What is the equation of the following graph in vertex form? PLEASE HELP ME!

Mathematics
1 answer:
viktelen [127]3 years ago
6 0

Answer: Choice B

y = (x+3)^2 - 1

==================================================

Recall that vertex form is y = a(x-h)^2 + k with the vertex being (h,k)

From the given graph, it shows that (h,k) = (-3,1) is the vertex. So we plug this pair of values into the general function above to get

y = a(x-h)^2 + k

y = 1(x-(-3))^2 + (-1)

y = (x+3)^2 - 1

which is the final answer

note: a = 1 is the case for all four answer choices, so we don't have to worry about the value of 'a'

What is the probability that a marble chosen at random is
Brums [2.3K]

Answer:

P=\frac{6}{11}

Step-by-step explanation:

The probability can be defined as the ratio between the possible events and the total number of outcomes.

In this case, according to the image attached, the total number of outcomes is 11, because they are 11 marbles in total.

Now, the specific event is all shaded marbles or labeled with a multiple of 3. With this specific characteristics 6 marbles, because there are 5 shaded marbles and 6 is a multiple of 3. So, the possible events are 6.

Therefore, the probability is

P=\frac{6}{11}

The right answer is the last choice.
