When a person has a cavity filled, the dentist typically administers a local anesthetic. Alle office, one's mouth often remains numb for several more hours. If the anesthesia wears off using the
model A = A, e-0.5t and the patient was given 400mg of the anesthesia, how long until only 40mg are
remaining in their system?

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

i cant answer this, theres no table. sorry man

step-by-step explanation:

answer: 800

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
