The probability of pulling out a nickle would be 1/6
Drawing a quarter after would have a 2/5 chance
Multiply the two and the probability of that happening is 2/30
Simplify to 1/15
Answer:
B)
Step-by-step explanation:
Given function:
We need to find the equivalent function.
By looking at the choices, we know that we have to convert the given function into its vertex form.
We apply completing square method to do so.
We have
First of all we make sure that the leading co-efficient is =1.
Since its already 1, so we move ahead to next term.
Isolating and terms on one side.
Subtracting both sides by 10.
In order to make the right side a perfect square trinomial, we will take half of the co-efficient of term, square it and add it both sides side.
square of half of the co-efficient of term =
Adding 9 to both sides.
Since is a perfect square of , so, we can write as:
Adding 1 to both sides:
[Vertex form]
∴ Equivalent function
Step-by-step explanation:
x = -4,
f(4) = -3(-4) + 15
= 12 + 15
= 27
f(0) = -3(0) + 15
= 0 + 15
= 15
f(5) = -3(5) + 1 5
=- 15 + 15
= 0
Answer: The correct answer is the last choice.
In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.
In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words it didn't move.
In the last segment, it moved up again for 2 hours.
