Which statement describes the graph of this polynomial function?
f(x)= x4 + x3 - 2x2
Answer:
NOT c
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The graph crosses the x-axis at x = 2 and x = –1 and touches the x-axis at x = 0.
The graph touches the x-axis at x = 2 and x = –1 and crosses the x-axis at x = 0.
The graph touches the x-axis at x = –2 and x = 1 and crosses the x-axis at x = 0.

Imagine that your team has been assigned by a construction company to measure the dimensions of an empty lot in a subdivision. Briefly give examples of the 6 types/sources of errors described above and explain what you would do to minimize them.
Answer:
All explained below.
Step-by-step explanation:
The sources of errors are;
1) Instrumental Errors: This could be as a result of wrong calibration of equipment.
2) Observational Systematic errors: An example of this is parallax error while taking a reading.
3) Environmental random errors: In this type of error, a slight change in the temperature of humidity in the lot could possibly affect the accuracy of the measurement.
4) Observational random errors: This refers to errors gotten when the values are incorrectly read or incorrectly interpolated.
5) Environmental systematic errors: An example of this is that the current supplied to the instrument taking the reading may be low. Thus, this may affect effective reading.
6) Theoretical systematic errors: This could arise from over simplification of the experimental model. An example of this is that the experiment might require a totally frictionless surface which may not be achievable. And this will lead to wrong measurement.
Minimizing the errors:
1) Instrumental Errors can be minimized by ensuring proper calibration of equipment before use.
2)Observational Systematic errors can be minimized by ensuring readings are not taken at an angle.
3)Environmental random errors could be minimized by carrying out the experiment in a relatively good laboratory under fair weather conditions.
4)Observational random errors can be minimized by ensuring that the results from the readings are properly collated and the rightly interpolated as the case may be.
5)Environmental systematic errors can be minimized by ensuring stable power source to the instrument being used for the reading.
6)Theoretical systematic errors could be minimized by taking an average of at least 3 tests result to get a fair representation of the final result.

While hiking, Sandra went up 120 meters. If Sandra started at 800 meters above sea
level, what is her elevation now?
The Answer:
If Sandra started at 800 meters and went up 120, the answer would be 920.
Step-by-step explanation:
First, simply add 800 meters, which is what she started with. Next, since she has gone up 120 meters since then, and the question is asking us what her elevation is NOW, you can add 800 + 120 to get 920. This question is solved by using addition.

What is the equation of the axis of symmetry?
Easy please help
Answer:
[tex]-\frac{b}{2a}[/tex] is the equation for axis of symmetry.
Step-by-step explanation:
b is the second part of the quadratic equation and a is the first part.
For example, [tex]2x^{2} +6x + 4[/tex]
a is 2 and b is 6.
Plug in those values into the equation and then you get the axis of symmetry.

Answer:
a)M5=40º
b)M2=140º
c)M2 and M5 are supplementary angles
d)M2 and M5 are same side interior angles
e) A||B
Step-by-step explanation:
Remember that same side interior angles are the angles that are located on the same side of a straight line that cuts through two parallel lines, and these angles are supplementary, meaning that the sum of both of them will always be 180º. So by stating that M5 and M2 add up to 180º and they are on the same side of a straight line cutting through two straight lines we can prove that those two lines are parallel.

What set of transformations could be applied to rectangle ABCD to create A″B″C″D″?
'Rectangle formed by ordered pairs A at negative 4, 2, B at negative 4, 1, C at negative 1, 1, D at negative 1, 2. Second rectangle formed by ordered pairs A double prime at negative 4, negative 2, B double prime at negative 4, negative 1, C double prime at negative 1, negative 1, D double prime at negative 1, negative 2.
Reflected over the x‒axis and rotated 180°
Reflected over the y-axis and rotated 180°
Reflected over the x‒axis and rotated 90° counterclockwise
Reflected over the y-axis and rotated 90° counterclockwise
Answer:
B. Reflected over the y-axis and rotated 180°
Step-by-step explanation:
A(-4, 2) Reflected over the y-axis (x, y) → (-x, y) → A'(4, 2)
A'(4, 2) → rotated 180° (x, y) → (-x, -y) → A"(-4, -2)
The set of transformations that can be applied to ABCD, to create A″B″C″D″ is a reflection over the y-axis, followed by a rotation of 180°
What is composite transformation?"It is the production of the image of a figure through two or more transformation."
What is reflection?"It is a geometric transformation where all the points of an object are reflected on the line of reflection."
What is rotation?"It is a transformation in which the object is rotated about a fixed point."
For given question,
The rectangle ABCD is formed by ordered pairs A at (-4, 2) , B at (-4, 1), C at (-1, 1), D at (-1, 2)
The rectangle A″B″C″D″ is formed by ordered pairs A" at (-4, -2), B" at (-4, -1), C" at (-1, -1) , D" at (-1, -2)
We can observe that the coordinates of ABCD are of the form (-x, y) where x, and y, are positive numbers
The form of the ordered pair of the vertices of the A″B″C″D″ is (-x, -y)
The coordinates of the point (-x, y) after reflection over y-axis would be of the form (x, y)
And after rotation of 180° the coordinates would be (-x -y)
Therefore, the set of transformations that can be applied to ABCD, to create A″B″C″D″ is a reflection over the y-axis, followed by a rotation of 180°

Help! Best answer will get brainiest
Answer:
x=20
Step-by-step explanation:
Complementary means =90 degrees, so with that being said, you need to write the equation as follows:
2x+10+x+20=90
Then add like terms:
3x+30=90
Subtract 30 from both sides (30 and 90)
3x=60
Divide both sides by 3
x=20

The perimeter of a triangular garden is 78 feet. Find the length of the three sides if the middle length side is 3 feet greater than twice the length of the smallest side, and the longest side is 3 feet less than 3 times the length of the smallest side.
Answer:
36, 29 and 13
Step-by-step explanation:
Let 'a' be the longest side.
Let 'b' be the middle side.
Let 'c' be the smallest side.
From the question given above,
The perimeter of a triangular garden is 78 feet. This can be written as:
Perimeter = a + b + c
78 = a + b + c ...... (1)
The middle length side is 3 feet greater than twice the length of the smallest side. This can be written as follow:
b = 2c + 3 ...... (2)
The longest side is 3 feet less than 3 times the length of the smallest side. This can be written as follow:
a = 3c – 3 ..... (3)
Summary:
78 = a + b + c ...... (1)
b = 2c + 3 ...... (2)
a = 3c – 3 ..... (3)
Substitute the value of a in equation
3 and the value of b in equation 2 into equation 1
78 = a + b + c
b = 2c + 3
a = 3c – 3
78 = (3c – 3) + (2c + 3) + c
78 = 3c – 3 + 2c + 3 + c
78 = 3c + 2c + c – 3 + 3
78 = 6c
Divide both side by 6
c = 78/6
c = 13
Substitute the value of c into equation 2 and 3 to obtain the value of b and a respectively
b = 2c + 3
c = 13
b = 2(13) + 3
b = 26 + 3
b = 29
a = 3c – 3
c = 13
a = 3(13) – 3
a = 39 – 3
a = 36
Therefore, the length of the three sides are: 36, 29 and 13
