Now, the first digit position in the numeral has 5 possible digit taking up its position

The second digit has 4 possible occupants

The last digit has 3 possible occupants

So the number of 3-digit numeral is the product of this three as follows;

Answer:

\( \frac{10}{100x {}^{2} + 1 } \)

Answer:

dy/dx=10/(1+100x^2)

Step-by-step explanation:

Let y=arctan(10x).

Then tan(y)=10x.

Differentiate both sides:

sec^2(y)×dy/dx=10

Divide both sides by sec^2(y):

dy/dx=10/sec^2(y)

By a Pythagorean identity:

dy/dx=10/(1+tan^2(y))

Recall tan(y)=10x:

dy/dx=10/(1+(10x)^2)

dy/dx=10/(1+100x^2)

Answer:

D. \sqrt(384)

Step-by-step explanation:

All you have to do is to expand the root the way I have done. I hope you understand and rate this answer well.

Don't forget 8 is the same as root(8) * root(8) which will give root(64) and the square root of 64 is 8.

The given expression represents the present value of a series of future cash flows discounted at a rate of 6.5% per year.

Each term in the expression represents a cash flow at a specific time in the future, and the denominator in each term represents the discount factor, which reflects the time value of money.

The first term, $250,000 / (1+0.065)^1, represents a cash flow of $250,000 that will be received in one year.

To determine its present value, we divide it by the discount factor (1+0.065)^1, which reflects the fact that the money will be received one year from now and is, therefore, less valuable than money received today.

Similarly, the second term, $37,500 / (1+0.065)², represents a cash flow of $37,500 that will be received in two years.

To determine its present value, we divide it by the discount factor (1+0.065)²,

which reflects the fact that the money will be received two years from now and is, therefore, less valuable than money received today.

This process is repeated for each term in the expression, representing cash flows that will be received in three, four, five, and six years, respectively.

The sum of these present values represents the total present value of the cash flows or the amount that they are worth today if they are discounted at a rate of 6.5% per year.

Answer:

36cm and 15cm

Step-by-step explanation:

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

Divide the dimensions of the map by the given ratio.

After the first reduction the dimensions of the new map are:

Therefore, the new dimensions of the map are 36cm and 15cm.

The final dimensions of the map are 72 cm by 30 cm.

If the map is enlarged twice in the ratio 3:5, this means that both the length and the width are multiplied by the same factor. Let the scale factor of the enlargement be x. Then, we have:

x = ( 5 /  3) x 2

x = 10 / 3

To find the final dimensions of the map, we multiply the original dimensions by the scale factor.

Final length = 21.6 cm x ( 10 / 3 ) = 72 cm

Final width = 9 cm x ( 10 / 3 ) = 30 cm

Hello!

\(\boxed{ \bf The~approximate~area~of~the~circle~is~D.~380~m^2}\)

___________________________________________

We must use a certain formula to find the area of a circle.

A = πr²

Let's plug in the radius.

A = π × 11²

A = π × 121

A = 380

Answer:

5√10

Step-by-step explanation:

The distance between two points A(\(x_1,y_1\)) and B(\(x_2,y_2\)) on the coordinate plane is given by:

\(|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }\)

From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).

Hence the lengths of the line segment EF and CD are:

\(|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}\)

Answer: The expected number of bulbs that would last longer than 22,250 hours is approximately 2,857.

Step-by-step explanation:

To solve this problem, we can start by finding the z-score for 22,250 using the formula:z = (x - mean) / standard deviationz = (22,250 - 20,000) / 2,250 = 1Next, we need to find the proportion of bulbs lasting longer than 22,250. We can look up this proportion in a standard normal distribution table or use a calculator, which gives us a probability of 0.1587.Finally, we can use this probability to find the expected number of bulbs that will last longer than 22,250:Expected number of bulbs = probability * total number of bulbs sold Expected number of bulbs = 0.1587 * 18,000 = 2,857Therefore, we can expect that approximately 2,857 of the 18,000 bulbs sold will last longer than 22,250 running hours.

