The product of the polynomials is 4x^(2)-28x+49, which is a single polynomial in standard form.
What is polynomial?A polynomial is an expression consisting of variables, constants and coefficients, in which the exponents of the variables are either whole numbers or zero. It can be written in the form of a summation, where each term is the product of a coefficient and a variable raised to a power.
To multiply the polynomials using a special product formula, we can use the formula for squaring a binomial, which is (a-b)^(2)=a^(2)-2ab+b^(2). In this case, a=2x and b=7.
So, we can plug these values into the formula and simplify:
(2x-7)^(2) = (2x)^(2)-2(2x)(7)+(7)^(2)
= 4x^(2)-28x+49

and
3.73205,−0.24,0
and
4.24,0
are not the correct answers so if that's what you get, please do not respond with those answers.
The vertex of the function is (2 , -5), the axis of symmetry is x = 2, and the intercepts are (2 + √(5) , 0), (2 - √(5) , 0), and (0 , -1).
To find the vertex, axis of symmetry, and intercepts of the function f(x) = x² - 4x - 1, we can use the following formulas:
Vertex: (-b/2a, f(-b/2a))
Axis of symmetry: x = -b/2a
Intercepts:
x-intercept: set f(x) = 0 and solve for x
y-intercept: set x = 0 and solve for y
Using these formulas, we can find the vertex, axis of symmetry, and intercepts of the function:
f(x) = x² - 4x - 1
a = 1, b = -4, c = -1
Vertex: (-b/2a , f(-b/2a)) = (-(-4)/(2)(1) , f(-(-4)/(2)(1))) = (2 , f(2)) = (2 , (2)² - 4(2) - 1) = (2 , -5)
Axis of symmetry: x = -b/2a = -(-4)/(2)(1) = 2
Intercepts:
x-intercept: 0 = x² - 4x - 1
use the quadratic formula to solve for x: x = (-b ± √(b² - 4ac))/(2a) = (-(-4) ± √((-4)² - 4(1)(-1)))/(2(1)) = (4 ± √(20))/2 = (4 ± 2√(5))/2 = 2 ± √(5)
so the x-intercepts are (2 + √(5) , 0) and (2 - √(5) , 0)
y-intercept: f(0) = (0)² - 4(0) - 1 = -1; so the y-intercept is (0 , -1)

I need help determining the exponential function in the form of y=a(m) x
HELP PLS ☹️
Answer:
An exponential function in the form of y = a(m) x is of the form:
y = a * m^x
where "a" is a constant, "m" is a positive constant (the base of the exponential), and "x" is the independent variable.
To determine the exponential function in this form, you need to have some information about the function, such as its value at a particular point or its rate of growth.
Here are the general steps to determine the exponential function in the form of y = a(m) x:
Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.
Determine the value of "m" by solving for it using the given information.
For example, let's say you are given that the function passes through the point (2, 8) and has a growth rate of 3. To determine the exponential function in the form of y = a(m) x, you would follow these steps:
Plug in the values of x and y into the equation:
8 = a * m^2
Solve for "a" by isolating it on one side of the equation:
a = 8 / m^2
Use the given growth rate of 3 to find the value of "m":
m = 1 + r = 1 + 0.03 = 1.03
Plug in the value of "m" and the value of "a" you found in step 2 into the equation:
y = (8 / 1.03^2) * 1.03^x
Simplifying this equation gives:
y = 7.514 * 1.03^x
So the exponential function in the form of y = a(m) x that passes through the point (2, 8) and has a growth rate of 3 is y = 7.514 * 1.03^x.
Step-by-step explanation:
here is a more detailed explanation of the steps involved in determining an exponential function in the form of y = a(m) x:
Determine the value of "a" by plugging in the known value of "y" and "x" into the equation.
In the equation y = a(m) x, "a" is a constant that represents the value of y when x is equal to 0. So to find the value of "a", we need to know the value of y for a specific value of x, other than 0.
Three variants of the gene encoding for the beta-goblin component of hemoglobin occur in the human population of the Kassena-Nankana district of Ghana, West Africa. The most frequent allele, A, occurs at a frequency of 0.83. The other two variants, S (sickle cell) and C, occur at frequency 0.04 and 0.13. Each individual has two alleles, determining the genotype of the beta-globin gene. Assume that the allele occur independently on one another.
a. What is the probability that a randomly sampled individual has two copies of the C allele?
b. What is the probability that a randomly sampled individual is a homozygote (two copies of the same allele)?
c. What is the probability that a randomly sampled individual is AS (one copy of A allele and one copy of S allele)?
d. What is the probability that a randomly sampled individual is AS or AC?
a. The probability that a randomly sampled individual has two copies of the C allele is 0.0169.
b. The probability that a randomly sampled individuTherefore, the answers are:
al is a homozygote is 0.7074.
c. The probability that a randomly sampled individual is AS is 0.0332.
d. The probability that a randomly sampled individual is AS or AC is 0.1411.
The probability of an individual having two copies of the C allele can be calculated using the formula for the probability of independent events: P(CC) = P(C) x P(C) = 0.13 x 0.13 = 0.0169.
The probability of an individual being a homozygote can be calculated by adding the probabilities of having two copies of each allele: P(AA) + P(SS) + P(CC) = (0.83 x 0.83) + (0.04 x 0.04) + (0.13 x 0.13) = 0.6889 + 0.0016 + 0.0169 = 0.7074.
The probability of an individual being AS can be calculated using the formula for the probability of independent events: P(AS) = P(A) x P(S) = 0.83 x 0.04 = 0.0332.
The probability of an individual being AS or AC can be calculated by adding the probabilities of each event: P(AS) + P(AC) = 0.0332 + (0.83 x 0.13) = 0.0332 + 0.1079 = 0.1411.

