A(1 ) = -2 a(n) = a(n - 1) - 5 Find the 4 ^ (th) term in the sequence .

Mathematics
1 answer:
RideAnS [48]3 years ago
7 0

Answer:

  -17

Step-by-step explanation:

Each term in the sequence is 5 less than the one before, so the first 4 terms are ...

  -2, -7, -12, -17

The 4th term of the sequence is -17.

__

The general term (an) of the sequence can be written as ...

  an = a1 +d(n -1)

where a1 is the first term and d is the common difference. Here, those are ...

  a1 = -2, d = -5

so the general term is ...

  an = -2 -5(n -1)

We can use this to find the 4th term:

  a4 = -2 -5(4 -3)

  a4 = -17

When P it was $55 how many units well the profit maximizing firm supply to the market a 30 be 40 C 50 D 16
topjm [15]

Answer:

C. 50

Step-by-step explanation:

Here we have to look at the given graph and find the answer.

The vertical axis represents the price and cost per unit. That is represented by P.

The horizontal axis represents the units of output, that is represented by q.

We need to find the number of units when p = $55.

By look at the graph of the curve MC, when P = $55, the number of units is 50.

Therefore, the answer is C. 50.

Hope this will helpful to understand the concept.

Thank you.

Which of the following is a composite number that is divisible by both 2 and 3? A. 540 B. 351 C. 765 D. 1261
Kazeer [188]

The answer is A. 540

540 divided by 2 = 270

540 divided by 3 = 180

The number 540 is also composite, which is required in your answer.

The other numbers do not end in 0,2,4,6 or 8, which is required to be divided evenly by 2. And only answer choices A. B. and C. can be evenly divided by 3.

18 positive integers and 13 negative integers are multiplied.
Galina-37 [17]

Using multiplication rules, it is found that the result of the multiplication will be a negative number.

<h3>What are multiplication rules?</h3>

  • When two numbers of the same signal are multiplied, the result is positive.
  • Hence, when an even number of negative numbers are multiplied, the result is positive. If an odd number is multiplied, the result is negative.

Hence, in this problem we have that:

  • The result of the multiplication of the 13 negative integers is negative.
  • The result of the multiplication of the 18 positive integers is positive.
  • The multiplication of both results is the multiplication of a negative by a positive, hence it is negative.
