Answer:
x=2.4
Step-by-step explanation:
brainliest pls
212°F
147°F
23.2 min
1) Initial temperature for t=0
T(0)=68+144e^(0)=68+144=212°F
2) After 15 min
T(15)=68+144e^(-0.04*15)=68+144e^(-0.6)=147°F
3) 125°F -> t=?
125=68+144e^(-0.04t)
144e^(-0.04t)=125-68=57
e^(-0.04t)=57/144=0.4 you can apply ln on both sides:
-0.04t=ln(0.4) solving you get t=23.3 min
Answer:

I'm not sure but I think, f(s)=-4[x]-3
Answer:

This will give 5 Students each in 12 different equally sized groups

This also shows that students can grouped in equal groups of 12 in 5 places
Step-by-step explanation:
From the question we are told that
60 children in equal sized groups
Generally interpreting
can be mathematically represented as
a)


This will give 5 Students each in 12 different equally sized groups
b)


This also shows that students can grouped in equal groups of 12 in 5 places
