Answer:
(x - 4)^2 + (y + 1)^2=9
Step-by-step explanation:
The equation of a circle can be written using a kinda of fill-in-the-blank method if you know the coordinates of the center and the radius.
If the center is (h,k) and the radius is r, then fill in those given numbers into:
(x-h)^2 + (y-k)^2 =r^2
The center of your circle is (4, -1).
Fill in 4 for the h, -1 for the k and 3 for the r.
(x-4)^2+(y- -1)^2= 3^2
Simplify.
(x-4)^2+(y+1)^2=9
Answer:
Step-by-step explanation:
For a. the 14.7 represents the pressure that the air puts on you all the time.
For b. the d represents the depth you go under the surface of the water.
For c. we have to solve p(d) when d = 8:
p(8) = 14.7 + 0.445(8) so
p(8) = 14.7 + 3.56 and
p(8) = 18.26 psi

If C is the overall cost and x is greater than 1, the equation would look something like this:
C=6+x
If x is equal to 1
C=6
Answer: step by step down there =)
Step-by-step explanation: First times 2 by 3 then times 2 by 2 ok now you should have 6b and 4b now you subtract 6b and 2 and then add 4b and 12 after you add them you should have 4b and 16b so you answer would be 4b = 16b
