A cup of hot coffee has been left to cool in a room with an ambient temperature of 21°C.
ch4aika [34]

Answer:

The temperature of the coffee after 10 minutes will be 21.27°C.

Step-by-step explanation:

The equation representing the elapsed time, <em>m</em>, in minutes, since the coffee was left to cool, and the  temperature of the coffee, <em>T</em>, measured in °C is:

T(m)=21+74.10^{-0.03 m}

Compute the temperature of the coffee after 10 minutes as follows:

T(10)=21+74.10^{-0.03 \times 10}

          =21+0.274824\\=21.274824\\\approx 21.27^{o}\ C

Thus, the temperature of the coffee after 10 minutes will be 21.27°C.

Looking to solve (Ac+b-d)(a^2-c)=
Sunny_sXe [5.5K]

It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.

<h3>How to illustrate the information?</h3>

It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.

In this case, it should be noted that the equation

(ac+b-d)(a² - c) will be solved accordingly. This will be:

(ac+b-d)(a² - c)

Open the parentheses

a³c + ac² + a²b - bc - a²d + cd

Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
