A spring attached to the ceiling is stretched 2.45 meters by a four kilogram mass. The mass is set into motion in a medium that imparts a damping force numerically equal to 16 times the velocity. If the mass is pulled down two centimeters and released, the solution for the position isa. x = 0.02e^2t - 0.04te^2t b. x =2e^-2t + 4te^-2t c. x = 0.02e^-2t + 0.04te^-2t d. x = e^-2t sint e. x = 0.02e^-2t cost

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
