Given the function f(x) = −3x3 + 9x2 − 2x + 3, what part of the function indicates that the left end starts at the top of the gr
shutvik [7]

Answer: The correct option is, The coefficient of the first term.

Step-by-step explanation:

The given function is,

f(x)=-3x^3+9x^2-2x+3

End behavior of the polynomial function : It is defined as the graph of f(x) as x approaches +\infty and -\infty.

The end behavior of the graph depends on the leading coefficient and degree of the polynomial.

As, the degree of the polynomial is '3'. So, the leading coefficient will determine the structure of the graph.

Therefore, the coefficient of the first term will indicate that the left end starts at the top of the graph.

The graph is also shown below.

In a memory​ experiment, Alice is able to memorize words at a rate given by m '(t)= - 0.009t^2 + 0.6t. In the same memory​ exper
White raven [17]

Answer:

1) Ben, 2) \Delta = 2, 3) \dot m = 2.7, 4) \dot M = 2.9

Step-by-step explanation:

1) Ben has a higher rate of memorization, since the coefficient of the second power is lesser than the one from Alice.

2) The number of words can be estimated by integrating the function:

Alice

\Delta m = -0.003\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}

\Delta m = 27

Ben

\Delta M = -0.001\cdot (10\,min)^{3} + 0.3\cdot (10\,min)^{2}

\Delta M = 29

\Delta = \Delta M - \Delta m

\Delta = 2

3) The average amount of words per minute is:

\dot m = \frac{27}{10}

\dot m = 2.7

4) The average amount of words per minute is:

\dot M = \frac{29}{10}

\dot M = 2.9

Find the value of two numbers if their sum is 19 and and their difference is 5
sergij07 [2.7K]

Answer:

7 and 12

Step-by-step explanation:

x - y = 5

y = (5+x)

x+ (5+x) = 19

2x +5 = 19

2x = 14

x = 7

           19-7 = 12

12 +7  = 19

12-7 = 5
