Answer:

( - x - 2)(x - 24)

Step-by-step explanation:

48 + 22x -  {x}^{2}  \\  -  {x}^{2}  + 22x + 48 \\  -  {x}^{2} + 24x - 2x + 48 \\  - x(x  -  24) - 2(x  - 24)  \\ ( - x - 2)(x - 24)

Answer:

(x+2)(24-x)

Step-by-step explanation:

48+22x-x²

= -x²-2x+24x+48

= -x(x+2)+24(x+2)

= (x+2)(24-x)

We use Tan in this case:

Tan=(opposite/adjacent)

Tan(36)=23/x

x=23/Tan(36)

x=31.64 length

Hope it helps!

Given the function g(x) = 6(4)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
Mademuasel [1]

We are given the function:

g(x) = 6 (4)^x

 

Part A.

To get the average rate of change, we use the formula:

average rate of change = [g(x2) – g(x1)] / (x2 – x1)

 

Section A:

average rate of change = [6 (4)^1 – 6 (4)^0] / (1 – 0) = 18

 

Section B:

average rate of change = [6 (4)^3 – 6 (4)^2] / (3 – 2) = 288

 

Part B.

288 / 18 = 16

Therefore the average rate of change of Section B is 16 times greater than in Section A.

 

<span>The average rate of change is greater between x = 2 to x = 3 than between x = 1 and x = 0 because an exponential function's rate of change increases with increasing x (not constant).</span>
