Write assignment statements that perform the following operations with the variables a, b, and c. a) Adds 2 to a and stores the result in b * b=a+2 b) Multiplier b times 4 and stores the result in a * a=b*4 c) Divides a by 3.14 and stores the result in b * b=a/3.14 d) Subtract 8 from b and stores the result in a * a=b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w=5, x=4, y=8, and z=2. What value will be stored in result in each of the following statements? a) Set result = x + y * 12= x + y b) Set result = z + 2 * 4=z * 2 c) Set result = y / x * 2=y / x d) Set result =y – z * b=y – z 5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.
Review Problems for Exam #3 - Math 111B Exam #3 will cover Sections 5.2 – 5.6 (Inverse Functions, Exponential and Logarithmic Functions) • Be able to identify when a function has an inverse function and be able to find that inverse • Identify an exponential function, solve problems involving exponential applications • Identify a logarithmic function, solve problems involving logarithmic functions and applications • Use logarithmic properties to condense or expand logarithmic expressions as needed • Solve exponential and logarithmic equations • Create an exponential model based on data points and use that model to predict behavior 1. Describe verbally the inverse of the statement. Then express both the statement and its inverse symbolically as a function and its inverse. “Take the cube root of x and add 1.” 2. Determine if the following functions are one-to-one: a) [pic] b) [pic] c) d) e) 3.
Begin by writing the corresponding linear equations, and then use back-substitution to solve your variables. 10–1301–8001 159–1 x,y,z=( , , ) 10–1301–8001 159–1 = x-13z=15y-8z=9z=-1 = x-13(-1)=15y-8(-1)=9z=-1 = x=2y=1z=-1 x,y,z=(2 , 1 , -1) Determinants and Cramer’s Rule: 2. Find the determinant of the given matrix. 8–2–12 8–2–12 = 8*2 - (-1)(-2) = 16 - 2 = 14 3. Solve the given linear system using Cramer’s rule.

Exponents, Scientific Notation, and Radicals Order of operations: Solve using the order of operations. Be sure to show each step to receive full credit. (–16 ÷ 2) × 4 – 3 + 82 (-8) x 4 (-32) -3+82 -29+ 82 - 372 Exponents: Define the product rule and the quotient rule in your own words. The product rule is a formal rule for differentiating problems where one function is multiplied by another. The quotient rule is a method of finding the derivative of a function that is the quotient of two other functions for which derivatives exist Using the product and quotient rule, solve the following: Product rule exercise: x^11* x^5= x^(11+5)=x^16 x^(–6 )* x^12 〖=x〗^(-6+12)=x^18 Quotient rule exercise: x^(30 )/x^10 = x^(30-10)=x^20 x^(30 )/x^(–10) =x^(30--10)=20 Scientific Notation: Refer to your textbook or any Internet source to answer the following question.

The solution of the system is the intersection point of the graphs of the given equations. II. Solution of the System A system of equations can be solved through Eliminations method, Substitution method or by a Graphical method. A. By elimination method Example 1: Solve the system of equation by elimination method x2 + y2 = 4 - eq’n (1) x2 - y2 = 4 - eq’n (2) Assigning equation (1) & (2) and eliminate y variable by adding the two equations, we have 2x2 = 8, and solving for x x2 = 4 → x = ±2 Using the value of x and solving for y using eq’n (1) (±2)2 + y2 = 4 4 + y2 = 4 y2 = 4 - 4 y2 = 0 → y =
