Write the equation of a parabola with focus of (1,-2) and vertex at (9,-2). a y + 2)2 = 327-5)
c (2+ 2)2 =-32[y-9)
b. (+372 =-307-5)
d (x+ 2)= 32(y-9
Please select the best answer from the choices provided

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 think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
