Answer:
A (5,-3) does not belong
B (-2,4) does not belong
C (0,0) belongs
D (2,1) belongs
E (-5,2.5) does not belong
Step-by-step explanation:
To find the answer, you'll need to know
what is the number in half? If (x,y) is like
10,5 then that will belong.
Answer:
The diagonal is 14sqrt(2) ft
Step-by-step explanation:
The area of a square is given by
A =s^2 where s is the side length
196 = s^2
Take the square root of each side
sqrt(196) =sqrt(s^2)
14 = s
The side length is 14 ft
Now we can use the Pythagorean theorem to find the length of the diagonal
a^2 + b^2 = c^2
The side lengths of the triangle are s = 14, and the diagonal is the hypotenuse
14^2 + 14^2 = c^2
196+196 = c^2
392 = c^2
Take the square root of each side
sqrt(392) = sqrt(c^2)
sqrt(196 *2) = c
We can separate this into two pieces sqrt(ab) = sqrt(a) sqrt(b)
sqrt(196)sqrt(2) =c
14sqrt(2) = c
The diagonal is 14sqrt(2) ft
64 inches is the correct answer. To get it you need to multiply the length times the width.
(this is incorrect. Sorry for the inconvenience)
The answer is 2.2 , you divide 99/45
