Please help! 100points! A sequence is defined recursively by the given formulas. Find the first five terms of the sequence.
DiKsa [7]

Answer:

<u>5, 18, 44, 96, 200</u>

Step-by-step explanation:

<u>Given</u>

  • aₙ = 2(aₙ₋₁ + 4)
  • a₁ = 5

<u>First term</u> : 5

<u>Second term</u> : a₂ = 2(a₁ + 4)

  • a₂ = 2(5 + 4) = 2(9) = 18

<u>Third term</u> : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44

<u>Fourth term</u> : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96

<u>Fifth term</u> : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200

Hence, the first 5 terms of the sequence are :

  • <u>5, 18, 44, 96, 200</u>

dmitriy555 [2]

Answer:

Total temperature change 104.25 f.

Step-by-step explanation:

Average temperature change is calculated by dividing total temperature change by the total hours it took for the change.

We have been given the average temperature change.

We have to multiply average temperature change by the total number of hours it took for the temperature to change we get the total temperature change.

⇒ Total temperature change =  Average temperature change * total hours

                                                = -4.17*25

                                                 =104.25 f

Which of the following ordered pairs represents the solution to the system given below?
tigry1 [53]

Answer:

The solution to the system would be (3, -1)

Step-by-step explanation:

You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.

-5x + 20y = -35

5x + 9y = 6

-----------------

29y = -29

y = -1

Now that we have the value of y, we can plug it into either equation and find the x value.

x - 4y = 7

x - 4(-1) = 7

x + 4 = 7

x = 3
