Which equation represents a circle with the same center as the circle shown but with a radius of 2 units
Leona [35]

Answer:

Option B.

Step-by-step explanation:

Consider the below figure attached with this question.

From the below figure it is clear that the center of the given circle is (4,5).

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

where, (h,k) is center of the circle and r is radius.

We need to find the equation of a circle which represents the same center as the circle shown but with a radius of 2 units.

Substitute h=4, k=5 and r=2 in the above equation.

(x-4)^2+(y-5)^2=(2)^2

(x-4)^2+(y-5)^2=4

The required equation is (x-4)^2+(y-5)^2=4.

Therefore, the correct option is B.

While crossing the Atlantic, sailors spot two mermaids 120° apart on each end of an island that is 6 miles away. How far apart a
True [87]

Answer:

outer edge of the island is 20.8 miles

Step-by-step explanation:

As shown in figure sailor spot two mermaids at point B and C. BC is the outer edge of island. Point A represents sailors

AD=6 miles is perpendicular bisector of BC.

It is clear that

\angle A=120 $^{\circ}$

and

\angle BAD=\angle CAD=60$^{\circ}$

we will find BD and DC

in \triangle BAD

tan 60$^{\circ}$=\frac{BD}{AD}

\sqrt 3=\frac{BD}{6}

BD=6\times \sqrt 3

Similarly, in \triangle CAD

tan 60$^{\circ}$=\frac{CD}{AD}

\sqrt 3=\frac{CD}{6}

CD=6\times \sqrt 3

Therefore outer edge of the island,

BC=BD+CD

BC=6\times \sqrt 3+6\times \sqrt 3

BC=12\times \sqrt 3

BC=12\times 1.73

BC=20.76

BC=20.8 miles
