Determine which equation is written in function form:
Mila [183]

<em>Greetings from Brasil... </em>

A 1st degree function can be written in two ways:

F(X) = AX + B

or

Y = AX + B

note that F(X) = Y

So, looking at the alternatives in the question, only Y = 7X/3 - 8 is equivalent to Y = AX + B, where:

A = 7/3

B = - 8

then

\large{\boldsymbol{\mathbf{Y = \frac{7X}{3}-8\Leftrightarrow Y=AX+B}}}   <em>a function of the 1st degree</em>

answer:

<h2>Y = (7/3)X - 8</h2>

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.
