<h2>Answer:</h2>

Option:A is the correct answer.

The quadratic regression equation for the data set is:

A. $y=0.056x^2+1.278x-0.886$

<h2>Step-by-step explanation:</h2>

We are given a set of data value as:

x y

3 3.45

5 6.9

6 8.79

8 12.91

10 17.48

12 22.49

15 30.85

On plotting these points on a scatter plot we see that the line that best fits these data points is a parabola i.e. the equation is a equation of a quadratic function.

The equation of the line of best fit is:

$y=0.056x^2+1.278x-0.886$

Solve the quadratic equation by taking the square root of (x+5)^2=16

Liula [17]

Hi okay i’m gonna write the explanation i hope you give me a brilliant if you think I’m deserving it thank you

(x-5)2=16

The first step you can take to solve this quadratic is to take the square root of both sides of the equation.

√[(x-5)2]=√(16)

When you take the square root of a term that is square it equals what is inside the parentheses.

So on the left side, you have x-5

On the right side, you are what we call "forcing" the square root. When this happens, you need to put ±. Why? Good question. When you square a negative number it positive; when you square a positive number it is also positive.

The √16 = ±4

So now we have;
x-5=±4

What do you do with that?
You make two separate equations.

x-5=4 and x-5=-4
x=9 x=1

Let's check our answers

x=9

(x-5)2=16
(9-5)2=16
42=16
16=16 it checks

x=1

(x-5)2=16
(1-5)2=16
(-4)2=16
16=16 it also checks

ANSWER: x=9 and x=1
