Find the distance of AB.
kherson [118]

Answer:

3

Step-by-step explanation:

A ( 2, 2 )

( x1, y1 ) = ( 2, 2 )

Here,

x1 = y1 = 2

B ( - 2, - 2 )

( x2, y2 ) = ( - 2, - 2 )

Here,

x2 = y2 = - 2

Distance formula : -

d = √ ( x2 - x1 )² + ( y2 - y1 )²

AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²

= √ ( - 2 )² + ( - 2 )²

= √ 4 + 4

AB = √8

The value of √8 is 2.828.

Roundoff to nearest 10 is 3.

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n
alexgriva [62]
From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
y=a(x-h)^2+k

Thus, the equation of the given graph in vertex form is given by
y=a(x-5)^2+8

Also, recall that the equation of a parabola with roots, p and q, is given by
y=a(x-p)(x-q)

Thus the equation of the given graph can be given by
y=a(x-1)(x-9)

To get the value of a, we equate both equations and solve as follows:
a(x-5)^2+8=a(x-1)(x-9) \\  \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\  \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\  \\ 25a-9a=-8 \\  \\ 16a=-8 \\  \\ a=- \frac{8}{16} =- \frac{1}{2}

Therefore, the <span>function that Lindsay used to create her design is
f(x)=-0.5(x-5)^2+8
</span>
