We are given that a trough is 8 ft long and has ends with the shape of isosceles triangles that are 2 ft across at the top and have a height of 1 ft. The trough is being filled with water at a rate of 11 ft³/min. We need to find out how fast the water level is rising when the water is 4 inches deep.

Let's first convert the depth of water from inches to feet.

1 inch = 1/12 ft

So, 4 inches = 4/12 ft = 1/3 ft

The volume of water in the trough is given by the formula:

V = lwh

where,

l = length of the trough = 8 ft

w = width of the trough (top width of the isosceles triangle) = 2 ft

h = depth of the water

We know that the height of the isosceles triangle is 1 ft. So, the height of the water is also h = 1 - 1/3 = 2/3 ft.

Substituting the values in the formula, we get:

V = 8 * 2 * (2/3)

V = 10.67 ft³

Now, we differentiate both sides of the formula with respect to time to get the rate of change of volume of water with respect to time.

dV/dt = l(dh/dt)w

We are given that the water is being filled at a rate of 11 ft³/min.

So, dV/dt = 11 ft³/min

l = 8 ft

w = 2 ft

Substituting the values, we get:

11 = 8 * (dh/dt) * 2

dh/dt = 11 / (8*2)

dh/dt = 0.6875 ft/min (approx)

Therefore, the water level is rising at a rate of 0.6875 ft/min when the water is 4 inches deep.

Answer:

Quarters = 20

Dimes = 14

Step-by-step explanation:

Dime = x = 10 cent = $0.1

Quarter = y = 25 cent = $0.25

x + y = 34 - - - (1)

0.1x + 0.25y = 6.40 - - - - (2)

From (1)

x = 34 - y

0.1(34 - y) + 0.25y = 6.40

3.4 - 0.1y + 0.25y = 6.40

3.4 + 0.15y = 6.40

0.15y = 6.40 - 3.40

0.15y = 3

y = 3 / 0.15

y = 20

x = 34 - y

x = 34 - 20

Answer: Part A. a student must find the missing length by using the Pythagorean theorem.

The answer should come out to be x=2√26 or x=−2√26 (Decimal: 10.19803902…, -10.19803902…) or (Rounded to the nearest tenth: 10.20, -10.20)

Step-by-step explanation:

Let's make x the missing length. The Pythagorean theorem says the way to set up this equation is the leg^2 + leg^2 = hypotnues^2.

Set up the problem and solve, I'll show you how to do it: x²+11²2=15²

Step 1: Simplify both sides of the equation.

x² + 121=225

Step 2: Subtract 121 from both sides.

x² + 121−121=225−121

x² = 104

Step 3: Take square root.

x = ± √104

The answer should come out to be x = 2√26 or x = −2√26 (Decimal: 10.19803902…, -10.19803902…) or (Rounded to the nearest tenth: 10.20, -10.20)

The sum of first 100 terms of the series is  0.686 with error less than 0.00005

The given series is

Tₙ = \(\frac{1}{n_3 +1 }\)

Since, \(\frac{1}{n_3 +1 } < \frac{1}{n_3}\)

The given series is convergent by the comparison Test.

The remainder Tₙ for the comparison series ∑ 1/n³ was estimated in this example using the remainder estimate for the Integral Test.

There we found that

\(T_n \leq \int\limits^\infty_n {\frac{1}{x^3} \, dx\)

Solving the integration,

=> \(\int\limits^\infty_n \frac{-1}{2x^2}\, dx\)

=> \(\frac{1}{2n^2}\)

So, \(T_n \leq \frac{1}{2n^2}\)

Therefore , the reminder Rₙ for the given series satisfies

Rₙ ≤ Tₙ ≤ 1/2n²

with n = 100 we have

=> R₁₀₀ ≤ 0.00005

Using a programmable calculator , we find that

\(\sum^\infty_{n=1} \frac{1}{n^3 + 1} = \sum^\infty_{100=1} \frac{1}{n^3 + 1}\)

=>  0.686 (approximately)

The roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x=-7 and x=1.

Any equation in algebra that can be written in the standard form where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation.

In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.

So, the roots of 0 = 2x² + 12x-14 are:

2x² + 12x-14  = 0

2x² + 14x - 2x -14

2x(x + 7) - 2(x + 7)

(2x - 2) (x + 7)

Now, use the zero product property as follows:

2x - 2 = 0

2x = 2

x = 2/2

x = 1

And

x + 7 = 0

x = -7

Therefore, the roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x = -7 and x = 1.

