Cheese sticks were 10. for dollar or 10 cents a piece (10/100 =.10 or 10 cents. now 4 for dollar or ,25 x 100 = 25 cents each (4/100). percent change
.25 - , 10 =.15
,15/,25 = .60
.60 x 100 = 60%
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence
![a(n) = a ({r})^{n - 1}](https://tex.z-dn.net/?f=%20a%28n%29%20%3D%20a%20%28%7Br%7D%29%5E%7Bn%20-%201%7D%20)
where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is
![a(n) = 5( {2})^{n - 1}](https://tex.z-dn.net/?f=a%28n%29%20%3D%205%28%20%7B2%7D%29%5E%7Bn%20-%201%7D%20)

Answer:
x = 5
Step-by-step explanation:
x + 5 =
{Midpoint theorem}
2(x+ 5) = x² - x
2x + 10 = x² - x
x² - x - 2x - 10 = 0
x² - 3x - 10 = 0
x² - 5x + 2x - (5*2) = 0
x(x - 5) + 2(x - 5) = 0
(x -5)(x + 2) = 0
{x + 2 is ignored because measurement could not be in negative value}
x - 5 = 0
x = 5
4/5 = 8/10 = 12/15 = 16/20 = 20/25
Hope it helps
