Express as a trinomial: (2x+3)(2x−4)
Answer:
is this the answer ur looking for
Step-by-step explanation:
Trinomial of (2x+3)(2x−4) will be represented as \(4x^2 -6x -12\)
What is a trinomial?Expressions with one term are called monomials, others with two terms are called binomials, and those with three parameters are called trinomials. An expression containing upwards of three segments is given a name based solely on that integer. Five-term polynomials, for instance, is a linear function comprising four terms.
A trinomial in modular arithmetic is a polynomial made up of three terms, typically monomials. An exponential function known as a trinomial comprises triple non-zero terms and much more only one element. For instance: \(x^2 -10y - 25\)
The Trinomial of (2x+3)(2x−4) is
= (2x+3)(2x− 4)
= \(2x*2x - 2x*4 +3*2x -4*3\\\)
= \(4x^2 -12x +6x -12\)
= \(4x^2 -6x -12\)
The polynomial that will be formed will be \(4x^2 -6x -12\).

A set of equations is given below:
Equation C: y = 7x + 12
Equation D: y = 7x + 2
How many solutions are there to the given set of equations?
O One solution
OTwo solutions
O Infinitely many solutions
No solution
Answer: No solution
Step-by-step explanation:
Ths lines are parallel (as they have the same slope but different y-intercepts), and parallel lines never intersect. Thus, the system has no solutions because the lines never intersect.
A line segment has endpoints at A(-2, 4) and B(-4, 2). Write an equation in slope-intercept form for a line that bisects this segments that is parallel to the line y = -2x + 5. (Hint: You will need to find the midpoint of the segment first so that you know a point that will be on your new line.)
Please enter A and B for your answer in the form: y = Ax + B
A=
B=
The equation of the line that bisects the given segment is y = -2x -3.
The given points coordinates;
A(-2, 4), B(-4, 2)
The mid-point of the given coordinate points;
\(Mid-point = \frac{x_1 + x_2 }{2} , \ \frac{y_1 + y_2}{2} \\\\Mid-point = \frac{-2 -4}{2} , \ \frac{4+2}{2} \\\\Mid-point = (-3, 3)\)
The slope of the given line is calculated as;
y = -2x + 5
slope = -2
The equation of the line that bisects the given coordinate points;
\(\frac{y-y_1}{x-x_1} = -2\\\\\frac{y-3}{x-(-3)} = -2\\\\\frac{y-3}{x+3} = -2\\\\y-3 = -2(x+3)\\\\y-3 = -2x -6\\\\y = -2x -3\)

Step-by-step explanation:
In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female
Number of Freshman = 60
Number of female = 55
Number of Freshman female 22
Total number of students = 100

analyze the worst-case time complexity of the algorithm you devised in exercise 35 of section 3.1 for finding the first term of a sequence less than the immediately preceding term.
The overall worst-case time complexity of the algorithm is O(n).
What is the worst-case time complexity for the algorithm described in exercise 35 of section 3.1?To analyze the worst-case time complexity of the algorithm from exercise 35 of section 3.1, we can follow these steps:
1. Review the algorithm: Recall the algorithm designed in exercise 35, which aims to find the first term of a sequence less than the immediately preceding term.
2. Identify the loop: The main part of the algorithm is a loop that iterates through the sequence of numbers, comparing each term to the previous one.
3. Count the operations: For each iteration of the loop, there are a constant number of operations, such as comparisons and variable assignments.
4. Determine the number of iterations: In the worst-case scenario, the algorithm has to iterate through the entire sequence to find the first term that is less than the immediately preceding term. If the sequence has n elements, the algorithm will have n-1 iterations, since we compare each element with its previous one.
5. Calculate the time complexity: Since each iteration takes a constant amount of time, and there are n-1 iterations in the worst case, the overall worst-case time complexity of the algorithm is O(n). This means that the time complexity grows linearly with the length of the input sequence.

Find the perimeter and area of a rectangle with length (6) and width (x + 2).
Answer:
The perimeter of a rectangle is: P = 2x+16
The area of a rectangle is: A = 6x+12.
Step-by-step explanation:
Given
The length of a rectangle = l = 6
The width of a rectangle = w = (x+2)
To determine
The perimeter of a rectangle = P
The area of a rectangle = A
Determining the Perimeter of a rectangle
The perimeter of a rectangle can be determined using the formula
P = 2(l+w)
substitute l = 6 and w = (x+2)
P = 2(6+x+2)
P = 2(8+x)
P = 2x+16
Therefore, the perimeter of a rectangle is: P = 2x+16
Determining the Area of a rectangle
The Area of a rectangle can be determined using the formula
A = lw
substitute l = 6 and w = (x+2)
A = (6)(x+2)

