Photomath is a good app to help give u answers for math. Hope this helps u
The answers are B) and E)
We write the translation one by one:
D (3, 5)
D' (-6, 2)
That translates to: (x - 9, y - 3), because that is for passing from D to D': (3 - 9, 5 - 3) = (-6, 2).
Therefore if it is true for D and D' then, it has to be true for all others (you can check) for that rule to be true, so the correct answer is:
(x, y)→(x − 9, y − 3)
Answer:
Step-by-step explanation:
Function representing the bacterial growth has been given as,
a). Here 1200 represents the initial number of bacteria taken for the study (1).
b). 1.8 represents the growth factor by which the population of the bacteria is multiplying.
c). Second study is modeled by the function given as,
Here, initial population of bacteria = 1000
Difference in 1200 and 1000 in two studies means → Second study was conducted on 1000 bacteria while in study (1) number of bacteria were 1200.
(6 + 1/4)·4 = (6·4) + (1/4·4) = 24 + 1 = 25
Or, you can convert the mixed number to the improper fraction 25/4 and then multiply by 4 to get 25.
