Answers
The correct answer is OD. 8x + 1.
To divide 8x³ + x² - 32x - 4 by x² - 4, we can use polynomial long division.
The dividend is 8x³ + x² - 32x - 4, and the divisor is x² - 4.
We start by dividing the highest degree term, which is 8x³, by x². This gives us 8x.
Next, we multiply the divisor x² - 4 by the quotient 8x. The result is 8x³ - 32x.
Subtracting 8x³ - 32x from the dividend, we get x² - 32x.
Now, we divide x² - 32x by x² - 4. This gives us 1.
Multiplying the divisor x² - 4 by the quotient 1, we get x² - 4.
Subtracting x² - 4 from the remaining dividend, which is -32x, we get -32x + 4.
Since we can no longer divide, the final result is the quotient we obtained: 8x + 1.
Therefore, the correct answer is:
OD. 8x + 1.

Step-by-step explanation:
because they are parallel they have the same measure
The measure of angle 3 is equal to 114° when angle 7 is 114° by the corresponding angle property.
What are correspondence angles?The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
According to the definition of corresponding angles, when two parallel lines cross the third one, the angles that are in the same relative position at each intersection are referred to as being corresponding angles to one another.
In the image, it is given that angle 7 is 114 degrees. As in the image, the two parallel lines a and b are cut by the transversal line. The given angle 7 is 114°.
From the correspondence angle property, the two angles on the same side of the transversal line will be equal to each other. The angle 3 will be calculated as:-
∠7 = ∠3
114 = ∠3
Therefore, angle 3 will be 114°.

The correct value of \(x_a\) is infeasible.\(x_b, x_c, and x_e\)are feasible and in the interior of each constraint.\(x_d\)is infeasible due to violating the first constraint.
To determine whether each point is feasible or infeasible and whether it is interior or on the boundary of each constraint, we need to evaluate the points based on the given constraints.
The constraints are:
\(1 - x1^2 - x2^2\) ≥ 0
2 - x1 - x2 ≥ 0
3 - x2 ≥ 0
Let's evaluate each point:
a) \(x_a\) = (2/1, 2/1)T
Substituting the values into the constraints:
1\(- (2/1)^2 - (2/1)^2\) = 1 - 4 - 4 = -7 (not ≥ 0)
2 - 2/1 - 2/1 = 0 (≥ 0)
3 - 2/1 ≥ 0
Point\(x_a\) violates the first constraint, so it is infeasible.
b)\(x_b\)= (1, 0)T
Substituting the values into the constraints:
\(1 - 1^2 - 0^2\) = 0 (≥ 0)
2 - 1 - 0 = 1 (≥ 0)
3 - 0 ≥ 0
Point x_b satisfies all the constraints and is in the feasible region.
c) x_c = (-1, 0)T
Substituting the values into the constraints:
1 - (-1)^2 - 0^2 = 0 (≥ 0)
2 - (-1) - 0 = 3 (≥ 0)
3 - 0 ≥ 0
Point x_c satisfies all the constraints and is in the feasible region.
d) x_d = (-2/1, 0)T
Substituting the values into the constraints:
1 - (-2/1)^2 - 0^2 = 1 - 4 - 0 = -3 (not ≥ 0)
2 - (-2/1) - 0 = 1 (≥ 0)
3 - 0 ≥ 0
Point x_d violates the first constraint, so it is infeasible.
e) x_e = (2/√5, 1/√5)T
Substituting the values into the constraints:
1 - \((2/\sqrt{5} )^2 - (1/\sqrt{5} )^2 = 1 - 4/5 - 1/5\) = 0 (≥ 0)
2 - 2/√5 - 1/√5 = 0 (≥ 0)
3 - 1/√5 ≥ 0
Point x_e satisfies all the constraints and is in the feasible region.
To summarize:
\(x_a\) is infeasible.
\(x_b, x_c, and x_e\)are feasible and in the interior of each constraint.
\(x_d\)is infeasible due to violating the first constraint.

