Where is the vertex of the quadratic y = (x -7)2 + 9
Final answer:
The vertex of the quadratic function y = (x -7)² + 9 is at the point (7, 9).
Explanation:
Vertex of a quadratic function is the highest or lowest point on the graph of the function. In this case, the quadratic function is in the form y = (x -7)² + 9.
To find the vertex, we notice that the function is in the form y = (x - h)² + k, where (h, k) represents the vertex. Therefore, the vertex of the given quadratic function is at (7, 9).

Step-by-step explanation:
Make a comparison between the government’s roles in a capitalist economic system versus a socialist or communist economic system.
A capitalist economic system is built on the respect of private property and competition. Hard work and free enterprise benefit citizens more than the government can. For the most part, government intervention is reduced. However, the government does provide security and some basic services, like infrastructure, to its citizens.
Socialist and communist systems endure more government control. Citizens of these economies have a limited amount of freedom by law. The government controls the market place and the production of most goods and services.

Given: KLMN is a parallelogram, KA − angle bisector of ∠K LA − angle bisector of ∠L Prove: m∠KAL = 90°
Final answer:
This answer explains how to prove that angle KAL is 90 degrees in a parallelogram using angle bisectors.
Explanation:
To prove: m∠KAL = 90°
Given: KLMN is a parallelogram, KA - angle bisector of ∠K, LA - angle bisector of ∠L.
Proof:
Since KA and LA are angle bisectors in parallelogram KLMN, m∠K = m∠L.In a parallelogram, consecutive angles are supplementary, so m∠K + m∠L = 180°.Substitute m∠K for m∠L in the above equation: m∠K + m∠K = 180°, which simplifies to 2m∠K = 180°, giving m∠K = 90°.Proved that the measure of angle KAL is 90 degrees, which means that angle KAL is a right angle.
To prove that [tex]\( m\angle KAL = 90^\circ \)[/tex], we need to use the properties of angle bisectors and parallelograms.
Step 1: Identify the properties of a parallelogram.
In a parallelogram, opposite sides are equal in length, and opposite angles are equal. Also, adjacent angles are supplementary, meaning they add up to 180 degrees.
Step 2: Apply the properties to parallelogram KLMN.
Since KLMN is a parallelogram, we have:
[tex]\[ m\angle K + m\angle L = 180^\circ \][/tex]
[tex]\[ m\angle K = m\angle M \][/tex]
[tex]\[ m\angle L = m\angle N \][/tex]
Step 3: Use the properties of angle bisectors.
An angle bisector divides an angle into two equal parts. Therefore, we have:
[tex]\[ m\angle KAK = m\angle KAA \][/tex]
[tex]\[ m\angle LAL = m\angle LAA \][/tex]
Step 4: Express the angles in terms of the bisected angles.
Since KA is the angle bisector of [tex]\( \angle K \)[/tex], we can express [tex]\( m\angle KAK \)[/tex]and [tex]\( m\angle KAA \)[/tex] as half of [tex]\( m\angle K \)[/tex]:
[tex]\[ m\angle KAK = m\angle KAA = \frac{1}{2}m\angle K \][/tex]
Similarly, since LA is the angle bisector of [tex]\( \angle L \)[/tex], we can express [tex]\( m\angle LAL \)[/tex] and [tex]\( m\angle LAA \)[/tex] as half of [tex]\( m\angle L \)[/tex]:
[tex]\[ m\angle LAL = m\angle LAA = \frac{1}{2}m\angle L \][/tex]
Step 5: Use the supplementary angle relationship.
Since [tex]\( \angle K \)[/tex] and [tex]\( \angle L \)[/tex] are supplementary, we have:
[tex]\[ m\angle K + m\angle L = 180^\circ \][/tex]
Dividing both sides by 2, we get:
[tex]\[ \frac{1}{2}m\angle K + \frac{1}{2}m\angle L = 90^\circ \][/tex]
Step 6: Substitute the expressions for the bisected angles.
[tex]\[ m\angle KAK + m\angle LAL = 90^\circ \][/tex]
[tex]\[ \frac{1}{2}m\angle K + \frac{1}{2}m\angle L = 90^\circ \][/tex]
Step 7: Recognize that [tex]\( m\angle KAL \)[/tex] is the sum of [tex]\( m\angle KAK \)[/tex]and[tex]\( m\angle LAL \)[/tex].
[tex]\[ m\angle KAL = m\angle KAK + m\angle LAL \][/tex]
Step 8: Substitute the values from Step 6 into the equation from Step 7.
[tex]\[ m\angle KAL = \frac{1}{2}m\angle K + \frac{1}{2}m\angle L \][/tex]
[tex]\[ m\angle KAL = 90^\circ \][/tex]
How many sequences of length 5 can be made when each component of the sequence can take 3 different values?
4j-2/2=4j+5
4j minus 2 divided by 2 equals 4j plus 5 ?
The solution to the equation (4j - 2) / 2 = 4j + 5 is j = -3. The equation was simplified by eliminating fractions and isolating the variable j through algebraic steps.
To solve the equation (4j - 2) / 2 = 4j + 5 for the variable j, you can follow these steps:
1. First, simplify both sides of the equation:
(4j - 2) / 2 = 4j + 5
2. Multiply both sides of the equation by 2 to eliminate the fraction:
4j - 2 = 2 * (4j + 5)
3. Distribute the 2 on the right side:
4j - 2 = 8j + 10
4. Move the variable terms to one side of the equation and the constants to the other side. You can do this by subtracting 8j from both sides:
4j - 8j - 2 = 10
5. Combine like terms:
-4j - 2 = 10
6. Add 2 to both sides to isolate the variable term:
-4j = 10 + 2
-4j = 12
7. Finally, divide both sides by -4 to solve for j:
j = 12 / -4
j = -3
So, the solution to the equation is j = -3.

