For this case we have the following function:
 f(x) = 4x + 7 

 <span>Deriving t</span><span>he function we have:
 </span>f '(x) = 4 &#10;
 We now evaluate the function for the value of x = 5.
 We have then:
 f '(5) = 4 &#10;
 Answer:
 
the derivative of f(x) = 4x + 7 at x = 5 is:

Helen [10]

Answer:

7n - 2 = 19

Step-by-step explanation:

7 times a number is 7n.

7 times a number, decreased by 2, is 7n - 2.

How do you do this? please help me
Anastaziya [24]

Answer:

f = 10, g = 4.8 cm

Step-by-step explanation:

Area of ABCE = 60 cm²

Area of ABCD = 48 cm²

So,

Area of ADE = 60-48

=> 12 cm²

Area of ADE = \frac{1}{2} (Base)(Height)

<u><em>Where Area = 12 cm², Base = 4 cm</em></u>

12 = \frac{1}{2}(4)(Height)

Height = 12-2

Height = 10 cm

Where Height is AD

So, AD = 10 cm

Also, <u><em>AD is parallel and equal to BC</em></u>(f)<u><em></em></u>

So,

f = 10 cm

<u><em>Now, Finding g</em></u>

Area of ABCD = Base * Height

<u><em>Where Area = 48 cm², Base = 10 cm</em></u>

48 = 10 * Height

Height = 48/10

Height = 4.8 cm

Whereas, Height is g

So, g = 4.8 cm

Describe the transformations necessary to get from the graph of the parent function f(x)=x? to the
VashaNatasha [74]

Answer:

 translate the graph 5 units left and down 2 units

Step-by-step explanation:

To translate the function f(x) by an amount h units right and k units up, make the transformation ...

 g(x) = f(x -h) +k

Comparing this to your equation,

 g(x) = f(x +5) -2

we see that the translation is h = -5, k = -2.

The graph of f(x) is translated 5 units left and 2 units down to make the graph of g(x).
