The airplane has traveled a ground distance of 2900 ft when it has attained an altitude of 2400 ft at an angle of 40 degrees with the ground.
Determine ground distanceThe ground distance that the airplane has traveled can be found using the trigonometric function of tangent. The tangent of an angle is the ratio of the opposite side to the adjacent side in a right triangle. In this case, the opposite side is the altitude (2400 ft) and the adjacent side is the ground distance we are trying to find.
We can use the formula:
tan(angle) = opposite/adjacent
Plugging in the given values:
tan(40) = 2400/adjacent
Solving for the adjacent side (ground distance):
adjacent = 2400/tan(40)
Using a calculator, we can find the value of tan(40) and then divide 2400 by that value to get the ground distance:
adjacent = 2400/0.8391
adjacent = 2860.67 ft
Rounding to the nearest 100 ft, the ground distance is 2900 ft.
Therefore, the airplane has traveled a ground distance of 2900 ft when it has attained an altitude of 2400 ft at an angle of 40 degrees with the ground.

d of a transverse wave is 25 m/s, if the source produces a disturbance that has a frequency of 200 Hz, what is the wavelength of the wave?
The wavelength will be "0.125 m".
What are Frequency and Wavelength?The wavelength, as well as frequency, have an inverse relationship. It shows that whenever a short wavelength exists, a high frequency exists, and when a big wavelength exists, a lower frequency exists.
The distance of a single wave-particle travels after completing one oscillation would be its wavelength.
According to the given information,
Speed of transverse, s = 25 m/s

big augie's pizza now offers triangle shaped pizzas. how long must the sides fo the pizza be to the nearest inch equal the size of a round pizza with a 17 inch diameter?
Answer:
Step-by-step explanation:
The area of a round pizza with a 17 inch diameter is:
A = πr^2 = π(8.5)^2 ≈ 226.98 square inches
To find the length of the sides of a triangle with the same area, we can use the formula for the area of a triangle:
A = (1/2)bh
where b is the base of the triangle and h is the height.
Since the triangle is equilateral (i.e., all sides are equal), the base and height are the same. Let's call this length x. Then:
A = (1/2)bh = (1/2)x(x/2) = x^2/4
Setting this equal to the area of the round pizza, we get:
x^2/4 = 226.98
Multiplying both sides by 4, we get:
x^2 = 907.92
Taking the square root of both sides, we get:
x ≈ 30.13
So the sides of the equilateral triangle should be about 30.13 inches long to have the same area as a round pizza with a 17 inch diameter. Rounded to the nearest inch, the sides of the triangle should be 30 inches long.

The money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.
What is simple interest?
In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed). It is not the same as a fee that the borrower might pay to the lender or another entity.
Borrowers must pay lenders simple interest as a fee in exchange for a loan. For simple interest calculation, compounding interest is excluded from the calculation and just the original principal is used. Simple interest applies to all loans, not just specific ones. Additionally, it refers to the kind of interest that banks give their customers on their savings accounts.
Given,
Time period = 2 years
Rate of interest = 8%
The simple interest paid at the end of 2 years = $ 1120
The money borrowed or the principal amount is
Simple interest = (Principal amount * rate * time)
1120 = P * 0.08 * 2
P = 1120/0.16 = $7000
Therefore the money borrowed by Alonzo at a simple interest rate of 8% for a time period of 2 years is $7000.

c) Answer the question.
a) This situation represents exponential growth, as the number of bacterial cells is doubling every hour.
b) Let N be the number of bacterial cells on the petri dish at time t in hours. The equation to model the situation is:
N = 30 x 2^t
This equation represents exponential growth, as the number of bacterial cells is doubling every hour. The initial number of bacterial cells is 30 (when t = 0), and the number of bacterial cells at any time t is given by multiplying the initial number by 2 raised to the power of t.
c) After 5 hours, the number of bacterial cells on the petri dish is:
N = 30 x 2⁵ = 30 x 32 = 960
So there are 960 bacterial cells on the petri dish after 5 hours.

which terms are used to describe events that have no outcomes in common?
The term used to describe events that have no outcomes in common is called "Mutually Exclusive."
Probability is a measure of how likely an event is to occur. The probability of an event ranges from 0 to 1, where 0 means that an event will not occur, and 1 means that an event will certainly occur.
In Mutually Exclusive events, the probability of both events happening at the same time is 0, which means that the outcome of one event completely eliminates the possibility of the outcome of the other event. The probability of getting heads and tails at the same time is 0, as it is impossible for the coin to show both heads and tails at the same time.
In mathematical terms, Mutually Exclusive events are represented by
=> P(A) + P(B) = P(A or B),
where P(A) represents the probability of event A, P(B) represents the probability of event B, and P(A or B) represents the probability of either event A or B occurring.
To summarize, Mutually Exclusive events are events that have no outcomes in common and have a probability of 0 of occurring simultaneously.

A linear function is demonstrated by the line a.
Line a has a slope of one.
Y = x + 2 is the equation for the line a.
How do you calculate a line's slope?
Following points on line a (x,y) = (0,2) and are available in the figure (2,4)
Calculating the slope (m) involves using:
m= y^2-y^1/x^2-x^1
This results
m= 4-2/2-0
Analyze m = 1
Consequently, the line's slope is 1.
The formula for line aThe formula for this is y = m(x - x1) + y1.
We thus have:
y = (x - 0) + 2
y = x + 2: Compare the difference and the result.
Consequently, y = x + 2 is the equation for the line a.
