Answer:7.5π

Step-by-step explanation:

Φ=360-90

Φ=270

Radius=r=5

Length of arc=Φ/360 x 2 x π x 5

Length of arc=270/360 x 2 x π x 5

Length of arc=0.75 x 2 x π x 5

Length of arc=7.5π

Simplify. (-2)^-3<br> A.-8<br> B.-1/8<br> C.1/8<br> D.8
DiKsa [7]

ANSWER

{( - 2)}^{ - 3} =- \frac{1}{ 8}

EXPLANATION

We want to simplify;

{( - 2)}^{ - 3}

Recall that,

{a}^{ - m}  =  \frac{1}{ {a}^{m} }

{( - 2)}^{ - 3}  =  \frac{1}{{( - 2)}^{ 3}}

We multiply out to get,

{( - 2)}^{ - 3}  = \frac{1}{{- 2} \times  - 2 \times  - 2}

{( - 2)}^{ - 3}  =  \frac{1}{ - 8}

The correct choice is B.

x = 9/(0.05)

x = 180 inches

Divide by 12 to convert from inches to feet.

180 inches = (180/12) feet = 15 feet
