Antoine stands on a balcony and throws a ball to his dog, who is at ground level. the ball's height (in meters above ground), x seconds after Antoine threw it is modeled by : h(x) = -2x to the 2nd + 4x + 16

what is the height of the ball at the time it is thrown? ​

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

i'm not really sure how to answer that

step-by-step explanation:

160 cm
