Solve and put answer in interval notation. $2x + 3 \ge 7$ or $6x - 3 < -15$
Prof. Branch Apple has hired your consulting company to forecast how new taxes proposed by the government will affect their production costs. Background. By way of background, you first introduce the Apple executives to the concepts of the cost curves and show how changes in the input costs affect these curves. Apple uses two inputs, capital and labor. In the short-run, Apple can not adjust the amount of capital it is using, but it can adjust the size of its workforce. Explain (and show in a graph) what happens to Apple's average total cost curve (ATC), average variable cost curve (AVC), and the marginal cost curve (MC) when (a) the cost of renting capital increases? (b) the cost of hiring labor increases?

QUESTION 1 (a) Arrange the following carbocations in order of increasing stability, i.e., least stable to most stable. View answer and explanation A B C D $^+$CH$_3$ Least stable Most stable
5.8 LAB: Palindrome A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: palindrome: bob Ex: If the input is: bobby the output is: not a palindrome: bobby Hint: Start by removing spaces. Then check if the string equals itself in reverse. LAB ACTIVITY 5.8.1: LAB: Palindrome 0 / 10 main.py Load default template... 1 user_input = input() 2 normal = "" 3 reverse = "" 4 for ch in user_input.lower(): 5 if ch != ' ': 6 normal += ch 7 reverse = ch + reverse
