Answer:

72

Step-by-step explanation:

For a five-digit number to be odd it's one digit must be 1,3,5.

So there can be no repeats of any digits.

Let's look at numbers with one's digit being 1.

There are 4 ways to choose the tabs digit.

After that you can choose the hundreds digit 3 ways.

The thousands digit can then be chosen 2 ways.

Then finally the ten-thousands digit can be chosen 1 way.

4×3×2×1=24

24 odd numbers with one's digit being 1 that are 5 digits long only using 1,2,3,4, and 5 with no repeats.

That means there are 24 odd numbers with one's digit being 3 that are 5 digits long only using 1,2,3,4, and 5 with no repeats.

Also means there are 24 odd numbers with one's digit being 5 that are 5 digits long only using 1,2,3,4, and 5 with no repeats.

3(24)=72

The population is the entire group of individuals that the neighborhood association wants to gather information about, in this case, the residents of the neighborhood.

The officers of a neighborhood association are interested in knowing if residents are willing to contribute towards beautifying the neighborhood and how much money they are willing to contribute. The officers are considering two methods for gathering data: Method A involves calling and surveying every tenth resident on the association's roster, while Method B involves randomly selecting and surveying 10 residents from among those who attend the neighborhood block party.

To properly design a survey, it is important to identify the population, which in this case is the entire neighborhood or community being served by the association. Identifying the population is necessary to ensure that the sample selected is representative of the population and can provide reliable results. The officers should also consider the potential biases associated with each sampling method and determine which one is more appropriate for their specific needs.

To solve this problem, we need to use the concepts of orbital mechanics and gravitational potential energy.

Part A

The velocity of the satellite in the inner circular orbit is given by the equation:

v = sqrt(GM/r)

where G is the gravitational constant, M is the mass of the earth, and r is the radius of the orbit. Substituting the given values, we get:

v = sqrt(6.674 x 10^-11 N*m^2/kg^2 * 5.97 x 10^24 kg / (260 x 10^3 m))

v = 7760 m/s

Part B

The velocity of the satellite at the low point of the elliptical orbit can be found using the equation:

v = sqrt(2GM/r1 - 2GM/r2)

where r1 and r2 are the radii of the inner and outer circular orbits, respectively. Substituting the given values, we get:

v = sqrt(2 * 6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (260 x 10^3 m) - 2 * 6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (35,900 x 10^3 m))

v = 1.004 x 10^4 m/s

Part C

The work done by the rocket motor to transfer the satellite from the circular orbit to the elliptical orbit is given by the difference in gravitational potential energy between the two orbits. This can be calculated using the equation:

W = mgh = m * G * M/r

where m is the mass of the satellite, g is the acceleration due to gravity, h is the height of the orbit above the earth's surface, and r is the radius of the orbit. Substituting the given values, we get:

W = 1000 kg * 6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (260 x 10^3 m) - 1000 kg * 6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (35,900 x 10^3 m)

W = 3.80 x 10^9 J

Part D

The velocity of the satellite at the high point of the elliptical orbit can be found using the equation:

v = sqrt(GM/r1 + GM/r2)

Substituting the given values, we get:

v = sqrt(6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (260 x 10^3 m) + 6.674 x 10^-11 Nm^2/kg^2 * 5.97 x 10^24 kg / (35,900 x 10^3 m))

v = 2.24 x 10^4 m/s

Part E

The velocity of the satellite in the outer circular orbit can be found using the equation in Part A, with the radius of the orbit set to 35,900 km. This gives:

v = sqrt(6.674 x 10^-11 N*m^2/kg^2 * 5.97 x 10^24 kg / (35,900 x 10^3 m)) v = 2.74 x 10^3 m/s

The new function after applying the sequence of transformation include: B. 1/2f(x + 5) - 11

In Mathematics and Geometry, the translation of a graph to the left means a digit would be added to the numerical value on the x-coordinate of the pre-image:

g(x) = f(x + N)

Conversely, the translation of a graph downward means a digit would be subtracted from the numerical value on the y-coordinate (y-axis) of the pre-image:

g(x) = f(x) - N

Since the parent function f(x) was translated 11 units downward, 5 units to the left, and vertically compressed (making it wider) by a factor of 1/2, the equation of the image g(x), we have:

The recursive formula that represents the same sequence of numbers as the explicit formula an = 3n + 4 is an = an-1 + 3, with the initial term a1 = 7.

A recursive formula defines a sequence by expressing each term in terms of previous terms. In this case, the explicit formula an = 3n + 4 gives us a direct expression for each term in the sequence.

To find the corresponding recursive formula, we need to express each term in terms of the previous term(s). In this sequence, each term is obtained by adding 3 to the previous term. Therefore, the recursive formula is an = an-1 + 3.

