The function y = x 2 – 4x + 8 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence

Alla [95]

Answer:

Exterme Value: $(2,4)$ .

The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.

Step-by-step explanation:

The given function is $y=x^2-4x+8$ .

We add and subtract the square of half the coefficient of x.

$y=x^2-4x+(-2)^2-(-2)^2+8$ .

The first three terms form a perfect quadratic trinomial.

$y=(x-2)^2+4$ .

This function is now written in the form $y=a(x-h)^2+k$ , where (h,k) is the extreme value(vertex).

The extreme value or the vertex is $(2,4)$ .

Interpretation:

The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.

Answer:

36.575

Step-by-step explanation:

you need to find line ab you can do $A^{2} +B^{2} =C^{2}$ for the triangle and get the line you also need to get the squar root of it as it is still squared then devide by 2 to get the rades then times that by pi and there you go you have the area also sorry for spelling I love math not English
