An astronaut on the moon throws a baseball upward. The height of the ball in feet is given by the equation y = -2.7t2 + 30t + 65, where t is the number of seconds after the ball was thrown. What is the maximum height obtained by the ball, rounded to the nearest hundredth foot?

Step-by-step explanation:

Answer the questions yourself

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
