Answer:
a) Q(-2,1) is false
b) Q(-5,2) is false
c)Q(3,8) is true
d)Q(9,10) is true
Step-by-step explanation:
Given data is is predicate that then . where are rational numbers.
a)
when
Here that is satisfied. Then
this is wrong. since
That is Thus is false.
b)
Assume .
That is
Here that is this condition is satisfied.
Then
this is not true. since .
This is similar to the truth value of part (a).
Since in both satisfied and for both the points.
c)
if that is and
Here this satisfies the condition .
Then
This also satisfies the condition .
Hence exists and it is true.
d)
Assume
Here satisfies the condition
Then
satisfies the condition .
Thus, point exists and it is true. This satisfies the same values as in part (c)

<span>All three angles are equal and their sum is 180. </span>
<span>3 (3x-12) = 180 </span>
<span>9x -36 = 180 </span>
<span>9x = 180+36 </span>
<span>9x = 216 </span>
<span>x = 216/ 9 = 24 </span>

<span>Area of an equilateral triangle = (sqrt(3)/4 ) s^2 = 270.633 </span>
<span>s^2 = 270.633 / [ sqrt(3) /4] </span>
<span>s^2 = (4)(270.633) / sqrt(3) </span>
<span>s^2 = 625 </span>
<span>s = 25 (side) </span>
<span>Follow the procedure in the link: we don't need the altitude. </span>
<span>r = 25/sqrt(3) =14.43

I think that would be 1 by 3 feet
