On a coordinate plane, a parabola opens down. It has an x-intercept at (negative 5, 0), a vertex at (negative 1, 16), a y-intercept at (0, 15), and an x-intercept at (3, 0).
The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?
The domain is all real numbers. The range is {y|y < 16}.
The domain is all real numbers. The range is {y|y ≤ 16}.
The domain is {x|–5 < x < 3}. The range is {y|y < 16}.
The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}
Answers
The domain is all real numbers.
The range is {y|y ≤ 16}.
Option B is the correct answer.
We have,
The given parabola opens downwards and has a vertex at (-1,16).
So,
The parabola has a maximum value at y = 16.
Also, the y-intercept of the parabola is (0,15), which is below the vertex, and the parabola intersects the x-axis at (-5,0) and (3,0).
We can use the factored form of the equation of a parabola to find its equation in this case.
The factored form is:
y = a(x - h)² + k
where (h,k) is the vertex and "a" determines whether the parabola opens upwards or downwards.
Since the parabola opens downwards, "a" is negative.
Also, we know that the vertex is (-1,16), so we have:
y = a(x + 1)² + 16
To find "a", we can use one of the x-intercepts, say (-5,0).
Substituting these values into the equation gives:
0 = a(-5 + 1)² + 16
0 = 16a
a = 0
This indicates that the parabola is actually a line passing through (0,15) and (3,0). Therefore, the equation of the parabola is:
y = -x² - 2x + 15
The domain of this function is all real numbers because there are no restrictions on the values of x that can be plugged into the equation.
However, the range of the function is limited by the maximum value of y, which is 16.
Since the parabola opens downwards, all y values less than or equal to 16 are attainable.
Therefore, the domain is all real numbers, and the range is {y | y ≤ 16}.
Therefore,
The domain is all real numbers.
The range is {y|y ≤ 16}.

PLS
Answers
Here's how to solve the system of equations:
From the first equation, we can see that y = x - 3 + 12 = x + 9.
Substituting this expression for y into the third equation, we get:
x + 9 - 7 = z - 11
x + 2 = z
Substituting this expression for z into the second equation, we get:
x + 21 = x + 8 + 13
x + 21 = x + 21
This equation is true for all values of x, which means there are an infinite number of solutions. However, we can still find a specific solution by using any of the equations we've derived so far.
Using the expression for y in terms of x, we get:
y = x + 9
Using the expression for z in terms of x, we get:
z = x + 2
We can now substitute these expressions for y and z into any of the original equations to solve for x. Using the second equation, we get:
x + 13 = x + 8 + 13
x = 9
Now that we know x, we can substitute it into the expressions for y and z to get:
y = x + 9 = 18
z = x + 2 = 11
Therefore, the solution to the system of equations is (y, x, z) = (22, 9, 18).

Answers
Answer:
Step-by-step explanation:The system of equations represented by the given points is:1x + 0y = 1 (equation 1)
1x + 6y = 1 (equation 2)
8x + 26y = 1 (equation 3)
8x - 22y = 1 (equation 4)
We can use the first equation to solve for x in terms of y:1x + 0y = 1
1x = 1
x = 1
Then we can substitute x=1 into equations 2-4 to obtain three equations in terms of y:1(1) + 6y = 1 => 6y = 0 => y = 0
8(1) + 26y = 1 => 26y = -7/8 => y = -7/208
8(1) - 22y = 1 => -22y = -7/8 - 7 => y = 15/44
Therefore, the solution to the system is x = 1 and y = -7/208 or y = 0 or y = 15/44.
However, we are given that x = -2, which contradicts our solution of x = 1. Therefore, there is no solution to the system with the given values.

The critical value for a two-tailed test at the 0.05 significance level is 1.96.
The null hypothesis is that there is no difference in the proportion of men and women intending to vote for Donald Trump, and the alternative hypothesis is that there is a difference.
The test statistic is given by:
z = (p1 - p2) /√[(p×(1-p)×(1/n1 + 1/n2),
where p = (x1 + x2) / (n1 + n2) and x1 and x2 are the number of successes in samples 1 and 2 respectively, and n1 and n2 are the sample sizes of samples 1 and 2 respectively.
In this case, x1 = 120, x2 = 132, n1 = 250, and n2 = 240.
Plugging these values into the equation gives us z = 0.906.
Since the test statistic does not exceed the critical value, we fail to reject the null hypothesis. That is, there is not convincing evidence that there is a difference in the proportion of all men and the proportion of all women in this city who intended to vote for Trump at the 0.05 significance level.

