Use the information provided to write the equation of each circle. Photo attached

alina1380 [7]

Answer:

( x + 4 )^2 + ( y - 15 )^2 = 1; Option A

Step-by-step explanation:

~ Let us apply the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2, provided r ⇒ radius when centered at point ( a, b ) ~

1. If the center is provided to be ( -4, 15 ) we could substitute this value into the circle equation with variables x and y remaining such:

( x - ( - 4 ) )^2 + ( y - 15)^2 = r^2

2. Simplifying this equation, we have: ( x + 4)^2 + ( y - 15 )^2 = r^2

3. Now by point on the circle, it would be a point on the circumference, to be clear in more mathematical terms. So far we have eliminated two options, with two remain - and each of them has either a radius of 1 or 2. If the point on the circle is ( -4, 16 ) that would mean 1 more than 15, which means that with a radius of 1 ⇒ this point will be on the circle.

Answer: ( x + 4 )^2 + ( y - 15 )^2 = 1

Answer:

18/12

Step-by-step explanation:

1/3+2/4+4/6

LCM= 12 so,

(1×4)/12+ (2×3)/12+ (4×2)/12

=(4+6+8)/12

= 18/12

The graph shows distances traveled by two boats.

lisabon 2012 [21]

To find the speed of the boats we will divide the distance by time.

From the graph we finde the boats' speeds as ;

$Boat\quad 1\quad =\quad \frac { 35 }{ 5 } =\quad 7\quad km/h\\ \\ Boat\quad 2\quad =\quad \frac { 35 }{ 7 } =\quad 5\quad km/h$

And for the speed of the third boat, we will also divide the distance by time.

$Boat\quad 3\quad =\quad \frac { 32 }{ 4 } =\quad 8\quad km/h$

As you can see the speed of boat 3 (8 km/h) is more than boat 1 (7 km/h) and boat 2 (5 km/h).

Thus the third boat is faster than both of them.

The answer is B.

You can see the speed of boat 1 and 2 in the picture.
