Suppose that x and y very inversely. X equals -4/15 when y =-105. Write a function that models the inverse variation then find Y

dezoksy [38]

Xy = k
(-4/15)(-105) = k
28 = k
xy = 28
10y = 28
Divide both sides by 10
y = 2.8

Answer:

3. aₙ = -9n +7

4. d = -2.4

5. a₆ = 45

6. aₙ = 133 + 4n

Step-by-step explanation:

Question 3.

a₁ = -2; aₙ = aₙ₋₁ - 9

The explicit rule for an arithmetic sequence is

aₙ = a₁ + d(n -1 )

d = aₙ - aₙ₋₁

aₙ = aₙ₋₁ - 9 Subtract aₙ₋₁ from each side

aₙ - aₙ₋₁ = -9

d = -9

For this sequence,

aₙ = -2 – 9(n - 1) Remove parentheses

aₙ = -2 - 9n + 9 Combine like terms

aₙ = -9n + 7

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

Question 4

d = aₙ - aₙ₋₁

a₂ - a₁ = 6.2 – 8.6 = -2.4

a₃ - a₂ = 3.8 – 6.2 = -2.4, etc.

The common difference is

d = -2.4

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

Question 5

aₙ = 8n – 3 Substitute the value of n

a₆ = 8×6 – 3

a₆ = 48 - 3

a₆ = 45

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

Question 6

a₁ = 137; d = 4

aₙ = a₁ + d(n -1 )

aₙ = 137 + 4(n -1 )

aₙ = 137 + 4n -4

aₙ = 133 + 4n
