Add (16n2 + n + 1) + (4n2 - 5n - 2).​

Answers

Answer 1

Answer:

20n2-4n-1

Step-by-step explanation:

You combine like terms, so you add 16n2 with 4n2 to get 20n2. Then you add n with -5n to get -4n. Finally, you add 1 with -2 to get -1.

The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square is equal to the octagon. Find the length of the square and the length of a side of the octagon.

Please show work, I will give brainliest.

Answers

9514 1404 393

Answer:

square: 12 ft sidesoctagon: 6 ft sides

Step-by-step explanation:

This problem can be worked in your head.

If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.

__

We can let s represent the side length of the octagon. Then we have ...

  8s = perimeter of octagon

  4(s +6) = perimeter of square

These are equal, so ...

  4(s +6) = 8s

  s +6 = 2s . . . . . . divide by 4

  6 = s . . . . . . . . . . subtract s

The octagon has 6-ft sides; the square has 12-ft sides.

Step-by-step explanation:

From the diagram; |AB| = |AC|

The length AB is calculated as;

[tex]Sin\ 52^o = \frac{|BD|}{|AB|} \\\\|AB| = \frac{|BD|}{Sin\ 52^o} \\\\|AB| = \frac{12}{Sin\ 52^o} \\\\|AB| =15.228 \ m[/tex]

The length CD is calculated as;

[tex]Sin \ 31^o = \frac{|CD|}{|AC|} \\\\|CD| = |AC| \ \times \ Sin \ 31^o \\\\|CD| = 15.228 \ \times \ 0.515\\\\|CD| = 7.84[/tex]

|CD| = 2x - 6

2x - 6  = 7.84

2x = 7.84 + 6

2x = 13.84

x = 13.84 / 2

x = 6.92

x ≅ 7

Thus, 3 < x < 7

What is f(−1) for the function given? f(x)=x2−3x+8

Answers

Answer:

12

Step-by-step explanation:

I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.

Restaurant A sells 10 tacos for $8.50. How much does Restaurant A charge for 1 taco?

Answers

Answer:

Step-by-step explanation:

Given that,

Price of 10 tacos for $8.50

We need to find the charge for 1 taco.

We can find it using the unitary method.

10 tacos = $8.50

1 taco = [tex]\dfrac{8.5}{10}[/tex] = $0.85

Hence, restaurant A charge $0.85 for 1 taco.

Find the equation of the line.

Answers

Answer:

[tex]y=-\frac{3}{2} x+3[/tex]

Step-by-step explanation:

The slope (m) is [tex]-\frac{3}{2}[/tex] by finding the rise (the change in y ⇒ ∆y), over the run (the change in x ⇒ ∆x) from any two points from the line. In this case, the rise is -3, and the run is 2 OR you can say that the rise is 3, and the run is -2.

The y-intercept (b) is 3 because it’s where it intersects the y-axis. If you see the image, you can see that the line intersects the y-axis at the point (0, 3). So, the y-intercept (b) is 3.

Put it all together in Slope-intercept form, which is y=mx+b. So the m (slope) is [tex]-\frac{3}{2}[/tex] and the b (y-intercept) is 3. Plug those in to get: [tex]y=-\frac{3}{2} x+3[/tex]

BC= 3

Step-by-step explanation:

Suppose a line BD is 10 and it has a point C somewhere on the  line. It is given that BC is  3times and CD is 7 times  or algebraically  if we take x as a variable then according to the given information

BC+ CD= BD

3x+ 7x= 10

10x= 10

x= 10/10

x= 1

3x would give 3 (1)= 3

Hence the Line BC = 3

Read the article "Make a Change: Alternatives to Plastic Straws": Plastic is ruining the environment. Every year, 300 million tons of plastic are discarded in America, more than 8 million tons of which end up in the ocean. Over half of plastic waste is single-use plastic items such as bags, bottles, and food containers. Americans use 35 billion plastic water bottles a year. Similarly, over 1 million plastic bags are used every minute worldwide. These wasteful products are choking landfills and polluting waters. They should be, and can be, replaced with more environmentally friendly alternatives. A good example of a plastic item that should be replaced is the plastic straw. 500 million straws are used and discarded each year in America. That is enough straws to wrap around the whole of the Earth two-and-a-half times! Straws are, for the most part, completely unnecessary. Only a small number of people with certain medical conditions need straws for drinking. The rest of the population does not need straws. They simply have become accustomed to using them. Alternatives are available, but which one is best? Natural Alternatives Materials such as paper, straw, and bamboo are natural and biodegradable. They can also be used to make environmentally friendly drinking straws. Straws made from natural materials will decompose much more easily. They can be thrown in with food waste and composted. They are also relatively easy to find in stores and are inexpensive to buy. However, there are some drawbacks. Paper straws can quickly turn to mush when submerged in liquid. Likewise, drinking straws made from straw are not as strong as plastic and can tear easily. This makes both of these alternatives non-reusable. While bamboo is a more robust material, it too can only be reused a limited number of times. Bamboo must be responsibly sourced, as well, making it a more expensive option. Straw grass is similarly costly to use. Human-Made Alternatives Biodegradable plastics are now available and are used in many products, including straws. These plastics can decompose naturally in as little as 12 weeks. Unlike more natural alternatives, these straws look and feel the same as plastic straws. They are also stronger than natural products and can be easily mass-produced. Similar to natural straw alternatives, though, they are more expensive than plastic. They also must be disposed of properly (with food waste) or they will not fully decompose. Metal straws are another human-made alternative to plastic. Metal is very durable, which means that straws made from this material are long-lasting. They are more expensive to buy, but because they are reusable, they are actually cheaper in the long run. Glass straws are another alternative and offer many of the same benefits as metal straws. Both are dishwasher-safe and highly reusable. Unlike metal, however, glass can break easily, which is something that needs to be taken into account. Nevertheless, glass straws often feature unique designs that can be seen as works of art, which is a plus for some consumers. There are many alternatives to plastic straws currently on the market. While each one has its benefits and drawbacks, any of them would be a better choice than harmful plastic. On the other hand, going straw-less would be even better! How does the author's choice of words or phrases influence what the reader thinks about the topic in the article? The author uses phrases like "same benefits," "some drawbacks," and "many alternatives" to show while there are still positives and negatives to the alternatives, they are still better than plastic. The author uses phrases like "unique designs," "easily mass-produced," and "stronger than natural products" to show that plastic straws have many benefits compared to other materials. The author uses words like "drawbacks," "unlike," and "harmful" to create a negative feeling about the alternatives to making plastic straws, showing plastic is still the better option. The author uses words like "metal," "glass," "plastic," and "bamboo" to show the reader there is hope towards finding the best materials to use when producing straws.
