Draw a graph of the number of bacteria versus time for the following story: dave is doing an experiment with a type of bacteria that he assumes divides in half exactly every 30 min. he begins at 8: 00 a. m. with 10 bacteria in a petri dish and waits for 3 hr. at 11: 00 a. m., he decides this is too large of a sample and adds chemical a to the dish, which kills half of the bacteria almost immediately. the remaining bacteria continue to grow in the same way. at noon, he adds chemical b to observe its effects. after observing the bacteria for two more hours, he observes that chemical b seems to have cut the growth rate in half.

its 8

step-by-step explanation:

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
