Answer:
Step-by-step explanation:
Formula
h = k/temp
Givens
h = 4 hours
t = 45 degrees
Solution
3 = k / 45 Multiply both sides by 45
3*45 = k
k = 135
Problem
what happens when h = 4 hours?
h = 4
k = 135
temp = ?
4 = 135 / temp Multiply both sides by temp
4temp = 135 Divide by 4
temp = 135 / 4
temp = 33.75
Note that as the time went up, the temperature came down
<span>1st year value =45$
2nd year value=45+2.80$=47.80$
3rd year value=47.8+2.80$=50.60$
4th year value=50.60+2.80=53.40$
5th year value=53.40+2.80=56.20$
ater 5 years value of share becomes 56.20$
or
share after 5 years= 45+4*2.80=45+11.20=56.20$</span>
