Give an example of each of the following, or argue that such a request is impossible.
a. A sequence that has a subsequence that is bounded but contains no subsequence that converges.
b. A sequence that does not contain 0 or 1 as a term but contains subsequences converging to each of these values.
c. A sequence that contains subsequences converging to every point in the infinite set {1, 1/2, 1/3, 1/4, 1/5,...}.
d. A sequence that contains subsequences converging to every point in the infinite set {1, 1/2, 1/3, 1/4, 1/5,...}, and no subsequences converging to points outside of this set.
Answer and Step-by-step explanation:
Solution:
(a) Let (bn) be a bounded sequence of (an) then, Bolzano- Weierstrass theorem,
(bn) contains a subsequence that is converges.
(b) The sequence :
Xn = 1 + (-1) n / 2 + 1/n
Clearly, (xn) does not contain 1 or 0.
If we take sequence (x2n), then it converges to 1 and when we take sequence (x2n+1),
Then it converges to 0.
(c) The sequence:
1
1,1/2
1, 1/2, 1/3
1, 1/2, 1/3, 1/4
i.e
(xn) = (1,1/2, 1, 1/2, 1/3, …)
Then, the subsequence (xn) that is identically ½ in second column and 1/3 is third column and so on.
It has sub sequence that converges to every point in infinite set {1, 1/2, 1/3, 1/4, 1/5…}.
(d) The sequence
{1, 1/2, 1/3, 1/4, 1/5…}
if we take sequence of given set, then, this set converges to zero. This is not contained in it.
If (xn) converges to every point in set {1, 1/2, 1/3 …} then there exists subsequence which converges to 0. And 0 does not belong to given set.

Ali graphs the function f(x) = –(x + 2)2 – 1 as shown. On a coordinate plane, a parabola opens up. It goes through (negative 3, 0), has a vertex at (negative 2, negative 1), and goes through (negative 1, 0). A vertical dashed line at (negative 2, 0) is parallel to the y-axis. Which best describes the error in the graph?
Answer:
The axis of symmetry should be x = 2
Step-by-step explanation:
should be written : f(x) = –(x + 2)^2 – 1
vertex form of the equation:
y = a(x - h)² + k
vertex means highest or lowest part
lowest part is (-2,-1)
axis of symmetry is
x = -b/2a

Help me please its urgent I need it done asap I need help if anyone could help me solve these problems that would be very helpful! (I'll give brainliest if you can solve all of them!) A company designs a circular dartboard such that the target area in the center is surrounded by a safety margin. Federal law requires that the area of the safety margin must be twice the area of the actual target in the center. If the total radius of the dartboard is 3 feet, what is the radius of the circular target in the center? (you must show the algebra for full credit)
Answer:
the radius of the circular target in the center is 2.12 feet
Step-by-step explanation:
the total area of the dartboard is
π x r² = π x 3² = 9π (28.27 ft²)
The area of the actual target in the center needs to be half of the dartboard (4.5 π) (14.14 ft²)
(Small area : 4.5π = π x r²
Divide both sides by π
4.5 = r²
√4.5 = r
r= 2.12132034....... (2.12 feet)

The slope of a line can be found by graph using rise over run ([tex]\frac{rise}{run}[/tex]). Look at the image below to see what this mean.
Rise = vertical
run = horizontal
I took two clear points on the line as seen below and drew a right angle that formed a right triangle with the line.
Now let's count how many units the rise is (look at the second image). This is 3 units
rise = 3
Count the units of the run (third image). This is 1 unit
run = 1
Let's put these two numbers together in the [tex]\frac{rise}{run}[/tex] form:
[tex]\frac{3}{1}[/tex] or simplified = 3
However, this is not the final answer. This is a negative slope, meaning that when you look at the line from left to right (like when you are reading words) the line reaches from the top left corner to the bottom right corner. A positive slope (reading left to right) reaches from the bottom left corner to top right corner.
To signify that the slope is negative you simply add a negative sign to it:
-3

what is 4 times x and pls explain it for me so then I can explain it
Answer:
4x
Step-by-step explanation:
In algebra, to avoid confusing the multiply sign and x, we always just put the terms next to each other to show that they multiply each other. Here, since x is unknown, we can't find a specific answer and therefore just write it as 4x, which means 4 times x.

Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. How fast did she drive to the soccer game?
Answer:
Hi Suuuman the answer for your deleted question is OP = 7.75
Step-by-step explanation:
– 2x + 23 and -8 + 2x = 23 - 2x and -8 + 2x = x= 31 /4 =7 3/4 =7.75 measure of OP = – 2 ( 7.75) + 23 = -15.5 + 23 = 7.75
Step-by-step explanation:
Answer for this question Sarah went on a 36 mile trip to a soccer game. On the way back, due to road construction she had to drive 18 miles per hour slower. This made the trip take 1 hour longer. 36 = 18 +18(a+1)How fast did she drive to the soccer game? let the returning speed be x mphgoing to game speed = x+18 Answer is 18 km/h while returning
Step-by-step explanation: Distance = 36
1 hour more while returning
time return - time going = 1
36/x - 36/(x+18) = 1
LCD= x ( x + 18 )
multiply by LCD
36 ( x + 18 ) - 36 x = 1 x ( x + 18 )
36*18=
36 x + 648 - 18 x = 1x ^2 + 18 x
648 = 1 x^2 - 18 x
x^2 + 18 x -648 = 0
x^2 +36x-18x-648=0
x(x+36)-18(x+36)=0
(x-18)(x+36)=0
x=-36 or 18
x =18
18 km/h while returning
while going speed = 18+18 = 36 km/h
