Write a quadratic equation given the x intercepts and other other point. Put steps together. Find the factors. Solve for a by substituting in the extra point. Write the equation in factored form.
Answer:
This question is clearly incomplete, so i will answer it in a really general way.
Suppose that for a quadratic function, we know that the x-intercepts are a and b.
And we also know that this function passes through the point (c, d).
First a definition, for a n-degree polynomial with the x-intercepts {x₁, x₂, ...,xₙ} and a leading coefficient K, we can write this polynomial in the factorized form as:
p(x) = K*(x - x₁)*(x - x₂)*...*(x - xₙ)
Now let's do the same for our quadratic function, we can write it as:
f(x) = K*(x - a)*(x - b)
(where a and b are known numbers)
Now we also know that this function passes through the point (c, d)
This means that:
f(c) = d
then:
d = K*(c - a)*(c - b)
With this equation we can find the value of K,
K = d/( (c-a)*(c - b))
Then the quadratic function is:
[tex]f(x) = d\frac{(x-a)}{(c-a)} \frac{(x-b)}{(c-b)}[/tex]
Where again, it is supposed that you know the values of a and b, and also the point (c, d)

2 people A and B travel from x and y talong different routes.Their journeys take the same amount of time
Question:
2 people A and B travel from X to Y along different routes. Their journeys take the same amount of time. B's route is 100km at an average speed of 40km/hour A's route is 60km. What is A's average speed?
Answer:
Person A's average speed is 24km/hr
Step-by-step explanation:
Given
Person B
[tex]Distance = 100km[/tex]
[tex]Speed = 40km/hr[/tex]
Person A
[tex]Distance = 60km[/tex]
Required
Average speed of person A
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
For person B
[tex]40 = \frac{100}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{100}{40}[/tex]
[tex]Time= 2.5hr[/tex]
For person A
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{60}{Time}[/tex]
The journeys last for the same duration.
So;
[tex]Speed = \frac{60}{2.5}[/tex]
[tex]Speed = 24[/tex]
Person A's average speed is 24km/hr

The approximation of I = *(x – 3)ex* dx by composite Trapezoidal rule with n= 4 is: -25.8387 15.4505 -5.1941 4.7846
The approximation of the integral ∫(x – 3)ex dx by the composite Trapezoidal rule with n = 4 is approximately: -5.1941.
To approximate the integral ∫(x – 3)ex dx using the composite Trapezoidal rule with n = 4, we divide the interval [a, b] into n subintervals of equal width. In this case, we don't have the limits of integration provided, so we'll assume the interval to be [a, b] = [a, a+4] for simplicity.
Let's denote h as the width of each subinterval, given by
[tex]h = (b - a) / n \\= 4 / 4 = 1[/tex]
Using the composite Trapezoidal rule formula, the approximation is given by:
[tex]Approximation = h/2 * [f(a) + 2*f(a + h) + 2*f(a + 2h) + ... + 2*f(a + (n-1)h) + f(b)][/tex]
Now, let's calculate the values of the function at each interval endpoint:
[tex]f(a) = (a - 3)*e^a\\f(a + h) = (a + h - 3)*e^{a + h}\\f(a + 2h) = (a + 2h - 3)*e^{a + 2h}\\f(a + 3h) = (a + 3h - 3)*e^{a + 3h}\\f(b) = (b - 3)*e^b[/tex]
[tex]Approximation = (1/2) * [(a - 3)*e^a + 2*(a + h - 3)*e^{a + h} + 2*(a + 2h - 3)*e^{a + 2h} + 2*(a + 3h - 3)*e^{a + 3h} + (b - 3)*e^b][/tex]

