Consider the function defined by f(x) lnx/x^4 for x > 0 and its graph y = f(x).
The graph of f has a horizontal tangent at point P. Find the coordinates of P.
Answer:
[tex]\sqrt[4]{e};\frac1{4e}[/tex]
Step-by-step explanation:
The first derivative of [tex]f(x)[/tex] will give, for each x, the slope of the tangent at that specific x. Let's calculate the derivative, applying the quotient rule.
[tex]D(\frac AB) = \frac{A'B-AB'}{B^2}\\f'(x)= \frac1{x^8}[(\frac1x)x^4-(lnx)(4x^3)]=\frac1{x^8}[x^3(1-4lnx)]=\frac{1-4lnx}{x^5}[/tex]
Now, to find the point with an horizontal tangent (called "stationary points"), we set the first derivative equal to 0. Considering that we're working with [tex]x > 0[/tex] we deal only with the numerator.
[tex]1-4lnx = 0 \rightarrow lnx= \frac14\\x=e^\frac14 =\sqrt[4]{e}[/tex]
At this point we Replace the value we found in the equation to find it's y coordinate
[tex]f(\sqrt[4]e) = \frac{ln\sqrt[4]e}{\sqrt[4]e^4}= \frac{\frac14}{e} = \frac1{4e}[/tex]

What is perimeter of plane?The measure of the boundary of a plane or shape is called its perimeter. The perimeter of a plane or shape is the sum of all the sides.
A small rectangle has a length of 6.2 feet and width of 1.8 feet. The parameter of this triangle is,
[tex]P_s=6.2+1.8\\P_s=8\rm\; ft[/tex]
The small rectangle has a length of 6.2 and the larger rectangle has a length of 12.4 feet. Thus the scale factor of enlargement is,
[tex]r=\dfrac{12.4}{6.2}\\r=2[/tex]
The perimeter of the original rectangle is 16 feet and scale factor is 2. Thus, the perimeter of the enlarged rectangle is,
[tex]P_l=2\times16\\P_l=32\rm\; ft[/tex]
The small rectangle has width of 1.8 feet and scale factor is 2. Thus, the width of the larger rectangle is,
[tex]w_l=1.8\times2\\w_1=3.6\rm\; ft[/tex]
Hence, the perimeter of the enlarged rectangle is 32 ft and the width of the larger rectangle is 3.6 ft.

A square box has a height of 21 inches. What is the measure of the
diagonal of the box? Round to the tenths place.
Answer:
29.7 inches
Step-by-step explanation:
if it's a square box we can assume that all sides are equal. so the width is also equal to 21 inches.
to find the diagonal we use the pythagorean theorem which states that a^2 +b^2 =c^2 where c is the diagonal and (a) and (b) are 21
so diagonal is the root of
21^2 + 21^2
answer is 29.7

Answer:
[tex]y\geq 2x+3[/tex]
Step-by-step explanation:
the gradient of a line is found by using the formula [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1} }[/tex]
so we get [tex]\frac{5-3}{1-0}=\frac{2}{1} =2[/tex]
the y-intercept is where the line crosses the y-axis which is simply 3
so the equation of this line is [tex]y=2x+3[/tex] in the form [tex]y=mx+c[/tex]
but the question is asking for an inequality, specifically above the line so we get [tex]y\geq 2x+3[/tex]
Slope:-
[tex]\\ \tt\Rrightarrow m=\dfrac{-3-3}{-3}=2[/tex]
Equation of line in point slope form
[tex]\\ \tt\Rrightarrow y-3=2x[/tex]

Put (0,0)
2(0)+3=3>0Hence the inequality is

Find x and show work.
Answer:
X is 2 2+2= 4 plus 4 = 8
Step-by-step explanation:
Hoped this helped
Answer:
x = 2
explanation:
2x + 4 = 8
subtract 4 from both sides
2x + 4 -4 = 8 -4
2x = 4
divide both sides by 2
2x/2 = 4/2
x = 2
Recheck:
2x + 4 = 8
2(2) + 4 = 8
8 = 8
Hence proved the solution is correct.

May you please do number 11. I don’t know how to do it.
Answer:
11.) 105 degrees
12.) 50 degrees
13.) 55 degrees
Step-by-step explanation:
11.) <EFG is a straight angle (180 degrees) so 180-75=105
12.) <FGC is a right angle (90 degrees) so subtract 40 and you get 50 degrees
13.) Sum of angles in a triangle is 180 degrees. Since we already know 2 angles, just subtract from 180. 180-75-50=55 degrees

Use the triangle to find each of the six trigonometric functions of _. Show all work
Answer:
you need to find that missing side... so (A squared) x (B squared) = (C squared)
A squared = 5
B squared is missing
C squared = 6
A=25
C=36
36-25= B squared....... B= (square root of 11)
now you need to plug in the numbers for the 6 trig equations...
sin0 = 5/6
cos0 = (square root of 11)/6
tan0 = 5/(square root of 11) which actually equals 5(square root of 11)/11
csc0 = 6/5
sec0= 6/ (square root of 11) which actually equals 6(square root of 11)/11
cot0 = (square root of 11/5

Answer:
$19.07
Step-by-step explanation:
Look at image above...
The total cost of the meal is $19.065.
What is the percentage?In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
A restaurant bill before tax is $15.50.
If the sales tax is 8% and a 15% tip is added.
The total cost of the meal is;
[tex]\rm Total \ cost = Bill \ amount + Sales \ tax + Tip\\\\ Total \ cost = 15.50 + 15.50 \times \dfrac{8}{100} + 15.50 \times \dfrac{15}{100}\\\\ Total \ cost = 15.50+1.24+2.32\\\\ Total \ cost = 19.065[/tex]

Paisley is trying to find the height of a radio antenna on the roof of a local building. She stands at a horizontal distance of 22 meters from the building. The angle of elevation from her eyes to the roof (point A) is 29°, and the angle of elevation from her eyes to the top of the antenna (point B) is 42°. If her eyes are 1.74 meters from the ground, find the height of the antenna (the distance from point A to point B). Round your answer to the nearest meter if necessary.
Using the tangent ratio, the height of the antenna, to the nearest meter, is AB = 8 m.
What is the Tangent Ratio?Tangent ratio is expressed as: tan ∅ = opposite/adjacent (TOA).
The information given has been sketched in the diagram attached below.
Find AC using the tangent ratio. Thus, we would have:
tan 29 = AC/CD
Substitute
tan 29 = AC/22
AC = tan 29 × 22 = 12.2 m.
Find BC using the tangent ratio:
tan 42 = BC/DC
Substitute
tan 42 = BC/22
BC = tan 42 × 22 = 19.8 m.
The height of the antenna, AB = BC - AC = 19.8 - 12.2 ≈ 8 m.
