The side of a square is 7 m with a possible error of 0.05 m. Use differentials to approximate the maximum relative error in calculating the area of the square. Remember that the area of a square with side length s is A

Step-by-step explanation:

Given :

Length of the side of a square = 7 m

Possible error = 0.05 m

Area of the square of side s is

Therefore,

or dA = 2s . ds

    dA = 2 x 7 x 0.05

          = 0.7

Therefore, the percentage error is given by :

= 1.4 %

idk bring the function back   im not smart

step-by-step explanation:

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
