Answer:

Plane PQY

Step-by-step explanation:

A plane is defined by 3 non-linear points. This is because if 3 linear points are given, only a line has been defined; its plane could be at any angle. The only answer choice that has non-linear points is PQY.

The statement that best describes the functions represented in the graphs is B. Only function p is continuous and linear.

A linear function consists of functions where the variables has exponents of 1.

The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

A function at a place can only be continuous if it is defined there, has a limit there, and its value at that point is equal to the value of the limit there.

In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even." Although opportunity costs have been paid and capital has obtained the risk-adjusted, projected return, there is no net loss or gain, and one has "broken even."

In the given question, last year sales=  birr 100000

net profit= 8% of sales

Fixed costs= birr 170000

Estimated sales increase= 25%

Estimated net profit= birr 30000

Increase in fixed cost due to moving to low-rent warehouse= birr 30000

(a) The break-even point under the old situation (X):

   = 100,000 * a - 170,000

   =1,000,000 * 8%

   a= 25% (net profit)

   X*a= 1170,000

   X=680,000

   That is, the break-even point under the old situation is 680000.

(b) The break-even point under the proposed situation is:

      = 1,250,000 x b - 170,000- 30,000

      = 80,000 + 30,000

      b= 24.8%

      X*b=200,00

      X=806451

      The break-even point under the proposed situation is 806451 and

(c) The birr sales volume must be obtained under the proposed plan to make as much profit as last year is:

        X*b -200,000= 80,000

        X*b = 280,00

Hence, the probability of selecting two Democrats is [tex]45[/tex].

What is the probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.

The meaning of probability is basically the extent to which something is likely to happen.

Here given that,

Consider a political discussion group consisting of [tex]9[/tex] ​Democrats, [tex]9[/tex] ​Republicans, and [tex]5[/tex] Independents. Suppose that two group members are randomly​ selected, in​ succession, to attend a political convention.

Let us assume ,

The discussion of the democratic is [tex]x_1=9[/tex].

The discussion of the democratic is [tex]x_2=9[/tex].

The discussion of the democratic is [tex]x_3=5[/tex]

So, the total number of candidates are

[tex]x_t=x_1+x_+x_3\\\\=9+9+5\\\\=23[/tex]

Probability of independate candidate from the group of candidates is

[tex]P_1=\frac{x_3}{x_t}\\\\P_1=\frac{5}{23}\\\\[/tex]

As, the remaining number of candidates after the selectio of the independent candidate is

[tex]x_r=x_t-1\\\\x_r=23-1\\\\x_r=22[/tex]

Now, the remaining number of candidates from the group of total remaining candidates is

[tex]P_2=\frac{x_1}{x_r}\\\\P_2=\frac{9}{22}[/tex]

So, the probability of an independent Democrat using the probability is

[tex]P=P_1[/tex] × [tex]P_2[/tex]

[tex]P=\frac{5}{23}[/tex] ×[tex]\frac{9}{22}[/tex]

[tex]P=\frac{110(207)}{506}\\\\P=\frac{22770}{506}\\\\P=45[/tex]

The other roots of the cubic equation p(x) = 24·x³ - 46·x³ + 29·x - 6 are;

x = 1/2

x = 3/4

A cubic equation is an equation  that has 3 as the highest index.

The specified polynomial in the question is presented as follows;

P(x) = 24·x³ - 46·x² + 29·x - 6

The solution of the equation is; x =  (2/3)

Therefore, (x - 2/3) is a factor of the equation and we get;

(24·x³ - 46·x² + 29·x - 6) ÷ (x - 2/3)  has a remainder of 0

Dividing the above expression using long division, we get;

                    24·x²  - 30·x + 9

The other real roots of the specified equation can be found as follows;

The equation for the roots is; P(x) = 24·x³ - 46·x² + 29·x - 6 = 0

From the above long division, therefore;

24·x³ - 46·x² + 29·x - 6 = (24·x²  - 30·x + 9) × (x - 2/3) = 0

Which indicates; (24·x² - 30·x + 9) = 0 or (x - 2/3) = 0

The other solution are;

24·x³ - 30·x + 9 = 0

3·(·8·x² - 10·x + 3) = 0

8·x² - 10·x + 3 = 0

Solutions for the above equation in the form; a·x² + b·x + c = 0 can be obtained using the quadratic formula as follows;

The quadratic formula; x = [tex]\dfrac{-b\pm\sqrt{b^2 - 4\cdot a\cdot c} }{2\cdot a}[/tex]

By comparing the equation, 8·x² - 10·x + 3 = 0 to the equation, a·x² + b·x + c = 0, we get;

a = 8, b = -10, and c = 3

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8)

((-10)² - 4 × 8 ×3) = 2

Therefore;

x = (10 ± √((-10)² - 4 × 8 × 3))/(2 × 8) = (10 ± 2)/(16)

x = 3/4, and x = 1/2

Therefore, the other other roots in increasing sequence are;

If the rotation is clockwise the angle is 120°.

If the rotation is counterclockwise the angle is 240°

The correct options are A and D.

We assume that the rotation is clockwise.

First, we can see that the rotation from P to F is just a rotation of 90°.

(point P as at 9 on a clock and point F is at 12 on a clock).

To go from point F to G, we need to move one of the sections defined by the dashed lines, and we know that each one of these measures 30°, then we need to add another 30° to the angle.

90° + 30° = 120°

Then the angle of rotation to map P to G is 120°.

The correct option is D.
