Terry's house is 32 feet wide and the peak of the roof line is at 24 feet. write the absolute value equation to model the roof line
The peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:
y = |x - 16| + 24
This equation models the roof line of Terry's house.
To model the roof line of Terry's house, we can use the concept of absolute value. The equation for an absolute value function can be written as:
y = |x - h| + k
where (h, k) represents the vertex of the absolute value graph.
In this case, the peak of the roof line is at 24 feet. Since the width of the house is 32 feet, the vertex of the absolute value graph will be at the midpoint of the width, which is 16 feet. Therefore, h = 16.
Since the peak is at y = 24 feet, the vertex point (h, k) is (16, 24). Plugging these values into the equation, we get:
y = |x - 16| + 24
This equation models the roof line of Terry's house.

State whether the function graphed is continuous on [−1,3]. If not, where does it fail to be continuous and why? Is the function continuous on the interval [−1,3] ? If not, why? A. The function is continuous on the interval [−1,3]. B. The function is not continuous at x=1 because of an oscillating discontinuity. c. The function is not continuous at x=1 because of a removable discontinuity. D. The function is not continuous at x=1 because of a jump discontinuity.
The function is not continuous at x = 1 because of a removable discontinuity. Therefore, the correct option is C. The function is not continuous on the interval [−1,3].
In the first paragraph, we summarize the answer: The function is not continuous at x = 1 because of a removable discontinuity, and thus it is not continuous on the interval [−1,3].
Now let's explain the answer in more detail. A function is considered continuous at a point if three conditions are satisfied: the function is defined at that point, the limit of the function exists at that point, and the value of the function at that point is equal to the limit. In the given case, we can observe that the graph has a hole or gap at x = 1, indicating a discontinuity. This type of discontinuity is known as a removable discontinuity.
A removable discontinuity occurs when there is a hole in the graph, but it can be filled by redefining the function at that point. In other words, if we were to assign a value to the function at x = 1, the discontinuity would be removed, and the function would become continuous on the interval [−1,3]. The fact that the discontinuity is removable suggests that there might be a mathematical error or simplification that led to this gap in the graph. Therefore, the function is not continuous at x = 1 because of a removable discontinuity, and consequently, it is not continuous on the interval [−1,3].

Julie and Barry Spinos purchased a house for $96,400. They made a 25 percent down payment and financed the remaining amount at 5. 50 percent for 30 years. Their monthly payment is $410. 66. How much of the first monthly payment is used to reduce the principal?
The first monthly charge has about $78.78 allotted in the direction of reducing the principal.
The total buy charge of the house is $96,400 and the Spinoses made a 25% down payment, because of this they paid $96,400 x 0.25 = $24,100 in advance.
Therefore, the final quantity that they financed is $96,400 - $24,100 = $72,300.
They financed this amount at 5.50% for 30 years, which gives us the following method for calculating the monthly payment (P):
P = (r * PV) / (1 - (1 + r)^(-n))
in which:
r = month-to-month interest rate PV = present value n = overall range of paymentsSubstituting the values, we get:
P = (0.00458 * 72,300) / (1 - (1 + 0.00458)^(-360))
P ≈ $410.66
We recognise that the monthly payment is $410.66 and we will calculate the interest portion of the primary monthly price as follows:
interest = balance * monthly interest price
interest = $72,300 * (5.50% / 12) ≈ $331.88
To calculate the amount of the primary monthly charge this is used to lessen the fundamental, we subtract the interest component from the total monthly payment:
$410.66 - $331.88 ≈ $78.78
Thus, the first monthly charge has about $78.78 allotted in the direction of reducing the principal.

