1. How many 5 digite numbers are there?
Answers
Answer:
90,000
Step-by-step explanation:
The first 5 digit number is 10,000, and the last 5 digit number is 99,999, so everything in between these numbers must be a 5 digit number.
You can find the number of numbers in between by subtracting them.
99,999 - 10,000 = 89,999
However, when subtracting, you leave out one of the numbers, so you add 1, which gives 90,000.
This can be shown with a smaller problem, such as how many 1 digit numbers are there:
1, 2, 3, 4, 5, 6, 7, 8, 9 - 9 numbers
However, when you subtract the biggest and smallest numbers:
9-1 = 8
As you see, you are missing on of the numbers because you didn't add one of the numbers in the problem.

To answer this question, we can proceed as follows:
\(7x^3\cdot(x^5+2x+3)\)Therefore, the answer is:
\(7x^8+14x^4+21x^3\)In this case, we need to multiply the monomial 7x^3 by each of the terms of the polynomial, using the method of the generic rectangle.
We sum the exponents, for example, (x^3 * x^5 = x^8) in each case, and also multiply the coefficients.
If you have 10 tennis players in a tournament with a round-robin setup, what is the total number of games they will need to play before each player has played every other player?
45, 15, 50, 8, 10, Any
Answers
In a 10-player round-robin tennis tournament, each player must play 45 games, and a total of 90 games will be played in the tournament.
A round-robin tournament is a type of competition in which every participant plays against every other participant. In a 10-player tournament, the number of games needed can be calculated using the formula for combination.
The density of a tournament can be defined as the number of games each player must participate in to play against every other player.
To calculate the density of a 10-player round-robin tournament, we use the formula
=> n(n-1)/2,
where n is the number of players.
In this case, n = 10. So, the density of the tournament is
=> 10(10-1)/2 = 45.
This means that each player must play 45 games in total, and each game involves 2 players.
So, there will be a total of
=> 45*2 = 90
games played in the tournament.
To summarize, The density of the tournament, 45 games per player, is calculated using the formula n(n-1)/2.

The volume of a rectangular pyramid is 64 units^3 . If the length of the rectangular base measures 4 units and the width of the rectangular base measures 6 units, find the height of the pyramid.
Answers
Given the word problem, we can deduce the following information:
Volume of a rectangular pyramid=64 units^3
length of the rectangular base = 4 units
width of the rectangular base = 6 units
To determine the height of the pyramid, we use the formula as shown below:
\(h=3\frac{V}{lw}\)where:
V= Volume of the rectangular pyramid
l=length of the rectangular base
w=width of the rectangular base
h=height of the pyramid
We plug in what we know:
\(\begin{gathered} h=3\frac{V}{lw} \\ =3\frac{64}{(4)(6)} \\ \text{Simplify} \\ =\frac{192}{24} \\ h=8\text{ units} \end{gathered}\)Therefore, the height of the pyramid is 8 units.

The unit of measure appropriate is cubic metre (m³)
Find the annual percentage yield (APY) for the investment. $8000 at 4.75% compounded daily The annual percentage yield (APY) is%. (Type an integer or decimal rounded to three decimal places as needed.)
Answers
Answer:
The annual percentage yield (APY) is a measure of the return on an investment that takes into account the effect of compounding interest. To calculate the APY for an investment of $8000 at an interest rate of 4.75% compounded daily, you can use the formula:
APY = (1 + r/n)^(n*t) - 1
where r is the annual interest rate as a decimal (0.0475 in this case), n is the number of times the interest is compounded per year (365 for daily compounding), and t is the number of years (1 in this case).
Plugging these values into the formula gives:
APY = (1 + 0.0475/365)^(365*1) - 1 APY ≈ 0.0486
So, the APY for this investment is approximately 4.86%.

