Newton's law of cooling states that the temperature of an object changes at a rate proportional to the difference between its te

Eva8 [605]

Answer:

Step-by-step explanation:

As per Newton law of cooling we have temperature of a cooling object at time t is given by

T(t) = $T_s + (T_0-T_s) e^{-kt}$

where $T_s = 76: T_0 = 200$

When t=2.5, we have

$T(2.5) = 76+(100-76)e^{-2.5k} =180\\e^{-2.5k} =\frac{104}{24} =4.333\\k=\frac{ln4.333}{-2.5} =-0.5865$

Hence equation is

$T(t) = 76+24e^{-0.5865t}$

Using this we find that

$130=76+24e^{-0.5862t} \\e^{-0.5862t}=54\\t=1.59559$

i.e. At 1.6 seconds the coffee will reach a temperature of 130 degrees

A 36-foot-tall tree casts a 9-foot shadow. How tall is a nearby tree that casts a 14-foot shadow at the same time?

kiruha [24]

Answer:

Proportion states that the two fractions or ratios are equal.

Given the statement: A 36-foot-tall tree casts a 9-foot shadow.

To find the height of the nearby tree that cast a 14 foot shadow at the same time.

Let x be the height of the nearby tree.

By definition of proportion;

$\frac{\text{Height of thetall tree}}{\text{Shadow of the tall tree}} =\frac{\text{Height of the nearby tree}}{\text{Shadow of the nearby tree}}$

Substitute the given values we get;

$\frac{36}{9}=\frac{x}{14}$

Simplify:

$4 = \frac{x}{14}$

Multiply both sides by 14 we get;

$x= 4 \times 14 = 56$ foot.

therefore, the height of the nearby tree is, 56 foot.
