the nth term of a sequence is given by an²+bn where a and b are integers the 2nd term of the sequence is 2 4th term of the sequence is 20. find the 6th term of the sequence

Answers

Answer:

54

Step-by-step explanation:

Tn = an²+bn

T2 = a2²+2b

2 = 4a +2b

Multiply all through by 2

4 = 8a +4b

4b = 4-8a

T4 = a4² + 4b

20 = 16a +4b

4b = 20-16a

4-8a = 20-16a

16a -8a = 20-4

8a = 16

a = 16/8 = 2

4b = 4-8a = 4-8(2) = 4-16 = -12

b = -12/4 = -3

T6 = a6² + 6b

T6 = 2(36) + 6(-3) = 72 -18 = 54

The carnival also offers two magic shows. The morning show is only 20 minutes and it costs $3.75. For the afternoon show, it is 35 minutes and costs $5.25. Which show would give you more for your money?

Answers

Answer:

35 minutes

Step-by-step explanation:

The carnival offers two magic shows

The morning show is for 20 mintes at $3.75

= 3.75/20

= 0.1875

The afternoon show is for 35 minutes at $5.25

= 5.25/35

= 0.15

Hence you pay a lesser amount for 35 minutes

Answers

Answer:

x = 31.8°

Step-by-step explanation:

Applying the Law of Sines, we have:

[tex] \frac{sin(x)}{12} = \frac{sin(75)}{22} [/tex]

Multiply both sides by 12

[tex] \frac{sin(x)}{12} \times 12 = \frac{sin(75)}{22} \times 12 [/tex]

[tex] sin(x) = \frac{sin(75) \times 12}{22} [/tex]

[tex] sin(x) = 0.5269 [/tex]

[tex] x = sin^{-1}(0.5269) [/tex]

x = 31.8° (nearest tenth)

Are 2.r = 4 and 4x + 5 = 13 equivalent? ​

Answers

Answer:

Yes, they are equivalent.

Step-by-step explanation:

2r = 4, r = 2. We get this because 4/2 = 2.

4x+5 = 13. Subtract 5 from both sides and we'll get  4x=8. Now divide 8/4 = 2.

So we get 2 = 2, which means that the expressions are equivalent.
