In the past, professional baseball was played at the Astrodome in Houston, Texas. The Astrodome has a maximum height of 63.4 m. The height in meters of a baseball t seconds after it is hit straight up in the air with a velocity of 45 m/s is given by h= -9.8t^2+45t+1. Will a baseball hit straight up with this velocity hit the roof of the Astrodome? Use the discriminant to explain your answer.

Type the correct answer in each box. use numerals instead of words. if necessary, use / fir the fraction bar(s). the graph represents the piecewise function: h

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x
