Concept explainers
Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk(*) designates a quantitative problem, for which you should show all your work.
Supernova Betelgeuse. The best current estimate of the distance from Earth to the red supergiant. Betelgeuse is about 600 light-years. If it were to explode as a supernova, it would be one of the brightest stars in the sky. Right now, the brightest star other than the Sun is Sirius, with a luminosity of

Please answer on paper Thank you!arrow_forwardRead each problem carefully. Solve each quadratic equation for the variable(s) specified. Be sure to show all of your work. Explain in two to three sentences what the meaning of the solution(s) are in relation to the problem situation. A rubric has been provided for reference. 1. An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per second (ft./s). The height of the object off the ground is given by the formula h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the -16 object is propelled. The downward negative pull on the object is represented by Solve for t.arrow_forwardbox the finals answers. Provide the necessary explanations for your solutions.
