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 ±

on the right side of the equation because |x|=±x.

R−3=±10

The complete solution is the result of both the positive and negative portions of the solution.

The probability that “a child ticket is bought for a play” and “the play is performed in the afternoon" is 36/363.

Probability is the likelihood that a stated event would occur. The probability that the event would happen lies between 0 and 1.

The probability that “a child ticket is bought for a play” and “the play is performed in the afternoon" = 36 / total number of tickets bought

36 / (36 + 12 + 127 + 188) = 36 / 363

The rectangular coordinates will be (x=7cot(θ), y=7).

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)

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

option B and option D

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.

Answer:

the slope of parallel lines are - the same

i.e,m1=m2

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.

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.

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.

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.

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.

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:

[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.

Same as 1/10000
