Answer:

Width of the rectangle is 19 Units

Step-by-step explanation:

24 = x(x-5)

24 = [tex]x^{2}[/tex] - 5x

[tex]x^{2}[/tex] - 5x - 24 = 0

x(x-24) + 1(x-24) = 0

(x-24)(x+1)=0
x= -1 , 24

x = 24 units

x - 5 = 19 units

Step-by-step explanation:

If you look at the picture above you'll see that after connecting the length, width and area you get a quadratic equation which I solved using formula method, but any method can be used to solve the quadratic equation.

The total production of both countries when they did not specialize was 91 million / day.

Given the information that when the two countries did not specialize, the total production of chinos was 23 million pairs per day, and the total production of pistachios was 68, we can calculate the total production of both countries with the following equation:

Total Production = Chinos (23 million pairs / day) + Pistachios (68 million / day)

Therefore, the total production of both countries when they did not specialize was 91 million / day. This can be calculated as:

Total Production = 23 million pairs + 68 million = 91 million / day

Hence, the total production of both countries when they did not specialize was 91 million / day. This calculation can be represented by the following formula:

Total Production = Chinos (x) + Pistachios (y)

Where x = 23 million pairs and y = 68 million.

Therefore, the total production of both countries when they did not specialize was 91 million / day.

Answer:

75%

Step-by-step explanation:

We know

A year has 12 months

Oliver worked 9 months out of the year

What percent of the year did he work?

We take

9 divided by 12, time 100 = 75%

So, he works 75% of the year.

The amount of time it takes for E to increase by 10%. it takes 4.81 seconds.

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth.

Given that,

Let the amount of time it takes for E to increase by 10% be x.

Thus, after (t + x) seconds, E is increased by 10%.

E(t + x) = E(t) + 10% of E(t)

= E(t) + 10/100 E(t)

= E(t) + 0.1 E(t)

E(t + x) / E(t) = 1.1

As,

[tex]E(t) = 6(1.02)^t\\\\E(t + x) = 6(1.02)^{t + x}\\\\\frac{E(t + x)}{E(t)} = \frac{6(1.02)^{t + x}}{6(1.02)^{t}}\\\\\frac{E(t + x)}{E(t)} = (1.02)^{t + x - t}\\\\(1.02)^x = 1.1[/tex]

Taking log on both sides:

x = log (1.1) / log (1.02)

x = 4.81 seconds.

Hence, the amount of time it takes for E to increase by 10%.

it takes 4.81 seconds.

9. f((5)) = -11

1. (f + j)(3) = f(3) + j(3) = (-3(3)+2) + (5-3) = -7 + 2 = -5

3. To find the value of (h + g)(-5), we need to first add the functions h(x) and g(x), then evaluate the result at x = -5.

h(x) = -2x + 9

g(x) = 5

h(x) + g(x) = -2x + 9 + 5 = -2x + 14

We can change x to 17 in the regression model y = 4.9x + 15.2 and calculate for y to get the number of victories for a squad with 17,000 spectators: y = 4.9(17) + 15.2 = 83.5

Consequently, 83.5 victories are expected for a squad with a 17,000-fan attendance.

To predict the number of wins for a team with an attendance of 17,000, we can substitute x = 17 into the regression equation y = 4.9x + 15.2 and solve for y:

y = 4.9(17) + 15.2 = 83.5

(200 - 100√2) / 16 is the rectangular form of the product c1*c2 for an equilateral triangle's vertices.

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon. Every triangle has three sides and three angles, which may or may not be the same.

Here,

An equilateral triangle is a triangle with three equal sides. If 3-2i, 6-i, and c form the vertices of an equilateral triangle, then the distance between 3-2i and 6-i is equal to the distance between 3-2i and c.

