7/3

Answer:

Well B is 6 and c is 12. So if you are finding out line segment Bc then all you have to do is combine bot h B and C. So you would get 6x12. If you could peroxide a graph that would be great.

So therefore the answer is 12

Step-by-step explanation:

GH = 18

From the diagram:

DF = 9x + 0

GH = 50 - 8x

Since G is a midpoint of DE and H is a midpoint of EF, using the midpoint theorem:

DF = 2GH

9x + 0 = 2 (50 - 8x)

9x = 100 - 16x

9x + 16x = 100

25x = 100

x = 100/25

x = 4

Substituting the value of x into GH = 50 - 8x

GH = 50 - 8(4)

GH = 50 - 32

GH = 18

Bear in mind that the sum of all the angles in a triangle is 180°.

Given two angles, we can easily find the third one.

Let's call it x.

Next, we set up an equation:

\(\sf{54+87+x=180}\)

\(\sf{141+x=180}\)

Subtract 141 on each side.

\(\sf{x=180-141}\)

\(\sf{x=39}\)

One way Olivia might have moved ABCDE onto A"B"C"D"E" is by first reflecting ABCDE over the x-axis, and then translating it 4 units to the left and 6 units down.

1) This would map point A to A", B to B", C to C", D to D", and E to E", creating A"B"C"D"E".

2) Angelica's transformation does not result in a figure that matches A"B"C"D"E". Reflecting ABCDE over the y-axis would map point A to A", B to E", C to D", D to C", and E to B", so the shape would be flipped horizontally. Translating it up 8 units would then shift the shape up, but it would still be horizontally flipped, so it would not match A"B"C"D"E".

3) Michael's claim is not correct. Translating ABCDE diagonally 8 units up and 10 units right would move point A to point J, which is not on A"B"C"D"E". The other points would also not be in their correct positions, so the resulting shape would not match A"B"C"D"E". To get to A"B"C"D"E" with one transformation, Michael would need to use a combination of translation, rotation, and/or reflection.

Answer:

11 and -11

Step-by-step explanation:

The square of 11 is 121. The square of -11 is also 121.

Answer:

Options C and F

Step-by-step explanation:

Check each answer:

6^2=36 but 36<64 so it cannot be A

8^2=64 but 64<64 (remember that even though they are equal to each other it doesn't meet the requirements of the inequality) so it cannot be B

11^2=121 and 121>64 so it can be C

-6^2=36 but 36<64 so it cannot be D (remember that squaring a number that is negative results in a positive number)

-8^2=64 but 64<64 so it cannot be E (see explanations for B and D)

-11^2=121 and 121>64 so it can be F

Therefore, the only two correct solutions are options C and F

The roots of the quadratic equation \(3x^2 - 14x - 5 = 0\), in exact square root form, are x = 5 and x = -1/3.

Using the quadratic formula to solve the quadratic equation \(3x^2 - 14x - 5 = 0\),we have

\(x = (-(-14) ± sqrt((-14)^2 - 4(3)(-5))) / (2(3))\\x = (14 ± sqrt(14^2 + 4(3)(5))) / (2(3))\\x = (14 ± sqrt(196 + 60)) / 6\\x = (14 ± sqrt(256)) / 6\\x = (14 ± 16) / 6\\\)

Therefore, the two roots of the quadratic equation in exact square root form are:

\(x = (14 + 16) / 6 = 5\\x = (14 - 16) / 6 = -1/3\\\)

Thus, the roots of the quadratic equation \(3x^2 - 14x - 5 = 0\), in exact square root form, are x = 5 and x = -1/3.

A quadratic equation is a second-degree polynomial equation in one variable of the form:

\(ax^2 + bx + c = 0\)

where x is the variable, and a, b, and c are constants. In this equation, the highest power of x is 2, and it is called the coefficient of x^2. The coefficient of x is b, and the constant term is c.

The quadratic equation is called "quadratic" because the highest power of x is a square (i.e., x^2), and the graph of the equation is a parabola.

The quadratic equation can have zero, one, or two real solutions, depending on the values of a, b, and c. The solutions can be found by using the quadratic formula:

\(x = (-b ± √(b^2 - 4ac)) / 2a\)

where the symbol ± means "plus or minus" and the square root is of the discriminant (b^2 - 4ac).

