Set B is defined as B={x|x is an integer}. Name two elements of B.
jenyasd209 [6]
By definition we have an integer number given by:
 An integer is an element of the numeric set that contains the natural numbers {N} = {1,2,3,4, ...}, its opposite and zero.
 On the number line we find the negative numbers to the left of the zero and to its right the positive numbers.
 We have then, according to the definition, that the following are whole numbers:
 -527, 1
 Answer:
 
B = {x | x is an integer}
 
-527 ∈ B
 
1 ∈ B

What is the area of a section of pavement that is 10 ft wide and 70 yd​ long? Give your answer in square feet. I think I have th
Elenna [48]

Answer:

  2100 ft²

Step-by-step explanation:

1 yard is 3 ft, so 70 yards is (70 yd)×(3 ft/yd) = 210 feet.

The area of the pavement is the product of its length and width:

  area = (210 ft)(10 ft) = 2100 ft²

_____

If you keep the units with the numbers as I have done here, you find that the product of (10 ft) and (70 yd) does not have the units of ft². Rather, the units are ft·yd, which is <em>not what the problem is asking for</em>.

Analyze the asymptotes of the function.
koban [17]

Answer:

vertical asymptote at x=-1

horizontal asymptote at y=0

Step-by-step explanation:

y=\frac{1}{x+1}

To find vertical asymptote we set the denominator =0 and solve for x

x+1=0 (subtract 1 from both sides)

x=-1

So, vertical asymptote at x=-1

To find horizontal asymptote we look at  the degree of both numerator and denominator

there is no variable at the numerator , so degree of numerator =0

degree of denominator =1

When the degree of numerator is less than the degree of denominator

then horizontal asymptote at y=0
