Let f be a continuous function on the closed interval [0, 2] . If 2 ≤ f(x) ≤ 4, then the greatest
possible value of (integral from 0 to 2)f(x)dx is
a. 0
b. 2
c. 4
d. 8
e. 16
The correct answer is d. 8, as it represents the greatest possible value for the integral of f(x) over the interval [0, 2].
Given that 2 ≤ f(x) ≤ 4 for all x in the interval [0, 2], we know that the function f(x) is bounded between 2 and 4 throughout the interval. To find the greatest possible value of the integral of f(x) over the interval [0, 2], we want to maximize the area bounded by the function and the x-axis.
Since the function is continuous and bounded, we can use the Fundamental Theorem of Calculus to find the integral. The integral of f(x) over the interval [0, 2] represents the area under the curve of f(x) between x = 0 and x = 2.
The maximum possible value of this integral occurs when the function is at its upper bound of 4 throughout the interval. Therefore, the greatest possible value of the integral is the area of the rectangle with a base of 2 (the width of the interval) and a height of 4, which is 2 * 4 = 8.
Hence, the correct answer is d. 8, as it represents the greatest possible value for the integral of f(x) over the interval [0, 2].

The partial factorization of x2 – x – 12 is modeled with algebra tiles.
An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x, 3 are labeled +. 1 tile is in the Factor 2 spot and is labeled + x. 20 tiles are in the Product spot: 1 is labeled + x squared, 3 are labeled + x, the 4 tiles below + x squared are labeled negative x, and the 12 tiles below the + x tiles are labeled negative.
Which unit tiles are needed to complete the factorization?
Answer:
x² – x – 12 = (x – 4)(x + 3)
Step-by-step explanation:
Identify two numbers that add to -1 and multiply to -12, let's call them p and q.
So ax² + bx + c = (x + p)(x + q)
pq = c
p + q = b.
It is easier to find these numbers by finding factors of -12.
This can be done by splitting the number up until all the numbers are prime.
-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)
There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.
We can eliminate them by adding them up.
6 + -2 = 4 ≠ -1 so that can't be it.
-6 + 2 = -4 ≠ -1 so that can't be it either.
-3 + 4 = 1 ≠ -1
therefore p and q are 3 and -4 because 3 + -4 = -1.
so x² – x – 12 = (x – 4)(x + 3)
p = -4, and q = 3.
(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

What word is missing from this true mathematical statement: Twelve is congruent to 60 ______ 8 because both 12 and 60 have 4 as a remainder when divided by 8?
The missing word is "modulus". The statement should read: Twelve is congruent to 60 (modulus 8) because both 12 and 60 have 4 as a remainder when divided by 8.
The modulus function, also known as the modulo operation or mod function, is a mathematical operation that returns the remainder when one integer is divided by another. The modulo operation is a quick and efficient way to find the remainder of a division. For example, if we want to know the remainder when 23 is divided by 5, we can simply compute 23 % 5, which equals 3. The symbol "%" is often used to represent the modulo operation in computer programming, while "mod" is used in mathematical notation to indicate congruence. In either case, the statement means that 12 and 60 leave the same remainder when divided by 8.

The derivative of the function \(g(x) = ∫[1, x^3] t^3 dt is g'(x) = (3/4) x^11.\)
To find the derivative of the function \(g(x) = ∫[1, x^3] t^3\)dt using the Fundamental Theorem of Calculus, we can apply Part 1 of the theorem, which states that if the function g(x) is defined as the integral of a function f(t), then its derivative g'(x) can be found by evaluating f(x) at the upper limit of integration and multiplying it by the derivative of the upper limit.
In this case, the upper limit of integration is\(x^3\), so we have:
\(g'(x) = d/dx ∫[1, x^3] t^3 dt\)
Using the power rule for integration, we can integrate \(t^3\) to obtain (1/4) \(t^4\). Applying the Fundamental Theorem of Calculus, we have:
\(g'(x) = d/dx [(1/4) (x^3)^4]\)
Simplifying, we get:
\(g'(x) = d/dx [(1/4) x^12]\)
Taking the derivative using the power rule, we have:
\(g'(x) = (1/4) * 12x^(12-1)g'(x) = (3/4) x^11\)
Therefore, the derivative of the function \(g(x) = ∫[1, x^3] t^3 dt is g'(x) = (3/4) x^11.\)

The volume of the pyramid is approximately 5.9 cm³.
What is the volume of pyramid?To find the volume of a pyramid with a square base, you can use the formula:
Volume = (1/3) * base area * height
First, let's find the area of the square base. The perimeter of the base is given as 5.7 cm, which means each side of the square has a length of 5.7 cm / 4 = 1.425 cm.
The area of a square is given by the formula:
Area = side length * side length
Substituting the side length, we have:
Area = 1.425 cm * 1.425 cm = 2.030625 cm²
Now, we can calculate the volume of the pyramid:
Volume = (1/3) * base area * height
= (1/3) * 2.030625 cm² * 8.6 cm
= 5.91834375 cm³
Rounding to the nearest tenth of a cubic centimeter, the volume of the pyramid is approximately 5.9 cm³.

