The circle below is centered at the point (3, 1) and has a radius of length 2.
what is its equation?
a. (x - 3)2 + (y-1)2 =
b. (x + 3)2 + (y + 1)2 =
c. (x - 1)2 + (y - 3)2 = 4
d. (x + 1)2 + (y+3)2 =

pi x^2

step-by-step explanation:

pi times x squared

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
