Shelly and Jamie participate in a street relay race. Jamie must run from point B along AB⌢, which represents part of a roundabou
Gwar [14]

Answer:

Jamie must sprint 107 meter to pass Shelly at point A.

Step-by-step explanation:

Circumference of a sector of the circle is represented by,

Circumference = \frac{\theta}{360}(2\pi r)

where θ = central angle subtended at the center by an arc

r = radius of the circle

m(\widehat{AB}) = \frac{123}{360}(2\pi )(50)

           = 34.1667π

           = 107.34 meter

           ≈ 107 meter

Therefore, Jamie must sprint 107 meter to pass Shelly at point A.

NNADVOKAT [17]

Answer:

Step-by-step explanation:

1) <u>B(1, 5)</u>

<u />

<u>Dilation</u>

(1,5) => (2x, 2y)

=> (1 x 2, 5 x 2)

=> (2, 10)

<u>Translation</u>

<u>(</u>2,10) => (x + 5, y - 3)

=> (2 + 5, 10 - 3)

=> (7, 7)

<u><em>B' = (7,7)</em></u>

2) <u>Translation</u>

(1,5) => (x + 5, y - 3)

=> (1 + 5, 5 - 3)

=> (6, 2)

<u>Dilation</u>

(6, 2) => (2x, 2y)

=>  (6 x 2, 2 x 2)

=> (12, 4)

<u><em>B' = (12,4)</em></u>
