Average rate of change of the function: 
Step-by-step explanation:
The average rate of change of a function f(x) can be calculated as:
where:
are the x-values of the interval taken into account to evaluate the rate of change of the function
are the values of the function at those points
In this problem, we have:
The function is 
, so
So, the average rate of change in this interval is:

Answer:
Step-by-step explanation:
- <em>Assuming copper sulfate has same density as water</em>
<u>Chemical to water ratio as per given is:</u>
- 250 kg : 1000 liter = 1 kg : 4 liter
Lab solution is 350 ml
<u>Converting to same ratio as above:</u>
350/(1 + 4) = 70 ml
- 70 ml : 280 ml = 70 g : 180 ml = 0.07 kg : 180 ml
Answer is 0.07 kg
Complementary angles add up to 90°. The complement of a 27° angle is 90°-27°= 63°.
Supplementary angles add up to 180°. The supplement of a 27° angle is 180°-27°=153°
