Find the real roots of the equation
8/x^4 + 5/x^2 = 3
​

Answer:

[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex]

Step-by-step explanation:

When pulged into a calculator:

[tex]3^{3}[/tex]  ÷ [tex]3^{-4}[/tex] = 2187

When your options are pulged in you get this:

[tex]3^{-3}[/tex] ÷  [tex]3^{4}[/tex] = [tex]\frac{1}{2187}[/tex]

[tex]3^{3}[/tex] · [tex]3^{4}[/tex] = 2187

[tex]3^{7}[/tex] ÷ [tex]3^0[/tex] = 2187

3 · [tex]3^6[/tex] = 2187

because [tex]3^{-3}[/tex] ÷  [tex]3^{4}[/tex] doesn't equal 2187 that is your answer.

Step-by-step explanation:

14) sin45 = x/6 ---> x = 6sin45 = 4.24

cos45 = y/6 ---> y = 6cos45 = 4.24

15) Use sine law to solve for x, y and z.

[tex] \frac{x}{sin45} = \frac{25 \sqrt{2} }{sin60} \\ x = 25 \sqrt{2} \frac{sin45}{sin60} = 25 \sqrt{2} \frac{ \frac{ \sqrt{2} }{2} }{ \frac{ \sqrt{3} }{2} } \\ = \frac{50}{3} \sqrt{3} [/tex]

[tex]cos60 = \frac{y}{ \frac{50}{3} \sqrt{3} } \\ y = ( \frac{50}{3} \sqrt{3} )cos60 = ( \frac{50}{3} \sqrt{3} ) (\frac{ \sqrt{3} }{2} ) \\ y = 25 [/tex]

[tex]cos45 = \frac{z}{25 \sqrt{2} } \\ z = (25 \sqrt{2} )cos45 = (25 \sqrt{2} )( \frac{ \sqrt{2} }{2} ) \\ = 25[/tex]

Answer:

3. (-3,4)    x=-3, y=4

Step-by-step explanation:

1. 3x-y=-13

  -y=-13-3x

  y=13+3x

2. 4x+2y=-4

   4x+2(13+3x)=-4

   4x+26+6x=-4

    10x+26=-4

    10x=-4-26

    10x=-30

    x=-30/10

    x=-3

3.  y=13+3x

    y=13+3(-3)

    y=13-9

    y=4

Answer:

[tex]ML = 58[/tex]

Step-by-step explanation:

Given

[tex]JK=3x+11, ML=10x-12, NP=45[/tex]

See attachment

Required

Length ML

First, calculate x using the following equivalent ratios

[tex]JK : NP = NP : ML[/tex]

Express as fraction

[tex]\frac{JK }{ NP} = \frac{NP }{ ML}[/tex]

Cross Multiply

[tex]JK * ML = NP * NP[/tex]

Substitute values:

[tex](3x +11) * (10x - 12) = 45 * 45[/tex]

Expand

[tex]30x^2 - 36x + 110x - 132 = 2025[/tex]

[tex]30x^2 +74x - 132 = 2025[/tex]

Collect like terms

[tex]30x^2 +74x - 132 - 2025=0[/tex]

[tex]30x^2 +74x -2157=0[/tex]

Using a calculator:

[tex]x \approx -10[/tex] and [tex]x \approx 7[/tex]

Given that:

[tex]ML=10x-12[/tex]

Substitute values for x

[tex]ML=10*-10-12 = -100 - 12 = -112[/tex]

[tex]ML=10*7-12 = 70 - 12 = 58[/tex]

ML cannot be negative; So:

[tex]ML = 58[/tex]

Answer:

-3/4

Step-by-step explanation:

The answer will be option c which is short dash 3 over 4.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

Given points are:(1,9)   and  (3,6)

The slope of the line will be calculated as:-

y = mx + c

9 = m+c

6 = 3m+c

By solving the above linear equations we will get the value of m which will be our slope.

m = -3/2

Hence the answer will be option c which is short dash 3 over 4.

Answer:

Step-by-step explanation:

The above-listed answer choices are the only ones that are self-consistent.

The quotient choices all have a leading coefficient of 3, and the result of dividing by <some number> is a leading coefficient of 1. Obviously, the <some number> must be 3 (first choice on the second menu).

Looking only at the constant term, we see that after division by 3, we have 3. So the original quotient constant term must be 3×3 = 9 (first choice on the first menu). Note that we have chosen the correct answer simply by looking at coefficients, not even bothering with actual division of variables.

therefore ,

⤳(5x-13)° + (11x+65)° = 180°

⤳5x -13° + 11x + 65° = 180°

⤳16x + 52° = 180°

⤳16x = 180° - 52°

⤳16x = 128°

Answer:

4√3/3

Step-by-step explanation:

Find the diagram attached below

Considering angle 60°

Opposite side = 2

Hypotenuse = x

Using the SOH CAH TOA identity

sin theta  = opposite/hypotenuse

sin 60 = 2/x

x = 2/sin60

x = 2/(√3/2)

x = 2 * 2/√3

x = 4/√3

Rationalize

x = 4/√3 * √3/√3

x = 4√3/3

Hence the value of x in its simplest form is x = 4√3/3

Answer:

Perimeter = 25

Step-by-step explanation:

J(-2, 5)

K(1, 1)

L(1, -1)

M(-5, -4)

N(-5, 1)

Formula for distance between 2 coordinates is;

d = √((x_2 - x_1)² + (y_2 - y_1)²)

Thus;

JK = √((1 - (-2))² + (1 - 5)²)

JK = √25

JK = 5

KL = √((1 - 1)² + (-4 - 1)²)

KL = √25

KL = 5

LM = √((-5 - (-1))² + (-4 - (-1))²)

LM = 5

MN = √((-5 - (-5))² + (1 - (-4))²)

MN = 5

JN = √((-5 - (-2))² + (1 - 5))²)

JN = 5

Thus;

Perimeter = 5 + 5 + 5 + 5 + 5

Perimeter = 25

The probability of winning the grand prize is 0.00101 if the In the Michigan State Lottery, a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.

Total outcome = C(49, 6)  (repetition not allowed)

= 13983816

Favourable outcomes = 49⁶

Probability of winning the grand prize:

= 13983816/49⁶

After calculating:

P = 0.00101

Thus, the probability of winning the grand prize is 0.00101 if the In the Michigan State Lottery, a player wins the grand prize by correctly picking 6 different numbers from 1 to 49.