binomial a lottery will be held. from 1000 numbers, one will be chosen as the winner. a lottery ticket is a number between 1 and 1000. how many tickets do you need to buy in order for the probability of winning to be at least 50%?
we need to buy at least 694 tickets to have a probability of winning at least 50%.
We can use the binomial distribution formula to solve this problem. Let X be the number of tickets we need to buy to have a probability of winning at least 50%. Then:
P(X ≥ 1) ≥ 0.5
This means that the probability of winning with at least one ticket is at least 50%. We can find this probability using the complement rule:
P(X ≥ 1) = 1 - P(X = 0)
The probability of not winning with any ticket is:
P(X = 0) = (999/1000)^n
where n is the number of tickets we buy. Therefore:
1 - (999/1000)^n ≥ 0.5
Simplifying this inequality, we get:
(999/1000)^n ≤ 0.5
Taking the logarithm of both sides, we get:
n log(999/1000) ≤ log(0.5)
n ≥ log(0.5) / log(999/1000)
n ≥ 693.15
Therefore, we need to buy at least 694 tickets to have a probability of winning at least 50%.

construct orthogonal polynomials of degrees 0, 1, and 2 on the interval (0, 1) with respect to the weight function (a) w(x) = log x1 ( b ) w ( x ) = p1
The orthogonal polynomials with respect to the weight function (a) w(x) = log(x) on the interval (0, 1) are given by the Legendre polynomials. The orthogonal polynomials with respect to the weight function (b) w(x) = p^1 on the interval (0, 1) are the monomials.
(a) For the weight function w(x) = log(x), the orthogonal polynomials on the interval (0, 1) are defined by the Legendre polynomials. The Legendre polynomials are a set of orthogonal polynomials that satisfy a specific recurrence relation. The Legendre polynomial of degree 0 is simply a constant, denoted as P_0(x) = 1. The Legendre polynomial of degree 1 is P_1(x) = x. The Legendre polynomial of degree 2 is P_2(x) = (3x^2 - 1)/2. These polynomials are orthogonal with respect to the weight function w(x) = log(x) on the interval (0, 1).
(b) For the weight function w(x) = p^1, where p is a constant, the orthogonal polynomials on the interval (0, 1) are the monomials. Since the weight function is a constant, the inner product of two different monomials will be zero, making them orthogonal. The monomials are polynomials of the form x^n, where n is a non-negative integer. For example, the monomial of degree 0 is simply 1, the monomial of degree 1 is x, and the monomial of degree 2 is x^2. These monomials are orthogonal with respect to the weight function w(x) = p^1 on the interval (0, 1).

It takes 22 hours for a hosepipe with a flow of 12 litres per minute to fill a swimming pool. How long will it take if its flow is reduced to 5 litres per minute?
Answer:
t2 = 52.8 hours
it will take 52.8 hours if its flow is reduced to 5 litres per minute.
Step-by-step explanation:
The volume of the swimming pool can be written as;
Volume V = flow rate × time
V = R×t
V = R1×t1 = R2×t2
R1×t1 = R2×t2
t2 = R1×t1/R2 ........1
Given;
Flow rate R1 = 12 litres per minute
Flow rate R2 = 5 litres per minute
time t1 = 22 hours
Substituting the given values into equation 1;
t2 = R1×t1/R2 = 12×22/5
t2 = 52.8 hours
it will take 52.8 hours if its flow is reduced to 5 litres per minute.
For Anthony's birthday, his mother is making cupcakes for his 8 friends at his daycare. The recipe calls for 3 1/3 cups of flour. This recipe makes 2 1/2 dozen cupcakes. Anthony's mother has only 1 cup of flour. Is there enough flour for each of his friends to get a cupcake?
Answer:
Anthony mother's has enough flour for each of Anthony's friends to get a cupcake.
Step-by-step explanation:
Let suppose that Anthony and his friend will receive at least one cupcake, which means that Anthony's mother should make at least 9 cupcakes (\(\frac{3}{4}\) dozens).
From statement we notice that quantity of cupcakes is directly proportional to the quantity of flour.
According to the recipe, the required amount of flour and cupcakes are, respectively:
Flour
\(3\,\frac{1}{3}\,cups = 3 \,cups +\frac{1}{3}\,cups = \frac{10}{3}\,cups\)
Cupcakes
\(2\,\frac{1}{2}\,dozens = 2\,dozens +\frac{1}{2}\,dozens = \frac{5}{2}\,dozens\)
If Anthony's mother has 1 cup of flour at her disposal, the amount of cupcakes is obtained by simple rule of three:
\(x = \frac{5}{2}\,dozen\times\frac{1\,cup}{\frac{10}{3}\,cups }\)
\(x = \frac{3}{4}\,dozen\)
In a nutshell, Anthony mother's has enough flour for each of Anthony's friends to get a cupcake.