The ratio of cranberry juice to apple juice to orange juice in its simplest form is 1 : 2 : 3.
We have,
Let's assume that the drink contains a total of x units of liquid.
Now,
1/3 of the drink is apple juice, which is (1/3)x units of apple juice.
1/2 of the drink is orange juice, which is (1/2)x units of orange juice.
The rest of the drink is cranberry juice, which is x - (1/3)x - (1/2)x = (1/6)x units of cranberry juice.
To write the ratio of cranberry juice to apple juice to orange juice in its simplest form, we need to express these quantities in terms of a common unit.
So,
(1/3)x = (2/6)x
(1/2)x = (3/6)x
(1/6)x = (1/6)x
Therefore,
The ratio of cranberry juice to apple juice to orange juice is:
(1/6)x : (2/6)x : (3/6)x
Simplifying this ratio by dividing all terms by the greatest common factor of 6.

Two cars are traveling along a straight road. Car A maintains a constant speed of 77.0 km/h. Car B maintains a constant speed of 114 km/h. At t=0, car B is 45.0 km behind car A. How long does it take before car A is overtaken by car B?
Answer: 72.97 Minutes
Step-by-step explanation: We have two cars, A and B, traveling along a straight road. Car A is moving at a constant speed of 77.0 km/h, while car B is moving at a constant speed of 114 km/h. At the starting point (t=0), car B is 45.0 km behind car A.
To figure out how long it takes for car B to catch up and overtake car A, we need to consider their relative speeds. The relative speed is the difference between the speed of car B and the speed of car A.
Relative speed = Speed of car B - Speed of car A
Relative speed = 114 km/h - 77.0 km/h
Relative speed = 37.0 km/h
So, car B is moving 37.0 km/h faster than car A. Now, we need to determine the time it takes for car B to cover the initial distance between them, which is 45.0 km.
To calculate time, we use the formula: Time = Distance / Speed. In this case, the distance is 45.0 km, and the speed is the relative speed of 37.0 km/h.
Time = 45.0 km / 37.0 km/h ≈ 1.2162 hours
Now, let's convert the time to minutes by multiplying it by 60 (since there are 60 minutes in an hour).
Time = 1.2162 hours * 60 minutes/hour ≈ 72.97 minutes
Therefore, it takes approximately 1.2162 hours or 72.97 minutes for car B to catch up and overtake car A.

The horizontal distance between the base of the ladder and the wall is approximately 8.892 feet.
Here, we have,
To find the horizontal distance between the base of the ladder and the wall, we can use trigonometric functions.
In this case, the ladder forms an angle of 69 degrees with the ground. We can label this angle as θ.
We know the length of the ladder is 26 feet. We can label the horizontal distance as x.
Using trigonometric functions, specifically cosine, we have:
cos(θ) = adjacent/hypotenuse
cos(69) = x/26
To find x, we can rearrange the equation:
x = 26 * cos(69)
Using a calculator, we can calculate:
x ≈ 26 * 0.3420
x ≈ 8.892
Therefore, the horizontal distance between the base of the ladder and the wall is approximately 8.892 feet.

Given that TR(x)=20x and TC(x)=120+10x what is the break-even point?
The break-even point is the level of output at which total revenue (TR) equals total cost (TC). In this case, with TR(x) = 20x and TC(x) = 120 + 10x, we need to find the value of x where TR(x) = TC(x).
To find the break-even point, we set TR(x) equal to TC(x) and solve for x.
TR(x) = TC(x) can be expressed as:
20x = 120 + 10x
Simplifying the equation, we combine like terms:
20x - 10x = 120
10x = 120
To isolate x, we divide both sides of the equation by 10:
x = 12
Therefore, the break-even point occurs when x is equal to 12. At this level of output, the total revenue is equal to the total cost.

