below sh

ows the amount of medicine f(t), in mg, that was present in Clara's body after time t.
t (hours) 1 2 3 4 5
f(t) (mg) 236.5 223.73 211.65 200.22 189.41


Heidi was administered 300 mg of the same medicine. The amount of medicine in her body f(t) after time t is shown by the equation below.

(t) = 300(0.946)t

1) Let's write the data of Clara's table just to have them ready to compare

t (hours)          1               2               3             4               5
f(t) (mg)         236.5    223.73      211.65     200.22       189.41
Change(mg)     -          -12.77       -12.05     -11.43      -10.81

2) Now calculate the amount of medicine as per Heide's formula, 300(0.946)^t:

 t (hours)             1             2                 3             4               5
f(t) (mg)           283.8    268.48         253.98     240.26      227.29
Change (mg)                 -15.12          -14.5     -13.72          -12.97

Now you can compare the data and realize that the rate of change of Heide is greater than the rate of change of Clara, meaning that Heide eliminates the medicine faster than Clara.

An engineer stands 200 feet from a tower and sights the top of the tower at a 45° angle of elevation. Find the height of the tow
Alik [6]
Drawing a diagram of a triangle may be helpful. The hypotenuse is irrelevant, but the vertical leg and the horizontal leg are useful. Since we know the engineer is looking up at a 45 degree angle from a distance of 200 feet, we can label the vertical leg the "opposite", since it is on the opposite side of the angle we are given. The horizontal leg then becomes the "adjacent". You can then use trigonometry to solve for the opposite. 
The options are:
sin(theta)= opposite/hypotenuse
cos(theta)= adjacent/hypotenuse
tan(theta)= opposite/adjacent
Since we don't care about the hypotenuse, the last equation is the one to use. The angle we are given can be substituted in for theta:
tan(45)= x/200
1.61977519= x/200
x= 323.955038 feet