Which is a true statement regarding Springside?
Springside does not affect the correlation.
Springside weakens the correlation shown in the scatterplot.
Springside strengthens the correlation shown in the scatterplot.
Removing Springside would increase the value of the correlation coefficient.
Answers
Interpreting the scatterplot, it is found that the correct option is:
Springside weakens the correlation shown in the scatterplot.
In the scatterplot, the mean test score is plotted as function of the mean class-size.From this, we can verify that as the mean class size increases, the mean score decreases, that is, there is a negative correlation between the mean class size and the mean test score.However, for Springside, the mean test score is greater than most other schools with smaller class sizes, which is a different result than expected, thus, it weakens the correlation, and the correct option is:Springside weakens the correlation shown in the scatterplot.

a circle has central angle 144° and its arc length is 4 units. the radius of the circle is
Answers
The radius of the circle with a central angle of 144° and arc length of 4 units is approximately 1.5915 units.
The length of an arc in a circle can be found using the formula:
Arc Length = (Central Angle/360)(2πr)
Where the central angle is measured in degrees, π (pi) is approximately equal to 3.14, and r is the radius of the circle.
In this case, the central angle is 144° and the arc length is 4 units. Plug in the values and solve for the radius of the circle.
4 = (144/360)(2πr)
Solving for r, we can isolate it on one side:
r = 4 / ((144/360)(2π) = 4 / (0.4)(2π) = 1.5915 units
Therefore, the radius of the circle is approximately 1.5915 units.

Suppose we take y= 9 and x= 3 then
9/3 > 1
3>1
Also

The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.

The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.
3. Total distance = Speed * time

A wire is bent into a circular coil of radius r=4.8 cm with 21 turns clockwise, then continues and is bent into a square coil (length 2r ) with 39 turns counterclockwise. A current of 11.8 mA is running through the coil, and a 0.350 T magnetic field is applied to the plane of the coil. (a) What is the magnitude of the magnetic dipole moment of the coil? A ⋅m
2
(b) What is the magnitude of the torque acting on the coil? N=m
Answers
The magnitude of the magnetic dipole moment of the coil is approximately 0.079 A·m². The magnitude of the torque acting on the coil is approximately 0.068 N·m.
(a) To find the magnitude of the magnetic dipole moment (M) of the coil, we can use the formula M = NIA, where N is the number of turns, I is the current flowing through the coil, and A is the area of the coil. For the circular coil, the area is given by A = πr², where r is the radius. Substituting the values N = 21, I = 11.8 mA = 0.0118 A, and r = 4.8 cm = 0.048 m, we can calculate the magnetic dipole moment as M = NIA = 21 * 0.0118 * π * (0.048)² ≈ 0.079 A·m².
(b) The torque acting on the coil can be calculated using the formula τ = M x B, where M is the magnetic dipole moment and B is the magnetic field strength. The magnitude of the torque is given by |τ| = M * B, where |τ| is the absolute value of the torque. Substituting the values M ≈ 0.079 A·m² and B = 0.350 T, we can calculate the magnitude of the torque as |τ| = M * B ≈ 0.079 A·m² * 0.350 T ≈ 0.068 N·m.
Therefore, the magnitude of the magnetic dipole moment of the coil is approximately 0.079 A·m², and the magnitude of the torque acting on the coil is approximately 0.068 N·m.

Answers
The total return over the year is 15.46%. The dividend yield is 7.21%, and the capital gain rate is 15.46%.
The price of a stock is equal to the current dividend plus the present value of all future dividends plus the price in one year. As a result, the share price of SPCC after a year will be:$112 = $7 + $105 + PV$PV = $0
Using the formula of the total return of an asset, which is equal to its capital gain plus dividend yield, we have;Total Return = Capital Gain + Dividend YieldCapital Gain = (Ending Price - Initial Price) / Initial PriceCapital Gain = ($112 - $97) / $97 = 0.1546 or 15.46%Dividend Yield = Annual Dividend per Share / Initial PriceDividend Yield = $7 / $97 = 0.0721 or 7.21%
Therefore, the total return over the year is 15.46%. The dividend yield is 7.21%, and the capital gain rate is 15.46%.

Step 2:
x and y are linear pairs, forming a supplementary angle.
Therefore,
