What is the approximate percent decrease when a fish count goes down from 850 to 500? The percent decrease is approximately 40%.
Korolek [52]

Answer:

<h2><em>The percent decrease is approximately 40%. </em></h2>

Step-by-step explanation:

Step one:

given data

initial count of fish= 850

final count of fish= 500

Required

% decrease

Step two:

% decrease= final-initial/initial*100

substitute

% decrease= 850-500/850*100

% decrease=350/850*100

% decrease= 0.41*100

% decrease= 40.1%

<em>The percent decrease is approximately 40%. </em>

Suppose f(x) = x2 and g(x) = 4x2. Which statement best compares the graph of g(x) with the graph of f(x)?
Fiesta28 [93]
Given:
f(x) = x²
g(x) = 4x²

Therefore
g(x) = 4f(x)
This means that the value of g(x) is 4 times the value of f(x). So the graph og (x) is the graph of f(x) vertically stretched by a factor of 4.

The graph shown below confirms the conclusion.

Answer: C.
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 4.