f (x) = -3x4 + 6x3 + 33x2 - 18x - 108.
The correct answer is a. f (x) = -3x4 + 6x3 + 33x2 - 18x - 108, since this is a polynomial of the lowest degree (4) that has zeros of -2 (multiplicity 2) and 3 (multiplicity 2), as well as f(0)=-108. To solve this problem, use the Factor Theorem to determine the factors of the polynomial. Since the zeros are -2 and 3, the polynomial must factor into (x+2)2 and (x-3)2. This gives us the polynomial: f (x) = -3(x+2)2(x-3)2 - 108. Finally, expand the polynomial to get the answer: f (x) = -3x4 + 6x3 + 33x2 - 18x - 108.

The following table gives the frequency distribution of waiting
times (in minutes) for these customers.
The mean waiting time is:
The mean waiting time for these customers is 18.33 minutes.
The mean waiting time can be calculated by multiplying each waiting time by its frequency, summing up these products, and then dividing by the total number of customers.
In mathematical terms, the mean waiting time is:
Mean = (x1 * f1 + x2 * f2 + ... + xn * fn) / (f1 + f2 + ... + fn)
Where x1, x2, ..., xn are the waiting times, and f1, f2, ..., fn are the corresponding frequencies.
Using the data from the table, we can plug in the values and calculate the mean waiting time:
Mean = (5 * 2 + 10 * 4 + 15 * 6 + 20 * 8 + 25 * 10) / (2 + 4 + 6 + 8 + 10)
Mean = (10 + 40 + 90 + 160 + 250) / 30
Mean = 550 / 30
Mean = 18.33 minutes

b. Image: (-1, -10)
c. Image: (-4/3, -10)
d. Image: (14/3, -10)
What is general transformations?
A transformation is a procedure that involves either changing an object's orientation to create an image or expanding or reducing its size to create a new one.
We'll use the given point (4, -10) as the input for each transformation, and apply the transformation to find the new location of the point.
a. f(x) = (x + 2) - 3
f(4) = (4 + 2) - 3 = 3
Therefore, the new location of the point under the transformation f(x) = (x + 2) - 3 is (3, -10).
b. f(x) = 2(x - 4) - 1
f(4) = 2(4 - 4) - 1 = -1
Therefore, the new location of the point under the transformation f(x) = 2(x - 4) - 1 is (-1, -10).
c. f(x) = -1/3x
f(4) = -1/3(4) = -4/3
Therefore, the new location of the point under the transformation f(x) = -1/3x is (-4/3, -10).
d. f(x) = (2/3)x + 2
f(4) = (2/3)(4) + 2 = 8/3 + 2 = 14/3
Therefore, the new location of the point under the transformation f(x) = (2/3)x + 2 is (14/3, -10).
In each case, the image of the point is the new location after applying the transformation.
a. Image: (3, -10)
b. Image: (-1, -10)
c. Image: (-4/3, -10)
d. Image: (14/3, -10)

