The solution to f(x)=g(x) is 0. Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, f(x)=g(x)
f(x)=-(x+2)(x-2) and g(x)=2|x+2|
Now, -(x+2)(x-2)=2(x+2)
-(x-2)=2
x-2=-2
x=-2+2
x=0
Therefore, option B is the correct answer.

Let k be a constant. Compute d/dx [In(kx)] in two ways. Using the Chain Rule, first decompose y = ln(kx) into an outside and inside function.
Outside function (in terms of u): y = __________
The differentiation using the chain rule gives:
[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]
How to differentiate a logarithmic function?
Remember that:
[tex]ln(x) = \int\limits {\frac{1}{x} } \, dx[/tex]
Now, we want to derivate ln(kx) where k is a constant, the problem tells us to use the chain rule, so we define two functions:
g(x) = ln(x)f(x) = kxThen we have:
g(f(x))
Remember that the chain rule says that:
[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x)[/tex]
In this case:
g'(x) = 1/xf'(x) = kThen:
[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]

The exterior angle of a regular polygon is an 1/8 of the interioris angle How many sides does the regular polygon have ?
Answer:
18 sidesStep-by-step explanation:
We know the interior and exterior angles are supplementary.
Let the exterior angle be x, then the interior angle is 8x.
We have:
x + 8x = 1809x = 180x = 20We now have the exterior angle measure and we know the sum of all of them is 360°.
Find the number of sides:

Physics vectors component
Step-by-step explanation:
Componets of a vector are
[tex]x = r \cos(x) [/tex]
[tex]y =r \sin(x) [/tex]
The vector of F1 has a angle of 30 and radius of 30 n so the component are
[tex]x = 30( \cos(30) ) = {15 \sqrt{3} }[/tex]
[tex]y = 30 \sin(30) = 15[/tex]
F2 is a 90 degree so
[tex]x = 20 \cos(90) = 0[/tex]
[tex]y = 20\sin(90) = 20[/tex]
F3 is a 240 degree so we have
[tex]x = 35( \cos(240) ) = - 17.5[/tex]
[tex]y = 35 \sin(240) = - 17.5 \sqrt{3} [/tex]
F4 is 310 angle so we have
[tex]x = 40 \cos(310) = - 21.01[/tex]
[tex]y = 40 \sin(310) = 34.04[/tex]

In how many ways can 3 oaks, 4 pines, and 2 maples be arranged along a property line if one does not distinguish among trees of the same kind?
Total number of ways to arrange the given trees is equals to 24ways.
What is combination?
" Combination is defined as total number of ways arrangement made without considering the order."
Formula used
Fundamental principle of counting
First group has 'm' objects
second group has 'n' objects
Total number of ways objects can be arranged =m × n
According to the question,
Number of oak trees = 3
Number of pines tree = 4
Number of maples trees = 2
Substitute the given values in the formula we get,
Total number of ways to arrange the given trees = 3 × 4 × 2
= 24ways
Hence, total number of ways to arrange the given trees is equals to 24ways.

Which of the following rational functions is graphed below?
answer I need a picture please
The graph given below is the rational function y = 1/(x + 1).
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
In the case of the function y = 1/(x + 1), the numerator is a constant function, which means that the function has a horizontal asymptote at y = 0.
The denominator, x + 1, is a linear function, which means that the function has a vertical asymptote at x = -1.
Therefore, the graph of the function will have a shape that is similar to a hyperbola.
Thus,
The graph given below is the rational function y = 1/(x + 1).

Answer:
10 CDs
Step-by-step explanation:
First, let's round the cost of each CD to the nearest whole number.
6.98 ≈ 7.00The closest multiple of 7 to 75 is 77.
Then, it would make sense that Sean can buy 11 CDs. However, he has a little bit under 77 dollars, so he can only buy 10 CDs.(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)

Blake is working his way through school. He works two part-time jobs for a total of 22 hours a week. Job A pays $5.70 per hour, and Job B pays $7.30 per hour. How many hours did he work at each job the week that he made $141.40.
Answer:
Job A= 12hrs and Job B= 10hrs
Step-by-step explanation:
first u need to make 2 equations, with 2 variables and the pay per hour for both jobs and let the first equal to the total pay at the end of the week
5.7x + 7.3y = 141.4
then the 2nd equation, let it equal to the total hours worked:
x + y = 22
you then make one of the variables the subject of the formula:
x= 22 - y
and substitute that formula into the first equation you would've made:
5.7(22-y) + 7.3y = 141.4 in this instance you then solve for y:
where y= 10hrs
given that y=10 you can then substitute it into either of the 2 equations:
x+y=22
x= 22-y
x= 22 - 10
x= 12hrs
therefore stating that Blake worked 12 hrs at job A and 10 hrs at job B

According to reports, 30% of American adults have chronic insomnia. If 3 American adults are chosen at random, what is the probability that all 3 have chronic insomnia?
The probability that the three people have chronic insomnia is the likelihood of people having chronic insomnia
The probability that the three people have chronic insomnia is 0.027
How to determine the probabilityThe proportion of people with chronic insomnia is given as:
p = 30%
Given that three people are selected, the probability that the three people have chronic insomnia is calculated as:
[tex]P(3) = p^3[/tex]
So, we have:
[tex]P(3) = (30\%)^3[/tex]
Evaluate the exponent
[tex]P(3) = 0.027[/tex]
Hence, the probability that the three people have chronic insomnia is 0.027
