Look at the picture of a scaffold used to support construction workers. the height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled pr, is shown:

part a: what is the approximate length of rod pr? round your answer to the nearest hundredth. explain how you found your answer, stating the theorem you used. show all your work. (5 points)

part b: the length of rod pr is adjusted to 16 feet. if width pq remains the same, what is the approximate new height qr of the scaffold? round your answer to the nearest hundredth. show all your work. (5 points)

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
