Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)
T = 12 min, T o = 80° C, T s = 50 °C, T ( 12 ) = 60° C
60 = 50 + ( 80 - 50 ) · e^(-12k)
10 = 30 · e^(-12k)
e^(-12k) = 0.3333...
ln ( 0.333.. ) = - 12 k
- 12 k = - 1.1
k = ( - 1.1 ) : ( - 12 ) = 0.0916
Answer: D ) 0.0916
