Answer: c
Step-by-step explanation:
Answer:
170°
Step-by-step explanation:
To convert from radians to degrees
degree measure = radian measure × 
, thus
degree = 
×
Cancel π on numerator/denominator and 18/ 180 by 18
degree measure = = 17 × 10 = 170°
Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
