Hello,
The question is
<span>"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"
It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4
U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.
Answer C

Divide the stack into halves, if the stacks are equal, they are even. If they aren't, they are odd.
A=x²+4, so 12x²+48=12(x²+4)=12a
the original equation becomes: a²+32=12a,
rearrange into standard form: a²-12a+32=0
the coefficient of the a term is -12.
the constant is 32.
The answer is C. Since the sum is less than seven, we need to subtract a fraction. -6 over three is -2. 7-2 is five
Answer:
60
Step-by-step explanation:
Since the sides are equal, the angles have to be equal
The angles of a triangle add to 180
180/3 = 60
Angle A = 60
