The graph of a cosine function is shown. Which two points on the midline of the function are separated by a distance of one period?
Answers
Answer: (pi/8, 1) and (5*pi/8, 1)
Step-by-step explanation:
First, the midline is a horizontal line that cuts the graph in two halves.
In this case, we can see that the maximum of the function is y = 2.5, and the minimum is y = -0.5
The difference is:
Diff = (2.5 - (-0.5)) = 3
If we subtract half of the difference (3/2 = 1.5) to the maximum, we get the midline.
Then:
midline: y = 2.5 - (3/2) = 1
the midline is the line y = 1
Now, a period T is such that:
Sin(x) = Sin(x + T)
Two points that are in the midline and that are separated by a period will be two points on the line y = 1, and that are in corresponding parts of the graph.
Here the two points are, counting from left to right, the third and the 11th.
(both of them are in the line y = -1 and in the negative slope part).
The points are:
(pi/8, 1) and (5*pi/8, 1)

Step-by-step explanation:
First using the Pythagorean theorem, we know the hypotenuse [tex](c^2)[/tex] is 39 and one of the legs [tex](b^2)[/tex] is 36. So we would have:
[tex]a^2+36^2=39^2=a^2+1296=1521\\\text{Subtract 1296 on both sides:}\\a^2=225\\\text{find the square root of 225}\\\sqrt{225}=15[/tex]

Nick is making cookies the recipe requires 2 1/3 cup of flour and 1/6 teaspoons of salt. Nick wants to make the recipe using 1 cup of flour. To maintain the ratio, how much salt is required when 1 cup of flour is used?
Answers
Answer:
1 / 14 tsp salt
(1 over 14)
Step-by-step explanation:
Let's set the scale factor as x.
So,
2 1/3 * x = 1
Divide both sides by 2 1/3, which is equal to 7/3
x = 1 / (7/3)
x = 3 / 7
So, amount of salt would be written as:
(1/6) * (3/7) =
(1/2) * (1/7) =
1 / 14 tsp salt

A) y = 2x + 5C
B) y = 2x + 7
C) y = 2x + 9
D) y = 2x + 11
Answers
Answer:
y = 2x + 11
Step-by-step explanation:
y - 3 = 2(x + 4)
y - 3 = 2*x + 2*4
y -3 = 2x + 8
y = 2x + 8 +3
y = 2x + 11
A politician claims that a proposal for a new traffic law is broadly supported by both political parties and that a person from either political party is equally likely to support the proposed legislation. He cites two recent polls that said 70% of a random sample of 550 people from his political party supports the law, and 65% of a random sample of 420 people from the other political party supports the law. The 95 percent confidence interval for the difference in population proportions is (–0.010, 0.110). Based on the interval, is the politician’s claim justified?
Answers
Answer:
Based on the 95% confidence interval for the difference in population proportion, there is convincing statistical evidence that he is correct
Step-by-step explanation:
The proportion from the sample of people from his party that support the law = 70%
The number the members of the politicians political party that support the law = 550 people
The proportion from the sample of people from the other party that support the law = 65%
The number the members of the politicians political party that support the law = 420 people
The confidence level of the test = 95%
The given confidence interval for the difference in proportion, C.I. = (-0.010, 0.110)
Given that the 95% confidence interval for the difference in population proportion ranges from -0.010, to 0.110, it is 95% certain that 0 is among the likely difference in proportion between the two populations and therefore, there is sufficient statistical evidence to suggest that there is no difference in the proportion of the members of either political that support the proposed new traffic law.