let and be two integers with 0≤<≤100 . suppose you approximate (≤100≤) by ∑=−11! . what is the largest possible error you could make?
The largest possible error you could make in the given approximation is [tex]1 / (10^11 * 11!)[/tex]
To approximate the value of [tex]e^x[/tex] using the series expansion, we can use the formula:
[tex]e^x[/tex] ≈ ∑ [tex](x^n)/n![/tex]
In this case, we have:
x = -1/10
To find the largest possible error in the approximation, we can consider the next term in the series that we are neglecting:
1 / (10^11 * 11!) = [tex]|x^(n+1) / (n+1)!|[/tex]
For the given approximation, n = 10 (since we are using terms up to n = 10).
Substituting the values, we have:
[tex]|Error|[/tex] = [tex]|(-1/10)^(10+1) / (10+1)!|[/tex]
|Error| =[tex]|(-1/10)^11 / 11!|[/tex]
|Error| =[tex]1 / (10^11 * 11!)[/tex]
Since the value of n is fixed at 10, the largest possible error occurs when x is at its maximum value within the given range (0 ≤ x ≤ 100).
In this case, the maximum value of |Error| would be obtained by using the maximum value of x = 100 in the formula.
|Error| = [tex]1 / (10^11 * 11!)[/tex]
Therefore, the largest possible error you could make in the given approximation is [tex]1 / (10^11 * 11!)[/tex].

Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)
an = ln(8n² + 9) − ln(n² + 9)
The limit of the sequence as n approaches infinity is ln(8). The sequence converges, and the limit is ln(8).
To determine whether the sequence given by an = ln(8n² + 9) − ln(n² + 9) converges or diverges, we can examine the behavior of the terms as n approaches infinity.
Taking the limit as n approaches infinity, we have:
lim(n→∞) ln(8n² + 9) − ln(n² + 9)
We can simplify this expression using logarithmic properties. The natural logarithm of a quotient is equal to the difference of the logarithms:
= lim(n→∞) ln[(8n² + 9)/(n² + 9)]
Now, let's analyze the behavior of the numerator and denominator as n approaches infinity:
As n becomes larger and larger, the higher-order terms dominate. In this case, the leading term in both the numerator and denominator is n².
In the numerator, 8n² dominates, and in the denominator, n² dominates. Therefore, as n approaches infinity, the ratio (8n² + 9)/(n² + 9) approaches 8.
Taking the natural logarithm of 8, we have ln(8).
Therefore, the limit of the sequence as n approaches infinity is ln(8).
Hence, the sequence converges, and the limit is ln(8).

(i) the polar coordinates of the point are (6, π/6).
(ii) the polar coordinates of the point are (-6, π/6).
The Cartesian coordinates of the point are given as (3√3, 3). We need to find the polar coordinates (r, θ) of the point, where r > 0 and 0 ≤ θ < 2π and also where r < 0 and 0 ≤ θ < 2π.
To find the polar coordinates (r, θ) of the point, we use the following formulas:
r = √(x² + y²)
θ = tan⁻¹(y/x)
where x and y are the Cartesian coordinates of the point.
(i). For r > 0 and 0 ≤ θ < 2π, we have:
x = 3√3
y = 3
Using the above formulas, we get:
r = √((3√3)² + 3²) = √(27 + 9) = √36 = 6
θ = tan⁻¹(3/3√3) = tan⁻¹(1/√3) = π/6
Therefore, the polar coordinates of the point are (6, π/6).

A. 5 to 0
B. 5 to 1
C. 5 to 2
D. 5 to 3
Answer:
A
Step-by-step explanation:
The required surface area is multiplied by a factor of 25 or 5 to 2. Option C is correct.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
The lateral surface area of a pyramid is given by the formula:
L = (1/2) * P * l
where P is the perimeter of the base and l is the slant height.
In this case, the perimeter of the base is 5 * 5 = 25 centimeters.
So the lateral surface area of the original pyramid is
L = (1/2) * 5 * 8 = 20 square centimeters.
Total area = 4[20] + 25 = 105
When the sides of the base and the slant height are each multiplied by 5, the new perimeter of the base is 5 * 5 * 5 = 125 centimeters and the new slant height is 8 * 5 = 40 centimeters.
So the lateral surface area of the new pyramid is
L = (1/2) * 25 * 40 = 500 square centimeters.
Total area = 4{500} + 125 = 2125
Therefore, the surface area is multiplied by a factor of 2125/105 = 25.

Step-by-step explanation:
The question is asking for the amount owed by each person. That just means you take the absolute value of their bank balance if their bank balance is negative. Absolute value is just how far away the number is from zero (basically when a number is negative, you're just making it positive).
Sophia owes $150, Malcolm owes $325, and Oren owes $275.
325 > 275 > 150
Thus Malcolm owes the most, since his amount owed is the highest.
