is x to the second power plus y to the second power linear or non linear?
Answer:
No, but the reason depends. Pick the one that applies to the question.
Are we talking function in two variables, ie [tex]z=f(x,y) = x^2+y^2[/tex] : in this case no, the surface you generate is a paraboloid - think the satellite dishes you use for telecomunications. not linear anyways.
Are we talking about [tex]x^2+y^2=0[/tex]? This has only one solution, which is the origin (0;0). in fact if you solve for either of the two you will get [tex]x^2=-y^2[/tex]. Now LHS is greater or equal than zero, RHS is lesser or equal than zero - the whole thing is true only if they are both 0. But still, not linear.
Are we talking about [tex]x^2+y^2 = r[/tex] with [tex]r>0[/tex] (since if it was we would be again at an absurd, something clearly non-negative is equal to a negative number)? Again, non linear, they are circles of radius [tex]\sqrt r[/tex] centered on the origin.
Find a trinomial for the area of the rectangular rug shown on the right whose sides are x+2 feet and 3x-1 feet.
The trinomial for the rectangular rug is 3x² + 5x - 2
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
A trinomial is a polynomial with three terms.
The area of a rectangle = length * width
Area of rectangle = (x + 2) * (3x - 1) = 3x² + 6x - x - 2
Area of rectangle = 3x² + 5x - 2
The trinomial for the rectangular rug is 3x² + 5x - 2

Select from the drop-down menus to correctly complete the statement.
The slope is (), which means that the plant by () every day.
[Graph showing a line, extending from zero zero to seven three point five. There are points on the line at zero zero, two one, four two, and seven three point five. The vertical axis is labeled Growth and the horizontal axis is labeled Time.]--[This is shown in the image connected to this question]
{THIS IS FOR ANYBODY WHO NEEDS HELP!! I DO KNOW THE ANSWER! I'll be putting it in the answers, too.}
Answer:
The slope of the line is 2/3. In context of plant growth, every 3 days, the plant grows 2 inches.
Step-by-step explanation:
To find slope, you count the distance between y-values and x values. You then get a fraction of y over x.

The slope of the graph is 1/2, which means that the plant growth 1 inches in every 2 days.
What is Equation of line?
The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The points on the graph are (2, 1) , (4, 2) and (7, 3.5).
Now,
Since, Slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is,
⇒ m = (y₂ - y₁) / (x₂ - x₁)
Thus, The Slope of the line passing through the points (2, 1) and (4, 2) is,
⇒ m = (y₂ - y₁) / (x₂ - x₁)
⇒ m = (2 - 1) / (4 - 2)
⇒ m = 1 /2
Thus, The slope of the graph is 1/2, which means that the plant growth 1 inches in every 2 days.

what is the perimeter, in grid units, of a regular octagon that has one side with endpoints (-4, -3) and (-4, 8)
Answer:
88
Step-by-step explanation:
Let's find the length of one side. The perimeter will be 8 times that since it's a regular octagon.
[tex]d= \sqrt{(-4+(-4))^2+(8-(-3))^2} = \sqrt{0^2+(11)^2}= 11[/tex]
Perimeter has to be [tex]8\times 11 = 88[/tex]

xy - 20 OVER x + 5; if=-9 and y = 8
Answer: 23
Step-by-step explanation:
okay so if x = -9 and y = 8 you need to place it into the equation like so
-9x8-20 OVER -9+5
then it should be calculated :
-72 - 20 OVER -9 + 5
and calculate it again :
-92 OVER -4
and simplify your answer by dividing it since it’s a fraction (OVER)
-92 divided by -4 is 23.

The sum of a number and negative eleven is negative sixteen. Which of the following is the number?
Answer:
n = -5
Step-by-step explanation:
Let n be the unknown number
n+ (-11) = -16
Add 11 to each side
n+-11+11 = -16+11
n = -5
Answer:
- 5
Step-by-step explanation:
let n be the number , then
n + (- 11) = - 16 , that is
n - 11 = - 16 ( add 11 to both sides )
n = - 5

Answer:

Step-by-step explanation:

=> -1 [ i² . i ]
=> -1 [ (√-1)² . i ]

[tex](-i)^3 = (-1)^3\times i^3 = -1 \times i^2\times i= (-1)\times(-1)\times i=1i[/tex]
Geometric explanation: In the complex plane you can think "multiplying by i" as "rotate 1/4 counterclockwise". [tex](-1)^3[/tex] is a real number, and it's simply [tex]-1[/tex]. Rotate that ccw once, you're at [tex]-i[/tex]. Again, and you're at 1. third time (is really the charm!) you end up at [tex]i[/tex].
Polar explanation Courtesy of euler's identity.

Answer:
7
Step-by-step explanation:
To solve this problem, find the greatest common factor of the numbers representing the numbers of apples and pears respectively.
Each box will contain 3 pears and 4 apples.
And total number of fruits in each box will be 7 fruits.
It's given in the question,
Blake has 64 apples and 48 pears with him.
He has to put equal numbers of each fruit in a box.
To find the greatest number of fruits he can put in a box we will find the greatest common factor (GCF) of the given numbers first.
Therefore, greatest common factor of these numbers = =
GCF of these numbers tells about the number of boxes that can be prepared.
Now the number of pears that can be put in each box =
And the number of apples in each box =
Therefore, each box will contain 3 pears and 4 apples.
And total number of fruits in each box = 3 + 4 = 7 fruits.

which of the following lines is parallel to 2y=3x-1?
a. y = 1/2x - 1
b. 2y = x - 3
c. 4y = 6x + 8
d. y = 3x + 4
e. 3y = 2x - 3
Answer:
c. 4y=6x+8
Step-by-step explanation:
For lines to be parallel, they must have the same slope. To solve this problem, we need to isolate the y on one side of the equation (putting the equation into slope intercept form).
The equation itself must be divided by 2 to do that. We end up with y=1.5x-0.5. We need to find another equation that has 1.5 as the slope.
b. y=0.5x-1.5
c. y=1.5x+2
d. y=3x+4
e. y=2/3x-1
As we can see, the only other equation with a slope of 1.5 is C. Therefore, C is our answer.
Find the value of y. Only type the "number."

The triangle is a right triangle so use the Pythagorean theorem:

What is the approximate average rate of change over the interval [10, 30]?
A.
-6.05 degrees per minute
B.
-1.05 degrees per minute
C.
-41.84 degrees per minute
D.
-2.09 degrees per minute
9514 1404 393
Answer:
D. -2.09 degrees per minute
Step-by-step explanation:
The average rate of change is the change in temperature divided by the change in time:
m = (T(30) -T(10))/(30 -10)
= ((15 +155 e^(-30·0.02)) -(15 +155 e^(-10·0.02))/20
= (155/20)(e^-0.6 -e^-0.2) ≈ -2.09 . . . degrees per minute
