How do you solve this?
Answers
x² - 16 = 0
+ 16 +16
x² = 16
Take square root
Remember when you take the square root of a perfect square you get two values. +ve and -ve
x = -4
x = 4
because (-4)² = 16
( 4)² = 16

Step-by-step explanation:
Given that,
The estate is estimated as 8in across and the actual measure across is 500 ft
Then, this shows that
8in represent 500ft on scale
Then, divide both sides by 8
1in will represent 62.5ft
Now, we are told that the height of the stadium is estimated as 2inches, so what is the real value in ft
Since, 1in =62.5ft
Then, multiply both sides by 2
Therefore, 2in=125ft.
The height of the stadium in feet is 125ft

Answer and Step-by-step explanation:
The parent function, f(x) = |x|, has no transformations applied to it.
When the number is with the x, it translates the graph horizontally. <->
When the number is outside of the absolute box, it translates the graph vertically. ^ V
When the number is multiply the absolute box on the outside with the x inside, it scales the graph.
So, first lets apply the translations of horizontal and vertical shift.
The graph translated 1 units downwards.
The graph translates 2 units to the right.
g(x) = |x - 2| - 1
We subtract the 2 because that makes it go right, while if we added it would go left.
Now for the scale.
The lines have a slope of , so that is what we are multiplying.
g(x) = |x - 2| - 1
^That is your transformed function.

Explanation
When looking for the quartiles of any data, you first arrange the data in ascending order.
The lower quartile of a data is the median of the lower half of that data.
The data in the question is already in ascending order.
The lower quartile is the value that is in (1/4)th position.
1/ 4 × 11 = 2.75th position.
This digit is between 2nd position and 3rd position but nearer 3rd position.
0, 1, 3, 3, 4, 4, 4, 5, 6, 6, 8.
So we take the lower quartile to be in the 3rd position.
