Answer:
hello :
Step-by-step explanation:
the area of a circle is : A = π r² r : the radius
A = π (6)² = 36π (ft)² ........( answer : C)
L = 50 because 35 + 95 = 130. 180 - 130 means the missing angle is 50 degrees.
9u means you're multiplying 9 into that vector, both components. Same with the 2v. 9*3 = 27 and 9*-1 = -9, so your new vector u is <27, -9>. Now let's do v. 2* -6 (twice) = -12, so your new v vector is <-12, -12>. Add those together now, first components of each and second components of each. 27 + (-12) = 15; -9+(-12)=-21. So the addition of those gives us a final vector with a displacement of <15, -21>
1.2 minutes per hours is the correct answer
