25. according to the line graph below, between which two consecutive years was there the greatest change in the number of 3-d movies released? number of 3-d movies released by year number of 3-d movies released 2003 2004 2005 2006 2007 2008 2009 2010 2011 yea a. 2003-2004 b. 2008-2009 c. 2009-2010 d. 2010-2011

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

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
