To solve the equation for k in the expression 4a + 9ab, we first need to clarify if the equation is presented in the format of an equation (like k = …) or just an expression that needs to be manipulated. However, since you mentioned solving for k, we will consider 4a + 9ab = … Read more

What is the sample space when tossing two coins, and how can we find the probability of getting exactly one head?

Tossing two coins involves looking at all the possible outcomes that can result from the toss. The sample space for this event consists of all combinations of heads (H) and tails (T) that can occur when the two coins are tossed. When you toss two coins, the possible outcomes are: HH (both coins show heads) … Read more

Is the expression 2√3 + 2√6 a rational number?

To determine whether the expression 2√3 + 2√6 is rational or not, we first need to understand what rational numbers are. A rational number can be expressed as the quotient of two integers, where the denominator is not zero. Let’s break down the expression: 2√3: This part represents 2 times the square root of 3. … Read more

What are all the solutions to the equation sec^2(x) = 2tan^2(x) within the interval [0, 2π]?

Finding Solutions to the Equation To solve the equation sec²(x) = 2tan²(x) within the interval [0, 2π], we start by rewriting the terms using the definitions of secant and tangent: sec(x) = 1/cos(x) tan(x) = sin(x)/cos(x) This allows us to express the equation in terms of sine and cosine: sec²(x) = 1/cos²(x) and tan²(x) = … Read more
