Figure 2.20: The function $$\sin y +y^3=6-x^2$$ and its tangent line at the point $$(\sqrt{6},0)$$. Answer to: Assume that the profit generated by a product is given by P(x) = 5*sqrt(x), where x is the number of units sold. (b) Find the marginal revenue function. Get 1:1 help now from expert Algebra tutors Solve it with our algebra problem solver and calculator When evaluating square roots we ALWAYS take the positive answer. For instance, we can rewrite $\sqrt{15}$ as $\sqrt{3}\cdot \sqrt{5}$. By multiplying the variable parts of the two radicals together, I'll get x 4, which is the square of x 2, so I'll be able to take x 2 out front, too. 2(4 16x)-2(4 2y)+3(4 81x)-4(4 32y) What is the following sum? The 4 in the first radical is a square, so I'll be able to take its square root, 2, out front; I'll be stuck with the 5 inside the radical. The first rule we will look at is the product rule for simplifying square roots, which allows us to separate the square root of a product of two numbers into the product of two separate rational expressions. For the steps below assume $$y$$ is a function of $$x$$. A manufacturer has found that when m employees are working, the number of units of product produced per day is q = 10 &Sqrt… Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Learn vocabulary, terms, and more with flashcards, games, and other study tools. This suggests a general method for implicit differentiation. Start studying Algebra II Q3 Unit 1: Radical Operations and Equations. (a) Find the rate of change of p with respect to q. The graph of $x^2+(y-\sqrt{x^2})^2=1$ is very interesting and is show below using desmos. $- \sqrt {16} = - 4$ This may not seem to be all that important, but in later topics this can be very important. The first rule we will look at is the product rule for simplifying square roots, which allows us to separate the square root of a product of two numbers into the product of two separate rational expressions. If we want the negative answer we will do the following. This calculator simplifies ANY radical expressions. Example 1: to simplify $(\sqrt{2}-1)(\sqrt{2}+1)$ type (r2 - 1)(r2 + 1). Start studying Algebra 2 part 2 exam. Assume x ge 0 and y ge 0. For instance, we can rewrite $\sqrt{15}$ as $\sqrt{3}\cdot \sqrt{5}$. Assume x ge 0 and y ge 0. x2y3 + 2 x3y4+xy y Which of the following is a like radical to 3 7x? Suppose p = 100 − √ q 2 + 20 is a demand equation for a manufacturer’s product. 8.
