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?
Answers
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

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.
Answers
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.

Step-by-step explanation:
The value of a house increased by 6%.
The house then had a value of £265000.
Work out the value of the house before the increase
Answers
+ 6% = x (1 + 6%) = x 1,06
with V = value before the increase
V x 1,06 = 265,000
so V = 265,000 : 1,06 = 250,000
The value of the house before the growth in its value was £250,000.
What do we mean by growth?We know that the value of most of the things in this world changes from time to time. When the value of an article is increased, we say that there's a growth in its value.
Growth is determined by the formula,
V = V₀(1+r), where V is the final price, V₀ is the initial price and r is the rate.
How do we solve the given question?We are told that the value of a house increased by 6%, reaching £265,000. We are asked to calculate its initial value.
Since the value has increased, we will use the formula for growth,
with V = £265,000, r = 6%, and V₀ is to be determined.
The formula is: V = V₀(1+r)
or, V₀ = V/(1+r) = 265000/(1 + 6%) = 265000/(1 + 6/100) = 265000/(106/100)
or V₀ = 265000*100/106 = 250000
∴ The initial value of the house is £250,000.

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)
Answers
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)

subtract the following mixed numbers 4 3/6 - 2 1/3
Answers
Answer:
13/6 or 2 1/6
Step-by-step explanation:
In order to solve this, we have to make the denominators equal
To do that, we will need to multiply 1/3 by 2/2 which will get us 2/6
Now that we have like denominators we can convert the mixed fractions to improper fractions:
4 3/6 ---> 27/6
2 2/6 ---> 14/6
Now we can comfortably subtract the two values and simplify if needed
27/6-14/6= 13/6
So:
4 3/6 - 2 1/3 = 13/6 or 2 1/6
