For each sequence find the first four terms and the tenth term 3n-4

antoniya [11.8K]

Answer:

= 1, 2, 5, 8 and 26

Step-by-step explanation:

To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula

a₁ = 3(1) - 4 = 3 - 4 = - 1

a₂ = 3(2) - 4 = 6 - 4 = 2

a₃ = 3(3) - 4 = 9 - 4 = 5

a₄ = 3(4) - 4 = 12 - 4 = 8

The first 4 terms are

- 1, 2, 5, 8

Substitute n = 10

a₁₀ = 3(10) - 4 = 30 - 4 = 26

What value of n makes the equation 4(0.5n -3) = n-0.25 (12 - 8n) true

jek_recluse [69]

Answer:

n = -9

Step-by-step explanation:

4(0.5n -3) = n-0.25 (12 - 8n)

First use the Distributive Law to expand the parentheses:-

2n - 12 = n - 3 + 2n

2n - 12 = 3n - 3

Subtract 2n from both sides:-

-12 = n - 3

Add 3 to both sides:-

-9 = n

A race pilot's average rate of speed over a 720-mile course is inversely proportional to the time in minutes t the pilot takes t

alexira [117]

If d = rt, Then r = d/t
avg speed = 720/t

Therefore after subtracting penalty points, the function for score is:
$s = \frac{720}{t} - p$

For part 2 i will attach a picture.

Part 3)
Set s = 3 and solve for t
$\frac{720}{t} - 2 = 3$
$720 = 5t$
$t =144$
