Answer: About 3.06
Step-by-step explanation:
We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.
Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.
cos(θ) = [tex]\frac{adjacent}{hypotenuse }[/tex]
cos(40) = [tex]\frac{x}{4}[/tex]
0.766 ≈ [tex]\frac{x}{4}[/tex]
3.06 ≈ x
x ≈ 3.06

[tex]p=\dfrac12[/tex][tex]q=-\dfrac13[/tex][tex]r=\dfrac15[/tex]Given expression:
[tex]\dfrac{30pqr(p+q+r)}{(p+q)(p+r)}[/tex]
Substitute given values into given expression:
[tex]\implies \dfrac{30\cdot\dfrac12\cdot-\dfrac13\cdot\dfrac15\left(\dfrac12-\dfrac13+\dfrac15\right)}{\left(\dfrac12-\dfrac13\right)\left(\dfrac12+\dfrac15\right)}[/tex]
[tex]\implies \dfrac{-\dfrac{30}{30}\left(\dfrac{15}{30}-\dfrac{10}{30}+\dfrac{6}{30}\right)}{\left(\dfrac36-\dfrac26\right)\left(\dfrac{5}{10}+\dfrac{2}{10}\right)}[/tex]
[tex]\implies \dfrac{-1\left(\dfrac{11}{30}\right)}{\left(\dfrac16\right)\left(\dfrac{7}{10}\right)}[/tex]
[tex]\implies \dfrac{-\dfrac{11}{30}}{\dfrac{7}{60}}[/tex]
[tex]\implies -\dfrac{11}{30}\times \dfrac{60}{7}[/tex]
[tex]\implies -\dfrac{660}{210}[/tex]

Answer:
{x : x > 5}
Step-by-step explanation:
-4x - 5 < -25
-4x < -20
When dividing/multiplying both sides with a negative number, change the inequality symbol to the opposite direction. e.g. < to > or > to <.
x > -20/-4
x > 5
Hence, the solution set is {x : x > 5}.

Domain: Domain of function is defined by the x-values (Input values) on the graph.
Range: Range of a function is defined by the y-values (output values) on the graph.
x-values are starting from (-3) to infinity.
Therefore, domain of the function will be all real numbers greater than equal to (-3). Option (4) will be the answer.
The domain of the function are all real numbers greater than or equal to -3.
What is function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given is a graph, we need to find domain of the function on the graph,
Domain is the set of all possible inputs or x-values, for which the given function is defined.
The given graph is defined form -3 to positive infinity. The point -3 included in the set of input because there is a closed circle at x=-3.
So, domain of the function are all real numbers greater than or equal to –3.

If n'(x) = 2sin(2x) and n(0) = 0 what is the absolute maximum of n(x) on (0,2-}?
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3.
How to find the absolute maximum of a differentiable function
A function is differentiable in a given interval if and only if its derivative exists for every value of the interval. To determine the absolute maximum of n(x), we need to integrate the given function, apply first derivative and second derivative test and finally evaluate n(x).
First, we integrate n'(x) in terms of x:
n(x) = 2 ∫ sin 2x dx = 2 · (- 0.5 · cos 2x) + C = - cos 2x + C
- cos 0 + C = 0
C = 1
Then, n(x) = 1 - 2 · cos 2x.
Now we proceed to apply first and second derivative tests:
First derivative test2 · sin 2x = 0
sin 2x = 0
2 · x = sin⁻¹ 0
2 · x = π ∨ 2π
x = 0.5π ∨ π
Second derivative testn''(x) = 4 · cos 2x
n''(π) = 4 · cos 2π
n''(π) = 4
There is an absolute minimum for x = π. [tex]\blacksquare[/tex]
n''(0.5π) = 4 · cos π
n''(0.5π) = - 4
There is an absolute maximum for x = 0.5π. [tex]\blacksquare[/tex]
Finally, we evaluate n(x) for x = 0.5π to determine the absolute maximum:
n(0.5π) = 1 - 2 · cos π
n(0.5π) = 3
The absolute maximum of n(x) = 1 - 2 · cos 2x, whose first derivative is n(0) = 0, exists at x = 0.5π on (0, 2π]. The value of the absolute maximum is 3. [tex]\blacksquare[/tex]
RemarkThe statement of the question is poorly formatted and reports several mistakes, correct form is introduced below:

