Answer:
That will be the Transitive Property
Step-by-step explanation:
To find out the answer we divide 0.09 by 10:

÷10=0.009.
Therefore, 0.09 is 10 times as much as 0.009.
R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
To find the zeros set the factors on the numerator equal to zero and solve
(x - 1) = 0 x = 1
(x + 1) = 0 x = -1
