Chantel drew a picture of her dog on a piece of paper that is 12 centimeters long. She used a copy machine to enlarge her drawin
Georgia [21]

Answer:

a(n)=1.15[a(n-1)]

Step-by-step explanation:

we know that

115\%=115/100=1.15

Let

a0 -----> the length of the original copy

<em>The first copy is equal to</em>

a1=1.15(a0)

<em>The second copy is </em>

a2=1.15[1.15(a0)] or a2=1.15[a1]

<em>The third copy is</em>

a3=1.15{1.15[1.15(a0)]} or a3=1.15[a2]

therefore

A recursive formula will be

a(n)=1.15[a(n-1)]

1. PLEASE HELP. Consider the matrices-
Alex

Answer:

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Step-by-step explanation:

Since Matrix A and Matrix B have the same size, then we can simply perform the operation of subtraction on each position within the matrices to get the resulting subtracted matrix.

A =  [  4  7  ]              B =  [  5  4  ]

      [ -3  8  ]                     [  3  6  ]

      [ -5 -2  ]                    [  -1  8  ]

A - B  =  [ (4 - 5)  (7 - 4) ]

             [ (-3 - 3) (8 - 6) ]

             [ (-5 - -1) (-2 - 8) ]

A - B  =  [  -1  3  ]

             [ -6  2  ]

             [ -4 -10 ]

Cheers.
