A parabola can be drawn given a focus of (8,4) and a directrix of x = 6. Write the
equation of the parabola in any form.

Answers

9514 1404 393

Answer:

  x = 1/4(y -4)² +7

Step-by-step explanation:

A parabola can have the equation ...

  x = 1/(4p)(y -k)² +h

where the vertex is (h, k), and the vertex-to-focus distance is p.

The vertex is halfway between the focus and directrix, so has coordinates ...

  ((8, 4) +(6, 4))/2 = (7, 4)

The distance from the vertex to the focus is 8-7 = 1, so the equation can be written ...

  x = 1/4(y -4)² +7

According to a study, 15 out of 50 adults have allergies. What percentage of adults do not have allergies?

Answers

Answer:

70% of adults do not have allergies.

Step-by-step explanation:

It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.

35 x 2 =70

70/100 = .7

.7 is just the decimal form of 70%

Write the standard form equation of the parabola that passes through (20,−40),if the vertex at the origin and the axis of symmetry is vertical.

Answers

Answer:

y = -0.1x^2

Step-by-step explanation:

Start out with vertex form

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

The vertex at the origin

Therefor (h, k) = (0, 0)

y = ax^2

use point (20, -40) to find a

-40 = a(20^2)

-40 = a(400)

Divide both sides by

400

-0.1 = a

Therefor

y = -0.1x^2

This is standard form with a = -.01 and both b and c equal to zero

To Label or Not to Label: California Prepares to Vote on Genetically Engineered Foodsby Richard Dahl (excerpt)Although campaigns for and against GE labeling [for genetically engineered foods] in California are focusing heavily on economic impacts, the real debate revolves around a scientific question: Are these foods truly safe or not?I think its fair to say that most scientists think the techniques that are used [to create GE plants] are not inherently dangerous, says Peggy Lemaux, a cooperative extension specialist in the Plant and Microbial Biology Department at the University of California, Berkeley. In fact, in 2010 the European Commission released an analysis of 50 studies conducted on GE foods over the last 25 years and concluded that GE technologies posed no greater risks than conventional breeding technologies....The reason I dont worry about GMOs [genetically modified foods] is not because someone has convinced me with a big study that theyre safe, says Michael Eisen, an associate professor of genetics, genomics, and development at the University of California, Berkeley, and an investigator at the Howard Hughes Medical Institute. Its because when I look at the technology, I understand what this technology is doing. Theyre introducing proteins that have been very well characterized into plants, and I dont see any reason at all to suspect that these are harmful. . . .Some scientists, however, believe questions about the safety of GE foods are far from answered. Doug Gurian-Sherman, senior scientist with the Food and Environment Program at the Union of Concerned Scientists, says the question is not whether theres risk involved in GE foods, but whether its greater than risks posed by conventional foods. Because of the greater capacity to bring unknown quantities into the food supply, Im of the school that says it has somewhat higher potential for risk, he says. Other scientists say no. But I dont think its a settled debate.Hansen responds to claims that theres no evidence of harm from GE foods by saying, Thats just not true. I can show you all kinds of studies in the scientific literature that have . . . raised red flags that need to be followed up on. In one such study, investigators reviewed 19 studies of mammals fed GE soybeans and maize. They found that several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects, with the kidneys more affected in males and the liver more affected in females. The authors, noting the limitations of the 28- and 90-day assays they reviewed, pointed out that chronic toxicity testing is not required for GE foods, but that it should be.3Select the correct answer.Which description provides the best objective summary of the article in the passage?A.
