x²-10xy + 16y²-z² + 6yz
Answer:
(x - 8y + z)(x - 2y - z)
Step-by-step explanation:
Factorize :
x²-10xy + 16y²-z² + 6yz
Solution:
x²-10xy + 16y²-z² + 6yz
Firstly, make sure that all the terms are arranged in a well ordered manner:
x²-10xy + 16y²-z² + 6yz
Secondly, split the term (16y²) common to both equation:
(x²-10xy + 25y²) - 9y² -z² + 6yz
Thirdly, factorize both terms:
(x - 5y)² - 1(z² - 6yz + 9y²)
Factorizing the second term:
(x - 5y)² - (z - 3y)²
Using the difference of two squares, that is A² - B² = (A + B)(A - B):
(x - 5y)² - (z - 3y)² = [(x - 5y) + (z - 3y)][(x - 5y) - (z - 3y)]
= [x - 5y + z - 3y][x - 5y - z + 3y]
= (x - 8y + z)(x - 2y - z)
Write .125 as a fraction reduced to lowest terms.
Answer:
125 as a fraction is 1/8.
0.125 = 125/1000. We can reduce this to lowest terms by dividing the numerator and denominator by 125 to get the equivalent fraction 1/8.

A jean manufacturer makes three types of jeans, each of which goes through three manufacturing phases: cutting, sewing, and finishing. The number of minutes each type of product requires in each of the three phases is given below:
Jean Cutting Sewing Finishing
I 8 12 4
II 12 18 8
III 18 24 12
There are 5200 minutes of cutting time, 6000 minutes of sewing time, and 2200 minutes of finishing time each day. The company can sell all the jeans it makes and makes a profit of $4 on each Jean I, $4.50 on each Jean II, and 6 on each Jean III.
Required:
a. What number of jeans in each category should be made each day to maximize profits?
b. Formulate a linear programming problem that models the problem given above. Be sure to identify all variables used.
c. Analyze the solution.
Answer:
z ( max) = 2000 $
x₁ = 500 x₂ = 0 x₃ = 0
Step-by-step explanation:
cutting sewing finishing Profit $
Jean1 (x₁ ) 8 12 4 4
Jean2 (x₂ ) 12 18 8 4.5
Jean3 (x₃ ) 18 24 12 6
Time available 5200 6000 2200
b) Formulation of a linear programming problem:
Objective Function z
z = 4*x₁ + 4.5*x₂ + 6*x₃ to maximize
Constrains:
Constrain 1
Available cutting time 5200 minutes
8*x₁ + 12*x₂ + 18*x₃ ≤ 5200
Constrain 2:
Available sewing time 6000 minutes
12*x₁ + 18*x₂ + 24*x₃ ≤ 6000
Constrain 3:
Available finishing time 2200 minutes
4*x₁ + 8*x₂ + 12*x₃ ≤ 2200
General constraints:
x₁ ≥ 0 x₂ ≥ 0 x₃ ≥ 0 all integers
After 6 iterations the optimal solution is:
z ( max) = 2000 $
x₁ = 500 x₂ = 0 x₃ = 0
We can see in the model that times required to make jean 2 and jean 3
are much bigger than jean 1 and but the price of jean 2 is only 0.5 $ above the price of jean 1 and jean 3 is only 2 $.

An auto insurance company concludes that 30% of policyholders with only collision coverage will have a claim next year, 40% of policyholders with only comprehensive coverage will have a claim next year, and 50% of policyholders with both collision and comprehensive coverage will have a claim next year. Records show 60% of policyholders have collision coverage, 70% have comprehensive coverage, and all policyholders have at least one of these coverages. Calculate the percentage of policyholders expected to have an accident next year.
Answer:
40% of policyholders are expected to have an accident next year
Step-by-step explanation:
Given the data in the question;
P( collision coverage ) = 60% = 0.6
P( comprehensive coverage ) = 70% = 0.7
Now, we make use of the Law of addition of probability, so
P( collision coverage and comprehensive coverage ) = P( collision coverage ) + P( comprehensive coverage ) - P( collision coverage or comprehensive coverage )
P( collision coverage and comprehensive coverage ) = 0.6 + 0.7 - 1
P( collision coverage and comprehensive coverage ) = 0.3
Now,
P( comprehensive coverage only ) = P( comprehensive coverage ) - P( collision coverage and comprehensive coverage )
P( comprehensive coverage only ) = 0.7 - 0.3
P( comprehensive coverage only ) = 0.4
And
P( collision coverage only) = P( collision coverage ) - P( collision coverage and comprehensive coverage )
P( collision coverage only) = 0.6 - 0.3 = 0.3
Next we make use of the Law of total probability;
P( accident ) = [P( accident ║ collision coverage only) × P( collision coverage only)] + [P( accident ║ comprehensive coverage only) × P( comprehensive coverage only)] + [P( accident ║ collision coverage and comprehensive coverage only) × P( collision coverage and comprehensive coverage only)]
so we substitute in our values;
P( accident ) = [ 30% × 0.3 ] + [ 40% × 0.4 ] + [ 50% × 0.3 ]
P( accident ) = [ 0.3 × 0.3 ] + [ 0.4 × 0.4 ] + [ 0.5 × 0.3 ]
P( accident ) = 0.09 + 0.16 + 0.15
P( accident ) = 0.4 or 40%
Therefore, 40% of policyholders are expected to have an accident next year

