C(h,k) radius(r)
C(2,-3) r=4
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16
therefore, the answer is D
61/100 = .61
.61 = 0.6 + 0.01
Hope that helps :)
Answer:
y = 1x - 3
Step-by-step explanation:
Note that the given line has slope +1.
Any line parallel to this line must also have slope +1.
Apply the slope-intercept form y = mx + b:
Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept
-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is
y = 1x - 3
Answer:
Step-by-step explanation:
(x+4)2-3(x+4)-3=0
2x+8-3x-12-3=0
-1x-4-3=0
-1x-7=0
-1x=7
x=7/-1
x=-7
It's pretty clear what the pattern is - 2^(k-1) * (-1)^(k-1) would work backwards, but we have to work forwards to get lower in this case, so we could start at -3 (as long as we put the k-1 in absolute value to make sure it's not 1/8), so we could write it as ∑ (k=1, goes to 4) 2^(|k-4|)*(-1)^(k-4)
It doesn't matter for k-4 because 1/-1 and 1/1 are the same thing as -1 and 1 respectively
