Question

A science experiment requires the decrease of temperature from 36 degree Celsius at the rate of 4 degree Celsius every hour. what will be the temperature after 10 hours​

Answer 1

Answer: 0° C

Step-by-step explanation:

A science experiment requires the decrease of temperature from 36 degree Celsius at the rate of 4 degree Celsius every hour.

We can easily convert this statement to ARITHMETIC PROGRESSION in which it is given the following data.

GIVEN

a = 36                                   {First Term}

d = -4                                    {Common Difference}

n = 10                                   {Number of terms}

SOLUTION

an = a + (n-1)d

⇒ an = 36 + (10-1)-4

⇒ an = 36+ (-36)

⇒an = 0 (ANS)

Therefore, after 10 hours the temperature becomes 0° C.
