Answer:
28.46
Step-by-step explanation:
Use a^2+b^2=c^2 to find height
Then use the area formula bh/2 to find area :))
Subtract 1 because the number is going down by one
The answer should be X>10
The answer would be -2k -30
Answer:
converges
Step-by-step explanation:
the individual fraction terms go against 0 with larger and larger n.
and therefore the sum converges.
the numerator of the fractions stays constant (4) but the denominator (bottom) of the fraction increases more and more with investing n (it does not matter that it uses roots, compared to the constant 4 they too grow immensely large with large n).
the limit of a/infinity is defined as 0.
