Problem 1

<h3>You are correct. The answer is choice C. </h3>

A sequence is just a list of numbers where the order matters. Something like (1,2,3,4,5) is different from (3,1,2,5,4)

A series is where you add up that list of numbers to get a single value. For instance, the sum of the list (1,2,3) is 1+2+3 = 6. This is basically a partial sum when talking about infinite sequences because the next partial sum would be 1+2+3+4 = 10 and the next partial sum would be 1+2+3+4+5 = 15, and so on.

=======================================================

Problem 2

<h3>Answer: Choice A</h3>

Why is this? Each time we get a partial sum, we're basically forming a new sequence. We're forming a sequence of sums. Going back to the example in problem 1, we had the partial sums (6,10,15). If we keep this process going, we'll have the list of partial sums grow forever and not approach some finite value. Therefore, this series diverges.

If the sums were to slowly get closer to some fixed value, then we would say the series converges.

Answer:

  (b) ... confirm ∠C≅∠E

Step-by-step explanation:

The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE  by AA similarity. That means you want to show any two of the three ...

  • ∠A≅∠A
  • ∠B≅∠D
  • ∠C≅∠E

For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.

Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.

The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.

Yuri [45]

Answer:

61/125 or 0.488

Step-by-step explanation:

Total = 5×5×5 = 125

Numbers with no 4 = 4×4×4 = 64

Atleast one 4= 125-64 = 61

P(atleast one 4) = 61/125 or 0.488

Therefore, we conclude that the Jeff must grow 4 inches in order to ride the roller-coaster.

Step-by-step explanation:

We know that: in order to ride a roller coaster,a rider must be greater than 49 inches tall.Jeff is 45 inches tall.

We have the next  inequalitythats:

x+45>49\\\\x>49-45\\\\x>4\\

Therefore, we conclude that the Jeff must grow  4 inches in order to ride the roller-coaster.
