The maximum distance D(h) in kilometers that a person can see from a height h kilometers above the ground is given by the function D(h)=111.7 times square root of h. Find the height that would allow a person to see 50 kilometers.
To find the height that allows a person to see 50 kilometers, we set the given function equal to 50 and solve for h. This calculation gives us the height as approximately 0.2 kilometers.
Explanation:The question requires us to find the height h that would allow a person to see 50 kilometers, given the function D(h)=111.7 * sqrt(h).
We can solve this by setting the function equal to 50 and then solving for h. Like so: 50 = 111.7 * sqrt(h).
To isolate sqrt(h), we divide both sides of the equation by 111.7: sqrt(h) = 50 / 111.7.
Then we square both sides of the equation to solve for h: h = (50 / 111.7)^2.
Upon calculating the right side of this equation, we find that the height is approximately 0.2 kilometers.

The answer for this question is 0.2 Kilometers or 200 meters(approx.)
The detailed explanation is as follows :
The maximum distance D(h) in kilometers that a person can see from a height h kilometers above the ground is given by the function D(h)=111.7 times square root of h. We need to find the height that would allow a person to see 50 kilometers.
To solve this problem, we need to find the height h that allows a person to see a distance of 50 kilometers. We start with the given function:
D(h) = 111.7 * sqrt(h)
We set D(h) to 50 kilometers:
50 = 111.7 * sqrt(h)
To isolate sqrt(h), we divide both sides by 111.7:
sqrt(h) = 50 / 111.7
Next, we calculate the division:
sqrt(h) ≈ 0.4475
Now we square both sides to find h:
h = (0.4475)^2 ≈ 0.2002
Therefore, the height that allows a person to see 50 kilometers is approximately 0.2002 kilometers, or 200.2 meters above the ground.
Hence the required answer is 0.2 kilometers or 200 meters(approximately)

How many window coverings are necessary to span 50 windows if each window covering is 15 windows long?
To find out how many 15-window coverings are needed for 50 windows, divide 50 by 15, which gives approximately 3.33. Rounding up because we can't have partial window coverings, we will need 4 coverings.
Explanation:The question asks: How many window coverings are necessary to span 50 windows if each window covering is 15 windows long?
To answer this question, we can do a simple division. We divide the total number of windows (50) by the length of each window covering (15).
So, we have 50 ÷ 15 which equals approximately 3.33. However, since we cannot have a fraction of a window covering, we need to round this number up. Therefore, we would need 4 window coverings to span 50 windows.

Final answer:
To find the number of different ways a new car can be ordered with various options, multiply the number of choices for each option.
Explanation:
To find the number of different ways a new car can be ordered with regard to the given options, we need to multiply the number of choices for each option. There are 10 possible colors, 2 choices for air conditioning (with or without), 2 choices for automatic transmission, 2 choices for power windows (with or without), and 2 choices for a CD player (with or without).
Therefore, the total number of different ways a new car can be ordered is:
10 colors × 2 choices for air conditioning × 2 choices for automatic transmission × 2 choices for power windows × 2 choices for a CD player = 10 × 2 × 2 × 2 × 2 = 160
Which statement is true for the set of natural numbers?
A. The set is closed under addition and closed under subtraction
B. The set is closed under addition and not closed under subtraction
C. The set is not closed under addition and closed under subtraction
D. The set is not closed under addition and not closed under subtraction
The set of natural numbers is closed under addition but not under subtraction.
Explanation:The statement that is true for the set of natural numbers is B. The set is closed under addition and not closed under subtraction.
In mathematics, a set is considered closed under an operation if applying that operation to any two elements in the set always produces an element that is also in the set.
For the set of natural numbers, adding two natural numbers will always result in another natural number, so it is closed under addition. However, subtracting two natural numbers may result in a negative number, which is not a natural number, so it is not closed under subtraction.

Find the dimensions of a box with a square base with
(a) volume 12 and the minimal surface area
(b) surface area 20 and minimal volume ...?
The dimensions of the box for minimal surface area when volume is 12 are both the cube root of 3. When surface area is 20 for minimal volume, the dimensions are sqrt(5) for the base and (15 / (4*sqrt(5))) for the height.
Explanation:The concept in this problem is about minimizing surface area and volume with relation to the dimensions of a box.
Let's consider a box with a square base of side 'x' and height 'h'. For part (a), the volume V of a box is given by V = x^2 * h which implies h = V / (x^2).
Substituting V = 12, we get h = 12/x^2. The surface area S of a box is given by S = x^2 + 4xh.
Substituting the value of h in the surface area equation, we have S = x^2 + 48/x.
To find the minimum surface area, we differentiate the above with respect to 'x' and set it equal to 0, which gives the dimensions of the box to be x = h = cube root of 3.
For part (b), the surface area S is given to be 20. So, S = x^2 + 4xh implies 4xh = 20 - x^2. The volume of the box is V = x^2 * h = (20 - x^2) / 4.
To minimize the volume, we differentiate V with respect to 'x' and set it to 0. That gives us the value of 'x' to be sqrt(5), and 'h' to be (20 - 5) / (4*sqrt(5))

