Water is leaking out of a red cylindrical tank into a blue cylindrical tank that has been placed beneath the table on which the red tank stands. The height of the water in the red tank at time
t can be represented by a linear function. The height of the water in the blue tank at time t can
also be represented by a linear function. Under what condition would the rates of change of the
two functions be negatives of each other? Explain your reasoning.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores

Simply 8x squared + 5(7x squared- x) - 2x =

The reflexive property of congruence lets you say that ∠pqr ≅
