marysya [2.9K]

Answer:

$\huge\boxed{(2;\ 4)}$

Step-by-step explanation:

We have

$y>-x^2+5$

Put the coordinates of the given points and check the inequality:

For (0; 5) → x = 0; y = 5

$5>-0^2+5\\5>0+5\\5>5\qquad\bold{FALSE}$

For (2; 4) → x = 2, y = 4

$4>-2^2+5\\4>-4+5\\4>1\qquad\bold{TRUE}$

For (1; 3) → x = 1, y = 3

$3>1^2+5\\3>1+5\\3>6\qquad\bold{FALSE}$

A dinner platter is in the shape of a regular decagon the platter has an area of 161 in.² and a side length of 4.6 inches what's

cupoosta [38]

Number of sides= 10
Side length= 4.6 ( or in this case base)

161 sq inches / 10 = 16.1 area of triangle.

Area of triangle =(b<span>ase * </span>height)/2

16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)

32.2=4.6*h
divid 32.2 by 4.6

<span>7 is the height of the triangle</span>
