6. Do the following tasks using Mathematica. y²dA, where R is the region bounded by the curves xy = 1 , xy = 2 , R x * y ^ 2 = 1 and x * y ^ 2 = 2 Transform R into uv plane by making an appropriate change of variables in order to find the integral. (a) Plot R in both ry and uv planes. (b) Find the Jacobian of the transformation (c) Evaluate the integral using the transformation

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
