Alexa is constructing a circle inscribed in a triangle. she has partially completed the construction, as shown below. what should be her next step in the construction? triangle abc is shown with arc markings on side ab and bc and two intersecting arc markings across from angle b. there is a line drawn from angle b through the two intersecting arc markings. connect vertex b to the arc marking to complete the angle bisector use the compass to find the angle bisector for angle a connect three arc markings together to form the triangle use the arc markings to determine the radius to construct the circle

Abee with velocity vector r'(t) starts out at (5, −5, −3) at t = 0 and flies around for 5 seconds. where is the bee located at time t = 5 if 5 0 r'(u)du = 0?

The surface area of the triangular prism is .
