The function a = 2.4t – 0.1t2 gives the amount a, in micromilligrams (mmg), of a drug in a patient’s bloodstream t hours after being ingested in tablet form. When is the amount of the drug equal to 8 mmg? (Hint: Multiply the equation you write by 10 before solving.)

step-by-step explanation:

the answer is true.

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
