Answer:

The length of a is 36 mm.

Step-by-step explanation:

Similar rectangles have the same shape, but can have different sizes. The ratio of the lengths of corresponding sides of similar rectangles is always the same.

Given that b = 18 mm, c = 24 mm, and d = 36 mm, the ratio of the lengths of corresponding sides of the two rectangles is c/d = 24/36 = 2/3.

So, the length of a is equal to b * (c/d) = 18 * (2/3) = 36 mm.

The given cubic equation has no roots.

Traditionally, a cubic problem can be solved by converting it into a quadratic equation, which can then be solved by factoring or the quadratic formula. A cubic equation has three roots, just like a quadratic equation has two. Three real roots or one real root and two imaginary roots are both possible for a cubic equation. Cubic equations must also always be arranged in their standard form first.

The following strategies can be used to resolve a cubic equation:

Using Graphical Method to Find Integer Solutions with Factor Lists

Given that the cubic equation is: 8x²-5x³+7-12x

Regrouping the equation in standard form:

- 5x³ + 8x² - 12x + 7

Here, the constant is 7. Take the factors of the constant.

7 = 1, 7

Substitute the value of the factors as follows:

G(1) = - 5(1)³ + 8(1)² - 12(1) + 7 = -5 + 8 - 12 + 7 ≠ 0

G(7) = -5(7)³ + 8(7)² -12(7) + 7 = -1715 + 392 - 84 + 7 ≠ 0

Answer:its a cool song

Step-by-step explanation:

listening, listened to it, its good

Step-by-step explanation:

The rate of change of the population is proportional to the population, so we can use the exponential growth formula:

P(t) = P0 * e^(kt)

Where P0 is the initial population (300), k is the constant of proportionality, and t is the time in hours. We can use the data from t=24 hours to solve for k:

1000 = 300 * e^(24k)

Dividing both sides by 300 and taking the natural logarithm of both sides:

ln(1000/300) = 24k

ln(3.33) = 24k

k = ln(3.33) / 24

Now that we have k, we can plug it into the formula and solve for t when P(t) = 500:

P(t) = 300 * e^(kt)

500 = 300 * e^(kt)

e^(kt) = 500/300

e^(kt) = 5/3

kt = ln(5/3)

t = ln(5/3) / k

Substituting k = ln(3.33) / 24:

t = ln(5/3) / (ln(3.33) / 24)

t ≈ 11.7 hours.

Answer:

The first one is 76°, second one is 38°, third one is 66°

Step-by-step explanation:

Suppose the second one is x, given the first one is twice of the second one, so the first one is 2x.

2x+x+(28°+x)=180°

4x=152°

x=38

So, the first one is 76°, second one is 38°, third one is 66°

Answer: The amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.

Step-by-step explanation:

Let's denote the amount invested at 6% as "x". Then, the amount invested at 9% would be "y", and the amount invested at 15% would be "z".

According to the problem, we have the following information:

x + y + z = $7500 (the total amount invested)

0.06x + 0.09y + 0.15z = $867 (the total annual income)

And,

z = x + y + $100 (the amount invested at 15% was $100 more than the amounts invested at 6% and 9% combined)

We can substitute the third equation into the first equation to get:

x + y + x + y + $100 = $7500

Simplifying:

2x + 2y + $100 = $7500

2x + 2y = $7400

Next, we can substitute "z = x + y + $100" into the second equation:

0.06x + 0.09y + 0.15(x + y + $100) = $867

Expanding:

0.06x + 0.09y + 0.15x + 0.15y + 0.15 * $100 = $867

0.21x + 0.24y + $15 = $867

0.21x + 0.24y = $852

Finally, we can solve for x and y using the equations "2x + 2y = $7400" and "0.21x + 0.24y = $852".

We can use elimination method to find x:

2x + 2y = $7400

0.21x + 0.24y = $852

Multiplying the first equation by 0.21:

0.42x + 0.42y = $1557.8

Subtracting the second equation from the first:

0.42x + 0.42y - 0.21x - 0.24y = $1557.8 - $852

0.21x - 0.03y = $705.8

Dividing both sides by 0.21:

x = $705.8 / 0.21 + 0.03y / 0.21

x = $3357.14 / 0.24 + y

Finally, substituting x back into the equation "2x + 2y = $7400":

2($3357.14 / 0.24 + y) + 2y = $7400

Expanding:

$6714.29 + 2.24y = $7400

Solving for y:

2.24y = $7400 - $6714.29

y = $685.71 / 2.24

y = $306.13

And finally, substituting y back into the equation "x = $3357.14 / 0.24 + y":

x = $3357.14 / 0.24 + $306.13

x = $1393.57

Therefore, the amount invested at 6% was $1393.57, the amount invested at 9% was $306.13, and the amount invested at 15% was $1393.57 + $306.13 + $100 = $1800.70.

1. The company’s degree of operating leverage is 4.

2. The degree of operating leverage is 3.34.

3. The new contribution is $17, 280.

How much a company's operating income alters in reaction to a change in sales is measured by the level of operating leverage.

1. Degree of operating leverage = Contribution /Net Operating Income

and, Contribution = 54,000

Net Operating Income = $13,500

Thus, operating Leverage = 54000/ 13500  = 4

2. If Company's sales increase by 7% then contribution also increases by 7%,

Revised Contribution = $54000 + 7% = $57780

and, Revised net Operating income = $57780- $40500

                                                            = 17280

Degree of operating leverage = 57780 / 17280  = 3.34

3. Contribution format income statement:

Sales = $90000+ 7% = $96,300

Less: Variable Cost 36, 000 + 7% = $38520

So, New Contribution = 57780 - 40500 = $17, 280.

The total amount of Investment A is $6,348.58.

What is the compound interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.

To find the total amount of investment A, you can use the formula for compound interest:

A = P * (1 + r/n)⁽ⁿᵗ⁾

Where P is the initial investment ($5,000), r is the annual interest rate (6%), n is the number of times interest is compounded per year (2 times), and t is the number of years invested (4).

A = 5000 * (1 + 0.06/2)⁽²*⁴⁾

= 5000 * (1 + 0.03)⁸

= 5000 * 1.03⁸

= 5000 * 1.269716

What is a three-variable linear equation?

When a, b, and c are constants, a linear equation in two variables has the form ax + by + c = 0. (real numbers). Similar to this, a three-variable linear equation has the form ax by c z plus d = 0, where a, b, c, and d are constants.

Let's call the three numbers x, y, and z, where x is the largest number and z is the smallest number. Then, we have the following information:

x + y + z = 54

x - z = 46

y + z = 13

From the second equation, we can find z:

z = x - 46

Substituting this into the third equation:

y + x - 46 = 13

y = 13 + 46 - x

Substituting both of these into the first equation:

x + (13 + 46 - x) + (x - 46) = 54

Expanding the parentheses:

2x = 154

Dividing both sides by 2:

x = 77

Substituting this value of x into the equation for z:

z = x - 46 = 77 - 46 = 31

And substituting it into the equation for y:

y = 13 + 46 - x = 13 + 46 - 77 = -18

Note that these values do not satisfy the requirement that x, y, and z be positive numbers, so the problem does not have a solution.
