Amy types out an average speed of 38 words per minute. She has already typed 1450 words of her final paper, which will be more than 4000 words which any quality can be used to solve for X number of minutes to take Amy to finish typing her paper?

its b

Step-by-step explanation:

it's the way of the formation

a) (-3, 4) and radius = 2.

b) 7 cms.

Step-by-step explanation:

x^2+ y^2 + 6x - 8y + 21 = 0

x^2 + 6x + y^2 - 8y = -21

Completing the square on the x and y terms:

(x + 3)^2 - 9 + (y - 4)^2 - 16 = -21

(x + 3)^2 + (y - 4)^2  = -21 + 9 + 16 = 4

a) So the center is (-3, 4) and the radius = sqrt4 = 2.

Ill come back to you later with the second part.

(b) For the point P to be a maximum distance from the origin the line must pass through the center of the circle:

Distance of the center from origin:

= √(-3 - 0)^2 + (4 -0)^2)

= 5.

So the dsitance of P from  the origin is  5 + radius

= 7 cm.
