<em>Step-by-step explanation:</em>
<em></em>
<em>The art museum charges a one-time fee of $8.25 plus $2.25 per month.</em>
<em></em>
<em>So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)</em>
<em></em>
<em>Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.</em>
<em></em>
<em>Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)</em>
<em></em>
<em>So, from both the equations it is clear that for only joining the monthly charges are zero.</em>
<em></em>
<em>So, f(0) = 8.25 and g(0) = 10.75.</em>
<em></em>
<em>Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)</em>

Step-by-step explanation:
The range in the average rate of change in temperature of the substance is from a low temperature of 1 F to a high of -11 F.
<h3>What is a formula for Fahrenheit?</h3>
The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) ;
°F = (9/5 × °C) + 32.
Given function:
f(x)= -6 sin(7/3 x+ 1/6) -5
The function will be maximum at the 7/3 x +1/6= 3π/2
So, the maximum temperature will be
= -6 sin (3π/2) -5
= 6 -5
= 1 F
The function will be minimum at the 7/3 x +1/6= π/2
Therefore, the maximum temperature will be
= -6 sin (π/2) - 5
= -6 -5
= -11 F

This is how proportion is written 7:21=3:9. The colons are sign of division so it can be shown in the terms of fraction as 7/21=3/9 or 1/3=1/3
