Answer:
2(3-√13) is the answer
Step-by-step explanation:
Given that,
x = \frac{3 - \sqrt{13} }{2}
or, \frac{1}{x} = \frac{2}{3 - \sqrt{13} } (Taking reciprocal on both sides)
We know that,
(a + b)² = a² + b² + 2ab
or, (x \ + \frac{1} {x})^{2} = {x}^{2} + \frac{1}{x {}^{2} } + 2
or, {x}^{2} + \frac{1}{x {}^{2} } = (x \ + \frac{1}{x })^{2} - 2
Now,
or, {x}+ \frac{1}{x } = \frac{3 - \sqrt{13} }{2} + \frac{2}{3 - \sqrt{13} }
or, (3 - \sqrt{13 {})^{2} } + 4
2(3-√13) is the answer

Answer:
[tex]1.76[/tex] days
Step-by-step explanation:
**Note this propably is not what you are looking for but it gets you the final answer.**
Given the eqaution [tex]y=9^{5x}[/tex]
Lets solve for x.
Step 1.
Rewirte the equation as [tex]y=a^{bx}[/tex]. Where [tex]a=9[/tex] and [tex]b=5[/tex].
Step 2.
Take the natural logarithm of both sides. Then rewrite the left hand side using properties of exponents/logarithms.
[tex]ln(y)=b*x*ln(a)[/tex]
Step 3.
Divide both sides of the equation by [tex]b[/tex]
[tex]\frac{ln(y)}{b} =x*ln(a)[/tex]
Step 4.
Divide both sides of the equation by [tex]ln(a)[/tex]
[tex]\frac{ln(y)}{b*ln(a)} =x[/tex]
Now we have our equation to solve for the number of days.
Step 5.
Plug [tex]9[/tex] back in for [tex]a[/tex] and [tex]5[/tex] back in for [tex]b[/tex].
[tex]\frac{ln(y)}{5*ln(9)} =x[/tex]
Step 6.
We are given 243 million for [tex]y[/tex].
Lets plug in 243 million.
[tex]\frac{ln(243,000,000)}{5*ln(9)} =x[/tex]
Step 7.
Solve for x.
[tex]x=1.7575419...[/tex]
Lets round to the hundreth's place.
[tex]x=1.76[/tex]
1.76 days
2x squared + 13x - 24 =0
Answer: (2x - 3)(x + 8)
Step-by-step explanation:
2x² + 13x - 24 = 0, where is equal ax² + bx + c = 0 form. We get a = 2, b = 13, c = -24.
When a is not equal to 1, we multiply a and c. ac = 2(-24) = -48.
b in the equations means that the sum of two factor of ac is equal to 13. Then we need to find which two factor is add up to 13. In this case, we get -3 and 16.
2x² + 13x - 24 = 0
2x² + 16x - 3x - 24 = 0
2x(x + 8) - 3(x + 8) = 0
(2x - 3)(x + 8) = 0
Answer: x = -8, x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
This is a quadratic equation since it is in ax² + bx + c = 0 form! We will use the formula and use PEMDAS, the order of operations, while solving as well.
The quadradic formula, then plugging in to solve:
(please note before the square root is a ± sign. Brainly text editor will not allow me to add it)
[tex]x = \frac{-b\sqrt{b^{2} -4ac } }{2a}[/tex]
[tex]x = \frac{-13\sqrt{13^{2} -4(2)(-24) } }{2(2)}[/tex]
[tex]x = \frac{-13\sqrt{169 -4(2)(-24) } }{4}[/tex]
[tex]x = \frac{-13\sqrt{169 +192 } }{4}[/tex]
[tex]x = \frac{-13\sqrt{361 } }{4}[/tex]
Now it breaks into two parts:
[tex]x = \frac{-13-19}{4}[/tex] and [tex]x = \frac{-13+19}{4}[/tex]
[tex]x = \frac{-32 }{4}[/tex] [tex]x = \frac{6}{4}[/tex]
x = -8, x = [tex]\frac{3}{2}[/tex]

Please help pleeaassee!! >_<.
Answer:
Slope intercept form does not dictate whether or not a function is linear. What determines if a function is linear is if there is one independent variable, one dependent variable, and it makes a STRAIGHT line. This function is linear because there are only 2 variables and a horizontal line.
Levi could have determined that the graph was linear by checking the conditions stated above or graphing it out. Then, he would see that y = 2 is a straight horizontal line with an independent and dependent variable.

Space Shuttle Marion is observing the launch of a space
shuttle from the command center. When she first sees the
shuttle, the angle of elevation to it is 16°. Later, the angle
of elevation is 74°. If the command center is 1 mi from the
launch pad, how far did the shuttle travel while Marion was
watching? Round to the nearest tenth of a mile,
Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:
[tex]\tan{16^\circ} = \frac{1}{x_1}[/tex]
[tex]x_1 = \frac{1}{\tan{16^\circ}}[/tex]
[tex]x_1 = 3.5[/tex]
Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:
[tex]\tan{74^\circ} = \frac{1}{x_2}[/tex]
[tex]x_2 = \frac{1}{\tan{74^\circ}}[/tex]
[tex]x_2 = 0.3[/tex]
The distance is:
[tex]d = x_1 - x_2 = 3.5 - 0.3 = 3.2[/tex]
The shuttle traveled 3.2 miles while Marion was watching.

Use the triangle to evaluate each function. sin(a) = tan(a) = sec(a) =
The value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.
How do we find the sin, tan, and sec function?By right-angled triangle, we can find the trigonometric function from the sides of the triangle.
sin x = perpendicular/ hypotenuse
cos x = base/ hypotenuse
sec x = hypotenuse /base
From a triangle ABC of base 4, perpendicular 3, and hypotenuse 5, we get
sin a = perpendicular/ hypotenuse
= 3/5
cos a = base/ hypotenuse
= 4/5
sec a = hypotenuse /base
= 5/4
Hence, the value of the given function is as follows sin a = 3/5, cos a =4/5 and sec a = 5/4.

The pilot of a small plane is flying at an altitude of 2000 ft- The pilor plans to start the final descent toward a runway when the horizontal distance between the plane and the runway is ? mi. To the nearest degree what will be the angle of depression 19 from the plane to the runw'y at this point?
Using the slope concept, supposing the horizontal distance is of 1500 feet, the angle of depression will be of 37º.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
In this problem, we suppose an horizontal distance of 1500 feet, with a vertical distance of 2000 feet, hence:
[tex]\tan{\alpha} = \frac{1500}{2000}[/tex]
[tex]\alpha = \tan^{-1}{\left(\frac{1500}{2000}\right)}[/tex]
[tex]\alpha = 37^\circ[/tex]
The angle of depression will be of 37º.

4. If you are moving a 25 N weight, over a distance of 2.5 meters, how much work is being
done?
Answer:
62.5 J
Step-by-step explanation:
Formula
Work = Force x Distance (Displacement)Given :
Force = 25 NDistance = 2.5 mSolving
Work = 25 x 2.5Work = 62.5 JThe work done with the given force and distance is 62.5 Newton meter.
What is time and work?The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the Time taken when the amount of work done is constant.
Given that, force = 25 N weight and distance = 2.5 meters
We know that, work = Force×Distance
Here, work = 25×2.5
= 62.5 Newton meter
Therefore, the work done is 62.5 Newton meter.