Which inequality is represented by the graph?(20 POINTS)
Answer:
C. y<5/3x-3
Step-by-step explanation:
First, treat this problem as if you were graphing a normal slope intercept form equation, y=mx+b, where m=slope and b=the y-intercept. To find the slope of the line, find two points on the graph and count the number of units up/down over the number of units right/left. You could also use the slope formula, (y2-y1)/(x2-x1).
Once you have the slope, which, in this equation, is 5/3, find b, the y-intercept. You can find it by seeing where the line intersects with the y-axis (the vertical axis). In this case, b=(-3).
If this was a normal line, the equation would be y=5/3x-3. However, it's an inequality, and we're not quite done yet. We can eliminate answer B.
Look closely at the line. If it's dotted, the symbol is either a less-than/greater-than symbol (< or >). That means the answer can be any number up to that OR any number above that, but not that exact number. If it's a solid line, that means it's either a less-than or equal-to/greater-than or equal-to symbol, which looks like < and >. That means the answer can be that number and any number up to it OR that number and any number above it. This graph shows a dotted line, so we can eliminate answer A.
Now, one of the hardest parts, though it's really quite easy. If an equation is less-than or less-than or equal-to, the shaded region (all the possibilities) would be below the line. This is easy to tell with a horizontal line, easy enough to tell with a diagonal line, and a little difficult with a vertical line. With a vertical line, think of a number line with a single point on it. Anything to the left of the point is less than the point, so you would shade to the left of the line. If an equation is greater-than or greater-than or equal-to, the shaded region would be above the line, because it's the opposite of less-than or less-than or equal-to. Because the shaded region is below the line, the symbol to use in this equation is < because the answer is unknown but definitely below that line, but not on the line, because it's not a solid line, which means the answer is included.
The inequality of this line is y<5/3x-3, which is listed as answer C. Hope that helped! Comment if it didn't make sense.

For the function shown below, the definite integral integral_0^10 f(x) dx is closest to which of the following? a.-8 b.4 c.-4 d.0 e.8
The provided function's definite integral from 0 to 10 is closest to 4.
The area of each zone that the function, the x-axis, and the two vertical lines at x = 0 and x = 10 bounds is added to form the definite integral of the function. The definite integral that results from adding up each of these areas is the one that is closest to 4. The area of the region above the x-axis is larger than the area of the region below the x-axis, which explains this. The area of the region above the x-axis is higher than the area below the x-axis because the function is rising across the interval. The overall area is closer to 4 since the area of the region below the x-axis is negative. As a result, 4 is the closest value for the definite integral of the 0–10 function.

Which statement describes the graph of this polynomial function?
f (x) = x Superscript 4 Baseline + x cubed minus 2 x squared
Answer:
The graph of the polynomial function f(x) = x^4 + x^3 - 2x^2 will depend on the behavior of the function as x approaches infinity and negative infinity, as well as the location and behavior of any local extrema.
To determine the behavior of the function as x approaches infinity and negative infinity, we can look at the leading term of the polynomial, which is x^4. As x becomes very large (either positive or negative), the x^4 term will dominate the expression, and f(x) will become very large in magnitude. Therefore, the graph of the function will approach positive or negative infinity as x approaches infinity or negative infinity, respectively.
To find any local extrema, we can take the derivative of the function and set it equal to zero:
f(x) = x^4 + x^3 - 2x^2
f'(x) = 4x^3 + 3x^2 - 4x
Setting f'(x) equal to zero, we get:
4x(x^2 + 3/4x - 1) = 0
The solutions to this equation are x = 0 and the roots of the quadratic expression x^2 + 3/4x - 1. Using the quadratic formula, we can find these roots to be:
x = (-3 ± sqrt(33))/8
Therefore, the critical points of the function are x = 0 and x = (-3 ± sqrt(33))/8.
To determine the behavior of the function near each critical point, we can use the second derivative test. Taking the second derivative of f(x), we get:
f''(x) = 12x^2 + 6x - 4
Evaluating f''(0), we get:
f''(0) = -4
Since f''(0) is negative, we know that x = 0 is a local maximum of the function.
Evaluating f''((-3 + sqrt(33))/8), we get:
f''((-3 + sqrt(33))/8) = 11 + 3 sqrt(33)/2
Since f''((-3 + sqrt(33))/8) is positive, we know that x = (-3 + sqrt(33))/8 is a local minimum of the function.
Evaluating f''((-3 - sqrt(33))/8), we get:
f''((-3 - sqrt(33))/8) = 11 - 3 sqrt(33)/2
Since f''((-3 - sqrt(33))/8) is also positive, we know that x = (-3 - sqrt(33))/8 is another local minimum of the function.
Based on this information, we can sketch the graph of the function as follows:
As x approaches negative infinity, the graph of the function approaches negative infinity.The function has a local maximum at x = 0.The function has two local minima at x = (-3 ± sqrt(33))/8.As x approaches infinity, the graph of the function approaches positive infinity.Therefore, the statement that describes the graph of this polynomial function is: "The graph of the function has a local maximum at x = 0 and two local minima at x = (-3 ± sqrt(33))/8. As x approaches infinity or negative infinity, the graph of the function approaches positive or negative infinity, respectively."
