it's true. because it has more type of sums and head pain will come

Answer:

When two equations have the same slope but different y-axis, they are parallel. Since the two equations never intersect, the system has no solutions.

you can decide your answer from that explanation!

Answer:

See below.

Step-by-step explanation:

The y-intercept is the point where the line passes the y-axis. In this instance, that is at the point (0, 3).

The roots are the x-intercepts are the points where the line crosses the x-axis. In this instance, the roots are x = -3 and x = -1.

The turning point is the vertex of the equation. In this instance, the vertex is on the point (-2, -1).

Answer:

For [tex]x \in\mathbb{C}[/tex]

[tex]x = -2i[/tex]

[tex]x = 2i[/tex]

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]f(x)=x^3-7x^2+4x-28[/tex]

For [tex]f(x) = 0[/tex]

[tex]x^3-7x^2+4x-28 = 0[/tex]

We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.

[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]

Now we have

[tex](x^2+4)(x-7) = 0[/tex]

Therefore,

[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]

So,

[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]

Once [tex]\sqrt{-1} = i[/tex]

[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]

Answer:

The factors of given polynomial    x =-1 , -2 and x =3

Step-by-step explanation:

Step(i):-

Given the polynomial  

                    f(x) =  x³ - 7x -6

 put x =-1

               f(-1) = (-1 )³- 7(-1) - 6 = -1+7-6=0

(x+1) is a one factor

By using synthetic division

                   x³    x²      x      constant

     x=-1  ↓   1      0      -7        -6

             ↓   0     -1      1          6

                  1       -1      -6       0    

The polynomial    x² - x - 6

Step(ii):-

The factors ( x+1)(x² - x - 6 ) = 0

     x = -1 and x² - x - 6 =0

    x =-1    and  x² - 3x + 2 x - 6 =0

   x =-1     and  x (x -3) + 2( x-3) =0

   x =-1     and  (x+2)(x-3) =0

Final answer:-

The factors of given polynomial    x =-1 , -2 and x =3

Given that,

ABC is a right angle triangle, C is the right angle.

To find,

cosB = ?

Solution,

The sum of angle of a triangle is equal to 180 degrees. So,

∠A + ∠B + ∠C = 180°

Put ∠C = 90°

∠A + ∠B + 90° = 180°

∠A + ∠B = 90°

Taking cos with each term.

cosA+cosB = cos (90)

cosA+cosB = 0

cosB=-sinA

Hence, cosB = sinA.

Answer:

  1/2, 3/10

  1/21, 8/27

Step-by-step explanation:

Fractions are multiplied by multiplying the numerators and expressing that product over the product of the denominators:

 [tex]\dfrac{a}{b}\times\dfrac{c}{d}=\dfrac{ac}{bd}[/tex]

In several cases here, the numerator product has factors in common with the denominator product. Those can be cancelled, reducing the product fraction to lowest terms.

  [tex]\dfrac{3}{4}\times\dfrac{2}{3}=\dfrac{3\cdot2}{4\cdot3}=\dfrac{3\cdot2}{3\cdot2\cdot2}=\boxed{\dfrac{1}{2}}\\\\\dfrac{4}{5}\times\dfrac{3}{8}=\dfrac{4\cdot3}{5\cdot8}=\dfrac{4\cdot3}{4\cdot2\cdot5}=\boxed{\dfrac{3}{10}}\\\\\dfrac{1}{6}\times\dfrac{2}{7}=\dfrac{1\cdot2}{6\cdot7}=\dfrac{2}{2\cdot3\cdot7}=\boxed{\dfrac{1}{21}}\\\\\dfrac{4}{9}\times\dfrac{2}{3}=\dfrac{4\cdot2}{9\cdot3}=\boxed{\dfrac{8}{27}}[/tex]

Answer:look below

Step-by-step explanation: The prime factorization of number is the break down into factors which are prime numbers (numbers without factors except 1 and itself). The factors 22 and 32 are composite numbers since they have more than 1 and itself as factors. They are not prime.

However, the factorization of 22 * 32 * 5 will equal a number. 22*32*5 = 3, 520. But it does not match the solutions given.

Answer:

2464

Step-by-step explanation:

prime factors : 32,11,7

32×11×7=2464

Answer:

Step-by-step explanation:

From the given information:

For the first 10 ratings, the average value is 75.

For maintaining the average of 84 ratings for the first 21st rating, we have:

Total rating for 21 units = 84 * 21 = 1764

For 10 units = 84 *10 = 840

Now, the initial 10 unit average = 75 * 10 =750

The first 10 unit + last 10 unit = 840 + 750 = 1590

The difference = 1764 - 1590 =174 unit

So, in the 14th rating, he has to go with 174 units.

Answer:

[tex]Probability =0.1744[/tex]

Step-by-step explanation:

Given

Total

[tex]American = 11[/tex]

[tex]Canadian = 18[/tex]

Selection

[tex]American = 0[/tex]

[tex]Canadian = 4[/tex]

Required

Determine the probability of selecting a 4 committee member that are Canadian.

First, we calculate total possible selection.

[tex]Total = American + Canadian[/tex]

[tex]Total = 11 + 18[/tex]

[tex]Total = 27[/tex]

Number of ways to select 4 from 27 is:

[tex]^{27}C_4 = \frac{27!}{(27-4)!4!}[/tex]

[tex]^{27}C_4 = \frac{27!}{23!4!}[/tex]

[tex]^{27}C_4 = \frac{27*26*25*24*23!}{23!4!}[/tex]

[tex]^{27}C_4 = \frac{27*26*25*24}{4!}[/tex]

[tex]^{27}C_4 = \frac{27*26*25*24}{4*3*2*1}[/tex]

[tex]^{27}C_4 = \frac{421200}{24}[/tex]

[tex]^{27}C_4 = 17550[/tex]

Next, we calculate ways of selecting 4 Canadians from 18 is:

[tex]^{18}C_4 = \frac{18!}{(18-4)!4!}[/tex]

[tex]^{18}C_4 = \frac{18!}{14!4!}[/tex]

[tex]^{18}C_4 = \frac{18*17*16*15*14!}{14!4!}[/tex]

[tex]^{18}C_4 = \frac{18*17*16*15}{4!}[/tex]

[tex]^{18}C_4 = \frac{18*17*16*15}{4*3*2*1}[/tex]

[tex]^{18}C_4 = \frac{73440}{24}[/tex]

[tex]^{18}C_4 = 3060[/tex]

The required probability is:

[tex]Probability =\frac{3060}{17550}[/tex]

[tex]Probability =0.1744[/tex]
