Answer:
From 2004 onwards, fewer than 38.1% of U.S. voters use punch cards or lever machines
Step-by-step explanation:
The percentage of U.S. voters who use punch cards or lever machines in national elections, in x years after 1994, is given by the following equation:
In which years will fewer than 38.1% of U.S. voters use punch cards or lever machines?
In x years after 1994 onwards.
x is found when P(x) = 38.1.
So
From 2004 onwards, fewer than 38.1% of U.S. voters use punch cards or lever machines
Answer:
$1620
Step-by-step explanation:
70x = 1,134 (100)
70 = 113,400
x = 1,620
Answer:
maximum value y = 30
Step-by-step explanation:
Given
- x² + 10x + 5
To complete the square the coefficient of the x² term must be 1
factor out - 1
= - (x² - 10x) + 5
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 10x
= - (x² + 2(- 5)x + 25 - 25) + 5
= - (x - 5)² + 25 + 5
= - (x - 5)² + 30 ← in vertex form
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Hence vertex = (5, 30)
The max/ min occurs at the vertex
Since a < 0 then vertex is a maximum
Hence maximum value is y = 30
10-20=10so the answer and 10-9=1 so that's the answer
