Aloaf of bread is removed from an oven and is left sitting in the kitchen to cool. its temperature t minutes after being removed from the oven is given by the equation t(t) = 103e-0.0182t73. find the temperature of the kitchen (assuming the temperature remains constant), the initial temperature of the bread when it is removed from the oven, and the temperature of the loaf of bread after 90 minutes.

(a). 73° C.

(b). 176° C.

(c). 93.02°C.

In the question,

We have been given an equation,

(a).

We need to find the temperature of the kitchen,

So,

Time, t → ∞

On putting the value of t as infinite in the equation we get,

Therefore, the temperature of the Kitchen is 73° C.

(b).

The initial temperature of the bread when it is removed from the oven is at, t = 0 s

So,

On putting the value of t = 0, we get,

Therefore, the initial temperature of the bread is 176° C.

(c).

On putting the value of t = 90 minutes, we get,

Therefore, the temperature of the bread after 90 minutes is 93.02°C.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
