A baseball player throws a baseball directly upward into the air. The height of the ball is given by the equation y= -4.9x^2 + 89.5x + 1.75 where y is the height in meters and x is the time in seconds. Is this equation a reasonable model for the balls trajectory explain ? a= no the equation does not match the model for projectile motion

b= yes the equation matches the model for the projectile so it is a reasonable model for the balls trajectory

c= no the initial height is 1.75 meters which is much taller then any person

d= no the initial velocity would be 89.5 meters per second this is approximately 200 miles per hour, which is faster than any human can throw a baseball

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.