A garden table and a bench cost $992 combined. the garden table cost $92 more than the bench. what is the cost of the bench?
Let x be the cost of the bench. According to the question, the garden table costs $92 more than the bench.
Therefore, the cost of the garden table would be x + $92.
We know that the combined cost of the garden table and bench is $992.
That means we can write the following equation:x + (x + $92) = $992
Simplifying the above expression we get,2x + $92 = $992
Subtracting $92 from both sides of the equation:
2x = $900
Dividing both sides by 2:x = $450

a student of 9 engines contains 2 defective engines. an auto shop buys 4 engineers. what is the probability of the shop purchasing at least 3 non-defective engines?
The probability of the shop purchasing is 5/9.
How to find probability shop purchasing?Let X be the number of non-defective engines purchased by the auto shop out of the 4 engines bought. We want to find P(X >= 3), the probability of getting at least 3 non-defective engines.
Using the hypergeometric distribution formula, we have:
P(X >= 3) = P(X = 3) + P(X = 4)
where
P(X = k) = (C(7, k) * C(2, 4-k)) / C(9, 4)
So, we have:
P(X = 3) = (C(7, 3) * C(2, 1)) / C(9, 4) = (35 * 2) / 126 = 5/18
P(X = 4) = (C(7, 4) * C(2, 0)) / C(9, 4) = (35 * 1) / 126 = 5/18
Therefore,
P(X >= 3) = 5/18 + 5/18 = 10/18 = 5/9
So the probability of the shop purchasing at least 3 non-defective engines is 5/9.

Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 0 < x < 3.
Note: in decimal form, this fraction converts to roughly 34.67
=========================================================
Explanation:
Highlight the rows that have x = 0 and x = 3. Cross out or cover the other two rows up.
The two rows that have x = 0 and x = 3 show y = f(x) = 4 and y = 108 respectively.
So we have the two points (0,4) and (3,108). We need to find the slope of the line through these points to find the average rate of change from x = 0 to x = 3.
Turn to the slope formula
m = (y2-y1)/(x2-x1)
m = (108-4)/(3-0)
m = 104/3
We cannot reduce the fraction further.
Using a calculator,
104/3 = 34.67 approximately
what are the minimum and maximum numbers of elements in a heap of height h?
In a heap, the height is defined as the number of edges on the longest path from the root to a leaf node. The height of a heap with n elements is at most log₂(n+1).
To find the minimum and maximum numbers of elements in a heap of height h, we can use the formula:
The minimum number of elements in a heap of height h is 2^h (a complete binary tree of height h with the minimum number of nodes).
The maximum number of elements in a heap of height h is 2^(h+1) - 1 (a complete binary tree of height h with the maximum number of nodes).
Therefore, the minimum and maximum numbers of elements in a heap of height h are:
Minimum: 2^h
Maximum: 2^(h+1) - 1
Note that not all values of h are valid heap heights. A heap must be a complete binary tree, so its height can only take on values that satisfy the formula: \(h < = log₂(n+1),\)where n is the number of elements in the heap.

Kelley writes the expression n + 2 to model the phrase "Xander studied two more hours than Nandini." Which best explains the accuracy of Kelley's expression?
Answer:
Following are the solution to this question:
Step-by-step explanation:
It was right because the "Two" is "2," "more is" and "+" are two the most hours than Nandini and "n," so 2+n or n+2 is a true, phrase of Nandini's transcription".
Now, this vector n is unknown, so the number of hours Nandini researched should reflect.
Two further hours which Nandini researched Xander. So, Xander studied the number of hours = n + 2 or 2+ n. Kalley has therefore written a correct word.
Answer:
It is accurate. In the phrase “two more hours than Nandini,” “two” is “2,” “more” is “+,” and Nandini’s study time is unknown or “n,” so 2 + n or n + 2 are correct translations.

