...**Math** Problem a) I constructed the first linear function based on the municipal solid waste data for 1970 and 1997 and the second linear function based on the data for 1980 and 1997. A dependent variable is the annual production of municipal solid waste in million tons. An independent variable is the number of years after 1960.
Based on the municipal solid waste data from the graph, I received such numbers for independent and dependent variables for the models.

Model 1:
121 = a + b*10
217 = a + b*37
The solution is a=85.4, b=3.56. Therefore, the first linear function is:

...Derivatives of sine functions Investigate the derivative of the function Figure Graph of function and for Figure shows the graph of function (red curve) and it derivative (gradient) (green curve). From graph it can be seen that the gradient of the function behaves similarly as original function, however it shifts left side by (or shift right side by).
= or
From above, it is obvious that the graphs of the sine and it derivative cosine functions are sinusoids of different phases1. The derivative is also a sine function with a phase-shift of (or).
Conjecture: The graphs of the sine function, and its derivative cosine function, are sinusoids of different phases i.e. the derivative is also a sine function with a phase-shift... of sine...

2) For the reaction: 2AgN03 + BaCl2 ► 2AgCl + Ba(N03)2
If a solution containing 41.6g of AgN03 is mixed with a solution that contains 35.4g BaCl2:
a) which reagent is limiting and which in excess?
Ans. 2AgN03 + BaCl2 ► 2AgCl + Ba(N03)2
The molar ratio between AgNO3 and BaCl2 is 2:1
Mr of AgNO3 = 169.87
Mr of BaCl2 = 208.33
Given mass of AgNO3= 41.6g
Given mass of BaCl2= 35.4 g
Moles = Mass/ Mr
Moles of AgNO3 present in given mass= 41.6/169.87= 0.24489 moles
Moles of BaCl2 present in given mass= 35.4/208.33= 0.1699
