Across
- 1. Divide x2 – 9x – 10 by x + 1
- 2. (A reading list for a course in world literature has 20 books on it. In how many ways can you choose four books to read?)
- 5. A biologist is researching a newly-discovered species of bacteria. At time t = 0 hours, he puts one hundred bacteria into what he has determined to be a favorable growth medium. Six hours later, he measures 450 bacteria. Assuming exponential growth, what is the growth constant "k" for the bacteria? (Round k to two decimal places.)
- 6. 2 +2x+4) Factor x3−8
- 7. Simplify sqrt[144]
- 8. Solve log2(x) = 4
Down
- 1. A citrus grower wants to ship a select grade of oranges that weigh from 8 to 9 ounces in gift cartons. Each carton will hold three dozen oranges, in 3 layers of 3 oranges by 4 oranges. The weight of an orange is related to its diameter by the formula w = d cubed over 4, where d is the diameter in inches and w is the weight in ounces. Cartons can be ordered in whole-inch dimensions. What size cartons should the grower order?
- 3. write the standard form of the polynomial of -7x+5x^4
- 4. Simplify log2(x) + log2(y)