Numbers 1 - 10 are written on cards and placed in a bag. Find the probability of choosing a number greater than 5 or choosing an odd number. ...?
The probability of selecting a card greater than 5 or an odd number from a bag of cards numbered 1 to 10 is 0.8 or 80%.
Explanation:The question asks for the probability of choosing a number greater than 5 or an odd number from a bag containing numbered cards from 1 to 10. To solve this, we should consider that numbers greater than 5 are 6, 7, 8, 9, and 10. There are 5 odd numbers in the set: 1, 3, 5, 7, and 9. The number 7 and 9 are both greater than 5 and odd, so they are counted only once when combining the two groups.
First, let's count the total unique outcomes that either meet the criterion of being greater than 5 or being odd: 6, 7, 8, 9, 10, 1, 3, 5 (7 and 9 are already counted). There are 8 such numbers.
The total number of possible outcomes is 10, as there are 10 cards. The probability is the number of favorable outcomes divided by the total number of possible outcomes: P = favorable outcomes / total outcomes = 8/10 = 0.8 or 80%.
Tickets for a school play cost $7 and $10 for the adults. The equation 7x+10y=80 represents the number of students(x) and the number of adults(y) who can attend the play for $80. If no students attend, how many adults can see the play for $80?
If no students attend the play, then 8 adults can see the play for $80.
Explanation:The subject of this question is Mathematics, specifically linear equations. The scenario presented involves ticket sales for a school play with different ticket prices for students and adults. $7 is the price for a student ticket and $10 is for an adult ticket. The given equation 7x+10y=80 represents the total sum of $80 that needs to be reached with a combination of student tickets (x) and adult tickets (y).
If no students attend, x in the equation is 0, so we have 10y = 80. To find the number of adults (y) that can attend the play for $80, we need to solve this equation for y. So, y = 80 / 10. Therefore, y = 8, meaning 8 adults can attend the play for $80 when no students attend.

The Florida tourism board surveyed people on their favorite vacation cities. Half of the people said Orlando, 1/4 said Miami, 1/8 said Kissimmee, 1/16 said Fort Lauderdale, 1/32 said Key West, and the rest said Tampa. If 22 people said Tampa, how many people responded Orlando?
To find out how many people responded Orlando, we need to add up the fractions for Miami, Kissimmee, Fort Lauderdale, Key West, and Tampa and then set up a proportion to find the number of people who said Orlando. The answer is approximately 47 people.
Explanation:To find out how many people responded Orlando, we need to add up the fractions for Miami, Kissimmee, Fort Lauderdale, Key West, and Tampa since the rest said Tampa. The fractions we need to add are 1/4, 1/8, 1/16, and 1/32. Let's calculate each fraction to get a common denominator.
1/4 = 8/32, 1/8 = 4/32, 1/16 = 2/32, 1/32 = 1/32.
Now we can add them up: 8/32 + 4/32 + 2/32 + 1/32 = 15/32.
Since the remaining fraction is Tampa, which corresponds to 22 people, we can set up a proportion: 15/32 = 22/x to find out how many people said Orlando. Cross-multiply and solve for x: 32 * 22 = 15x, 704 = 15x, x = 704/15, x ≈ 46.93.
Therefore, approximately 47 people responded Orlando.

Step-by-step explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32 ft/s²
[tex]s=ut+\frac{1}{2}at^2\\\Rightarrow h=ut+\frac{1}{2}32\times t^2\\\Rightarrow h=ut+16t^2[/tex]
Here, u = 0 so,
[tex]h=0t+16t^2\\\Rightarrow h=16t^2[/tex]
The equation is [tex]h=16t^2[/tex]

Which of the following at the three cs of credit
The three Cs of credit are character, capacity, and capital, which represent the creditworthiness of an individual or business as assessed by lenders based on reputation, ability to repay, and assets for collateral respectively.
Explanation:The three Cs of credit refer to character, capacity, and capital. These are the main criteria that lenders consider when assessing the creditworthiness of an individual or business. Character refers to the borrower's reputation and track record for repaying debts. Capacity is the borrower's ability to repay the loan, determined by their income and existing debt levels. And capital relates to the wealth or assets the borrower can offer as collateral. When banks conduct credit checks or require a co-signer, they are evaluating these aspects to decide on lending money.
