A jet airplane begins a steady climb of 15° and flies for two miles (measured horizontally). What is the change in altitude in feet? Round your answer to the nearest hundredth of a foot.
Answer:
Rounding to the nearest hundredth of a foot, the change in altitude is approximately 514.77 feet.
Step-by-step explanation:
To solve this problem, we can use trigonometry. The angle of climb is 15 degrees, which means that the ratio of the change in altitude to the horizontal distance traveled is the tangent of 15 degrees:
tan(15°) = change in altitude / horizontal distance
We can rearrange this equation to solve for the change in altitude:
change in altitude = horizontal distance x tan(15°)
Substituting the given values, we get:
change in altitude = 2 miles x tan(15°)
We can convert the distance to feet by multiplying by 5280:
change in altitude = 2 miles x 5280 feet/mile x tan(15°)
Using a calculator, we get:
change in altitude ≈ 514.77 feet
Rounding to the nearest hundredth of a foot, the change in altitude is approximately 514.77 feet.

a) The speed at which the car gets maximum gas mileage is given as follows: 48 miles per hour.
b) The max gas mileage is given as follows: 29.5 miles per gallon.
How to obtain the maximum gas mileage?The gas mileage is modeled as a function of the velocity x according to the quadratic function presented as follows:
m(x) = -0.028x² + 2.688x - 35.012.
The coefficients are given as follows:
a = -0.028, b = 2.688, c = -35.012.
The leading coefficient a is negative, hence the vertex represents the point at which the maximum mileage is obtained.
The velocity is given as follows:
x = -b/2a
x = -2.688/[2(-0.028)]
x = 48 miles per hour.
The max gas mileage is obtained as follows:
m(48) = -0.028(48)² + 2.688(48) - 35.012.
m(48) = 29.5 miles per gallon.

Company XYZ closed at $53.21 per share with a P/E ratio of 13.26 . Answer the following questions. a. How much were earnings per share? b. Does the stock seem overpriced, How much were earnings per share? b. Does the stock seem overpriced, underpriced, or about right given that the historical P/E ratio is 12-14?ced, or about right given that the historical P/E ratio is 12-14?
Answer: a. To find the earnings per share (EPS), we can use the formula:
P/E ratio = Price per share / Earnings per share
Rearranging this formula to solve for EPS, we get:
Earnings per share = Price per share / P/E ratio
Substituting the given values, we have:
Earnings per share = $53.21/13.26 ≈ $4.01
Therefore, the earnings per share were approximately $4.01.
b. To determine if the stock is overpriced, underpriced, or about right given the historical P/E ratio of 12-14, we can compare the current P/E ratio to this range. Since the current P/E ratio is 13.26, which falls within the historical range, the stock seems to be about right in terms of valuation. However, it's important to note that other factors should also be considered before making any investment decisions.

In a race, 24 out of the 25 bicyclists finished in less than 56 minutes. What percent of bicyclists finished the race in less than 56 minutes? Write an equivalent fraction to find the percent.
The percentage of bicyclists that finished the race in less than 56 minutes is 96 %
What is percentage?Percentage is a ratio out of hundred
If in a race, 24 out of the 25 bicyclists finished in less than 56 minutes. To find what percent of bicyclists finished the race in less than 56 minutes, we first write it in a fraction as number/total
Since
number = 24 and total = 25We have that
fraction = number/total
= 24/25
Now to write it as a percentage, we multiply by 100.
So, we have that percentage = fraction × 100 %
So, we have that in percentage = 24/25 × 100 %
= 24 × 4 %
= 96 %
So, the percentage is 96 %

Describe Ordered Pair?In mathematics, an ordered pair is a collection of two objects, which are arranged in a specific order. The order of the objects in the pair is important, as the ordered pair (a, b) is different from the ordered pair (b, a) if a and b are not equal.
The two objects in an ordered pair can be anything, such as numbers, variables, or other mathematical entities. The ordered pair (x, y), for example, can represent a point on a two-dimensional coordinate plane, where x represents the horizontal coordinate and y represents the vertical coordinate.
The ordered pair notation is commonly used in set theory and other branches of mathematics to represent relationships between two objects. Ordered pairs can also be used to define functions, where the first object in the pair represents an input to the function, and the second object represents the output.
Here's the completed table and ordered pairs:
Cost of plain rings (x) Cost of initial rings (y) (Ordered Pairs (x,y))

Answer:
Step-by-step explanation:
Use SAS congruency; AD=DC, and they both share side BD. Also, BD is the perpendicular bisector to AC, so it also forms 2 right angles. Proof using SAS.
Or, if you don’t know SAS congruency, you may use SSS congruency;
Use the Pythagorean theorem. Side length AB^2 = AD^2 + BD^2
BC^2 = DC^2 + BD^2.
AD=DC, so therefore AB = BC. Use SSS congruency, and there you go.
You have realised that instead of reducing your car's short-term insurance ium as its book value decreases, your insurer has actually increased the premium % per year "to keep up with inflation". If your premium started off at R450 per month. have you paid in total after 2 years?
To calculate the total amount paid over two years, we first need to determine the annual premium increase percentage. Let's assume the insurer increases the premium by 5% per year to keep up with inflation.
After the first year, the new premium would be:
R450 + (5% of R450) = R472.50 per month
After the second year, the new premium would be:
R472.50 + (5% of R472.50) = R496.13 per month
To calculate the total amount paid over two years, we can use the following formula:
Total amount paid = (monthly premium x 12 months x number of years)
= (R450 x 12 x 2) + (R472.50 x 12 x 1) + (R496.13 x 12 x 1)
= R10,800 + R5,670 + R5,953.56
= R22,423.56
Therefore, you would have paid a total of R22,423.56 over two years.

A = P(1 + r/n)^(nt)
Where:
A is the account balance after a certain amount of time
P is the principal or initial amount invested
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year

Answer:
approx 20% of the department faculty have 20 or more years of service
Step-by-step explanation:
To find the percentage of the department faculty with 20 or more years of service, we need to add up the number of faculty members in the "20-24.9" and "25 or more" year categories, since anyone with 20 or more years of service would fall into one of these categories.
Looking at the histogram, we see that there are 24 faculty members in the "20-24.9" year category, and an additional 4 in the "25 or more" year category. Therefore, the total number of faculty members with 20 or more years of service is 24 + 4 = 28.
To calculate the percentage of faculty members with 20 or more years of service, we need to divide this number by the total number of faculty members in the department, which we can find by adding up the heights of all the bars in the histogram. Based on the heights of the bars in the histogram, we can estimate that the total number of faculty members is approximately 140.
Therefore, the percentage of faculty members with 20 or more years of service is:
(28/140) x 100% = 20%
So, approximately 20% of the department faculty have 20 or more years of service.