Answer:

  128

Step-by-step explanation:

You want a prediction for x=2 when the given data is modeled by an exponential model.

A graphing calculator's exponential regression function models this data with the formula ...

  y = 135.7 · 0.9711^x

  y = 137.7 · 0.9711^2 ≈ 127.94 . . . . when x=2

This model gives a value for variable 2 of approximately 128 when variable 1 = 2.

The quantity of each food item that Nathan and Amanda should order for a graduation party with 35 guests, which is a function of ratio, is as follows:

Fried chicken  = 56 pieces

Lasagna = 24.5 lbs

Deli meats = 6.3 lbs

Sliced cheese = 52.5 pounds

Bakery buns = 3.5 dozens

Potato salad = 7 lbs

Ratio of 10 to 35 = 1 : 3.5 (35/10)

Amount of food for 10 party guests:

Fried chicken = 16 pieces

Lasagna = 7 lbs

Deli meats = 1.8 lbs

Sliced cheese = 15 pounds

Bakery buns = 1 dozen

Potato salad = 2 lbs

Fried chicken = 16 pieces x 3.5 = 56 pieces

Lasagna = 7 lbs x 3.5 = 24.5 lbs

Deli meats = 1.8 lbs x 3.5 = 6.3 lbs

Sliced cheese = 15 pounds x 3.5 = 52.5 pounds

Bakery buns = 1 dozen x 3.5 = 3.5 dozens

Potato salad = 2 lbs x 3.5 = 7 lbs

Thus, the quantity of each food item that Nathan and Amanda should order for a graduation party with 35 guests should be based on a ratio of 1:35.

The percentage of boys in the class and also the standard deviation of heights of all the students in the class are 78% and 9 cm respectively

Percentage of the boys in the class deals with a ratio of the boys to the number of students in the class

The given parameters that will help us to get the percentage are

Mean height of the class = 152 cm

Mean height of the boys = 158 cm

The standard deviation of the boys = 5 cm

Mean height of the girls = 148 cm

Standard deviation of the girls = 4 cm

(1) The percentage of boys in the class is

Total mean height = 158 +148 = 306

Percentage = 158/306 * 100 = 51.6%

Then the  percentages 51.6/100 * 152 = 78%

(2) The total standard deviation of all the students

Boys + girls = 5+4 = 9 cm

Therefore, the percentage of boys in the class and also the standard deviation of heights of all the students in the class are 78 students and 9 cm respectively

Answer:

$2,500 or 25%

Step-by-step explanation:

Let's use the same example:

Cost of Equipment = $10,000

Useful Life = 4 years

Depreciation Rate = (Annual Depreciation / Cost of Equipment) * 100

Annual Depreciation = Cost of Equipment / Useful Life

Annual Depreciation = $10,000 / 4 years

Annual Depreciation = $2,500

Depreciation Rate = ($2,500 / $10,000) * 100

Depreciation Rate = 0.25 * 100

Depreciation Rate = 25%

Answer:

$175,000.

Step-by-step explanation:

The amount of money that will be spent on specialty fees is $35,000,000 x 0.5% = $175,000.

Answer:

$175,000

Step-by-step explanation:

To calculate the amount of money that will be spent on specialty fees, we need to multiply the total amount of money raised (35,000,000) by the specialty fee percentage (0.5%).

fees = 35,000,000 * 0.005 = 175,000

So, $175,000 will be spent on specialty fees.

To calculate the amount of money that will be spent on service commission, we need to multiply the total amount of money raised (35,000,000) by the service commission percentage (2%).

commission = 35,000,000 * 0.02 = 700,000

So, $700,000 will be spent on service commission.

Using proportions, given the density value, it is found that the ballons contain 9.8 kilograms of helium.

A proportion is a fraction of a total amount.

In this problem, we have that each ballon contain 0.14 kilograms per cubic meter.

You get 5 ballons, each with 14 cubic meters, hence the total volume is given by:

V = 5 x 14 = 70 m³.

Applying the density, we have that the total mass is given by:

M = 0.14 x 70 = 9.8 kilograms.
