The Baltimore Zoo feeds their elephants a combination of fruit and grass. The zookeeper would like to create a model to represen
Anika [276]

A function can be represented on a table and on a graph.

The models of the linear relationship between f(x) and x are:

\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}

The given parameters are:

\mathbf{Start = 22}

\mathbf{Additional = 30}

So, the function that models the linear relationship is:

\mathbf{f(x) = Start + Additional \times x}

Substitute known values

\mathbf{f(x) = 22 + 30 \times x}

Evaluate all products

\mathbf{f(x) = 22 + 30x}

Rewrite as:

\mathbf{f(x) = 30x + 22}

By comparing the above function to the list of options, we have the true options to be:

\mathbf{A.\ f(x) = 30x + 22}\\\mathbf{C.\ The\ table}\\\mathbf{F.\ The\ graph}

Answer:

  $6307.95

Step-by-step explanation:

The compound interest formula can help with that.

  A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.

  P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95

Momba needs to deposit $6307.95 today to have $8000 in 6 years.

Please answer the question below ​
Hatshy [7]

Answer:

g

Step-by-step explanation:

The maximum value occurs at gradient 0 (the stationary point).

In f this has a value (y) of 6.

In the equation example we have to differentiate:

dg(x)/dx = -x + 4

Gradient is 0 so 4 - x = 0 so x = 4

Plug g(4)=our maximum=-(1/2)4^2 + 4(4) + 3 = -8 + 16 + 3 = 11

11 > 6 so g has greater maximum.
