Answer:

B.   x = 7, y = 4√2

Step-by-step explanation:

Drop a vertical from the upper left corner

This creates a rectangle and a 45-45-90 triangle

The bottom of the rectangle is 3

The legs of the triangle are 4

Therefor

x = 4 + 3

x = 7

For a 45-45-90 triangle

the hypotenuse = leg * √2

y = 4√2

The possible variable terms are a2b3, a5b3, ab8, a3b5, a7b, and a6b5. These terms all contain the same number of a's and b's as the original expression, (2a4b)8.

The expansion of (2a 4b)8 can be found by multiplying the a coefficients and b coefficients by 8. The a coefficients would increase by a factor of 8 and the b coefficients would increase by a factor of 8. This means that the possible variable terms for (2a 4b)8 are all those that have 8 a's and 8 b's. This includes a2b3, a5b3, ab8, a3b5, a7b, and a6b5. These terms all contain the same number of a's and b's as the original expression, (2a4b)8, but with the coefficients multiplied by 8. For example, the term a2b3 would be the result of multiplying 2a4b by 8, which results in 16a32b. This can be simplified to a2b3. Similarly, a5b3 would be the result of multiplying 2a4b by 8, which results in 16a32b. This can be simplified to a5b3.

Based on the given responses, the student who factored 20x^6 = (2x)(10x^5) correctly is Andrei. Therefore, the correct answer is (Choice A) Andrei.

Among the given responses, the student who factored 20x^6 = 20, x to the power of 6 correctly is Andrei. Andrei's factorization is (2x)(10x^5), which correctly represents the original term 20x^6. Therefore, the correct answer is (Choice A) Andrei.

Amit's factorization is (4x^3)(5x^3), which is incorrect because it breaks down the term into two factors with the same exponent, while the original term has an exponent of 6.

Andrew's factorization is (20x^2)(x^3), which is also incorrect as it does not accurately represent the original term 20x^6.

Hence, the only student who correctly factored 20x^6 = 20, x to the power of 6 is Andrei.

The right answer is A. Andrei who factored 20x^6 = (2x)(10x^5) correctly.

Answer:

(14, 6 )

Step-by-step explanation:

Given

\(\frac{1}{7}\) x + \(\frac{1}{6}\) y = 3 ( multiply through by 42 to clear the fractions )

6x + 7y = 126 → (1)

\(\frac{1}{2}\) x - \(\frac{1}{3}\) y = 5 ( multiply through by 6 to clear the fractions )

3x - 2y = 30 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 6x + 4y = - 60 → (3)

Add (1) and (3)term by term to eliminate x

11y = 66 ( divide both sides by 11 )

y = 6

Substitute y = 6 into either of the 2 equations and evaluate for x

Substituting into (1)

6x + 7(6) = 126

6x + 42 = 126 ( subtract 42 from both sides )

6x = 84 ( divide both sides by 6 )

x = 14

Solution is (14, 6 )

The correct answer is option D which is f(x) is decreasing for all the values of x < 3.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

The value of the function \(f(x) = \dfrac{x+6}{x^2-9x+18}\) is represented on the graph in the graph we can see that at x>6 the value of the function is decreasing and at x<3 the value of the function is increasing.

Therefore the correct answer is option D which is f(x) is decreasing for all the values of x < 3.

Answer:

A

Step-by-step explanation:

To answer this question, we can use the following co-function identity:

\(\sin(\theta)=\cos(90\textdegree-\theta)\)

We know that sin(21°) is 0.36. This means that:

\(0.36=\sin(21\textdegree)=\cos(90\textdegree-21\textdegree)\)

Subtract within the cosine:

\(0.36=\sin(21\textdegree)=\cos(69\textdegree)\)

We can remove our second term:

\(\cos(69\textdegree)=0.36\)

So, our answer is A.

Answer:

X = 10

Z = 67

Step-by-step explanation:

We see that the angles are formed by the intersection of two lines.

Angles z and  67° are vertically opposite angles and therefore they are equal to each other

z°= 67°

Angles z and (7x + 43) are supplementary angles. The sum of these angles add up to 180°

z + 7x + 43 = 180

67 + 7x + 43 = 180

7x + 110 = 180

7x = 180 -110 = 70

x = 70/7 = 10

Answer:

Step-by-step explanation:

First you have to find out how many red were in the original 27 marbles.

If there were 7 Black and 4 Yellow - this is 11 so 27 - 11 = 16 RED.

Removing 3 Black - changes the the can to 24 marbles.

4 Black - 4 Yellow and 16 Red.

So probability the random pick is red after the removal of 3 Black is

16 out of 24.       \(\frac{16}{24}\)  

This reduces to 2/3.

Choice (K)

Answer:

Step-by-step explanation:

There are 27 marbles which include 7 black marbles

                                                            4 yellow marbles

Therefore, the number of red marbles=27-(7+4) marbles

                                                              =16 red marbles

When 3 black marbles are removed from the can, the total number of marbles become 24, which includes the 4 black marbles,4 yellow marbles and 16 red marbles.

So, the probability of the picking of a random red marble from the can after removing the black marbles = 16÷24

This when reduced gives the result 2÷3.

Hence, the answer is option K which means the probability that it was red is 2/3.

a) an upper bound for ET is 1/12.

b) The error ET is 1/2.

c) As a percentage of the true value of the integral, the error is 0%.

To estimate the integral ∫(1/x^2) dx from 1 to 2 with n = 4, we can use the trapezoidal rule.

a) To find an upper bound for the error ET, we can use the formula:

ET ≤ (b - a)^3 / (12n^2) * max|f''(x)|

In this case, a = 1, b = 2, and n = 4. The second derivative of f(x) = 1/x^2 is f''(x) = 2/x^4. We need to find the maximum value of f''(x) on the interval [1, 2].

Taking the derivative of f''(x), we get f'''(x) = -8/x^5. Since f'''(x) is negative for all x in the interval [1, 2], the maximum value of f''(x) occurs at x = 1.

Substituting these values into the error bound formula, we have:

ET ≤ (2 - 1)^3 / (12 * 4^2) * max|f''(x)|

ET ≤ 1 / 192 * (2/1)^4

ET ≤ 16/192

ET ≤ 1/12

Therefore, an upper bound for ET is 1/12.

b) To evaluate the integral directly, we have:

∫(1/x^2) dx = [-1/x] from 1 to 2

= (-1/2) - (-1/1)

= -1/2 + 1

= 1/2

c) To find the error ET, we subtract the estimated value from the true value of the integral:

ET = |True value - Estimated value|

ET = |1/2 - 1/2|

ET = 0

The error is 0, which means the estimated value using the trapezoidal rule is exact for this integral.

As a percentage of the true value of the integral, the error is 0%.
