A circular pool has an area of approximately 154 square feet. To the nearest foot, how much fencing is needed to completely surround the pool?

Answers

Answer 1

Given parameters:

Area of pool = 154ft²

Unknown:

The circumference or perimeter of the pool = ?

Solution:

The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.

To solve this problem, we need to find the radius from the given area.

Area of a circle = π r²

154 = π r²

r² = [tex]\frac{154}{3.142}[/tex] = 49

r = 7ft

Now the circumference of a circle = 2 π r

= 2 x π x 7

= 44ft

The circumference of the circle is 44ft

Consider the two functions f(x) and g(x), where f(x) = 2x and g(x) is graphed below.

Graph of g(x)

Compare the rate of change of the two functions on the interval 2 ≤ x ≤ 3.

The rate of change of the function g(x) is greater than f(x).
The rate of change of the function f(x) is greater than g(x).
The rate of change of the function f(x) and g(x) are the same.

Answers

The slope of the graph is 2 .

So the rate of change of g(x) is 2, just like f(x).

In fact, g(x) is also = 2x, just like f(x) .

Answers

Answer:

Step-by-step explanation:

B) 9<x<5

X has to be more than 9. 9+8=17, which would be a straight line.

X has to be less than 25. 17+8=25, which would be a straight line.

Answer:

9 < x < 25

Step-by-step explanation:

The length of a side of a triangle must be greater than the difference between the lengths of the other sides and less than the sum of the lengths of other sides.

x must be greater than the difference between 17 and 8.

17 - 8 = 9

x > 9

x must be less than the sum of 17 and 8.

x < 17 + 8

x < 25

When you put the two inequalities above together, you get:

9 < x < 25

passes through (-7, -4) parallel to y=1/2x+9

Answers

Answer:

y = 1/2x -.5

Step-by-step explanation:

We know that is the line is parallel to the equation then the slopes are going to be the same we just have to find the a different y-intercept.

It's a simple as this just plug the points into the equation you have like this.

(-7,-4) (PLUG IN)

-4 = 1/2(-7) +b (I do plus be so we can get another y intercept)

-4 = -3.5 + b (add 3.5 on each side)

-.5 = b

the equation parallel to the first one is...

y = 1/2x -.5

The posted weight limit for a covered wooden bridge in Pennsylvania is 6000 pounds. A delivery truck that is carrying x identical boxes each weighing 14 pounds will pass over the bridge. If the combined weight of the empty delivery truck and its driver is 4500 pounds, what is the maximum possible value of x that will keep the combined weight of the truck, drives, and boxes below the bridge's posted weight limit?

Answers

Answer:

The answer to x is 107

Step-by-step explanation:

If the driver and truck weigh 4500 and the bridge is can hold 6000 lbs. than there is room for 1500 more lbs. multiply 14 by 100 and get 1400, than multiply 14 by 7 and get 98. Add those to to get 1498. So the answer is x=107

In the 21st century, with an intensely competitive consumer market, advertisers increasingly used digital technology to call greater attention to products. In 2009, for example, the world's first video advertisements to be embedded in a print publication appeared in Entertainment Weekly magazine. The thin battery-powered screen implanted in the page could store up to 40 minutes of video via chip technology and automatically began to play when the reader opened the page.For an advertisement to be effective, its production and placement must be based on a knowledge of the public and a skilled use of the media. Advertising agencies serve to orchestrate complex campaigns whose strategies of media use are based on research into consumer behavior and demographic analysis of the market area. A strategy will combine creativity in the production of the advertising messages with canny scheduling and placement, so that the messages are seen by, and will have an effect on, the people the advertiser most wants to address. Given a fixed budget, advertisers face a basic choice: they can have their message seen or heard by many people fewer times, or by fewer people many times. This and other strategic decisions are made in light of tests of the effectiveness of advertising campaigns.There is no dispute over the power of advertising to inform consumers of what products are available. In a free-market economy effective advertising is essential to a company's survival, for unless consumers know about a company's product they are unlikely to buy it. In criticism of advertising it has been argued that the consumer must pay for the cost of advertising in the form of higher prices for goods; against this point it is argued that advertising enables goods to be mass marketed, thereby bringing prices down. It has been argued that the cost of major advertising campaigns is such that few firms can afford them, thus helping these firms to dominate the market; on the other hand, whereas smaller firms may not be able to compete with larger ones at a national level, advertising at the local level or online enables them to hold their own.Finally, it has been argued that advertisers exercise an undue influence over the regular contents of the media they employ--the editorial stance of a newspaper or the subject of a television show. In response it has been pointed out that such influence is counteracted, at least in the case of financially strong media firms, by the advertiser's reliance on the media to convey a message; any compromise of the integrity of a media firm might result in a smaller audience for the advertising.For the assessment, you will write an objective summary of the article. Additionally, you will make an inference about the relationship between advertising and the price you pay for a product and/or service. What is the molar mass of Mg(ClO4)2? Please help thank you!
