The answer is AB = BC = 4√2

Answer:

AB = BC = 4\sqrt{2}

Step-by-step explanation:

This is a 45-45-90 triangle (right isosceles). This means that the side ratio is

1:1:\sqrt{2}, where AC is sqrt 2, and AB and BC are 1. Now, we need to plug this into our ratio. If sqrt 2 is 8, then 1 is x.

8/\sqrt{2} = x/1 = x

x = 8/\sqrt{2} = 4\sqrt{2} (rationalized)

AB and BC are both 4 * sqrt 2

Given the scatter plot, choose the function that best fits the data.
geniusboy [140]

Considering the scatter plot, the function that best fits the data is given by:

f(x) = 3x².

<h3>What is the function that best fits the data?</h3>

To find the function that best fits the data, we have to look at the scatter plot, which gives a series of points (x,y).

We have that:

  • When x increases, y also increases, hence the function is increasing, which removes the option f(x) = -3x.
  • The increase looks "faster" than a linear increase, hence a quadratic model should be used, thus removing option f(x) = 3x.

Hence the function that best fits the data is given by:

f(x) = 3x².
