Answer:
k = anything that is less than 2, so 1, 0, -1, -2, -3, -3 1/4, etc.

Answer:
x = 64
Step-by-step explanation:
looking at the other sides, you find that each side had just been doubled.
Answer:
2.25π square inches [or 7.07 sq. in. rounded to 2 decimal places]
Step-by-step explanation:
The largest circle inscribed in a square would have DIAMETER EQUAL TO THE SIDE LENGTH OF THE SQUARE.
Since diameter is double of radius, we can find the radius to be:
diameter = 3 [side length of square]
radius = 3/2 = 1.5 inches
The area of a circle is πr^2
THus, the largest circle area = πr^2 = π(1.5)^2 = π(2.25) = 2.25π square inches
12.7
Using the Pythagorean theorem, you can easily calculate the length of BC.
So:
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So:
BC/sin(55) = CD/sin(90)
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD
10.39230485/0.819152044 = CD
12.68666167 = CD
12.7 = CD
Answer: C
