You perform a study to determine the depth at which a species of submerged aquatic plant grows the fastest. You conduct the study in a natural lake that has a large population of the plant growing at various depths. You measure the growth rate of a subset of the plant population (five plants) growing at each depth. You find that at a depth of 0 to 49 cm, the plants grow at rates of 1.6, 0.8, 0.4, 1.1, and 1.3 cm/day. At 50 to 99 cm, plants grow at rates of 1.2, 1.4, 1.5, 1.6, 1.9 cm/day. At 100 to 149 cm, plants grow at rates of 1.9, 2.3, 2.2, 2.5, 2.3 cm/day. Finally, at 150 to 199 cm, plants grow at rates of 1.5, 1.3, 1.6, 1.7, 1.1 cm/day. At which depth do plants have the greatest variance in the rate at which they grow?

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.

Raj encoded a secret phrase using matrix multiplication. using a = 1, b = 2, c = 3, and so on, he multiplied the clear text code for each letter by the matrix to get a matrix that represents the encoded text. the matrix representing the encoded text is . what is the secret phrase? determine the location of spaces after you decode the text. yummy is the corn the tomato is red the corn is yummy red is the tomato
