The milligrams of aspirin in a person's body is given by the equation a=500(3/4) ^t, where t is the number of hours since the patient took the medicine. In the equation, what does 3/4 tell us about this situation?

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

it’s supposed to be -4+45=41

step-by-step explanation:

%40

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
