Your Answer is... (-7, 13) Which is C.
Step-by-step explanation:
Factor then solve to find the complex solutions.
Remove the absolute value term. This creates a ±

Convert the polar equation to rectangular coordinates. (use variables x and y as needed. )
The rectangular coordinates will be (x=7cot(θ), y=7).
What are polar coordinates?A pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line.
We have the standard conversion toolbox:
[tex]x=rcos(\theta)\\\\y=rsin(\theta)[/tex]
Here it is given that
[tex]r=7cosec(\theta)[/tex]
so
[tex]x=7cosec(\theta)\times cos(\theta)=\dfrac{7cos(\theta)}{sin(\theta )}=7cot(\theta)\\\\\\y=7cosec(\theta)\times sin(\theta)=\dfrac{7sin(\theta)}{sin(\theta)} = 7[/tex]
therefore the rectangular coordinates are (7cot(θ), 7)

It seems that every carton of eggs at the supermarket contains at
least one broken egg. If, in fact, it has been determined that
3 percent of the eggs supplied to a supermarket are cracked,
what is the probability that if you buy two dozen eggs none of
your eggs will be cracked?
The probability that if you buy two dozen eggs, none of your eggs will be cracked is 94.09% if the 3 percent of the eggs supplied to a supermarket are cracked.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
3 percent of the eggs supplied to a supermarket are cracked.
The probability that no eggs are cracked = 1 - 0.03 = 0.97
The probability that if you buy two dozen eggs, none of your eggs will be cracked:
= 0.97×0.97
= 0.9409
= 94.09%
Thus, the probability that if you buy two dozen eggs, none of your eggs will be cracked is 94.09% if the 3 percent of the eggs supplied to a supermarket are cracked.

Answer:
-7
Step-by-step explanation:
| anything inside these vertical lines becomes positive when the lines are removed. These lines are absolute value lines |
So |-2| becomes 2 when absolute bars are removed.
Using this logic, |-3| becomes 3 when bars removed. Thus 3 - 10 = -7

Answer:
[tex]10^{-4} = 0.0001[/tex]
Step-by-step explanation:
Negative exponents make the base a reciprocal:
[tex]x^{-1} = \frac{1}{x}\\x^2 = \frac{1}{x^2}\\[/tex]
Therefore, we can rewrite [tex]10^{-4}[/tex] as:
[tex]10^{-4} = \frac{1}{10^4} = \frac{1}{10000} = 0.0001[/tex]
10^-4 = 0.0001
1 x 10^-4 = 10^-4
It's a negative power - so you divide the 1 by 10000 - to get 0.0001.

Step-by-step explanation:
Nerys checks her tax bill from last year
the tax rates were as follows:
•No tax on the first £11,000 of earnings
•Earnings in excess of £11,000 and up to £43,000 taxed at a rate of 20%
•Earnings in excess of £43,000 and up to £ 150,000 taxed at a rate of 40%
•Earnings over £150,000 taxed at a rate of 45%
Last year Nerys earned £162,700 before tax.
how much tax did she pay in total?
Answer:
£54,915
Step-by-step explanation:
The tax table is applied as follows:
first 11,000 -- no tax
11,000 to 43,000 -- tax is 0.20 × (43,000 -11,000) = 6,400
43,000 to 150,000 -- tax is 0.40 × (150,000 -43,000) = 42,800
150,000 to 162,700 -- tax is 0.45 × (162,700 -150,000) = 5,715
Then the total tax on earnings of £162,700 is ...
£6,400 +42,800 +5,715 = £54,915
Nerys paid a tax of £54,915.
_____
Additional comment
The tax computation could be simplified to ...
f(x) = max(0, 0.2x -2200, 0.4x -10800, 0.45x -18300)
In this instance, the value 0.45x -18300 is the highest, at £54,915. Not all the computations are required if you realize the lines cross at x = 11,000, 43,000, and 150,000.

the slope of parallel lines are - the same

the slope of perpendicular lines are- negative reciprocals
i.e,m1*m2= -1
where, m1 and m2 slopes of two lines
A. The slope of parallel lines are: the same/equal
B. The slope of perpendicular lines are negative reciprocals.
What are the Slopes of Parallel and Perpendicular Lines?If two lines are parallel to each other, they will have the same slope. If the slope of one is 4, the slope of the other line that is parallel to it would also be 4.
On the other hand, the slope of perpendicular lines are negative reciprocal of each other. That is, if the slope of one is, -1, the slope of the other line would be 1.
Therefore, parallel lines have the same slope, while perpendicular lines have slope values that are negative reciprocal to each other.

In trapezoid PQRS, if segment XY is the midsegment, which could be the lengths PQ and SR? Select all that apply.
17 cm and 31 cm
18 m and 30 m
4 cm and 8 cm
9 cm and 15 cm
12 cm and 36 cm
18 cm and 30 cm
please explain how you get the answer :)
Answer:
17 cm and 31 cm
12 cm and 36 cm
18 cm and 30 cm
Step-by-step explanation:
The midsegment of a trapezoid is equal to the average of the two bases. When taking an average of two numbers, you add them and divide by 2. So the equation will be as follows:
[tex]\frac{PQ + SR}{2} = XY[/tex]
XY is given to be 24, so:
[tex]\frac{PQ + SR}{2} = 24[/tex]
Multiplying on both sides gets us:
[tex]PQ + SR = 48[/tex]
So any values of PQ and SR that add to 48 work. Therefore, we will sum the given options:
17 cm + 31 cm = 48 cm
18 m + 30 m = 48m (Did you mean meters?)
4 cm + 8 cm = 12cm
9 cm + 15 cm = 24cm
12 cm + 36 cm = 48cm
18 cm + 30 cm = 48 cm

According to the rational root theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 – 2x4 9x3 – x2 12? f(x) = 3x5 – 2x4 – 9x3 x2 – 12 f(x) = 3x6 – 2x5 9x4 – x3 12x f(x) = 12x5 – 2x4 9x3 – x2 3 f(x) = 12x5 – 8x4 36x3 – 4x2 48
According to the rational root theorem, the function that has the same set of potential rational roots is f(x) = 3x^5 – 2x^4 – 9x^3 + x^2 – 12.
Calculations and Parameters:Given the function:
g(x) = 3x^5 – 2x^4 + 9x^3 – x^2 + 12
We would have to find the rational roots and this would be done by:
Identifying the factors of 12 and 3.
After this, there would have to be an analysis of the factors and we can see that the correct answer is f(x) = 3x^5 – 2x^4 – 9x^3 + x^2 – 12.