Number of red cards in deck = 26

Number of diamonds in deck = 13

Number of cards in deck = 52

Recall :

Probability = required outcome / Total possible outcomes

Probability of choosing a red :

P(red) = 26 / 52 = 1/2

With replacement :

Probability of diamond :

P(diamond) = 13 / 52 = 1/4

Hence,

Probability of first card red, then second card diamond equals

P(red) * P(diamond)

1/2 * 1/4

Median is better than mean as it is not affected by extremely high or low values in the same way that the mean is

The median is a measure of central tendency, like the mean, but it is not affected by extremely high or low values in the same way that the mean is. Because of this, the median is often a better measure of central tendency when there are outliers in the data, or when the data is skewed (not normally distributed). For example, consider the following set of numbers: 1, 2, 3, 100. The mean of these numbers is 26, but the median is 3, which is a better representation of the "typical" value in this set.

However, the mean is still a useful measure and has its own advantages. For example, the mean is sensitive to every value in the data set, so it can provide a more comprehensive summary of the data. Additionally, the mean is easier to work with mathematically than the median, so it is often used in statistical tests and calculations.

Step-by-step explanation:

The conditions on the positive numbers a, b, c, and d that will guarantee that every difference at every step in the expansion (a-b)(c-d) results in a positive number are:

1. a > b
2. c > d

This will ensure that the difference between a and b, as well as the difference between c and d, are both positive numbers. Therefore, when these two differences are multiplied together in the expansion (a-b)(c-d), the result will be a positive number.

For example, if a=5, b=2, c=8, and d=3, then the expansion (a-b)(c-d) will result in a positive number:

(5-2)(8-3) = (3)(5) = 15

As long as the conditions a > b and c > d are met, the expansion (a-b)(c-d) will result in a positive number.

The error sum of squares (SSE) is a measure of the variability or dispersion of the observed values around the regression line.

It is calculated by summing the squared differences between the observed values and the predicted values from the regression line. The formula for SSE is given by: SSE = Σ(yᵢ - ŷᵢ)². where yᵢ represents the observed values and ŷᵢ represents the predicted values from the regression line. In this case, the standard error of estimate (Se) is provided as 21, which is the square root of the mean squared error (MSE). Since the MSE is equal to SSE divided by the degrees of freedom (n - 2) for a simple regression problem, we can use this information to calculate SSE. Se² = MSE = SSE / (n - 2). Rearranging the equation: SSE = Se² * (n - 2). Substituting the given values: SSE = 21² * (12 - 2).SSE = 441 * 10. SSE = 4410. Therefore, the error sum of squares is 4410.

(a) A nonzero vector orthogonal to the plane through the points P, Q, and R is (9, -17, 35). (b) The area of triangle PQR is \(\sqrt\)(811) / 2.

(a) To determine a nonzero vector orthogonal to the plane through the points P, Q, and R, we can first find two vectors in the plane and then take their cross product. Taking vectors PQ and PR, we have:

PQ = Q - P = (5, 1, -2) - (-4, 0, 0) = (9, 1, -2)

PR = R - P = (6, 4, 1) - (-4, 0, 0) = (10, 4, 1)

Taking the cross product of PQ and PR, we have:

n = PQ x PR = (9, 1, -2) x (10, 4, 1)

Evaluating the cross product gives n = (9, -17, 35). Therefore, (9, -17, 35) is a nonzero vector orthogonal to the plane through points P, Q, and R.

(b) To determine the area of triangle PQR, we can use the magnitude of the cross product of vectors PQ and PR divided by 2. The magnitude of the cross product is given by:

|n| = \(\sqrt\)((9)^2 + (-17)^2 + (35)^2)

Evaluating the magnitude gives |n| = \(\sqrt\)(811).

The area of triangle PQR is then:

The Simplified form of the second expression is -1/3.

The given expression, let's break it down step by step:

Expression: (-7a^3b^-3) / (21ab)

First, let's simplify the numerator:

-7a^3b^-3 = -7 * (a^3) * (1/b^3) = -7a^3/b^3

Now, let's simplify the denominator:

21ab = 3 * 7 * a * b = 3 * (7ab)

Now, let's rewrite the expression with the simplified numerator and denominator:

(-7a^3/b^3) / (3 * 7ab)

Next, let's simplify further:

The -7 in the numerator can be cancelled out with the 7 in the denominator:

(-a^3/b^3) / (3 * a * b)

We can simplify further by canceling out the common factors in the numerator and denominator:

(-1/b^3) / (3 * a)

To divide by a fraction, we can multiply by its reciprocal:

(-1/b^3) * (1 / (3 * a))

This simplifies to:

-1 / (3 * a * b^3)

Therefore, the simplified form of the expression is -1 / (3 * a * b^3).

Now let's simplify the second expression:

Expression: (-3a^2b^4) * (1 / (3a^2 / b^4)) * (1 / (3b^2))

To simplify, we can multiply the terms and divide as necessary:

(-3a^2b^4) * (b^4 / (3a^2)) * (1 / (3b^2))

Simplifying further:

-3a^2b^4 * b^4 / (3a^2 * 3b^2)
