Setler79 [48]

Answer:

f(x)=\dfrac{9}{5}x+32 converts Celsius to Fahrenheit.

g(x)=\dfrac{5(x-32)}{9} converts Fahrenheit to Celsius.

Step-by-step explanation:

Write given data in the table

\begin{array}{cc}x&f(x)\\^{\circ}\text{C}&^{\circ}\text{F}\\20&68\\30&86\end{array}

Let the expression for the function be

f(x)=ax+b

Note, that this equation is linear equation and it is well-known fact that the Celsius to Fahrenheit dependence is linear.

Substitute corresponding values into this expression:

68=20a+b\\ \\86=30a+b

Subtract these two equations:

86-68=30a-20a\\ \\10a=18\\ \\a=\dfrac{9}{5}

Substitute it into the first equation:

68=20\cdot \dfrac{9}{5}+b\Rightarrow b=68-36=32

So,

f(x)=\dfrac{9}{5}x+32

This is the function which converts Celsius to Fahrenheit.

And function

g(x)=\dfrac{5(x-32)}{9} converts Fahrenheit to Celsius.

I don’t get it it doesn’t make sense
san4es73 [151]

Answer:

Area of A = 32ft

Area of B = 36ft

Step-by-step explanation:

All you need to do to solve is multiply width * length * height.

If you do so,

Area of A = 3 * 2 * 5 1/3

= 6 * 16/3

= 32

Area of B = 6 * 4 * 1 1/2

= 24 * 3/2

= 36

Hope this helps!!

Let me know if I'm wrong or you need help in any other problem!!
