In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if, applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore difference in past, present, and future tense.) If we are to have peace, we must not encourage the competitive spirit. If we are to make progress,we must encourage the competitive spirit . ∴ We do not have peace and we do not make progress ..

Consider the circle C in the xy-plane given by the equation (x − 2)² + (y − 3)²
=
4. Analytically,
determine an equation that describes the image of this circle after a rotation of R² by 270° about the
point (2, 1). Then, sketch the graph of the circle C as well as the image of C under this isometry in the
coordinate axes below.
