Question

A- Calculate the value of the error (only) with one decimal place for:

(26+/- 8%) × (20 +/- 4%)

Please enter the answer without +/- sign.

B- Using the rules of significant figures, calculate the summation of A = 59.7 and B = 0.72

C-

Calculate the first derivative of the function at the point x=-1.04. Express the answer with two decimal places.

f(x)=2xe^-x

D- Using the rules of significant figures, calculate the MULTIPLICATION of A = 3.926 and B = 0.47

E- Calculate the value of the error (only) with two decimal places for:  

(8 +/- 0.4) / (2.8 +/- 0.2)

Please enter the answer without +/- sign.

F- Your calculated density of aluminum is d = 2.79 g/cm³. Aluminum’s accepted density is 2.70 g/cm³. The percent error (follow significant figures rules)

G- Using a specific method, your calculated density of aluminum is d1 = 2.65 g/cm³. Using a different method, your calculated density d2 = 2.75 g/cm³. Calculate the percentage difference between the two methods (TWO DECIMAL PLACES).
