Put the functions in the form \(P=P_{0} e^{k t}\). $$P=10(1.7)^{t}$$

Short Answer

Expert verified
The function is \(P = 10 e^{t \ln(1.7)}\).

Step by step solution

01

Identify Form Components

The given function is in the form \(P = 10(1.7)^t\). We need to convert it into the form \(P = P_0 e^{kt}\). In this form, \(P_0\) represents the initial value and \(t\) is the variable for time.
02

Determine Initial Value \(P_0\)

In the given function, \(P = 10(1.7)^t\), the initial value \(P_0\) is 10. This is the coefficient in front of the exponential expression.
03

Express \((1.7)^t\) as \(e^{kt}\)

The goal is to express \((1.7)^t\) in terms of the base \(e\). We start by writing \(1.7 = e^{ ext{ln}(1.7)}\). Then, \((1.7)^t = (e^{ ext{ln}(1.7)})^t = e^{t ext{ln}(1.7)}\).
04

Identify the Value of \(k\)

From the expression \(e^{t ext{ln}(1.7)}\), we identify that \(k = ext{ln}(1.7)\). Thus, \((1.7)^t = e^{kt}\), with \(k = ext{ln}(1.7)\).
05

Rewrite Function in the Form \(P = P_0 e^{kt}\)

Now, substitute the identified values back into the form. Therefore, \(P = 10 e^{t ext{ln}(1.7)}\) is the equivalent expression in the desired format.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Initial Value
The initial value, often denoted as \(P_0\), is a fundamental concept in understanding exponential functions. It represents the starting quantity before any growth or decay occurs. In many real-world situations, this could be the initial amount of something, like population, investment, or radioactivity.

In the context of the problem, the function is given as \(P = 10(1.7)^t\). Here, \(P_0\) is directly identified as 10, which is the coefficient in front of the exponential expression. This number signifies the initial size or value of whatever process or quantity is being modeled.

Knowing the initial value helps to set the stage for understanding how the quantity will change as time progresses, informing predictions and interpretations based on the exponential model.
Exponential Function
An exponential function is a mathematical function of the form \(P = P_0 e^{kt}\), where \(e\) is the base of the natural logarithm, approximately equal to 2.71828. Exponential functions are characterized by their constant proportional rate of growth or decay.

These functions are fundamental in modeling many real-world processes, such as population growth, radioactive decay, and financial investments, where quantities change rapidly and continuously over time.

In the original problem, the function \(P = 10(1.7)^t\) needs to be rewritten in terms of the natural base \(e\). This involves expressing \((1.7)^t\) as an equivalent expression using \(e^{kt}\). Understanding how to transform the exponential base is crucial to harnessing the full predictive power of an exponential model.
Mathematical Transformation
Mathematical transformation involves changing the form of a mathematical expression to fit a desired model or format. This is often needed when working with exponential functions to align them with standard forms like \(P = P_0 e^{kt}\).

In our exercise, the aim is to transform \((1.7)^t\) into an expression with the base \(e\). We do this by writing \(1.7\) in terms of \(e\), namely \(1.7 = e^{\ln(1.7)}\). Then, raising both sides to the power \(t\), we get \((1.7)^t = (e^{\ln(1.7)})^t = e^{t \ln(1.7)}\).

This transformation is important as it brings the function into a standard form easily understood in exponential analysis, where \(k\) becomes explicitly evident. This method of rewriting the expression lays the groundwork for further mathematical exploration and application of exponential functions.
