A once-popular children's doll is slowly declining in popularity. the quartic function f (x)equals negative 0.022 x superscript 4 baseline plus 0.457 x cubed minus 2.492 x squared minus 5.279 x plus 87.419 commaf(x)=−0.022x4+0.457x3−2.492x2− 5.279x+87.419, where x is the number of years since 1993, can be used to estimate the number of dolls of this type that were sold (in thousands) during a given year from 1993 to 2003. estimate how many dolls were sold in 19941994.

answer: 590

step-by-step explanation:

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
