Answer 2

SOLUTION

GIVEN

The temperature at the depth in d kilometer is

$\sf{T(d) = 10d + 20}$

TO DETERMINE

The temperature Inside the earth in 10 kilometers

EVALUATION

Here it is given that The temperature at the depth in d kilometer is

$\sf{T(d) = 10d + 20}$

So T is a function of depth ( d )

Now we have to determine the temperature Inside the earth in 10 kilometers

So d = 2

Hence the temperature is given by

$\sf{T(d) = 10d + 20}$

$\implies \sf{T(2) = (10 \times 2) + 20}$

$\implies \sf{T(2) = 20 + 20}$

$\implies \sf{T(2) = 40}$

Hence the temperature Inside the earth in 10 kilometers is 40 unit