To complete the recursive formula, we also need to specify the initial term, a1. We can find the value of a1 by substituting n = 1 into the explicit formula:

a1 = 3(1) + 4 = 7

Hence, the complete recursive formula for the sequence is an = an-1 + 3, with the initial term a1 = 7. This recursive formula will generate the same sequence of numbers as the given explicit formula.

We can conclude that the triangles are similar, based on the Side-Angel-Side Theorem (SAS).

Hence, the answer is The third option.

Given the triangles EFG and BCD, you can identify that:

By definition, two triangles are similar if the lengths of the corresponding sides are in proportion and their corresponding angles are congruent.

In this case, you can identify that you know two pairs of corresponding sides. Then, you can find that they are in proportion. Set up that:

\(\frac{EF}{BC}=\frac{FG}{CD}\)

Substituting values and simplifying, you get:

\(\frac{18}{90}=\frac{16}{80}\\\\\frac{1}{5}=\frac{1}{5}\)

Notice that they are in proportion.

You can also identify that the corresponding angles F and I are congruent because they have equal measures.

Therefore, since you know that two sides are proportionate and the included angles are congruent, you can conclude that the triangles are similar, based on the Side-Angel-Side Theorem (SAS).

The amount of milk used per minute in a commercial kitchen that uses 3/4 of a cup of milk every 4/6 of a minute is 1/2 cup of milk.

In a recipe or cooking, fractions are frequently used. We can use them to measure ingredients such as sugar, butter, milk, and other items. The numerator of the fraction refers to the number of parts that are utilized. The denominator, on the other hand, refers to the whole.

The fraction 3/4 can be defined in the following ways: 3 parts out of 4 parts,75 parts out of 100 parts,15 parts out of 20 parts,The fraction 4/6 can be reduced as:4/6 = (4 ÷ 2)/(6 ÷ 2) = 2/3Thus, the fraction 4/6 represents 2/3 or two parts out of three parts.

We can use proportions to figure out how many cups of milk are used per minute. To do that, we need to convert the given quantity of milk into a fraction that represents the amount of milk used per minute

The kitchen uses 3/4 of a cup of milk every 4/6 of a minute.=> The fraction that represents the amount of milk used per minute = [3/4 ÷ 4/6]=> Multiplying the numerator and denominator of the above fraction by 6, we get:[3/4 ÷ 4/6] = [3/4 × 6 ÷ 4/6 × 6] = [18/24 ÷ 24/24] = 18/24= 3/4 (Reduced Form)Therefore, 3/4 of a cup of milk is used per 4/6 of a minute, or 1/2 cup of milk per minute, if we simplify it further.

In circle centered on (0,0) and a right triangle with one vertex at the origin of the circle  and the hypotenuse as a radius of the circle. By using Pythagorean theorem, the length of leg a is 4 units, and the length of leg b is 3 units. We can label corner A as (4,0) and corner C as (0,3).

Consider a circle centered at M (0,0) with a radius of 5 units. Let the hypotenuse of the right triangle be a radius of the circle. Let's say this hypotenuse is 5 units. Then, using the Pythagorean theorem, we can find the length of the other two sides:

a^2 + b^2 = c^2

where c is the hypotenuse (5 units), and a and b are the other two sides we want to find.

Let's say we want to label the corner of the triangle opposite to the hypotenuse as C, and the corners adjacent to the legs as A and B. Then we can set up the following:

Leg a runs from the origin (0,0) to corner A.

Leg b runs from corner A to corner C.

Hypotenuse c runs from the origin (0,0) to corner C.

Using the Pythagorean theorem, we can find the length of leg a as:

a^2 = c^2 - b^2

a^2 = 5^2 - b^2

a^2 = 25 - b^2

Assuming b = 3, we can find the length of leg a as:

a^2 = 25 - 3^2

a^2 = 16

a = 4

So, the length of leg a is 4 units, and the length of leg b is 3 units. We can label corner A as (4,0) and corner C as (0,3).

The range in which 95% of the scores lie is between 75 and 95.

According to the Empirical Rule: For a normal distribution, approximately 68% of the data falls within 1 standard deviation of the mean, approximately 95% of the data falls within 2 standard deviations of the mean, and approximately 99.7% of the data falls within 3 standard deviations of the mean.

So, about 95% of the scores lie between 75 and 95. T

This is because the mean score is 85 and one standard deviation is 5, so one standard deviation below the mean is 80 (85-5) and one standard deviation above the mean is 90 (85+5).

Two standard deviations below the mean are 75 (85-2*5) and two standard deviations above the mean is 95 (85+2*5).

Therefore, the range in which 95% of the scores lie is between 75 and 95.
