Write an equation for the circle with center(-1,-5) and Radius 4sqrt3

Mathematics

irina [24]3 years ago

Answer:

(x + 1)² + (y + 5)² = 48

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 1, - 5) and r = 4\sqrt{3}, so

(x - (- 1))² + (y - (- 5))² = (4\sqrt{3} )², that is

(x + 1)² + (y + 5)² = 48 ← equation of circle

Jake can carry 61/4 pounds of wood in from the barn. His father can carry 1 5/7 times as much as jake.
BigorU [14]
To answer this item, we are to multiply the given amount of wood that Jake can carry which is given to be 6 1/4 by the number of times his father can which is equal to 1 5/7.                x = (6 1/4)(1 5/7)
                x = 75/7
 Thus, Jake's father can carry 10 5/7 pounds of wood. (I've had this question before btw)

What is the sum of the first 10 terms of the sequence 2, 6, 18,54...?
leonid [27]

Answer:

This is a sequence where you <em>multiply that number 3 times</em>.  For example, 2 x 3 = <em>6</em>.  6 x 3 = <em>18</em>.  18 x 3 = <em>54</em> and so on.  Therefore, <em>multiplying 3 by the number is the Answer.</em>