the point between p and k that is four times as far from p as it is k
Answers
Equations
Let's call
x = distance of the required point to the point P
The distance from P to K is 5 - (-2) = 7. This means the distance from the required point to K is (7 - x).
Our point is located 4 times as far from P than from K, thus:
4(7 - x) = x
Operating:
28 - 4x = x
Adding 4x:
28 = 5x
Dividing by 5:
x = 28/5 = 5.6
The required point is located at -2 + 5.6 = 3.6
Checking the distances:
3.6 - (-2) = 5.6
7 - 5.6 = 1.4
It can be verified that 5.6 is four times 1.4, thus
x = 5.6

Answers
535xy
Answer:
x= -8y / 5 +107
y = 535 - 5x / 8
Step-by-step explanation:
5x+8y=535
Subtract 8y from both sides.
5x=535−8y
Divide both sides by 5.
5x / 5 = 535 - 8y / 5
Dividing by 5 undoes the multiplication by 5.
x= 535−8y / 5
Divide 535−8y by 5.
x= -8y / 5 +107
5x+8y=535
Subtract 5x from both sides.
8y=535−5x
Divide both sides by 8
8y / 8 = 535 - 5x / 8
Dividing by 8 undoes the multiplication by 8.
y = 535 - 5x / 8

Answers
OLAP is used for the analysis of accumulated data, and it requires a data warehouse.
while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing. The analysis of accumulated data is known as Online Analytical Processing (OLAP), and it involves a data warehouse. OLAP is a business intelligence tool used for multi-dimensional analysis of large data sets, while a data warehouse is a central repository that stores historical and current data from multiple sources in a structured manner. OLAP allows users to perform complex queries on large data sets, analyze trends, and make informed business decisions. It is often used in data mining and decision support systems. OLAP tools can be used to slice and dice data, drill down to more detailed data, and roll up to higher levels of summary data. OLAP is primarily used for analytical purposes and is not designed for transaction processing. On the other hand, a data warehouse is designed to support OLAP and is used for storing large amounts of historical data that can be queried and analyzed. Data is extracted from various sources, transformed, and loaded into the data warehouse in a structured format, enabling efficient querying and analysis. OLTP (Online Transaction Processing), on the other hand, is a type of transaction processing that is designed for processing real-time transactions in databases. It is used for day-to-day operations such as order processing, inventory management, and customer management. OLTP is optimized for processing large volumes of transactions in real-time, and is not suitable for analytical purposes.

A consumer report revealed the following information about three tubes of toothpaste. A tube of Bright is 60% more expensive than a tube of Fresh and has 25% less volume than Glow. A tube of Glow is 25% less expensive than a tube of Bright and has 100/3 more volume than Fresh. Fresh costs 1. 00$ per unit of volume. What is the number of cents per unit of volume of Glow?
Answers
Glow costs 16/27 dollars, which is equal to 59.3 cents per volume unit.
Let's start by assigning variables to the unknown prices and volumes of the toothpastes. Let x be the price per unit volume of Fresh, y be the price per unit volume of Glow, and z be the price per unit volume of Bright. Let v1 be the volume of Fresh, v2 be the volume of Glow, and v3 be the volume of Bright. From the information given in the problem, we can set up the following equations:
z = 1.6y (a tube of Bright is 60% more expensive than a tube of Fresh)
v3 = 0.75v2 (a tube of Bright has 25% less volume than Glow)
y = 0.75z (a tube of Glow is 25% less expensive than a tube of Bright)
v2 = v1 + 100/3 (a tube of Glow has 100/3 more volume than Fresh)
We can substitute the first equation into the second equation to eliminate z:
v3 = 0.75v2
(substitute v2 = 0.75z and v1 = 1)
0.75v2 = 0.75(0.75z + 100/3)
0.75v2 = 0.5625z + 25
(substitute z = 1.6y and v2 = v1 + 100/3)
0.75(v1 + 100/3) = 0.5625(1.6y) + 25
0.75v1 + 25/3 = 0.9y + 25
0.75v1 = 0.9y + 50/3
We can substitute the third equation into the fourth equation to eliminate y:
v2 = v1 + 100/3
(substitute y = 0.75z)
0.75z = 0.75(0.75y) + 100/3
z = y + 16/9
(substitute z = 1.6y)
1.6y = y + 16/9
y = 16/27
Therefore, the price per unit volume of Glow is 16/27 dollars, or 59.3 cents per unit of volume.
