Mathematics
1 answer:
Nikitich [7]3 years ago
8 0

Answer:

Step-by-step explanation:

The third, fifth and sixth expressions (from the top) are NOT polynomials, and the reason in each case is that the expression has one or more negative powers of x in it.

Which polynomial is in standard form?
Romashka-Z-Leto [24]

Answer:

C

Step-by-step explanation:

Standard form is [ ax² + bx + c ]

The exponents and variables determine what comes first.  In [ 11x³ - 6x² + 5x ], we can see that the exponents are going from greatest to least and the last number doesn't have an exponent so it goes last. Essentially we can think of this as sorting each part from greatest to least using exponents -> variables -> number to determine that.

Best of Luck!

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.

Supposef(0) = 2 and 2 ≤ f '(x) ≤ 7for all x in the interval [−5, 5]. determine the greatest and least possible values of f(2).le
IgorC [24]

If the slope of the function is 2, the amount it can change over the interval 0–2 is

... 2×2 = 4 units

If the slope is 7, the amount it can change over the interval 0–2 is

... 2×7 = 14 units


The least possible value of f(2) is 2+4 = 6.

The greatest possible value of f(2) is 2+14 = 16.