Which function results after applying the sequence of transformations to
f(x) = x5?
• reflection over the x-axis
• vertically stretch by a factor of 2
• shift down 1 unit
Answer:
A. g(x) = -2x^5 - 1.
Step-by-step explanation:
Reflection over the x axis results in the function -x^5.
Vertical stretch of 2 gives -2x^5
Finally a shift down of 1 unit gives -2x^5 - 1
The function results after applying the sequence of transformations to
f(x) = x⁵ is,
⇒ g(x) = -2x⁵ - 1.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now,
After Reflection over the x axis results in the function is,
g (x) = - x⁵
And, After Vertical stretch of 2 gives,
g (x) = -2x⁵
Then, Finally a shift down of 1 unit gives,
g (x) = -2x⁵ - 1
Thus, The function results after applying the sequence of transformations to f(x) = x⁵ is,
⇒ g(x) = -2x⁵ - 1.

Interpret the 95% confidence interval for average BMI. What do the lower and upper bounds of the confidence interval tell us?
Answer:
(26.2252 ; 27.3748)
Step-by-step explanation:
The confidence interval is given by :
x ± Margin of error
The margin of error = Zcritical * (σ/√(n))
σ = 7.5 ; n = 654
Zcritical = Zα/2 = 1.96
The margin of error = 1.96 * (7.5/√654) = 0.5748
The confidence interval :
Upper boundary = 26.8 + 0.5748 = 27.3748
Lower boundary = 26.8 - 0.5748 = 26.2252
(26.2252 ; 27.3748)
We are 95% confident that the mean BMI of the entire population will fall in between (26.2252 ; 27.3748)

Benecio skis 748 yd in 3 min. At this rate, how many miles does Benecio ski in an
hour in miles?
Answer:
8.5 miles an hour.
Step-by-step explanation:
There are many ways to do this, but I am going to do it the way I think is the most simple.
First, divide 748 yards by 3 minutes to get the amount of yards per minute. 748 / 3 = 249.33333
Second, divide the previously gotten number (249.33333, [3's go on forever]) by the amount of yards in a mile (which is 1760 yards per mile). This turns into 249.33333 / 1760 = 0.1416666 (6's go on forever). This is miles per minute so you must make it per hour.
You then multiply that infinite number by the amount of minutes in an hour (60 minutes per hour). 0.14166666 * 60 = 8.5 miles per hour.

21. The average of 5 consecutive integers starting with m
as the first integer is n. What is the average of 9
consecutive integers that start with m+2?
A) m + 4
B) n + 6
C) n+ 4
D) m + 5
Answer:
n + 4
Step-by-step explanation:
Given
⅕(m + m + 1 + m + 2 + m + 3 + m + 4) = n
Required
⅑(m + 2 + m + 3 +.......+ m + 10)
We have:
⅕(m + m + 1 + m + 2 + m + 3 + m + 4) = n
Multiply both sides by 5
m + m + 1 + m + 2 + m + 3 + m + 4 = 5n
Collect like terms
m + m + m + m + m = 5n - 1 - 2 - 3 - 4
5m = 5n - 10
Divide both sides by 5
m = n - 2
So, we have:
⅑(m + 2 + m + 3 + m + 4 + m + 5 + m + 6 + m + 7 + m + 8 + m + 9 + m + 10)
Collect like terms
= ⅑(m+m+m+m+m+m+m+m+m+2+3+4+5+6+7+8+9+10)
= ⅑(9m + 54)
= m + 6
Substitute n - 2 for m
= n - 2 + 6
= n + 4

How many years (to two decimal places) will it take $15000 to grow to $17500 if it is invested at 8% compounded semi- annually?
Answer:
1.97 years
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 8/100
r = 0.08 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.08/2)] )
t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.04)] )
t = 1.965 years

need help with algebra question ‼️
Answer:
c
Step-by-step explanation:
There are three types of variations.
1. Direct
2. Inverse
3. Joint
There is positive proportionality is two variables are positively related to each other.
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable
the equation that represents inverse proportion :
where b = constant of proportionality
Joint variation occurs when the dependent variables value is determined by two or more values
For example, the volume of a cylinder is dependent on the value of the radius and height
