If ABCD is a kite, then by definition it has two pairs of congruent sides.
Let point C has coordinates (a,b).
Then
Solve the system of equations:
Square these two equations and then subtract:
Substitute b=5 into the first equation:
You get two points (1,5) and (-1,5). Point (-1,5) coincides with point A, so C(1,5).
Answer: correct choice is B.
Answer: 90
90 is a composite number because:
4 x 15 = 90
10 x 9 = 90
A composite number has more than two factors.
Hope this helps!
Answer:
Scientific Notation: 4.88 ×10^7
Standard Form: 4.88 ×10^7
Step-by-step explanation:
6.1×10^(-3) = 0.0061
8×10^9 = 8000000000
0.0061×8000000000 = 48800000
