Answer:
(x + 4)^2 + (y-9)^2 = 121
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius
(x - -4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 121
Answer:
negative infinity to positive infinity
Step-by-step explanation:
The graph keeps going forever on both ends.
For rigt triangle with legs legnth a and b and hypotnuse legnth c
a^2+b^2=c^2
we are given
larger leg is 3 longer than smaller leg
hypotnuse is 6 longer than smaller
find smaller
ok so
first pick a smaller leg
lets say b is smaller
longer leg is 3 more than shorter leg
a is 3 more than b
a=3+b
and
hypontuse is 6 more than shorter
c=6+b
sub 3+b for a and 6+b for c in oroiginal equation'
a^2+b^2=c^2
(3+b)^2+b^2=(6+b)^2
9+6b+b^2+b^2=36+12b+b^2
2b^2+6b^2+9=b^2+12b+36
minus (b^2+12b+36) from both sides
b^2-6b-27=0
factor
(b-9)(b+3)=0
set equal to zero
b-9=0
b=9
b+3=0
b=-3
fasle, legnths cannot be negative
answer is shorter side=9 cm