nominal yield, 6.5%; compounded monthly
Question 10 answer options:
0.07%
6.70%
106.70%
0.54%
The effective interest rate for the specified account is 6.70%.
To find the effective interest rate, we can use the following formula:
Effective Interest Rate = (1 + Nominal Yield / Number of Compounding Periods) ^ Number of Compounding Periods - 1
In this case, the nominal yield is 6.5% and the number of compounding periods is 12 (since it is compounded monthly). Plugging these values into the formula, we get:
Effective Interest Rate = (1 + 0.065 / 12) ^ 12 - 1
Effective Interest Rate = (1.0054166666666667) ^ 12 - 1
Effective Interest Rate = 1.0670171619870418 - 1
Effective Interest Rate = 0.0670171619870418
Multiplying by 100 to convert to a percentage, we get:
Effective Interest Rate = 6.70%

A trapezoid is a 4-sided (square) shape in which some sides are parallels and others not. The midsection of a trapeze is the line that runs from the middle of one leg to the middle of the other. The midsection or Midsegment theorem of a trapezium states that if a line parallel to the two bases passes through the middle of one leg, it also passes through the middle of the other leg. Also, the length of the middle fragment is half the length of two bases. Now we see a trapezoid in the image above, the length of the midsegment = 25
One of the bases of the trapezium = 37
We need to calculate the value of the other base length P Using Midsigment or Midline Theorem, Midsigment = length of two bases/2
=> 25 = (37 + P)/2
=> 50 = 37 + P
=> P = 50 - 37
=> P = 13

Bear visits form a Poisson process of rate 1 visit per month.
Number of visits in a month = Poisson distribution with parameter λ = 1.
Let X be the number of visits in a month.
And Y be the total number of bears in the month.
Probability of X and Y is equal to ,
P(X = i, Y = j), for i = 0, 1, 2, 3 and j = i, 2i, or 3i.
Law of total probability for P(X = i, Y = j) for each i and j.
P(X = i, Y = i)
= P(X = i) × P(Y = i | X = i)
= e^(-λ) × λ^i / i! × 1/3^i
= e^(-1) × 1^i / i! × 1/3^i
= e^(-1) (1/ i!) × 1/3^i
Now,
P(X = i, Y = 2i)

For,
P(X = i, Y = 3i)
= P(X = i) × P(Y = 3i | X = i)
= e^(-λ) × λ^i / i! × (1/3)^i × 2

The complete factorization of the expression 144p² - 9q² is (12p + 3q)(12p − 3q). The correct answer is B.
To factor 144p² - 9q², we can use the difference of squares formula, which states that:
a² - b² = (a + b)(a - b)
We can see that 144p² is a perfect square, as it is the square of 12p. Similarly, 9q² is a perfect square, as it is the square of 3q. So we can write:
144p² - 9q² = (12p)² - (3q)²
Now we can use the difference of squares formula to factor:
(12p)² - (3q)² = (12p + 3q)(12p - 3q)
Simplifying, we can also write this as:
144p² - 9q² = 3²(16p² - q²)
So, the factored form of 144p² - 9q² is:

what two situations involving rational exponents or radicals will never result in a negative real soltution
Answer:
There are two situations involving rational exponents or radicals that will never result in a negative real solution:
Even-indexed roots: If we take the square root, fourth root, sixth root, etc. of a non-negative real number, the result will always be non-negative. For example, the square root of 9 is 3, and the fourth root of 16 is 2, both of which are non-negative. This is because even-indexed roots always produce a non-negative result, regardless of the sign of the original number.
Exponents with even denominators: If we raise a non-negative real number to an exponent with an even denominator, the result will always be non-negative. For example, (4^2/4) is equal to 4, which is non-negative. This is because any negative base raised to an even power results in a positive number, and any positive base raised to an even power also results in a positive number. Therefore, any exponent with an even denominator will always produce a non-negative result, regardless of the sign of the original number.

