I used the Desmos Polar graph and got the correct answer!!!
A point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]
What is polar coordinate system?"It is a two-dimensional coordinate system in which points are given by an angle and a distance from a central point. ""A point are given as [tex](r,\theta)[/tex], where r is the distance of the point from the pole, and [tex]\theta[/tex] is the measure of the angle."For given question,
We have been given four points.
[tex]A=(5,\frac{\pi}{6} ), B=(5,\frac{5\pi}{6} ),C=(5,\frac{7\pi}{6} ),D=(5,\frac{11\pi}{6} )[/tex]
If we plot the above points on the polar coordinate plane then it would be as shown below.
We need to find the point having coordinates [tex](5,-\frac{7\pi}{6} )[/tex]
If we reflect a point [tex]C(5,\frac{7\pi}{6} )[/tex] about polar-axis then the coordinates of the reflected point would be [tex](5,-\frac{7\pi}{6} )[/tex]
Therefore, point C reflected about polar-axis has coordinates [tex](5,-\frac{7\pi}{6} )[/tex]

Answer:
Step-by-step explanation:
Look at the determinant.
a = k
b = 1
c = k
sqrt(b^2 - 4*k*k)
sqrt(1 - 4k^2)
The only way this can work out to repeated solutions is if k = +/- 1/2
That way 1 - 4(1/2)^2 = 0 or 1 - 4*(-1/2)^2 = 0
That way both solutions will be
-b / 2a
-1 / 2/(1/2) = - 1
or
-1 / 2(-1/2) = 1
So the answer is k = 1/2, - 1/2

2. Neil's airplane needs a full tank of fuel
to travel 2,600 miles. How many tanks
of fuel, t, does Neil's airplane need to
travel no more than 7.800 miles?
Part A
Write an inequality to represent this
situation.
Part B
Solve the inequality. What does the
solution represent in this situation?
The airplane needs no more than 3 tanks of fuel to travel no more than 7,800 miles. The solution represents the maximum number of tanks of fuel that Neil's airplane can use to travel no more than 7,800 miles without running out of fuel.
What is inequality?
In mathematics, an inequality is a relation that makes a non-equal comparison between two numbers or other mathematical expressions.
Part A:
Let x be the number of tanks of fuel needed to travel no more than 7,800 miles. Since the airplane needs a full tank of fuel to travel 2,600 miles, we can write the inequality:
x(2,600) ≤ 7,800
This inequality states that the total distance traveled (2,600 miles per tank) multiplied by the number of tanks (x) must be less than or equal to the maximum distance of 7,800 miles.
Part B:
To solve the inequality, we can divide both sides by 2,600:
x ≤ 3
Hence, the airplane needs no more than 3 tanks of fuel to travel no more than 7,800 miles. The solution represents the maximum number of tanks of fuel that Neil's airplane can use to travel no more than 7,800 miles without running out of fuel.

Answer:
The ordered pair to represent the second term as an ordered pair is:

Background knowledge about the sequence function
A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).
1, 2, 3, 4, .... n, ....
↓
a₁, a₂, a₃, a₄, .... aₙ, ....
Here,
1 gets mapped onto a₁,
2 gets mapped onto a₂, and so on
The numbers a₁, a₂, a₃, a₄, .... aₙ, .... are the terms of the sequence.
The number aₙ is the nth term of a sequence.
And the sequence function is denoted by {aₙ}.
Given the sequence
3, 9, 15, 21, ...
Here,
a₁ = 3 is the first term
a₂ = 9 is the second term
Thus, the ordered pair to represent the second term as an ordered pair is:

Write an equation of the line that passes through the pair of points. (−4, −2), (4, 0)
Answer:
y = 1/4x-1
Step-by-step explanation:
Ok first, you need to find the slope:
0+2 = 2=1
4+4 = 8=4
Slope: 1/4
y=1/4x+b
Now you need to find the y intercept which is b. For that you can take a coordinate pair and substitute it in the equation to find b.
I will use (4,0)
0=1/4 X 4 + b
0=x+b
minus x on both sides. x=1
-1=b
An equation of the line that passes through the pair of points
(- 4, - 2), (4, 0) is y + 2 = (1/4)(x + 4).
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, A line that passes through the pair of points. (−4, −2), (4, 0).
We also know slope(m) = (y₂ - y₁)/(x₂ - x₁) = (0 + 2)/(4 + 4) = 1/4.
So, the equation of a line in point-slope form is y - y₁ = m(x - x₁).
∴ y + 2 = (1/4)(x + 4).

A library has been given a specific amount of money and can buy 350 hardback books costing
£15.75 each
a How many books costing £10.50 could be bought instead?
b What type of proportion does this represent
Answer:
525 books
Step-by-step explanation:
Total books = 350
Cost of each book = £15.75
Total cost = 350 × £15.75
= £5,512.5
a. How many books costing £10.50 could be bought instead?
Instead of using £5,512.5 to buy 350 books at £15.75 each,
Number of books = total cost / cost per book
= £5,512.5 / £10.50
= 525 books
£5,512.5 can be used to buy 525 books at £10.50 each
The proportion is a direct proportion