Answer:

Step-by-step explanation:

\(\frac{d}{dx} [cos(3x^2) \sqrt[3]{5x^3 -1} +sin(4x^3)]^4\\\\=4[cos(3x^2) \sqrt[3]{5x^3 -1} +sin(4x^3)]^3\; \frac{d}{dx} [cos(3x^2) \sqrt[3]{5x^3 -1} +sin(4x^3)] --- eq(1)\)

Lets look at the derivative part:

\(\frac{d}{dx} [cos(3x^2) \sqrt[3]{5x^3 -1} +sin(4x^3)] \\\\= \frac{d}{dx}[cos(3x^2) \sqrt[3]{5x^3 -1} ] + \frac{d}{dx}[sin(4x^3)]\\\\=cos(3x^2) \frac{d}{dx}[ \sqrt[3]{5x^3 -1} ] + \sqrt[3]{5x^3 -1}\frac{d}{dx}[ cos(3x^2) ] + cos(4x^3) \frac{d}{dx}[4x^3]\\\\=cos(3x^2) \frac{1}{3} (5x^3 -1)^{\frac{1}{3} -1} \frac{d}{dx}[5x^3 -1] + \sqrt[3]{5x^3 -1} (-sin(3x^2))\frac{d}{dx}[ 3x^2] + cos(4x^3)[(4)(3)x^2]\)

B) 352

Step-by-step explanation:

45% = 0.45

c. $1,293.40 is the Santos's monthly Social Security benefit, after delaying collecting for 2 years.

If Santos delays collecting his Social Security benefits for 2 years, he will be eligible for delayed retirement credits. The amount of the increase depends on his birth year and the specific rules in place at the time. As of my knowledge cutoff in September 2021, for individuals born in 1943 or later, the delayed retirement credit is 8% per year for each year of delay beyond full retirement age.

Assuming Santos's original benefit at full retirement age was $1,115.00, we can calculate the increase after a 2-year delay:

Increase = Original Benefit * (Delayed Retirement Credits per year * Number of years of delay)

Increase = $1,115.00 * (0.08 * 2)

Increase = $1,115.00 * 0.16

Increase = $178.40

To calculate Santos's monthly Social Security benefit after the 2-year delay, we add the increase to his original benefit:

New Benefit = Original Benefit + Increase

New Benefit = $1,115.00 + $178.40

New Benefit = $1,293.40

Santos's monthly Social Security benefit, after delaying collecting for 2 years, would be approximately $1,293.40. Therefore, Option c is correct.

Based on the given information, we can see that the book value of the vehicle 4 years after Joe bought it is R243,736.90. This point is given as Q(4; R243,736.90) on the graph.

To find out how much Joe paid for the vehicle, we need to look at the y-axis of the graph for the book value and find the corresponding value at x=0 (the time Joe bought it). From the graph, we can see that the book value of the vehicle at x=0 is R450,000. Therefore, Joe paid R450,000 for the vehicle.

(a) To calculate the percentage annual rate of depreciation using the reducing-balance method, we need to know the initial value of the vehicle, the salvage value, and the number of years over which it depreciates. However, this information is not provided in the question.

(b) To calculate the value of "a," we need to use the information from the graph of g, which shows the cost price of a similar vehicle x years later. However, the graph of g is not given in the question. Without the graph of g, we cannot calculate the value of "a."

(c) To calculate the monthly payment to the sinking fund, we can use the formula for the future value of an annuity:

FV = P * (((1 + r/n)^(nt) - 1) / (r/n))

where:

P = monthly payment

r = annual interest rate (6.2%)

n = number of times compounded per year (12 for monthly)

t = number of years (3.92 years, since payments start at the end of the 13th month and end at the end of the 48th month)

We want to find the value of P. We know that FV (the future value of the sinking fund) is equal to the replacement cost of the vehicle, which is R450,000. Plugging in the values and solving for P, we get:

450000 = P * (((1 + 0.062/12)^(12*3.92) - 1) / (0.062/12))

P = R7,687.28

Therefore, the monthly payment to the sinking fund should be R7,687.28.

(d) We have already determined that Joe paid R450,000 for the vehicle.

The inverse of matrix A, if it exists, is:

A^(-1) = [7/43, 2/43; 10/43, 9/43]

To find the inverse of a matrix A, we need to determine if the matrix is invertible by calculating its determinant. If the determinant is non-zero, then the matrix has an inverse.

Given the matrix A = [9, -2; -10, 7], we can calculate its determinant as follows:

det(A) = (9 * 7) - (-2 * -10)

= 63 - 20

= 43

Since the determinant is non-zero (43 ≠ 0), we can proceed to find the inverse of matrix A.

The formula to calculate the inverse of a 2x2 matrix is:

A^(-1) = (1/det(A)) * [d, -b; -c, a]

Plugging in the values from matrix A and the determinant, we have:

A^(-1) = (1/43) * [7, 2; 10, 9]

Simplifying further, we get:

A^(-1) = [7/43, 2/43; 10/43, 9/43].
