Y=A*sin(x*2pi/T)

A=max(y)=2
T=4pi

y=A*sin(x*2pi/T)=2*sin(x*2pi/4pi) = 2*sin(x/2)
y=2*sin(x/2) - is answer

A bowl contains 6 green grapes, 10 red grapes, and 8 black grapes. Which of the following is the correct
irina1246 [14]

Using the it's concept, the correct calculation for the probability of choosing a red grape and then without putting the red grape back into the bowl, choosing a green grape is:

p = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, we have that there is a total of 6 + 10 + 8 = 24 grapes. For the first grape, 10 are red, hence the probability that the first grape is red is:

pR = \frac{10}{24} = \frac{5}[12}

For the second grape, considering that the first was red and was removed, there will be 23 grapes, out of which 6 will be green, hence the probability that the second grape is green is:

pG = \frac{6}{23}

Hence the correct expression is found as follows:

p = pR \times pG = \frac{5}{12} \times \frac{6}{23} = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

Find the domain and range of the function
SVEN [57.7K]

Answer:

domain: (-∞ , ∞)

range: (-∞, 2]

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.
