Rule for 90° clock-wise rotation

(x , y) ⇒ ( y, -x)

So

(6,3) ⇒ ( 3, - 6)

Call the number that Caleb had originally, C

Then Matt had (5/8)C

So

(1/2)C + 55 = (5/8)C + 1/2C subtract (1/2) C from both sides

55 = (5/8)C

55 (8/5) = C

88 = C

The square will have a side = 8 in

The radius of the circle will = 4 in

Each side of the smaller square = 4sqrt (2) in

So....the perimeter of the smaller squar= 4 * 4sqrt (2) = 16*sqrt (2) in

The area of the triangle formed by \(a, b,\) and \(c\) is given by

\(\begin{align*} \frac{1}{2} \|(\mathbf{b} - \mathbf{a}) \times (\mathbf{c} - \mathbf{a})\| &= \frac{1}{2} \|\mathbf{b} \times \mathbf{c} - \mathbf{b} \times \mathbf{a} - \mathbf{a} \times \mathbf{c} + \mathbf{a} \times \mathbf{a}\| \\ &= \frac{1}{2} \|\mathbf{b} \times \mathbf{c} + \mathbf{a} \times \mathbf{b} + \mathbf{c} \times \mathbf{a}\| \\ &= \frac{1}{2} \left\| \begin{pmatrix} -3 \\ -12 \\ 4 \end{pmatrix} \right\| \\ \end{align*}\)

which gives you 13/2 as your final answer.

Total area = 16^2 = 256

Red area = pi (2)^2 = 4pi

Yellow area = pi (4^2 - 2^2) = 12 pi

Blue Area = 256 - pi (4)^2 = 256 - 16pi

1. P(red area) = 4pi/256 = pi/64 ≈

2. P ( yellow area ) = 12 pi / 256 = (3/64) pi

3. If 25 darts were thrown we expect that [ 256 - 16 pi ] / 256 ≈ .80 = about 80% would land in the blue area....so 25 *(.80) ≈ 20 would land in the blue area
