∛15 ≈ 2.466212...
The best choice appears to be ...
B) 2.46 < ∛15 < 2.47
20^2 = 16^2 +x^2
400= 256+ x^2
x^2 = 400 -256
x = 144^1/2
=12
b. yes
Answer:
The one that belong in the dividend bracket is the volume for A. The one that belongs in the divisor bracket is volume C.
Step-by-step explanation:
That's my explanation on what the answer is supposed to be.
The closed formula for <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)

R - 18 = 50
r = 50 + 18 = 68
Hence Rick is 68 yrs old
