the function g(x) Is the graph below resulted from shifting the graph of f(x) down 2 units. If f’(2)=8, what is g’(2)?
Sauron [17]

We know that the graph of g(x) is the result of a shift of 2 units down from f(x).

Then, f(x) and g(x) are related by:

g(x)=f(x)-2

Taking the derivative:

g^{\prime}(x)=f^{\prime}(x)

This is because the derivative of a constant number is 0. Finally, evaluating at x = 2:

\begin{gathered} g^{\prime}(2)=f^{\prime}(2) \\  \\ \therefore g^{\prime}(2)=8 \end{gathered}

The dimensions of a rectangular garden is 3 m by 10 m. When both dimensions are increased by equal amounts, the area of the gard
Ksju [112]

Answer:

5 by 12 m

Step-by-step explanation:

The area for rectangle is LxW

The original area is 3*10, or 30 meters.

When both dimensions are increased, now the area is 60.

We can now inch up slowly to see what works:

3.5 and 10.5=36.75 X

4 and 11=40 X

5 and 12=60 YES!

The new dimensions of the garden are 5 m by 12 m, increased by 2, and the new area is 60 meters^2.
