If it is completely impossible to put a contract in writing, which of the following would be the best substitute?
I am Lyosha [343]

Answer:

B

Step-by-step explanation:

Because the the contract will be in verbal form. no matter if it is videotaped or recorded or both a "videoed verbal contract" not just written. so like paper thst is notarized or not this is still the same bc the the same rules apply the contract is still valid. the rest of the options are more like what they call gentlemens agreements which would be the handshake type of thing. and no matter what any agreement someone has to witness the transaction or contract. so definitely the answer is B

Find the formula for the nth term of the sequence: 0,7,18,33,52​
defon

Answer:

t(n) = 2n² + n - 3

Step-by-step explanation:

<u>Given sequence: </u>

  • 0, 7, 18, 33, 52

Find the formula for nth term t(n)

<h3>Solution</h3>

<u>Sequence is neither arithmetic nor geometric, analyzing:</u>

  • 0, 7, 18, 33, 52

<u>First level difference</u>

  • 7, 11, 15, 19

<u>Second level difference</u>

  • 4, 4, 4

<u>As there are two levels, the formula should be in the form of:</u>

  • t(n) = an² + bn + c

<u>Trying the formula with the known terms:</u>

  • t(1) = 0 ⇒ a+b + c= 0
  • t(2) = 4a + 2b + c = 7 ⇒ 3a + b = 7
  • t(3) = 9a + 3b + c = 18 ⇒ 3(3a+b) + c = 18 ⇒ 21 + c = 18 ⇒ c = -3

<u>Going back to previous equations to find remaining coefficients:</u>

  • t(1) ⇒ a+ b = 3 ⇒ t(2) = 2a + (a+b) = 7 ⇒2a + 3 = 7 ⇒ a= 2 ⇒ b = 1

<u>So the formula becomes:</u>

t(n) = 2n² + n - 3
