Answer: what following?
Explanation:
Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes can be modeled by the equation t(t)=ts+(t0−ts)e−kt, where ts is the surrounding temperature and k is the substance’s cooling rate. A liquid substance is heated to 80°c. Upon being removed from the heat, it cools to 60°c in 15 min. What is the substance’s cooling rate when the surrounding air temperature is 50°c? round the answer to four decimal places. 0. 0687 0. 0732 0. 0813 0. 872.
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
[tex]T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]T_{s}[/tex] - Final temperature, in degrees Celsius.[tex]T_{o}[/tex] - Initial temperature, in degrees Celsius.[tex]t[/tex] - Time, in minutes.[tex]k[/tex] - Cooling rate, in [tex]\frac{1}{min}[/tex].[tex]T(t)[/tex] - Current temperature, in degrees Celsius.Please notice that substance reaches thermal equilibrium when [tex]T(t) = T_{s}[/tex], that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that [tex]T_{o} = 80\,^{\circ}C[/tex], [tex]t = 15\,min[/tex], [tex]T_{s} = 50\,^{\circ}C[/tex] and [tex]T(15) = 60\,^{\circ}C[/tex], then the cooling rate of the substance is:
[tex]60 = 50 + (80 - 50)\cdot e^{-15\cdot k}[/tex]
[tex]\frac{60-50}{80-50}= e^{-15\cdot k}[/tex]
[tex]\frac{1}{3} = e^{-15\cdot k}[/tex]
[tex]k = -\frac{1}{15}\cdot \ln \frac{1}{3}[/tex]
[tex]k \approx 0.0732[/tex]
The cooling rate of the substance is approximately 0.0732.

Marsman inc's latest eps was p2. 75, its book value per share was p22. 75, it had 280,000 shares outstanding, and its debt ratio was 44%. How much debt was outstanding?.
Based on the EPS and the book value, as well as the shares outstanding, the amount of debt is P5,005,000.
First find the total equity:
= Shares outstanding x Book value per share
= 280,000 x 22.75
= P6,370,000
Use that to find the total assets:
= Total equity / (1 - Debt ratio)
= 6,370,000 / ( 1 - 0.44)
= P11,375,000
The total debt is therefore:
= Total assets - Total equity
= 11,375,000 - 6,370,000
= P5,005,000
In conclusion, the total debt is P5,005,000.

Translate: i am hungry. Yo soy hambre. Yo estoy hambre. Yo tengo hambre. Yo es hambre.
Happy Holidays!
Yo tengo hambre.
Yo = I
Tengo = have (I form)
Hambre = hunger
Even though this literally translates to "I have hunger", this expression is used to say the equivalent "I am hungry".
The correct translation of "I am hungry" in Spanish is: "Yo tengo hambre."
Thus, option (c) is correct.
"Yo soy hambre" is not the correct translation.
In Spanish, "soy" means "am" and "hambre" means "hungry," but they are not used together in this context to mean "I am hungry."
"Yo estoy hambre" is also not the correct translation.
"Estoy" means "am" and "hambre" means "hungry."
However, in Spanish, the correct way to express hunger is by using the phrase "tener hambre."
"Yo tengo hambre" is the correct translation.
"Tengo" means "I have," and "hambre" means "hunger."
So, "Yo tengo hambre" translates directly to "I have hunger," which is the equivalent of "I am hungry" in English.
The phrase "Yo es hambre" is not grammatically correct in Spanish.
Thus, option (c) is correct.

In general, an organism will be more likely to develop phobias of __________.
In general, an organism will be more likely to develop phobias of dangers faced during natural circumstances.
Phobia is an unjustified or pathological fear of situations or circumstances that are not dangerous and that most people do not find bothersome. Fear is a natural reaction or an adaptive experience to situations or objects that imply a real danger.When this fear occurs before natural circumstances that do not pose a real danger, then we find this fear is no longer adaptive is what we call a phobia.
Therefore, we can conclude that an organism will be more likely to develop phobias of dangers faced during natural circumstances.
