Step-by-step explanation:
Not a function
In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.
For
x2+y2=9
(for example)
x=0
there are two values for y (namely +3 and −3) which satisfy the equation
If you plug this graph into a calculator, you will find that it is a graph of a circle.
Circles have the formula x2+y2=r2 if they are centered at the origin.
From that, we can find that the radius is 3, and it is centered at the origin.
To find the domain and range, we just find the largest and smallest x and y values.
Since the radius is 3, and the graph is centered at the origin, the largest x value is 3. Similarly, the smallest x value is -3.
The domain is −3≤x≤3
We can use the same thing for the range. The radius is 3, so the largest and smallest values of the y will be 3 and -3.
The range is -3≤y≤3
Answer:
See below
Step-by-step explanation:
6. Look at the graph of the equation x^2+y^2=8. Give its domain and range.
Both domain and range are: (- √8, √8) or (-2.828, 2.828)7. Use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.
The vertical line test. If more than one point is crossed on the graph by a vertical line, then the relation is not considered to be a function.8. Is there any value(s) of the domain of x^2+y^2=8 that passes the vertical line test? If so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.
There are two points - 2.828 and 2.828 that pass the vertical line test but all the other points don't, therefore this relation is not a functionRelated Questions

I need help with slope
Answers
Answer:
Step-by-step explanation:
Slope means x there are many ways to find the slope like using the slope formula y2-y1/x2-x1 or using rise over run
Hope this help :)
Answer:
Rise over run
Step-by-step explanation:
So what the Rise is, is the point on which the line is persicly on point with they grid of your graph / how high also the distance on the y axis. The run is the how far also known as the x axis.
so if we had a slope of 2/3
it would be a posative slope it wod go up 2 and to the right 3 to the next intersection of the y ad the x axis'

You probably forgot to mention the options. After a little research, I was able to get the complete question with the mentioned options you should have mentioned. The potential complete question is:
Ellen plans to leave an 18 percent tip with her $23.75 lunch bill. Which of these expressions could she use to determine her total bill?
Check all that apply.
(1.18)(23.75) 23.75 – [(0.18)(23.75)] 23.75 + [(0.18)(23.75)] (0.18)(23.75)
Answer:
The expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.
Step-by-step explanation:
Total lunch bill = $23.75
As he pans to 18% tip of the total bill, so the expression will be:
[tex]=23.75\:+\:\left(\:18\%\:\:of\:\:23.75\:\right)[/tex]
[tex]=23.75\:+\:\left(\:\frac{18}{100}\:\times \:23.75\:\right)[/tex]
[tex]=23.75\:+\:\left(\:0.18\times \:23.75\:\right)[/tex]
or
[tex]=23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex]
Therefore, the expression [tex]23.75\:+\:\left[\left(0.18\right)\left(23.75\right)\right][/tex] will determine her total bill.

Exercice 2: Un remorqueur tire un bateau à la vitesse de 10 noeuds. La tension du câble est de 2500N, Le câble est parallèle à la trajectoire. Calculer la puissance correspondante. (Une vitesse moyenne de 1 noeud correspond à un parcours de 1 mille marin, soit 1852 m, en 1 heure. D'où : 1 noeud = 1,852 km/h = 0,514 m.S")
Answers
Répondre:
1 285 watts
Explication étape par étape:
La puissance est exprimée selon la formule;
power = travail effectué / temps
Puissance = Force * (distance / temps)
Depuis Vitesse = distance / temps
Puissance = Force * vitesse
Donné
Force = 2500N
Vitesse (en m / s) = 0,514 m / s
Obligatoire
Puissance
Remplacez la formule donnée;
Puissance = 2500 * 0,514
Puissance = 1,285Watts
Par conséquent, la puissance correspondante requise est de 1285 watts

Answer:
a) The vertex will be at (-2, -1), and the parabola will look like a smiley face. 5 points on the parabola would be: (3, 24), (-3, 0), (2, 15), (-1, 0) and (1, 8).
b) The focus will be at (-2, 0), the directrix will be at y = -2, and the axis of symmetry will be at x = -2.
Step-by-step explanation:
a) The vertex (-2, -1) can be found by first setting the parentheses (x+2) equal to zero and solving to get the x value -2, then setting x equal to zero and solving to get the y value of -1.
The parabola will be pointing up on both ends because the equation for it is positive (given 1 multiplied by parentheses) and it has a degree of 2.
The xy table to find the points would look like this:
x | y
3 | 24
-3 | 0
2 | 15
-1 | 0
1 | 8
b) The focus is one unit above the vertex, so the y value increases by 1. The directrix is a line 1 unit below the vertex, so its y value is 1 less than the vertex's. The axis of symmetry is the same as the x value of the vertex with infinite y values.

1. Suppose that during its flight, the elevation e (in feet) of a certain airplane and its timet
in minutes since takeoff, are related by a linear equation. Consider the graph of this
equation, with time represented on the horizontal axis and elevation on the vertical
axis. For each situation, decide if the slope is positive, zero, or negative.
a. The plane is cruising at an altitude of 37,000 feet above sea level.
b. The plane is descending at rate of 1000 feet per minute.
c. The plane is ascending at a rate of 2000 feet per minute.
Answers
Answer:
A:zero
B:negative
C:positive
Step-by-step explanation:
the key words just tell you for A it was cruising B it was negative because descending and C is positive because ascending.
The correct explanation for the slope will be;
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.
What is mean by Slope?
The slope of line is a measure of its steepness.
Given that;
During its flight, the elevation e (in feet) of a certain airplane and its time
in minutes since takeoff, are related by a linear equation.
In the graph, time represented on the horizontal axis and elevation on the vertical axis.
Now,
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
Because the plane is cruising.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
Because the plane is descending.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.
Because the plane is ascending.
Thus, The correct explanation for the slope will be;
a) When the plane is cruising at an altitude of 37,000 feet above sea level, then the slope is zero.
b) When the plane is descending at rate of 1000 feet per minute, then the slope is negative.
c) When the plane is ascending at a rate of 2000 feet per minute. then the slope is positive.

Identity
Answers
Answer:
Multiplicative identity is the property shown by this equation
Step-by-step explanation:
Multiplicative identity is explained as the product of any number and one is that number. Multiplicative identity is a property exhibited by most of the mathematical tools.
Zero and one are the numbers used to simplify equations whereas zero is called the additive identity. If we add any number with zero, it will result in the same in number.
Like that 1 is used in multiplicative identity. More simple example could be 5 ˣ 1 = 5 ., it is the multiplicative identity property
