Answer:
K-a Positive constant that depends on the area and nature of the surface of the body under consideration.
Step-by-step explanation:
Newtons law cooling describes the rate at which an exposed body changes temperature through radiation which is approximately proportional to the difference between the object’s temperature and its surroundings, provided the difference is small. The formula is given as:
where,T- temperature at time t,
is temperature of the surrounding and k- A Positive constant that depends on the area and nature of the surface of the body under consideration.
Answer:
no real zeros
Step-by-step explanation:
We can use b^2-4ac which is 25-16*29.
We know that is negative meaning there is no real zeros.

Answer:
Step-by-step explanation: Let x be the smaller and y be the largest number.
Since x+y=13, we deduce y=13-x
Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x
Their sum is y+2+2x
And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x
