Answer:
(-3,2)
Step-by-step explanation:
look at the dot called K, straight down you see -3 which is your X and if you look straight to the right of point K you see 2 which is your Y
(the whole bolded line that is horizontal is ur X and the whole bolded vertical line is ur Y)
Answer:
11 units
Step-by-step explanation:
perimeter of triangle ABC = AC+AB+BC
perimeter of triangle = 5 units + 4 units + 2 units
perimeter of triangle = 11 units
45/72 is divisible by 3.
45÷3/72÷3 = 15/24
15÷3/24÷3 = 5/8
so 5/8 is the simplest form.
This is exponential. Start with time increments of 1. If we have 4^x, then the bacteria population triples every hour (x=0 -> 1, x=1 -> 4, x=2 -> 16, etc). Now, the problem is that is quadruples every two hours. If you substitute one hour for two, the equation becomes 4^(x/2). (Now at 2 hours, it is 4, at 4 hours, it is 16, ect). I am assuming that the population starts at 1, but it doesn't have to. Let's say the starting population at time 0 is P. Then, the population at time x would be P*4^(x/2). You can verify this for any starting population P>=0 and for any time x>=0.
