Answer
3
Step-by-step explanation:
h(-6)=-(-6)-3
h(-6)=6-3
h(-6)=3
Discriminant = b^2 - 4ac
a = 4
b = 16
c = 16
16^2 - 4(4 x 16)
256 - (4x64)
256 - 256 = 0
Therefore it only has one root
We know that
a1----------> <span>grains of rice in the first square
a1=2
n------------> space ubication
the expressions is
an=a1</span>^n----------> an=2<span>^n
for the </span><span>the tenth space n=10
</span>an=2^10---------> an=1024 grains of rice
the answer is
1024 grains of rice
1) A 2) C 3) D
These are the answers
