find the zeros of f(x)= x⁴-2x³+10x²-18x+9, given a zero at x=1
Answer: f(1)=0
Step-by-step explanation:
replace x by 1
[tex]f(1)=1^{4}-2(1)^{3}+10(1)^{2}-18(1)+9[/tex]
f(1)= 1-2(1)+10(1)-18+9
f(1)= 1-2+10-18+9
f(1)= 1+10+9-2-18
f(1)= 20-20
f(1)= 0
When you subtract a number, you get the same result as when you add the opposite of that number. Why?
Step-by-step explanation:
Well, the opposite of a number is the same number with the opposite sign. For example, the opposite of -1 is 1.
So, say we have an equation where we're subtracting a number, for example, 2-1, which obviously equals 1. Now, if we add the opposite of 1 to 2, we get the equation 2+(-1) which still equals 1.
I hope this helps!

If PQR ≈ STU complete each part
Answer:
3 = 21 degrees
5 = 21 degrees
1 = 60 degrees
2 = 39 degrees
4 = 39 degrees
Step-by-step explanation:
This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.
Then, 138 degrees + x * 2 = 180 degrees.
x * 2 = 42 degrees
x = 21 degrees
So 3 and 5 are each 21 degrees
If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.

Question 12 (1 point) Saved An angle measuring 28.3 radians is drawn in standard position? In what quadrant will the terminal side of this angle lie? Express your answer as a Roman numeral. I III IV
Answer:
Answer: III
Step-by-step explanation:
Quadrants
Given an angle in degrees, if its value is:
Between 0° and 90°, it lies in the first quadrant ( I )
Between 90° and 180°, it lies in the second quadrant ( II )
Between 180° and 270°, it lies in the third quadrant ( III )
Between 270° and 360°, it lies in the fourth quadrant ( IV )
We are given an angle of 28.3 radians. Converting to degrees:
[tex]28.3*180/\pi=1621^\circ[/tex]
To convert the angle to its standard position, we divide it by 360° and take the remainder:
1621/360 = 4 (integer part)
Remainder= 1621 - 4*360 = 181°
Since its value is between 180° and 270°, it lies in the third quadrant ( III )

In the diagram, ∠AOB and ∠COB form a linear pair. Which statement must be true about the angles?
A. ∠AOB and ∠COB are supplementary to each other.
B. ∠AOB and ∠COB are supplementary to the same angle.
C. ∠AOB and ∠COB are complementary to each other.
D. ∠AOB and ∠COB are complementary to the same angle.
Please give me a serious answer, and if you don't know what to answer then don't, please.
Answer:
[tex]{{\underline{\textsf{\textbf{A. ∠AOB and ∠COB are supplementary to each other. }}}}}[/tex]
Step-by-step explanation:
As in the question given that, ∠AOB and ∠COB are linear pair and being theses angles are supplements it will form 180°. Hence, option A is the correct ✔️
∠AOB and ∠COB forms a linear pair
∠AOB and ∠COB are supplementary to each other
Given :
In the diagram, ∠AOB and ∠COB form a linear pair.
∠AOB and ∠COB forms a straight line . the sum of angles in a straight line is 180 degrees.
When the sum of angles is equal to 180 degree then they are called as supplementary angles.
∠AOB and ∠COB form a linear pair.
[tex]<AOB +<COB =180[/tex]
the sum of both the angles are equal to 180 degrees .
So, ∠AOB and ∠COB are supplementary to each other.

4 consecutive integers have a sum of 22. What is the least of the 4 integers?
Answer:
The least of the four integers is 4.
Step-by-step explanation:
Let x be the first integer.
x + (x + 1) + (x +2) + (x + 3) = 22
4x + 6 = 22
4x = 16
x = 4
4 + 5 + 6 + 7 = 22

Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek. If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?
Answer:
Eric's father works for 5 hours in the afternoon
Step-by-step explanation:
Eric's father works two part time jobs, one in the morning and one in the afternoon, and works a total of 40 hours each 5-day workweek.
Step 1
The number of hours he works each days is calculated as:
40 hours÷ 5days
= 8 hours per day.
Hence, he works 8 hours per day.
Step 2
We are told in the question that:
If his schedule is the same each day, and he works 3 hours each morning, how many hours does Eric's father work each afternoon?
The total number of hours in works in a day = Number of hours worked in the morning + Number of hours worked in the afternoon
Hence:
8 hours = 3 hours + x
x = 8 hours - 3 hours
x = 5 hours
Therefore, Eric's father works for 5 hours in the afternoon

The office manager of a small office ordered 180 packs of printer paper. Based on average daily use,
she knows that the paper will last about 40 days. How many packs of printer paper should the manager
expect to have after 35 days?
Answer:
22.5 packs of printer paper
Step-by-step explanation:
180/40 = 4.5
at a use of 4.5 per day over a period of 35 days, you have used 157.5
180-157.5 = 22.5
The number of packs of printer paper left after 35 days is given by the equation A = 27.5 packs of printing paper
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of packs of printer paper left after 35 days be A
Now , the equation will be
The total number of paper packs = 180 packs
The total number of days for the 180 packs of paper = 40 days
So , the number of packs of paper for 1 day = total number of paper packs / total number of days for the 180 packs of paper
Substituting the values in the equation , we get
The number of packs of paper for 1 day = 180 / 40
The number of packs of paper for 1 day = 4.5 paper packs a day
Now , the number of packs of paper for 35 days = 35 x number of packs of paper for 1 day
Substituting the values in the equation , we get
The number of packs of paper for 35 days = 35 x 4.5
The number of packs of paper for 35 days = 157.5 packs of paper
So , the number of packs of printer paper left after 35 days = total number of paper packs - number of packs of paper for 35 days
Substituting the values in the equation , we get
The number of packs of printer paper left after 35 days A = 180 - 157.5
The number of packs of printer paper left after 35 days A = 22.5 packs
Therefore , the value of A is 22.5 packs of paper
Hence , the number of packs of paper remaining is 22.5 packs