Find the equation of the plane in xyzxyz-space through the point p=(5,5,3)p=(5,5,3) and perpendicular to the vector n=(1,2,5)
The equation of the plane in xyz-space that passes through the point p=(5,5,3) and is perpendicular to the vector n=(1,2,5) is x + 2y + 5z = 30.
Explanation:In mathematics, the equation of the plane can be found using the plane equation Ax + By + Cz = D. Given that the plane goes through point p=(5,5,3) and is perpendicular to vector n=(1,2,5). The vector n actually gives us the coefficients A, B, and C. Meaning A=1, B=2, and C=5. We get D by substituting the given point into the equation (Ax + By + Cz = D) as follows D = Ax + By + Cz = (1*5) + (2*5) + (5*3) = 5 + 10 + 15 = 30. Thus, the equation of the plane is x + 2y + 5z = 30.

Faelyn grouped the terms and factored the GCF out of the groups of the polynomial 6x4 – 8x2 + 3x2 + 4. Her work is shown.
Step 1: (6x4 – 8x2) + (3x2 + 4)
Step 2: 2x2(3x2 – 4) + 1(3x2 + 4)
Faelyn noticed that she does not have a common factor. Which accurately describes what Faelyn should do next?
Faelyn should realize that her work shows that the polynomial is prime.
Faelyn should go back and regroup the terms in Step 1 as (6x4 + 3x2) – (8x2 + 4).
In Step 2, Faelyn should factor only 2x out of the first expression.
Falyn should factor out a negative from one of the groups so the binomials will be the same.
Answer:
Faelyn should realize that her work shows that the polynomial is prime.
Explanation:
The only difference between her factors in Step 2 is that the 4 in the first group is negative, while the 4 in the second group is positive.
Rearranging the polynomial to factor it will not change the end result.
Factoring out a negative will make not only one, but both terms, in one of the binomials the opposite sign; this will not make the factors the same.
Factoring only 2x out of the first group will result in having (3x³+4x); this is not the same either.
She should realize that when this happens, her polynomial is prime.
The precision of what Faelyn should do is that Faelyn should realize that her work shows that the polynomial is prime. Hence, the option A is the correct option.

Juno deposited $750 in a savings account that earns 4% interest compounded annually. If she does not deposit or withdraw any more money, how much money will there be in the account after 13 years? Round your answer to the nearest dollar. A. $1249 B. $1360 C. $1427 D. $1140
Answer:
A. $1249.
Step-by-step explanation:
We have been given that Juno deposited $750 in a savings account that earns 4% interest compounded annually. We are asked to find the amount of money in the account after 13 years.
To solve our given problem, we will use compound interest formula. [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Amount after t years,
P = Principal amount,
r = Interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
Let us convert our given interest rate in decimal form.
[tex]4\%=\frac{4}{100}=0.04[/tex]
Upon substituting our given values in compound interest formula we will get,
[tex]A=\$750(1+\frac{0.04}{1})^{1\cdot 13}[/tex]
[tex]A=\$750(1+0.04)^{13}[/tex]
[tex]A=\$750(1.04)^{13}[/tex]
[tex]A=\$750\times 1.665073507310388[/tex]
[tex]A=\$1248.805130482791\approx \$1249[/tex]
Therefore, there will be $1249 in Juno's account after 13 years and option A is the correct choice.

Assuming boys and girls are equally likely, find the probability of a couple having a baby boyboy when their sixthsixth child is born, given that the first fivefive children were all boysall boys.
Answer:
50% probability of a couple having a baby boyboy when their sixth child is born, given that the first five were all boys.
Step-by-step explanation:
For each child, there are only two possible outcomes. Either it is a boy, or it is a girl. The probability of a child being a boy or a girl is independent of the other children. So we use the binomial probability distribution to solve this question.
The conditional probability formula is also used.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
Find the probability of a couple having a baby boyboy when their sixth child is born, given that the first five children were all boys.
Event A: First five children being boys.
Event B: Sixth children being a boy.
P(A):
First five children being boys.
P(X = 5) when n = 5.
Equally likely to be boy or girl, so p = 0.5.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(A) = P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125[/tex]
Intersection:
Intersection between the first five children being boys and the sixth also being a boy, so [tex]P(X = 6)[/tex] when n = 6.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(A \cap B) = P(X = 6) = C_{6,6}.(0.5)^{6}.(0.5)^{0} = 0.015625[/tex]
Probability:
[tex]P(B|A) = \frac{0.015625}{0.03125} = 0.5[/tex]
50% probability of a couple having a baby boyboy when their sixth child is born, given that the first five were all boys.

what are two functions, f(x) and g(x), that would result in a rational function?
Find the banker's interest to the nearest cent. Principal: $2,500; Rate: 9%; Time: 180 days: Interest: ? (based on a 365 day year).
Final answer:
The banker's interest rounded to the nearest cent is approximately $110.60.
Explanation:
To calculate the banker's interest on a principal of $2,500 at a rate of 9% for 180 days, you would apply the formula for simple interest:
Interest = Principal × rate × time
Since time needs to be expressed in years and the rate as a decimal, convert 180 days into a fraction of a year by dividing by 365:
Time (in years) = 180 / 365 ≈ 0.4932
Convert the rate to a decimal:
Rate (as a decimal) = 9% = 0.09
Now calculate the interest:
Interest = $2,500 × 0.09 × 0.4932 ≈ $110.595
Thus, the banker's interest rounded to the nearest cent is approximately $110.60.
