Grantham University Algebra: Continuously Compounded Interest Homework Question 1Evaluate the function at the indicated value of x. Round your result to three decimal places.Function: f(x) = 0.5^x Value: x = 1.7 -0.308 1.7 0.308 0.5 Question 2Solve for x. 3x = 81 7 3 4 -3 Question 3 Logarithms are the inverse of exponentials. True False Question 4The Logarithm Quotient Rule states: logb(x / y) = logb(x) + logb(y) logb(x / y) = logb(x) – logb(y) logb(x y) = y ∙ logb(x) logb(c) = 1 / logc(b) Question 5Use the properties of logarithms to expand the expression as a sum, difference, and/or constant multiple of logarithms. Assume all variables are positive.log3 9x log3 9 * log3 x log3 9 + log3 x log3 9 – log3 none of these Question 6 Select the graph of the function. Indicate which graph is correct: 1st, 2nd, 3rd, or 4th f(x) = 5x-1 Question 7 Evaluate the function at the indicated value of x. Round your result to three decimal places. Show your work Value: x=2 Question 8 The exponential equation y=bx is equivalent to the logarithmic equation x=logby True False Question 9Use the One-to-One property to solve the equation for x.e(3x+5) = e6 x = -1/3 x2 = 6 x = 1/3 x = 3 Question 10Write the logarithmic equation in exponential form.log8 64 = 2 82 = 16 82 = 88 82 = 64 864 = 2 Question 11Write the exponential equation in logarithmic form.43 = 64 log64 4 = 3 log4 64 = 3 log4 64 = -3 log4 3 = 64 Question 12The given x-value is a solution (or an approximate solution) of the equation.42x-7 = 16x = 5 True FalseQuestion 13Find the magnitude R of each earthquake of intensity I (let I0=1). (Hint: R=log (I/I0)I = 19000 3.28 5.28 4.28 2.38 Question 14 – show you work pH is a measure of the hydrogen ion concentration of a solution. It is defined as the negative logarithm of the hydrogen ion concentration. The equation is: pH = – log [H+] If an acid has an H+ concentration of 10-4, what’s the pH? Question 15 – show your work A general formula for exponential Growth can be given by: A = P ekt In your textbook, or using another reliable source, research what values, P, A, k and t represent and write your answer. (Hint: What do each of the variables stand for?) Question 16 – show your work Continuously compounded interest means your principal is earning interest and you keep earning interest on the interest earned. Research the formula for Continuously Compounded Interest and write it below. Question 17$2500 is invested in an account at interest rate r, compounded continuously. Find the time required for the amount to double. (Approximate the result to two decimal places.)r = 0.0570 13.16 years 10.16 years 11.16 years 12.16 years Question 18 – show your work Write Eulers Number (e) to three decimal places. Question 19 – show your work Exponential functions often involve the rate of increase or decrease of something such as a population, for example. If there is a population increase, it is a _______ function and when there is a decrease, it is a ________ function.
