A). (–1, 0)
B). (0, –1)
C). (0, 1)
D). (1, 0)

Answers

Answer 1
Answer:

Answer:

  D).  (1, 0)

Step-by-step explanation:

The parabola opens to the right, so the focus will be to the right of the vertex at (0, 0). The only answer choice with a positive x-value is D.

___

The equation of a parabola with vertex (0, 0) can be written as

  y^2 = 4px

where p is the distance from the vertex to the focus. Here, that distance is 1.
Answer 2
Answer:

Answer:

D). (1, 0)  this is the only positive answer

Answer:

Perimeter A  = 122.5

Step-by-step explanation:

Set up the following proportion

The Perimeter of B = 12 + 9 + 9 + 5

The Perimeter of B = 35

7/2 = x/PerimeterB

7/2 = x / 35                   Cross multiply

7*35 = 2x                      Combine the left side

245  = 2x                      Divide by 2

245/2 = 2x/2                Do the division

122.5 = x

The Perimeter of A = 122.5

Problem 3

If you compare the sides opposite the angle marked with a single arc, you will get the scale factor.

If these triangles are similar, and one of the sides opposite their markings will give you the scale factor

18/7.2 = x/1 where x is the scale factor going from the larger to the smaller triangle.

2.5 = x

So if you multiply the smaller triangle's sides by 2.5 you get the larger triangle.

Many fundraisers ask for donations using e-mail and text messages. The paper "Now or Never! The Effect of Deadlines on Charitable Giving: Evidence From Two Natural Field Experiments" ( Journal of Behavioral and Experimental Economics [2016]: 1-10) describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by e-mail is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.32% of those who received and opened an e-mail request for a donation and 7.77% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (e-mail or text message) and suppose that the given percentages are based on sample sizes of 2000 (the actual sample sizes in the experiment were much larger). a. The study described is an experiment with two treatments. What are the two treatments? b. Use a 90% confidence interval to estimate the difference in the proportions who donate for the two different treatments c. Is there convincing evidence that the proportion who make a donation is not the same for the two different methods? Carry out a hypothesis test using a significance level of 0.05. d. Is there convincing evidence that the proportion who make a donation after receiving an email is smaller than the proportion who make a donation after receiving a text message? Carry out a hypothesis test using a significance level of 0.10.
