Step-by-step explanation:

<u>Step 1: Answer the first question</u>

Find the perimeter: $P = (\pi *r)+d$ But... let π be 3.14

$P = (3.14 * \frac{27}{2}) + 27$

$P = 42.39 + 27$

$P = 69.39$

Find the price: $7.25 per foot

$7.25 * 69.39$

$\$ $503.0775$

Answer: $\$ $503.0775$

<u>Step 2: Answer the second question</u>

Find the amount traveled: $P = revolutions*\pi *d$ But... let π be 3.14

$P = 17 * 3.14 * 95$

$P = 53.38 * 95$

$P = 5071.1$

Answer:

1. $503.08

2. 5071

Step-by-step explanation:

1. Perimeter = (pi × r) + d

= (3.14 × 27/2) + 27

= 69.39

Cost: 69.39 × 7.25 = $503.0775

2. 17 × (pi × d)

17 × 3.14 × 95

5071.1 feet

Answer:

My answer would be 9 unit away

Step-by-step explanation:

becuase you can subtract 0 from -9

0 + -9 would equal -9

then 9 - (-9) = 0

so 9 is my answer

Sin(60-theta)sin(60+theta)

ehidna [41]

Step-by-step explanation:

$\sin(60 - \theta) \sin(60 + \theta) \\ = \{ \sin(60) \cos( \theta) - \sin( \theta) \cos(60) \} \{ \sin(60) \cos( \theta) + \cos(60) \sin( \theta) \} \\ = \{ \frac{ \sqrt{3} }{2} \cos( \theta) - \frac{1}{2} \sin( \theta) \} \{ \frac{ \sqrt{3} }{2} \cos( \theta) + \frac{1}{2} \sin( \theta) \} \\ \\$

from difference of two squares:

${ \boxed{(a - b)(a + b) = ( {a}^{2} - {b}^{2} ) }}$

therefore:

$= \{ {( \frac{ \sqrt{3} }{2}) }^{2} { \cos }^{2} \theta \} - \{ {( \frac{ \sqrt{3} }{2} )}^{2} { \sin }^{2} \theta \} \\ \\ = \frac{3}{4} { \cos }^{2} \theta - \frac{3}{4} { \sin}^{2} \theta$
