Find the quadratic function that fits curve below. Select the correct answer.
raketka [301]
<h2>Hello!</h2>

The answer is:

The quadratic function that fits the given picture is:

y=-3x^{2}+13x-5

<h2>Why?</h2>

We can solve the problem and find the correct function that fits the curve below by finding which function intercepts the y-axis at -5 (we can see it from the picture), also, we need to look for a function that represents a parabola opening upwards. We need to remember that when a parabola is opening upwards, its quadratic term coefficient is negative.

So, we can see that from the given functions, the only function that represents a parabola opening upwards and its y-intercept is located at y equal to -5 is the second option:

y=-3x^{2}+13x-5

We have that :

a=-3(negative)\\b=13\\c=-5(y-intercept)

We can see that the quadratic term (a) is negative, and the quadratic function intercepts the y-axis at y equal to -5.

Hence, the answer is:

The quadratic function that fits the given picture is:

y=-3x^{2}+13x-5

Have a nice day!

Note: I have attached a picture for better understanding.

What is the distance between the points (-4,2) and (3,-5)
34kurt

Answer:

7√2 units

Step-by-step explanation:

The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

\sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} }

Here, x1=-4 and y1=2

x2=3 and y2=-5

\sqrt{ {(3  - ( -  4))}^{2}  +  {( - 5 - 2)}^{2} }

\sqrt{ {(3 + 4)}^{2}  +  {( - 7)}^{2} }

\sqrt{ {(7)}^{2}  +  {( - 7)}^{2} }

\sqrt{49 + 49}  = 7 \sqrt{2}
