Answer:
53.3324
Step-by-step explanation:
given that a thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 40° F.
By Newton law of cooling we have
T(t) = 
where T (t) is temperature at time t,T =surrounding temperature = 40, T0 =70 = initial temperature
After half minute thermometer reads 60° F. Using this we can find k

So equation is

When t=1,
we get

Answer:
3
Step-by-step explanation
4 is made into a fraction by putting it over one like 4/1 then multiply it by
3/4 and get 12/4 which is an improper fraction which is then made into 3 12/4 is equal to 3 holes
Answer: Well u would have to divide first and you would get 1 and what is left over would be the numerator which would be 6 and the denominator would stay the same.
Therefore saying that the answer will be 1 6/8
Step-by-step explanation:
Answer:
(x+5)(x+7)
Step-by-step explanation:
Let's factor x2+12x+35
x2+12x+35
The middle number is 12 and the last number is 35.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 12
Multiply together to get 35
Can you think of the two numbers?
Try 5 and 7:
5+7 = 12
5*7 = 35
Fill in the blanks in
(x+_)(x+_)
with 5 and 7 to get...
(x+5)(x+7)
Answer:
(x+5)(x+7)
