The domain (input values) and range (output values) of the function is, Domain: (Negative infinity, infinity), Range: (0, infinity).
What is domain and range of function?Domain of a function is the set of all the possible input values which are valid for that function.
Range of a function is the set of all the possible output values which are valid for that function.
Given information-
The function given in the problem is,
[tex]y=f(x)\\y=h(x)\\y=g(x)\\y=k(x)[/tex]
As domain of a function is the set of all the possible input values which are valid for that function. Thus the function should accept all the values for the given function.
Here in the given function the function is takes the input for all the real number form positive to the negative infinite. Thus the domain of the function is,
Domain: (-∞, ∞).
Range of a function is the set of all the possible output values which are valid for that function.
Here the output for the given function gives the positive values to the infinite. thus the range of the function is,
Range: (0, ∞).
Thus, the domain and range of the function is, domain: (Negative infinity, infinity), range: (0, infinity).

Given the lengths of two sides of a triangle. write an inequality to indicate between which two numbers the length of the third side must fall. 8 and 13. 11.5 and 23.6. 22 and 15. 13.2 and 6.7. and 23 and 44. answer for each of the problems like __< 3 rd side<__
Answer:
1. 5 <3rd side<21 2. 12.1<3rd side<35.1
Step-by-step explanation:
Answer:
1: 5 < 3rd side <21
2: 12.1< 3rd side < 35.1
3: 7<3rd side < 37
4: 6.5 < 3rd side 19.9
5 : 21 < 3rd side 67
Step-by-step explanation:
For example you have 5 and 10
you take 5 + 10 to get your side and you do
the biggest number - the smaller number to get the _ <3rd.
So if you have 5 and 10 you know that it would be 5 < 3rd side < 15
7. Arrival of the Normandy Train
Claude is waiting to meet the train from Normandy at Gare Saint-Lazare in Paris. He
tells Marie the hour of the train's arrival and he tells Jean at which minute it arrives. He
also tells them both that the train arrives between 0600 and 1000.
They consult the timetable and find the following services between those times:
0620, 0639, 0650; 0717, 0746; 0825, 0839; 0917, 0925, 0950.
Marie then says, “I don't know when Claude's train arrives, but I'm sure that neither does
Jean."
Jean replies, “I didn't know his train, but now I do."
Marie responds, “Now I do as well!"
When is Claude's train and how do you know?
Answer:
0839
Step-by-step explanation:
First of all, let's cancel 0620 and 0746, because they dont have any other number that has the same last 2 digits as them. Jean would've immediately known the train number if it was one of these two.
Now, when Marie says "I'm sure that neither does Jean", it means she is guaranteed Jean doesn't know the train number. It mean she couldnt've gotten 06 or 07, as 0620 and 0746 have it.
We're left with 0825,0839,0917,0925 and 0950
When Jean replies he knows the train number, it means he couldnt've gotten 25, as it's repeated.
And when Marie responds she knows as well, she couldnt've gotten 09, as it's also repeated.
We can cancel 0825,0917,0925 and 0950
So, the train number is 0839

given the table, write the equation in the slope-intercept form
Answer:
y=2x+6
Step-by-step explanation:
Slope intercept form is:
y=mx+b
m: slope
b: y-intercept
We can start by solving for the slope. The equation for slope is:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in any two x, y pairs from the table into the equation. Let's use (-3, 0) and (0, 6):
[tex]Slope=\frac{6-0}{0-(-3)}=\frac{6}{0+3}=\frac{6}{3}=2[/tex]
y=2x+b
Now, we can plug in a x, y pair from the table in for x and y to solve for the y-intercept. Let's use (0, 6):
y=2x+b
6=2(0)+b
6=0+b
b=6
Therefore the equation is:
y=2x+6

Now let's look at the rest of the sentence minus the phrase we just used.
The square of the sum of x and 5.
The sum of x and 5 goes first,
x + 5
and since we are looking for the square of x + 5:
(5 + x)^2
therefore,
[tex]y = (5 + x)^2[/tex]

candy had some money. she bought a drink for £1.45 and a piece of cake for £1.20 she now has two thirds of her money left. how much money did candy to start with? i suck at fraction
The amount of money Candy started with after spending on drinks and cakes is £7.95
How to find the amount of money she started with?She bought a drink for £1.45 and a piece of cake for £1.20.
She has two thirds of here money left.
Let the money she has initially = x
Therefore,
2 / 3 x = x - 1.45 - 1.20
2 / 3 x = x - 2.65
subtract x from both sides
2 / 3 x - x = - 2.65
2x - 3x / 3 = - 2.65
- x / 3 = - 2.65
cross multiply
-x = - 2.65 × 3
- x = -7.95
x = £ 7.95
Therefore, Candy started with £7.95

graph the equation.
- 5/4 (x-1)(x+3)
Answer:
Step-by-step explanation:
So, to graph a parabola we must have at least 3 points, the x intercepts and the turning point. Currently the equation is in x intercept form which means that we know straight away (assuming the equation =0) that the x intercepts are:
(1,0) and (-3,0)
Now we have to find the turning point and we can do this by putting the equation into turning point form:
-5/4([tex]x^{2} +2x-3[/tex])
-5/4(([tex](x+1)^{2} -3-1[/tex])
-5/4[tex](x+1)^{2}+5[/tex]
Now we can figure out the turning point which is:
(-1,5)
Graph those three points and you should get a parabola shape

A. MO/SA = OE/AW
Step-by-step explanation:
A. would be your correct answer because if you analyze the triangles you can see that the similar sides would be MO and SA, OE and AW, and ME and SW. In all of the answers, they compare sides that arent similar like OE/SW. However, in the first answer, the sides they compare are indeed similar, as you can see by what I listed above. These sides are similar because they are both the adjacent and opposite sides of each triangle.

The sides of One World Trade Center in New York City form
eight isosceles triangles, four of which are 200 ft long at their base BC. The
length AC of each sloping side is approximately 1185 ft.
The value of ∠BAC in the isosceles triangle is 9.7°
Cosine rule
Cosine rule is used to show the relationship between the sides and angles of a triangle. It is given by:
a² = b² + c² - 2bc*cos(A)
where a, b, c are the sides of the triangle and A, B, C are the angles opposite the sides.
AB = AC = 1185 (isosceles), BC = 200, let ∠BAC = x°, hence:
200² = 1185² + 1185² - 2(1185)(1185)cos(x)
2(1185)(1185)cos(x) = 2808450
cos(x) = 0.9857
x = 9.7°
The value of ∠BAC in the isosceles triangle is 9.7°

The right-angle triangle shows this condition. Then the value of angle x is 30.80°.
What is a right-angle triangle?It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.
The expression is given as
[tex]\rm x = \rm tan ^{-1} \dfrac{3.1}{5.2}[/tex].
We know that the tangent is the ratio of the perpendicular to the base of the right-angle triangle.
x will be the angle and the opposite side of the x will be the perpendicular of lengths 3.1 and 5.2 will be the base of the that is along the angle x.
