A stair handrail is made of parallelograms congruent at -PQRS, PQ = 17.5, ST = 18, and m / QRS = 110 °. Find each measure. Explain.

What is the average rate of change for this function for the interval from x=2 to x=4 ?

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined
