Polynomial Remainder Theorem
The polynomial remainder theorem establishes that the remainder of the division of a polynomial f(x) by (x-k) is equal to f(k), that is, substituting x for k.
We are given the polynomial:
[tex]f(x)= x^4+x^3-x^2+x-1[/tex]
And it's required to know if (x+1) and/or (x-1) are factors of the polynomial.
We apply the theorem for both cases.
For (x+1), we substitute x=-1 into the polynomial:
[tex]f(-1)= (-1)^4+(-1)^3-(-1)^2+(-1)-1[/tex]
[tex]f(-1)= 1-1-1-1-1=-3[/tex]
Since the remainder is not zero, x+1 is not a factor of the given polynomial.
For (x-1), we substitute x=1 into the polynomial:
[tex]f(-1)= (1)^4+(1)^3-(1)^2+(1)-1[/tex]
[tex]f(-1)= 1+1-1+1-1=1[/tex]
Since the remainder is not zero, x-1 is not a factor of the given polynomial.

If linda completed 20% of her science project on Monday, what percentage of her project is left to complete?
Answer:
80% because if she finished her project it would be 100%, but if we subtract 20% from 100, it would be 80% so she has 80% left to complete

Solve for the unknown length.
Answer:
37.5 units
Step-by-step explanation:
I assume that there is condition: BC║DE . If so, then ΔABC ~ ΔADE ⇒ that corresponding sides are proportional.
[tex]\frac{BC}{DE}[/tex] = [tex]\frac{AC}{AE}[/tex]
AC = 30 + 20 = 50
[tex]\frac{x}{15}[/tex] = [tex]\frac{50}{20}[/tex] ⇒ x = [tex]\frac{15*50}{20}[/tex] = 37.5 units

Molly estimated the her car insurance was going to be $250 each month. It was actually going to be $230 each month. What is the percent error? *
Answer:
8.69%.
Step-by-step explanation:
Estimated value = $250
Actual value = $230
We need to find the percent error. It can be calculated as follows :
[tex]\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%[/tex]
So, the percent error is 8.69%.

Which of the following points lies on the line 3y=2x-1?
A= (2,6)
B= (1,2)
C= (2,1)
D= (-2,1)
E= (2,-6)
Answer:
C
Step-by-step explanation:
I just plugged it in and checked tbh
The point C = ( 2, 1 ) lies on the line 3y = 2x - 1.
What is an equation of a line?The standard form of the equation of a line is given as:
ax + by + c = 0.
Here a, and b, are the coefficients, x, and y are the variables, and c is the constant term.
We have,
Equation of a line:
3y = 2x - 1
We need to check which point lies on the line.
A = ( 2, 6 )
3 x 6 = 2 x 2 - 1
18 = 4 - 1
18 ≠ 3
B = ( 1, 2 )
3 x 2 = 2 x 1 - 1
6 = 2 - 1
6 ≠ 1
C = ( 2, 1 )
3 x 1 = 2 x 2 - 1
3 = 4 - 1
3 = 3
D = ( -2, 1 )
3 x 1 = 2 x (-2) - 1
3 = -4 - 1
3 ≠ -5
E = ( 2, -6 )
3 x (-6) = 2 x 2 - 1
-18 = 4 - 1
-18 ≠ 3
Thus the point C = ( 2, 1 ) lies on the line 3y = 2x - 1.

The initial value of f(x) is 0.
The range of values for f(x) is 0 ≤ f(x) ≤ 6.
*Hint: You can use a table to do this one and plug in -4, -3, -2, and -1 in for x in the rule for the function of f(x), and -4 is your initial x-value. The answer from the first line is the same answer for the other blank.

Choose the correct value for the linear correlation between latitude and August precipitation from: (i) r= -1, (ii) r=-0.700, (iii) r=-0.161 or (iv) r=-0.538
Answer:
hello your question is incomplete attached below is the missing part of the question
answer : r = - 0.161 ( iii )
Step-by-step explanation:
The correct value for the linear correlation between latitude and August precipitation is ; r = - 0.161 and this is because the data points are showing a less negative correlation

Find two consecutive even integers such that the sum of the numbers is ten more than the larger number. (Must solve algebraically to receive full credit.)
Answer:
10 and 12
Step-by-step explanation:
Let the smallest number = 2x
Then the larger number is 2x + 2
2x + 2x + 2 = 2x + 2 + 10 Subtract 2x + 2 from both sides
2x = 10 Divide by 2
x = 5
The smaller number is 2x = 2 * 5 = 10
The larger number is 2x + 2 = 12

Write an equation in point-slope form for the line with a slope of 1/4 that passes through the point (-1, -8)
Answer:
y = 1/4 x - 31/4
Step-by-step explanation:
Slope (m) = 1/4
Point A (-1, -8)
y = mx + b
-8 = 1/4 (-1) + b
-8 + 1/4 = b
b = -32/4 + 1/4
b = -31/4
y = mx + b <-- this is a linear equation, continuing line, so there are infinite values for x and y. Therefore we don't have to plug the values of x and y in
y = 1/4 x + - 31/4
y = 1/4 x - 31/4
For f(x) = -5x +9, find f'(15)
Kevin has a rectangular
swimming pools that is 12
feet by 16 feet. He wants
to put a rope diagonally
across the pool. How long
does the rope need to
be?
Answer:
20 feet long
Step-by-step explanation:
To solve this you need to use the Pythagorean theorum, [tex]a^2+b^2=c^2[/tex], where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.
So, the equation is
[tex]12^2+16^2=c^2[/tex]
Which is then
[tex]144+256=c^2[/tex]
[tex]c^2=400[/tex]
And the possible values of c are 20 and -20.
From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.
Answer:
20 feet
Step-by-step explanation:
Use Pythagoras's theorem.
[tex]A^{2}+B^{2} =C^{2} \\12^{2} +16^{2}= C^{2} \\400 = C^{2} \\\sqrt{400}= \sqrt{C^{2}\\\\[/tex]
20 = C