A dive bomber is flying from right to left along the graph of y=x 2. When a rocket bomb is released, it follows a path that is approximately along the tangent line. Where should the pilot release the bomb if the target is at (5,0) ? (Give your answer in the form (∗,∗). Express numbers in exact form. Use symbolic notation and fractions where needed.)
To determine where the pilot should release the bomb, we need to find the tangent line to the graph of y = x^2 at the point (5,0). First, let's find the derivative of the function y = x^2 to determine the slope of the tangent line. The derivative of y = x^2 is given by: \(dy/dx = 2x\)
Next, we can substitute the x-coordinate of the target point (5,0) into the derivative to find the slope at that point: \(dy/dx = 2(5) = 10\) So, the slope of the tangent line at (5,0) is 10. Now, we can use the point-slope form of a linear equation to write the equation of the tangent line: y - y1 = m(x - x1)
where (x1, y1) is the point (5,0) and m is the slope 10. Substituting the values, we have: y - 0 = 10(x - 5) Simplifying the equation, we get: y = 10x - 50 Therefore, the equation of the tangent line to the graph of y = x^2 at the point (5,0) is y = 10x - 50. To find where the pilot should release the bomb, we need to determine the x-coordinate when y = 0 (the target's y-coordinate). Setting y = 0 in the equation of the tangent line, we have: 0 = 10x - 50 Solving for x, we get: 10x = 50 x = 5 Therefore, the pilot should release the bomb at the point (5, 0).

B) 6x² + 20x + 2x² + 10x + 18
C) 2(4x² + 15x + 9)
D) 4(2x² + 7x + 4)
Answer:
A, C, and D
Step-by-step explanation:
A) (4x + 3) (2x + 6) is equal to 8x² + 30x + 18 because when you multiply two binomials, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, (4x + 3) (2x + 6) can be rewritten as (4x)(2x) + (4x)(6) + (3)(2x) + (3)(6). This can further be simplified to 8x² + 24x + 18.
C) 2(4x² + 15x + 9) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 2(4x² + 15x + 9) can be rewritten as 2(4x²) + 2(15x) + 2(9). This can further be simplified to 8x² + 30x + 18.
D) 4(2x² + 7x + 4) is equal to 8x² + 30x + 18 because when you multiply a number by a binomial, you use the distributive property. The distributive property states that for any numbers a, b, and c, a(b + c) = ab + ac. So, 4(2x² + 7x + 4) can be rewritten as 4(2x²) + 4(7x) + 4(4). This can further be simplified to 8x² + 28x + 16.
Find a particular solution to the nonhomogeneous differential equation y'' +4y' 5y = -5x + 5e^-x.
The particular solution to y'' + 4y' + 5y = -5x + 5e^(-x) is y_p(x) = (-1/2)x + (1/6)e^(-x). The general solution is y(x) = e^(-2x)(C1 cos(x) + C2 sin(x)) + y_p(x).
To find a particular solution to the non-homogeneous differential equation:
y'' + 4y' + 5y = -5x + 5e^(-x)
We can use the method of undetermined coefficients.
The characteristic equation for the homogeneous equation is:
r^2 + 4r + 5 = 0
which has roots r = -2 ± i.
Thus, the complementary solution is:
y_c(x) = e^(-2x)(C1 cos(x) + C2 sin(x))
Since the right-hand side of the non-homogeneous equation contains a polynomial term and an exponential term, we assume a particular solution of the form:
y_p(x) = Ax + Be^(-x)
Taking the first and second derivatives of y_p(x), we get:
y'_p(x) = A - Be^(-x)
y''_p(x) = Be^(-x)
Substituting these into the original equation, we get:
Be^(-x) + 4(A - Be^(-x)) + 5(Ax + Be^(-x)) = -5x + 5e^(-x)
Simplifying and equating coefficients, we get:
5A - 3B = -5
-3A + 9B = 5
Solving for A and B, we get:
A = -1/2
B = 1/6
Therefore, the particular solution is:
y_p(x) = (-1/2)x + (1/6)e^(-x)
The general solution to the non-homogeneous equation is:
y(x) = y_c(x) + y_p(x)
y(x) = e^(-2x)(C1 cos(x) + C2 sin(x)) + (-1/2)x + (1/6)e^(-x)