The letters of "EAGLES" should be evenly spaced across a 63 inch wide banner, with no margins. Each letter is 8 inches wide. How many inches (x) should exist between each pair of letter?
Answers
Answer:
To evenly space the letters of "EAGLES" across a 63 inch wide banner with no margins, you would need to divide the remaining space between each letter of the word equally. With five letters total and each letter being 8 inches wide, the total width occupied by the letters is 40 inches. Therefore, the remaining space is 23 inches (63-40=23). To find out how many inches should exist between each pair of letter, you would divide the remaining space by the number of gaps between the letters, which is 4 (one less than the total number of letters in the word).
23 inches ÷ 4 gaps = 5.75 inches between each pair of letters.

From a group of 10 people, you randomly select 2 of them. What is the probability that they are the 2 oldest people in the group?
Answers
The probability that they are the 2 oldest people in the group is 0.011
Understanding probabilityProbability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain.
The probability of an event A is denoted by P(A)
From the question above, let us calculate the probability.
The probability that the first person selected is the oldest is 1/10.
Then, the probability that the second person selected is the second oldest is 1/9, since there are only 9 people left to choose from.
Therefore, the probability of selecting the two oldest people in the group is:
1/10 * 1/9 = 1/90
So, the probability of selecting the two oldest people in the group is 1/90 or approximately 0.011 or 1.1%.

Answers
Answer:
The last option
[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]
Step-by-step explanation:
Given equation is 6x - y = 14
To convert an equation in rectangular(cartesian) form, f(x, y) to polar f(r, θ) we use the following information
x = rcosθ
y = rsinθ
Substituting for x and y in the original rectangular equation 6x - y = 14,
6(rcosθ) - rsinθ = 14
Factoring out r on the left side,
r(6cosθ - sinθ) = 14

explicit formula for an, the nth term of the sequence 6, 0, -6, ....
Answers
Answer:

Step-by-step explanation:
As this sequence decreases, rather than increases, this tell us that the nth term of this sequence will be minus. The difference from 6 and 0 is 6, telling us that the decrease is by 6 each time. So now we know the nth term of this sequence; -6n, but the sequence of -6n is -6,-12,-18 and so on. We need 6,0,-6. To find out the second part of the nth term find the difference from the sequence given and the sequence of -6n. The difference is 12 because the 6--6 = 12. So now we get the nth term of the sequence -6n + 12 which is written as 12-6n.
Nth term = a1 + d(n-1)
= 6 + -6(n-1)
= 6 - 6n + 6

The binomial expansion is solved and the error in Dakota's statement is the incorrect substitution of 36g^2h^2 for the correct expression
Given data ,
Dakota made a mistake because the third term of the expansion of (2g + 3h) should have been 36g2h2. The binomial theorem asserts that the expansion of (2g + 3h) is as follows:
( x + y )ⁿ = ⁿCₐ ( x )ⁿ⁻ᵃ ( y )ᵃ
Here, x = 2g and y = 3h. Since term numbers begin at 0, since we are seeking for the third term, r = 2.
So , on simplifying the equation , we get
= nC2 * (2g)⁽ⁿ⁻²⁾ * (3h)²
= (n! / (2! * (n - 2)!)) * (2g)⁽ⁿ⁻²⁾ * (3h)²
= ((n * (n - 1)) / 2) * (2g)⁽ⁿ⁻²⁾ * (3h)²
Hence , the correct expression for the third term of the expansion of (2g + 3h) is ((n * (n - 1)) / 2) * (2g)^(n - 2) * (3h)², where n is the exponent in the binomial expansion.

So, making k subject of the formula, we have that
k = yx
Now, If y=-24 when x =36, we have that
k = - 24 × 36
= -864
So, substituting k into y, we have that
y = k/x
= -864/x
So, to find the value of x when y = 45, making x subject of the formula, we have that
x = -864/y
So, substituting y into the equation, we have that
x = -864/y
= -864/45
= -19.2
So, the value of x = -19.2
