Given:
Oil flow: n(t) = 7t where t is time and n = how far the oil is spreading
Area of the circular pattern the oil is forming:
A(n) = πn²
<span>Part A: Find the area of the circle of spilled oil as a function of time, or A[n(t)]
A[n(t)] = </span>π (7t)² = π * 49 * t²
<span>How large is the area of spilled oil after 8 minutes?
n(t) = 7t </span>→ 7 * 8 = 56
A(56) = 3.14 * 56² = 9,847.04 square units
or
A[n(t)] = π (7t)²
A[n(8)] = 3.14 * (7*8)² = 3.14 * 3,136 = 9,847.04 square units
Answer:
Repeating Decimals is a decimal fraction in which a figure or group of figures is repeated indefinitely, as in 0.666... Or as in 1.851851851…. It's basically is a decimal that is repeating the number.

Answer:</h2>
The graph which is a one-to-one function is:
Graph B
<h2>
Step-by-step explanation:</h2>
Function--
The graph of a function must always pass the vertical line test i.e. any line passing through the domain and parallel to the y-axis must pass through the graph exactly once.
and also for a function to be<em> one-one</em> the graph of the function must pass horizontal line test i.e. any line passing through the co-domain and parallel to the x-axis must intersect the graph at most once.
In the given graphs :
Graph A is not a function, since it does not pass the horizontal line test and hence we won't talk about being a one-one function.
Graph B is a function as well is one-one since it passes horizontal as well as vertical line test.
Graph C is a function but is not one-one as it fails the horizontal line test.
Hence, the correct answer is:
Graph B
Answer:
49
