Answer:
B] f(n) = 6(3)n − 1; f(5) = 486
Step-by-step explanation:
First, you have to identify which type of relation the points have. From the graph you can tell that it's an exponential growth. The x values change in the same amount every time, in this case by 1.
So if the relation is exponential, if we divide the y coordinates you should get the same result every time.
18 / 6 = 3
54 / 18 = 3
162 / 54 = 3
So the y value increases 3 times. That means that the next value should be 162*3 = 486.
Solve the equation of the function for n.
a(n) = 3n - 20
a = 3n - 20
a + 20 = 3n
(a + 20)/3 = n
n = (a + 20)/3
n(a) = (a + 20)/3
Answer:
3/5
Step-by-step explanation:
First add all of the balls together to know the total.
2 + 2 + 1 = 5
Probability of Green: 2/5
Probability of Red: 2/5
Probability of Blue: 1/5
Add red and blue together
2/5 + 1/5 = 3/5
3/5
Brainliest would be appreciated. :)
