Ajewelry company prints a hidden watermark on the logo of all its official documents. the watermark is a chord located 0.7 cm. from the center of a circular ring that has a 2.5 cm. radius. what is the length of the chord to the nearest tenth

Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Distance between the center and the chord = 0.7 cm

Radius of the circular ring = 2.5 cm

We need to find length of the chord.

Since it forms a right angle triangle.

So, we will use "Pythagorus theorem":

So, Length of chord is given by

Hence, Option 'B' is correct.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
