Answer:

180 cmStep-by-step explanation:

Öncelikle verilen A ve B ifadelerinin değerlerini hesaplayalım:

A = (sin x . sec x)² - (tan x . cosec x)²

A = (sin x / cos x)² - (sin x / cos x)²

A = sin² x / cos² x - sin² x / cos² x

A = 0

B = 2 - 2cos² x + cos⁴ x - sin⁴ x

B = 2 - 2cos² x + (cos² x)² - (sin² x)²

B = (cos² x)² - 2cos² x + 2

Şimdi 2A + 3B'yi hesaplayalım:

2A + 3B = 2(0) + 3[(cos² x)² - 2cos² x + 2]

2A + 3B = 3cos⁴ x - 6cos² x + 6

Bu şekilde 2A + 3B ifadesinin ayrıntılı hesaplanması tamamlanmış oldu.

The multiplication of the given two matrices A and B gives,

AB = [tex]\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right][/tex]

Given two matrices,

A = [tex]\left[\begin{array}{ccc}1&3&-1\\3&0&3\end{array}\right][/tex] and B = [tex]\left[\begin{array}{ccc}3&0\\-4&1\\0&3\end{array}\right][/tex]

We have to find the product of these matrices.

We have to multiply each row of A with each column of B.3

(AB)₁₁ = (1 × 3) + (3 × -4) + (-1 × 0) = -9

(AB)₁₂ = (1 × 0) + (3 × 1) + (-1 × 3) = 0

(AB)₂₁ = (3 × 3) + (0 × -4) + (3 × 0) = 9

(AB)₂₂ = (3 × 0) + (0 × 1) + (3 × 3) = 9

Hence the product is,

AB = [tex]\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right][/tex]

Hence the product is AB = [tex]\left[\begin{array}{ccc}-9&0\\9&9\end{array}\right][/tex].

Two years ago, an investment of R1 500000 has increased to R1 700000 and has delivered R40 000 worth of dividends over the two years. Then the return on investment would be 16%.

We can use the following formula to calculate ROI:

ROI = (gain from investment - cost of investment) / cost of investment

where, gain from investment is the total value of the investment (including dividends), and cost of investment is the initial investment.

Using the values given in the question, we can calculate the ROI as:

ROI = ((R1,700,000 + R40,000) - R1,500,000) / R1,500,000 = R240,000 / R1,500,000

ROI = 0.16 or 16%

The solution to the set of equations are:

x = 17/7

y = 20/7

We have,

The two equations are:

x + y = 7 ______(1)

x² - y² = 15 _______(2)

We can use the method of substitution.

From the first equation.

y = 7 - x

We can substitute this expression for y into the second equation.

x² - (7 - x)² = 15

Expanding the square in the second term gives:

x² - (49 - 14x + x²) = 15

Simplifying this equation.

-14x + 34 = 0

Solving for x gives:

x = 17/7

Substituting this value of x into the first equation.

y = 7 - x = 20/7

Answer:

A golden rectangle is a rectangle whose length and width are in the golden ratio, which is approximately 1.618. This means that if one side of the rectangle is x, then the other side is approximately 1.618x.

In this case, we know that one side of the rectangle is 0.82 centimeters. To find the length of the other side, we can multiply this value by the golden ratio:

1.618 × 0.82 ≈ 1.327

Therefore, the length of the other side of the rectangle is approximately 1.327 centimeters.

The number of students have not paid for the trip is 0.

Given that, there are 30 students in her class.

The indefinite integral of ∫ (4x⁴ - 5)⁵ . 32x³ dx is (4x⁴ - 5)⁶/3 + C.

The solution of the indefinite integral is calculated by using substitution method.

Let u = 4x⁴ - 5

du/dx = 16x³

dx = du/(16x³)

After burning for x hours, the candle's length, y, is calculated using the formula: y = 9 - (1/2)x.

Let y represent the length of the candle that is still burning after burning for x hours.

Since the candle burns at a rate of 1/2 inch per hour, we can use the following equation to explain the connection between the candle's length and the number of hours burned:

y = 9 - (1/2)x

Here, 9 represents the original length of the candle, and (1/2)x represents the length of the candle burned after x hours.

By subtracting the length burned from the original length, we obtain the length remaining after x hours.

Therefore, the function that determines the length of the candle, y, after burning for x number of hours is:

The numbers closest to the middle of the squares of consecutive integers around 69² are 4624 and 4761, which are at the squares of 68 and 69, respectively.

To find the number closest to the middle of the squares of consecutive integers around 69², we can use the fact that the squares of consecutive integers increase by an odd number. Specifically, the difference between the squares of consecutive integers n and n+1 is

(n+1)² - n² = 2n + 1

Therefore, the squares of consecutive integers around 69² are

67² = 4489

68² = 4624

69² = 4761

70² = 4900

71² = 5041

The middle of these squares is between 69² and 70², which is

(69² + 70²)/2 = 9674.5

So, we want to find the squares of the integers closest to 9674.5. Since 69 is closer to 9674.5 than 70, the two squares that are closest are

[tex]x=4.865[/tex]

Step-by-step explanation:

We know the area of a rectangle to be [tex]base*height[/tex]. In this instance, [tex]base=(2x+10)in[/tex], [tex]height=(3x) in[/tex], and [tex]area=288in^2[/tex]

The next step is to plug these known values into the [tex]area=base*height[/tex] equation. It'll look like this:

[tex]288=(2x+10)*(3x)=6x^2+30x[/tex]

This simplifies to:

[tex]48=x^2+5x[/tex]

Next, we want to rewrite the equation so we can apply the quadratic formula to it. We are going to do this by subtracting 48 from each side. The new equation looks like this:

[tex]x^2+5x-48=0[/tex]

Next, we plug this into the quadratic formula:

[tex]x=\frac{-(5)+\sqrt{5^2-4(1)(-48)} }{2(1)}=4.865[/tex]

[tex]x=\frac{-(5)-\sqrt{5^2-4(1)(-48)} }{2(1)}=-9.865[/tex]

The second value of x is negative, and since a side length cannot be negative this leaves us with just the first answer of [tex]x=4.865[/tex].
