circular cardboard with an area between 154 in² and 616 in²
Area of a circle = πr²
154 in² = 3.14 * r² 616 in² = 3.14 * r²
154 in² / 3.14 = r² 616 in² / 3.14 = r²
49 in² = r² 196 in² = r²
√49 in² = √r² √196 in² = √r²
7 = r 14 in = r
Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14
√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2 = 4√2
D) It is irrational and equal to 4 multiplied by the square root of 2.

Point P on the directed line segment from A to B will have x and y coordinates that are two-thirds of the length of the line segment from A to B. (-1,2).
What are coordinates?
Any one of a group of integers that are used to define where a point is on a surface, on a line, or in space. coordinates in terms of latitude and longitude.
It is given that, P is Two-thirds the length of the line segment from A to B and the coordinates of the points are A = (9,-8) B = (-6,7).
We have to find the x- and y- coordinates of point P on the directed line segment from A to B
P is a line that divides the line segment from A to B in half.
AP = (2/3) AB
BP = (1/3) AB
We shall subtract two times as much length from AB as there is to A.
x=(m/m+n)(x₂-x₁)+x₁
y=(m/m+n)(y₂-y₁)+y₁
For m=2 and n=1 the value of x and y is,
x=(2/2+1)(-6-9)+9
x=-1
y=(2/2+1)(7-(-8))+(-8)
y=2
Thus, point P on the directed linesegment from A to B will have x and y coordinates that are two-thirds of the length of the line segment from A to B. (-1,2).
