What is the domain of g?
Answers
Answer:
The domain of g(x) is the set of all real numbers. Also, g(g(x)) is defined for the set of all real numbers. Therefore, the domain of is the set of gg D all real numbers
Step-by-step explanation:
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited

Answers
Answer:
[tex] {x}^{2} + 5x = - 2[/tex]
arrange the equation according to general formula;
General formula: ax² + bx + c = 0
therefore:
[tex] {x}^{2} + 5x + 2 = 0[/tex]
Using the quadratic equation :
[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]
a » 1, b » 5, c » 2
substitute:
[tex]x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 1 \times 2) } }{(2 \times 1)} \\ \\ x = \frac{ - 5± \sqrt{17} }{2} [/tex]
therefore solutions are;
[tex]{ \boxed{ \boxed{x_{1} = \frac{ - 5 + \sqrt{17} }{2} }}} \: \: and \: \: { \boxed{ \boxed{x_{2} = \frac{ - 5 - \sqrt{17} }{2} }}}[/tex]

Working alone, Dan can paint a fence in ten hours. One day his friend Natalie helped him and it only took 4.12
hours. How long would it take Natalie to do it alone?
Answers
===========================================================
Explanation:
Let's say there are 1000 boards to be painted.
Working alone, Dan can paint 1000 boards in 10 hours, so his unit rate is 1000/10 = 100 boards per hour.
In 4.12 hours, he gets 4.12*100 = 412 boards painted. There are 1000-412 = 588 boards left which Natalie takes care of. This is when the two are working together.
Her unit rate is (588 boards)/(4.12 hours) = 142.718447 boards per hour. That value is approximate.
We multiply her unit rate by some unknown amount of time x, and this product will be the 1000 boards we started with. This way she would get the job down by herself.
So the equation we need to solve is
142.718447x = 1000
--------------------
We divide both sides by 142.718447 to fully isolate x.
142.718447x = 1000
x = 1000/(142.718447)
x = 7.006803
That value is approximate.
If we round to the nearest whole number, then x = 7
So it takes about 7 hours for Natalie to get the job done if she works alone.
-------------------

Step-by-step explanation:
Adjacent angles are angles that share a common side and vertex. So, find the angles that share one side. In this case, the two sides of the angle <XOY are OX and YO. Remember when naming an angle that it should be one side, the vertex, the last side. So, the 2 adjacent angles are <UOX and <YOZ because they each share one common side and vertex.

Find the unknown sizes of the angle
please answer fast
Answers
The opposite angles formed on an intersecting line are equal.
Here,
angle y + 10 = angle 2y - 80
Now,
y + 10 = 2y - 80
10 + 80 = 2y - y
90 = y
Therefore,
The angle y + 10 measures 100°.
Also, angle 2y - 80 measures 100°.
The other two angles measure 80° each.
