Answer:
Mark drove 4 hours
Mary drove 6 hours
Step-by-step explanation:
Answer:
The correct answer is: A = 1/2 bh V = integral A(x) from [-r, r].
Step-by-step explanation:
x^2 +y^2 = r^2 A = 1/2 bh b = 2y = 2sqrt[r^2 - x^2] so that gives A = 1/2 [ 2sqrt(r^2 - x^2)]h which gives A = sqrt[r^2 - x^2]h
Distance sqrt of (x2-x1)/(y2-y1).
Distance = sqrt of 8/-7
