75 degrees because we are asking what is -114-(-39) when we open the parenthesis we get -114+39 which is -75 so, we know -39 is 75 degrees warmer than -114
Answer:
okj
Step-by-step explanation:
t=D/r
Divide r by both sides to get t by itself.
0.925 or 92.5%
y=a(1-b)^x
decay factor is 1-b <- and the part we care about
b is 7.5%=0.075
1-0.075
=0.925
I'm a little rusty on exponential rates, but I hope this helps!
