first question what is the starting point?Exponential equation for the black bird: g(x) = 2^x-8 + 1King Pig is located at (11,9)

goblinko [34]

Given the exponential function:

$g(x)=2^{x-8}+1$

The starting point is found when x = 0.

So, let's substitute x by 0.

$\begin{gathered} g(0)=2^{0-8}+1 \\ g(0)=2^{-8}+1 \\ g(0)=0.0039+1 \\ g(0)=1.004 \end{gathered}$

Answer: The starting point is (0, 1.004).

Please help, I am not able to find the answer

Anton [14]

Answer:

Assuming you are asked for the equation of the graph, the answer would be y=|x+2|-1.

Step-by-step explanation:

The parent function for the "V-shape" is y=|x|. This particular function is translated to the left two units and down one. This is shown by adding two to x within the absolute value and subtracting one from the absolute value of x+2, leaving you with y=|x+2|-1. If you plug this equation into desmos online graphing calculator, you will see that the graph is identical to the one given.

A rectangular swimming pool that is 10 ft wide by 16 ft long is surrounded by a cement sidewalk of uniform width. If the area of

Alchen [17]

We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.

The value of x is <span>5 feet. </span>
