Writing exponential functions from scenarios a patient is given a 50 mg dose of medicine. the medicine's effectiveness decreases every hour at a constant rate of 40%. what is the exponential decay function that models this scenario? how much medicine will be left in the patient's system after 2 hours?
a. f(x) = 50(0.40)x; 8 mg
b. f(x) = 50(0.60)x; 18 mg
c. f(x) = 50(40)x; 80,000 mg
d. f(x) = 50(60)x; 180,000 mg

The answer is B - f(x) = 50(0.60)x; 18 mg

Step-by-step explanation:

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
