Introduction

Solving for a variable in an equation is a fundamental concept in mathematics, and it is essential to understand how to isolate the variable in a given equation. In this article, we will focus on solving for $R$ in the equation $R \cdot t^2 = 7$. This equation involves a quadratic term, and we will use algebraic manipulations to isolate $R$.

Understanding the Equation

The given equation is $R \cdot t^2 = 7$. This equation involves a product of two variables, $R$ and $t^2$, which equals a constant value, 7. To solve for $R$, we need to isolate $R$ on one side of the equation.

Isolating $R$

To isolate $R$, we can start by dividing both sides of the equation by $t^2$. This will cancel out the $t^2$ term on the left-hand side, leaving us with $R$ on the left-hand side.

R \cdot t^2 = 7
\Rightarrow \frac{R \cdot t^2}{t^2} = \frac{7}{t^2}
\Rightarrow R = \frac{7}{t^2}

Simplifying the Expression

The expression $\frac{7}{t^2}$ can be simplified further by taking the square root of the denominator. This will give us $R = \frac{\sqrt{7}}{t}$.

R = \frac{7}{t^2}
\Rightarrow R = \frac{\sqrt{7}}{t}

Conclusion

In this article, we have solved for $R$ in the equation $R \cdot t^2 = 7$. We started by dividing both sides of the equation by $t^2$ to isolate $R$, and then simplified the expression by taking the square root of the denominator. The final expression for $R$ is $R = \frac{\sqrt{7}}{t}$.

Example Use Case

Suppose we are given the value of $t$ as 2. We can substitute this value into the expression for $R$ to find the value of $R$.

R = \frac{\sqrt{7}}{t}
\Rightarrow R = \frac{\sqrt{7}}{2}
\Rightarrow R = \frac{2.6457513110645907}{2}
\Rightarrow R = 1.3228756555322954

Introduction

In our previous article, we solved for $R$ in the equation $R \cdot t^2 = 7$. In this article, we will answer some frequently asked questions related to solving for $R$ in this equation.

Q: What is the first step in solving for $R$ in the equation $R \cdot t^2 = 7$?

A: The first step in solving for $R$ in the equation $R \cdot t^2 = 7$ is to divide both sides of the equation by $t^2$. This will cancel out the $t^2$ term on the left-hand side, leaving us with $R$ on the left-hand side.

Q: Why do we need to take the square root of the denominator when simplifying the expression for $R$?

A: We need to take the square root of the denominator when simplifying the expression for $R$ because the denominator is a perfect square. Taking the square root of the denominator will give us a simplified expression for $R$.

Q: What is the final expression for $R$ in the equation $R \cdot t^2 = 7$?

A: The final expression for $R$ in the equation $R \cdot t^2 = 7$ is $R = \frac{\sqrt{7}}{t}$.

Q: Can we substitute any value of $t$ into the expression for $R$?

A: Yes, we can substitute any value of $t$ into the expression for $R$. However, we need to make sure that the value of $t$ is not equal to zero, because dividing by zero is undefined.

Q: What is the value of $R$ when $t = 2$?

A: When $t = 2$, the value of $R$ is $R = \frac{\sqrt{7}}{2} = \frac{2.6457513110645907}{2} = 1.3228756555322954$.

Q: Can we use the expression for $R$ to solve for $t$ in the equation $R \cdot t^2 = 7$?

A: Yes, we can use the expression for $R$ to solve for $t$ in the equation $R \cdot t^2 = 7$. We can rearrange the expression for $R$ to solve for $t$, which gives us $t = \frac{\sqrt{7}}{R}$.

Q: What is the value of $t$ when $R = 1$?

A: When $R = 1$, the value of $t$ is $t = \frac{\sqrt{7}}{1} = \sqrt{7} = 2.6457513110645907$.

Q: Can we use the expression for $R$ to solve for $t$ in the equation $R \cdot t^2 = 7$ when $R$ is a function of $t$?

A: Yes, we can use the expression for $R$ to solve for $t$ in the equation $R \cdot t^2 = 7$ when $R$ is a function of $t$. We can substitute the expression for $R$ into the equation and solve for $t$.

Q: What is the value of $t$ when $R$ is a function of $t$ and $R(t) = \frac{\sqrt{7}}{t}$?

A: When $R$ is a function of $t$ and $R(t) = \frac{\sqrt{7}}{t}$, the value of $t$ is $t = \frac{\sqrt{7}}{R(t)} = \frac{\sqrt{7}}{\frac{\sqrt{7}}{t}} = t$.