The distance between two complex numbers a + bi and c + di can be found using the formula:

√((c - a)² + (d - b)²)

So, the distance between 3-2i and 6-i is:

√((6 - 3)² + (-1 - (-2))²) = √((3)² + (1)²) = √(9 + 1) = √10

And the distance between 3-2i and c is:

√((c - 3)² + (c - (-2))²) = √((c - 3)² + (c + 2)²)

Since these distances must be equal, we have:

√((c - 3)² + (c + 2)²) = √10

Squaring both sides:

(c - 3)² + (c + 2)² = 10

Expanding both sides:

c² - 6c + 9 + c² + 4c + 4 = 10

Combining like terms:

2c² + 10c + 5 = 10

Subtracting 10 from both sides:

2c² + 10c - 5 = 0

This is a quadratic equation, which can be solved using the quadratic formula:

c = (-b ± √(b² - 4ac)) / 2a

Where a = 2, b = 10, and c = -5. Plugging these values into the formula:

c = (-10 ± √(10² - 4 * 2 * -5)) / 2 * 2

c = (-10 ± √(100 + 40)) / 4

c = (-10 ± √(140)) / 4

c = (-10 ± 10√2) / 4

So there are two complex solutions, c1 = (-10 + 10√2) / 4 and c2 = (-10 - 10√2) / 4.

The product of these two solutions is:

c1 * c2 = ((-10 + 10√2) / 4) * ((-10 - 10√2) / 4)

= (100 - 100√2 + 100) / 16

= (200 - 100√2) / 16

(200 - 100√2) / 16 is the answer in rectangular form for the product c1*c2 for the vertices of an equilateral triangle.

x = (300 - p) / 20

According to the equation, the quantity of kilos (x) of snig that will be sold is equal to the difference between 300 and p, divided by 20.

The price-demand connection for roast snig at the harvest festival on the planet Bozone can be represented by the equation p=300 - 20x. The formula specifies that 300 minus 20 times the number of kilogrammes (x) of snig sold is the price per kilogramme of snig (p) in the local currency (Bozats).

Using this equation, one can determine how much of the price must be reduced in order to sell 1 extra kilogramme of snig. The equation can be rewritten to solve for x in terms of p in order to accomplish this. This can be done by taking 300 off of both sides of the equation, multiplying both sides by 20, and then solving for x = (300 - p) / 20. This rearrangement has the effect of dividing the number of kilogrammes of snig that will be sold in terms of price per kilogramme by the difference between 300 and p. This equation can be used to calculate the price reduction required to sell an extra kilogramme of snig.

One possible choice for p(x) is x² - 1, and one possible choice for q(x) is x² + x - 2. These polynomials satisfy the required property (i.e., their derivatives at x=1 are equal to the polynomials themselves evaluated at x=1), and they are linearly independent because their leading terms (x² in both cases) are distinct.

An equation can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.

To determine whether the equations Ax = b are compatible and to compute a solution x, you would first form the augmented matrix [A|b]. Then, you would perform row operations on [A|b] to reduce it to an upper triangular matrix [C|d]. Finally, you would use the software package to solve the square system of equations Cx = d.

If the software terminates with an error message, it means that C is singular, and the equations Ax = b are not compatible. If the software finds the unique solution of Cx = d, it means that the equations Ax = b are compatible and that the solution x is unique. However, it is important to note that the uniqueness of the solution depends on the rank of A being equal to n. If the rank of A is less than n, the equations are not compatible, and if the rank of A is greater than n, the equations have infinitely many solutions.

For the given normal distribution, The 97th percentile of the cholesterol measurements is 218.8 mg/dL.

The normal distribution, also known as the Gaussian distribution or bell curve, is a continuous probability distribution that is symmetrical around its mean value. It is a widely used distribution in many fields, including finance, engineering, and the natural sciences, due to its important properties, such as the central limit theorem.

To find the 97th percentile of a normal distribution with mean 200 and standard deviation 10, we need to find the value x such that P(X < x) = 0.97, where X is a random variable representing the cholesterol measurement.

This value can be found using a standard normal distribution table (or Z-table), which gives the cumulative probabilities for a standard normal distribution with mean 0 and standard deviation 1.

We first standardize our random variable X by subtracting the mean and dividing by the standard deviation:

Z = (X - 200) / 10

So,

P(X < x) = P((X - 200) / 10 < (x - 200) / 10)

                   = P(Z < (x - 200) / 10) = 0.97.

Using the Z-table, we can find the Z-score corresponding to a cumulative probability of 0.97: Z = 1.88.

Finally, we can convert back to the original units for X by multiplying the Z-score by the standard deviation and adding the mean:

x = 10 * 1.88 + 200 = 218.8

So, the 97th percentile of the cholesterol measurements is 218.8 mg/dL.
