Determine the Equation of the Graph $13 \mathrm { ft }$

question 40

Multiple Choice

Determine the equation of the graph.
-A rotating beacon is located $13 \mathrm { ft }$ from a wall. The distance from the beacon to the point on the wall where the beacon is aimed is given by
$$a = 13 | \sec 2 \pi t | \text {, }$$
where $t$ is time measured in seconds since the beacon started rotating. Find a for $t = 0.41$ seconds. Ro your answer to the nearest hundredth.

• A) \(15.40 \mathrm { ft }\)
• B) \(31.00 \mathrm { ft }\)
• C) \(46.60 \mathrm { ft }\)
• D) \(- 15.40 \mathrm { ft }\) nd

Definitions:

Nearly Normal Condition

Nearly normal condition refers to a situation where a dataset or distribution closely approximates a normal distribution, meeting certain criteria for statistical analyses.

Confidence Interval

A range of values, derived from a dataset, that is used to estimate the likelihood of containing the true mean or proportion of the whole population.

Degrees of Freedom

The number of independent values or quantities which can be assigned to a statistical distribution, typically influencing the shape of the distribution.

Confidence Interval

A range of values derived from sample statistics that is likely to contain the value of an unknown population parameter.