Let [tex]$a$[/tex] and [tex]$b$[/tex] be arbitrary elements in [tex]$R$[/tex].
[tex]$a+b = (a+b)^2 = a^2 + 2ab + b^2$[/tex]
[tex]$b+a = (b+a)^2 = b^2 + 2ab + a^2$[/tex]
Therefore, [tex]$a+b = b+a$[/tex]. Thus, R is a ring commutative.

3. 1 130 points) Solve the following system of linear equations by the Matrix Inversion method using A' = ad/ ) det(A) 2x + 6y + 2z = 8 6x + 6y + 32-3 2x + 3y+z=3
So, the solution to the system of equations is:
x = -26/7
y = -25/7
z = -37/7
Solving a system of linear equations by the Matrix Inversion method involves finding the inverse of the coefficient matrix, multiplying it by the constant matrix, and solving for the variables.
First, we need to write the system of equations in matrix form:
[ 2 6 2 ] [ x ] [ 8 ]
[ 6 6 3 ] [ y ] = [ -3 ]
[ 2 3 1 ] [ z ] [ 3 ]
Next, we need to find the inverse of the coefficient matrix:
A = [ 2 6 2 ]
[ 6 6 3 ]
[ 2 3 1 ]
The determinant of A is:
det(A) = 2(6-9) - 6(2-6) + 2(18-6) = -6 + 24 + 24 = 42
The adjoint of A is:
adj(A) = [ (6-3) (-2+6) (-18+6) ]
[ (-6+3) (2-4) (12-6) ]
[ (6-18) (-2+12) (2-18) ]
= [ 3 4 -12 ]
[ -3 -2 6 ]
[ -12 10 -16 ]
The inverse of A is:
A' = (1/det(A))adj(A) = (1/42)[ 3 4 -12 ]
[ -3 -2 6 ]
[ -12 10 -16 ]
= [ 1/14 2/21 -4/7 ]
[ -1/14 -1/21 2/7 ]
[ -4/7 5/21 -8/21 ]
Now, we can multiply the inverse of A by the constant matrix to find the solution:
[ x ] [ 1/14 2/21 -4/7 ] [ 8 ]
[ y ] = [ -1/14 -1/21 2/7 ] [ -3 ]
[ z ] [ -4/7 5/21 -8/21 ] [ 3 ]
= [ (8/14) + (16/21) + (-32/7) ]
[ (-8/14) + (-3/21) + (-6/7) ]
[ (-32/7) + (15/21) + (-24/21) ]
= [ -26/7 ]
[ -25/7 ]
[ -37/7 ]
So, the solution to the system of equations is:
x = -26/7
y = -25/7
z = -37/7

Translate the logarithmio statoment into an equivalent exponential statement. log_(4)(1)/(16)=-2
The logarithmic statement [tex]log_(4)(1)/(16)=-2[/tex] can be translated into the equivalent exponential statement [tex]4^(-2)=(1)/(16)[/tex].
The logarithmic statement [tex]log_(4)(1)/(16)=-2[/tex] can be translated into an equivalent exponential statement by using the definition of logarithms. The definition of logarithms states that if [tex]log_(b)(a)=c[/tex], then [tex]b^c=a.[/tex]
Using this definition, we can translate the logarithmic statement[tex]log_(4)(1)/(16)=-2[/tex] into an equivalent exponential statement by rearranging the terms.
The equivalent exponential statement would be[tex]4^(-2)=(1)/(16)[/tex]. This means that 4 raised to the power of -2 is equal to 1/16.
So, the logarithmic statement [tex]log_(4)(1)/(16)=-2[/tex]can be translated into the equivalent exponential statement[tex]4^(-2)=(1)/(16)[/tex].

Mrs Shepard rode her bike 5. 25 miles in 0. 7 hours how fast was she going in miles per hour
Mrs Sheperd was going 7.5 miles per hour
Let us assume that d represents the distance covered by Mrs Shepard, 't' represents the time required and 's' represents the speed of her bike.
Here, d = 5.25 miles
t = 0.7 hours
We know that the formula of speed is speed = distance/time
Using this formula we calculate the speed (s) of Mrs Shepard's bike.
speed = distance/time
⇒ s = d/t
⇒ s = 5.25/0.7
⇒s = 7.5 miles per hour
This means that the speed (s) of Mrs Shepard's bike was 7.5 miles per hour
