Filling in the blanks:
1. Opposite 2. C3. OppositeFactoring the polynomial:
x² + 11x - 26 = x² + 13x - 2x - 26 = x(x + 13) - 2(x + 13) = (x - 2)(x + 13)The leaning Tower of Pisa is 84.32 meters (m) long.
84.32 m
height
not to scale
In the 1900s, engineers restored the building so that angle y changed from 6.5° to
2.8°. To the nearest hundredth of a meter, how much did the restoration change the
height of the leaning Tower of Pisa?
Answer:
67.32m
Step-by-step explanation:
Given 1+2i as a zero of f(x) = x^4 - 2x^3 - 4x^2 + 18x - 45, find all other zeros and write the complete factorization. Please show work if you can.
Answer:
(x + 3)(x - 3)(x² - 2x + 5)Step-by-step explanation:
One of the zeros given:
1 + 2iSince it is a complex number, its conjugate is also a zero:
1 - 2iThe product of two factors are:
(x - (1 + 2i))(x - (1 - 2i)) = x² - x(1 + 2i + 1 - 2i) + (1 - 4i²) = x² - 2x + 5We need two more zeros. Let them be m and n, then we have:
(x - m)(x - n) = x² - (m +n)x + mnThe product of all factors:
(x² - 2x + 5)(x² - (m+n)x + mn) = x⁴ - 2x³ - 4x² + 18x - 45x⁴- (m+n+2)x³ + (mn+5)x² - (2mn+5m+5n)x + 5mn = x⁴- 2x³- 4x²+ 18x- 45Compare left and right sides and solve for m and n:
m + n + 2 = 2 ⇒ m + n = 0mn + 5 = -4 ⇒ mn = -92mn + 5(m + n) = -18 ⇒ mn = -9From the above equations we get:
m = -n-n² = -9 n = 3m = -3The other zero's are 3 and -3
All of the factors:
(x + 3)(x - 3)(x² - 2x + 5)Answer:
(x−3)(x+3)(x^2-2x+5)
Step-by-step explanation:
f(x) = x^4 - 2x^3 - 4x^2 + 18x - 45
To factor the expression, solve the equation where it equals to 0.
x^4 - 2x^3 - 4x^2 + 18x - 45 = 0
By Rational Root Theorem, all rational roots of a polynomial are in the form p/q where p divides the constant term −45 and q divides the leading coefficient 1. List all candidates p/q.
±45,±15,±9,±5,±3,±1
Find one such root by trying out all the integer values, starting from the smallest by absolute value. If no integer roots are found, try out fractions.
x=3
By Factor theorem, x−k is a factor of the polynomial for each root k. Divide x^4 - 2x^3 - 4x^2 + 18x - 45 by x−3 to get x^3 + x^2 - x + 15. To factor the result, solve the equation where it equals to 0.
x^3 + x^2 - x + 15 = 0
By Rational Root Theorem, all rational roots of a polynomial are in the form p/q where p divides the constant term 15 and q divides the leading coefficient 1. List all candidates p/q.
±15,±5,±3,±1
Find one such root by trying out all the integer values, starting from the smallest by absolute value. If no integer roots are found, try out fractions.
x=−3
By Factor theorem, x−k is a factor of the polynomial for each root k. Divide x^3 + x^2 - x + 15 by x+3 to get x^2 - 2x + 5. To factor the result, solve the equation where it equals to 0.
x^2−2x+5=0
All equations of the form ax^2 + bx + c=0 can be solved using the quadratic formula: −b±√b2-4ac/2a. Substitute 1 for a, −2 for b, and 5 for c in the quadratic formula.
x=-(-2)+√(-2)^2 - 4 x 1 x 5 / 2
Do the calculations.
x=2+√-16 / 2
Polynomial x^2−2x+5 is not factored since it does not have any rational roots.
x^2−2x+5
Rewrite the factored expression using the obtained roots.
(x−3)(x+3)(x^2-2x+5)

Answer:
5/10 + 3/10 = 8/10
5/10 - 3/10 = 2/10
Step-by-step explanation:
1/2 = 5/10
5/10 + 3/10 = 8/10
5/10 - 3/10 = 2/10
Answer: 1/2+3/10
= 5/10+3/10=8/10=0.8=80%

Answer:
9/16 inch
Step-by-step explanation:
A = 3/4 +1/16
B = 1/4
x = A - B
x = (3/4 +1/16) - (1/4) . . . an equation for the difference
x = (12/16 + 1/16) - 4/16 = (13 -4)/16
x = 9/16
The difference between A and B on the ruler is 9/16 inch.

What is the force exerted on an object
with a mass of 20 kg and an
acceleration of 6 m/s2?
Answer:
F = 120 N
Step-by-step explanation:
Given that,
The mass of the object, m = 20 kg
Acceleration of the object, a = 6 m/s²
We need to find the force exerted on an object. The force exerted on an object is given by :
[tex]F=ma\\\\F=20\ kg\times 6\ m/s^2\\\\F=120\ N[/tex]
So, the required force exerted on the object is 120 N.
Pizazz manufactures a 5.0 oz. energy drink of the same name. Because the cans are so small, consumers are concerned that they are not receiving the full 5 ounces in each can. A quality engineer at the company is charged with analyzing the filling process and ensuring accurate readings. On 15 different occasions over the past month, she has taken a sample of 6 energy drinks off the production line and recorded their weight. The sum of the sample means is 80.20 ounces and the sum of the sample ranges is 12.68 ounces (Hint: You are already given the sum. You just have to find the x-double bar and R-bar).
Determine the control limits of an x-bar and R-chart. What is your conclusion?
Answer:
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
LCL of R-chart = 0 * 0.84533 = 0
LCL of R-chart = 75.128
Step-by-step explanation:
Given data:
number of observations = 15
sample size ( m ) = 6
sum of sample mean = 80.20 ounces
sum of sample range ( R ) = 12.68 ounces
Determine the control limits of an x-bar and R-chart
for an R-chart
LCL of R-chart = D3 * R(bar) ---- ( 1 )
where : m = 6 , D3 = 0 , R = 12.68
R(bar) = 0.84533
back to equation 1
LCL of R-chart = 0 * 0.84533 = 0
for an X-chart
LCL of X-bar) = ( mean ) - (m x R-bar)
= 80.20 - ( 6 * 0.84533 )
= 75.128
The LCL of the R-chart starts from the origin ( i.e. zero value ) while the LCL of an X -chart did not start from the origin
