The population of a bacterial colony increases at an increasing rate for 1 hour, after which it continues to increase but at a rate that gradually decreases toward zero. Sketch a possible graph for the population P(t) as a function of time t.

Was it wrong of Roosevelt to try to "pack" the Supreme Court with judges in favor of the New Deal? Why?

New product. A taste test with 200 randomly selected people found that only three of them said that they would buy a box of new Sweet Wheats cereal. How many boxes could the manufacturer expect to sell in a country of 280 million people?.

Use an array, rectangular area, number line, or base-ten blocks to model each of these properties for a particular instance. a. associative property of multiplication: $(3 \times 5) \times 2=3 \times(5 \times 2)$ b. associative property of addition: $1.7+3.3=2.0+3.0$ because $1.7+(0.3+3.0)=$ $(1.7+0.3)+3.0$ c. existence of multiplicative inverses: $\frac{2}{3} \times \frac{3}{2}=1$ and $\frac{3}{2} \times \frac{2}{3}=1$ d. commutativity of multiplication (show on a number line and with a rectangular area model): $3 \times 5=5 \times 3$

Symbiotic relationships with mycorrhizal fungi are found in almost all present-day plant lineages. Mosses are a major exception—most mosses lack mycorrhizal associations. Assuming that mycorrhizae were a key factor in the colonization of land by plants, propose an explanation for the absence of mycorrhizae in present-day moss lineages.

perform the operation and write the result in standard form. 1+i / i - 3 / 4-i
