Answer:
35
Step-by-step explanation:
Multiply each side of ABC by 5 to get the values of PQR
The first x should be 12. The sides are multiplied by 4. To find the missing side multiply the corresponding side by 4. 3x4=12. Another x should equal 63 as the sides are multiplied by 9. Multiply 7x9=63.
Answer:
converge
Step-by-step explanation:
the reason is : the individual terms of the series get smaller and smaller towards 0, and therefore the sum converges to a certain limit.
why do I know that the individual terms get smaller and smaller ?
because the terms are ultimately (with n getting very large the constant factors added constants become irrelevant)
n / (n^(3/2))
as sqrt(n³) = n^(3/2)
and n^(3/2) progresses much faster and stronger than n (or n¹), as 3/2 is larger than 1.
so, the denominator (bottom) of that fraction grows stronger than the numerator (top), and the terms go therefore against 0 with larger and larger n.
Put 15 where n is, then do the arithmetic.
b(n) = 6n . . . . . . . . . . . the formula for the number of bulbs for n chandeliers
b(15) = 6·15 = 90
The appropriate choice is ...
... 90 light bulbs