You are considering the two different car loans.
Using the payment table, which loan has the lowest monthly payment?
Loan A has the lower monthly payment
=========================================================
Explanation:
Loan A is at a rate of 6.9% over 5 years. The table says that if you borrowed $100 at this interest rate and time period, then the monthly payment would be $1.98 per month.
However, you are borrowing $17,601 which is 176.01 times greater than 100 since (17601)/(100) = 176.01
So 1.98*176.01 = 348.4998 = 348.50 is the monthly payment of loan A.
------------------
Meanwhile, loan B has an interest rate of 8.9% and lasts for 3 years. Use the table to see that borrowing $100 at this rate and time means the monthly payment is $3.18
The multiplier this time is 162.90 because (16290)/(100) = 162.90
Therefore, 162.90*3.18 = 518.022 = 518.02 is the monthly payment of loan B.
--------------------
To summarize, we have these monthly payments
loan A monthly payment = $348.50loan B monthly payment = $518.02Loan A has the lower monthly payment

The graph is not symmetric, and it has no vertical or horizontal asymptotes.
What is coordinate geometry ?Coordinate geometry is a branch of mathematics that combines algebraic and geometric concepts to study the properties of geometric figures using a coordinate system. It involves representing geometric figures such as points, lines, curves, and shapes in a plane or space using numerical values called coordinates.
According to given information :The graph of the function [tex]f(x)=-3(x+1)^2 (x-3) (x-5)^3[/tex] is a cubic polynomial function with several important characteristics:
Degree: The degree of the function is 7, which means that the graph has 7 x-intercepts.
Symmetry: The function is not symmetric with respect to the y-axis or the origin.
End Behavior: As x approaches negative infinity, the function approaches negative infinity, and as x approaches positive infinity, the function approaches negative infinity.
Zeros: The function has x-intercepts at x = -1, x = 3, and x = 5. The intercept at x = -1 has a multiplicity of 2, while the intercepts at x = 3 and x = 5 have a multiplicity of 3. This means that the graph touches the x-axis at x = -1 and bounces off at x = 3 and x = 5.
Turning Points: The function has two turning points, one at x = -1 and one at x = 3. The turning point at x = -1 is a local maximum, while the turning point at x = 3 is a local minimum.
Behavior near Zeros: Near each of the x-intercepts, the function changes direction. At x = -1, the function changes from decreasing to increasing. At x = 3 and x = 5, the function changes from increasing to decreasing.
Vertical Asymptotes: The function has no vertical asymptotes.
Horizontal Asymptotes: The function has no horizontal asymptotes.
Intercepts: The y-intercept of the function is at y = 0.
Overall, the graph of the function [tex]f(x)=-3(x+1)^2 (x-3) (x-5)^3[/tex] is a complicated cubic polynomial with multiple x-intercepts, turning points, and changing directions near the intercepts.
Therefore, the graph is not symmetric, and it has no vertical or horizontal asymptotes.

Answer:
K = (-5, 14)
Step-by-step explanation:
For writing equations of parallel and perpendicular lines, it is convenient to start with equations in general form:
ax +by +c = 0
Rewriting the given equations, we have ...
y = 1/2x -1
x -2y -2 = 0 . . . . . line d
y = -3x +2
3x +y -2 = 0 . . . . . line d'
__
A parallel line will have the same coefficients, but a constant appropriate to the required point on the line.
Parallel to d' through A(-1, 2):
3(x -(-1)) +(y -2) = 0
3x +y +1 = 0 . . . . . . . . simplify
__
A perpendicular line will have the coefficients swapped and one of them negated. Again, the constant is appropriate to the required point.
Perpendicular to d through B(3, -2):
2(x -3) +(y -(-2)) = 0
2x +y -4 = 0 . . . . . . . . simplify
__
The solution to this system of equations can be found by subtracting the second equation from the first:
(3x +y +1) -(2x +y -4) = (0) -(0)
x +5 = 0
x = -5
Substituting into the second equation gives ...
2(-5) +y -4 = 0
y -14 = 0
y = 14
The coordinates of point K are ...
K = (-5, 14)
_____
Additional comment
The general line through the origin ...
ax +by = 0
can be translated to go through point (h, k) by the usual method for translating functions. The variable x is replaced by (x -h), and the variable y is replaced by (y -k). Using the general form equation means we can keep the variables and constants all on the same side of the equal sign, saving a bit of work and confusion.
a(x -h) +b(y -k) = 0 . . . . . . line through point (h, k)
__
The graph is drawn by a geometry program capable of drawing parallel and perpendicular lines through given points. It confirms the equations and th solution.
