Randy bought a used car for 4,568 plus 6% sales tax. What was the total cost of
the car?

The total cost of the car would be $4842.08.

Step-by-step explanation:

To convert from percent to decimal you divide by 100 and remove the "%" sign. So, 6% would be ".06". Times ".06" by $4,568 to get a tax amount of $274.08. Add $274.08 to $4,568 to get $4842.08.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

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
