Answer:
(x - 5)^2 + y^2 = 225/4,
or you could write it as (x - 5)^2 + y^2 = 56.25.
Step-by-step explanation:
The factor form is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and r = the radius.
So we have:
(x - 5)^2 + (y - 0)^2 = r^2
As the point (-1, 9/2) is on the line:
(-1 - 5)^2 + (9/2)^2 = r^2
r^2 = 36 + 81/4
r^2 = 225/4.
So substituting for r^2:
(x - 5)^2 + (y - 0)^2 = 225/4
(x - 5)^2 + y^2 = 225/4 is the standard form.
Answer:
t+3r
Step-by-step explanation:
This is a one step solution
All you do is add like terms
In this case the only like terms are the varibles r
2r+(t+r)
so if you add all of the rs together there would be 3rs
So the rest of the problem would continue as normal while bringing the 3r to the end
t+3r

Answer:
c .3.3
Step-by-step explanation:
pH is the negative log of the molar hydrogen ion concentration.The equation to calculate pH is;
pH = -log10[H+]
pH = -log10(5.0 x 10-4)
pH = 3.30
1-(1/5)= 4/5 or 28/35 if you multiply top and bottom by 5
