What is floating-point literal?Numbers with a decimal point or an exponential component are known as floating-point literals. Real literals are one way to describe them. binary literals for floating points. Hexadecimal literals for floating points (C only). An exponent, a decimal point, a fractional part, and an integer part are all components of a floating-point literal. Either decimal form or exponential form can be used to express floating point literals. A floating point number is a full number that has a decimal point and can be positive or negative. In contrast to 91 and 0, floating point numbers include anything like 5, 0, 25, and -103.342. Because the decimal point can "float" to any required position, floating point numbers receive their name.Type 540,000,000 as a floating-point literal using scientific notation with a single digit before and after the decimal point is 5.4e8.

per day. Write an exponential model representing the amount of Iodine-125 remaining in the tumor after t
days. Then use the formula to find the amount of Iodine-125 that would remain in the tumor after 60
days.
Enter the exact answer.
Enclose arguments of functions in parentheses and include a multiplication sign between terms. For example, c*exp(h)
or c*ln(h)
.
Answer:
The exponential model representing the amount of Iodine-125 remaining in the tumor after t days would be:
Iodine-125(t) = 0.6 * e^(-0.0115t)
To find the amount of Iodine-125 that would remain in the tumor after 60 days, we would plug in t = 60 into the model:
Iodine-125(60) = 0.6 * e^(-0.0115(60))
= 0.6 * e^(-0.69)
= 0.6 * 0.5032
= 0.3019
So after 60 days, there would be approximately 0.3019 grams of Iodine-125 remaining in the tumor.

The proportional relationship between the number of inches a candle has burned away, b, at any time in hours, t, can be represented by the equation b = 1.5tb=1.5t. At what rate does the candle burn, in inches per hour?
The rate at which the candle burns is 1.5 inches per hour.
At what rate does the candle burn, in inches per hour?We know that the proportional relation between the number of inches that the candle has burned away, b, and the time in hours, t, is:
b = 1.5*t
The rate at which the candle burns is the amount burned in one unit of time, in this case, hours, then:
So, after t = 1 (one hour)

Using mathematical operations, Ara's remaining pounds of apples are 1.405 pounds.
What are mathematical operations?The four basic mathematical operations are addition, subtraction, division, and multiplication.
In this situation, we applied the mathematical operations of multiplication, addition, and subtraction to determine the difference (or the quantity of apples left) between the quantity brought to the market and the quantity sold.
The total quantity of apples = 35¹/₂ pounds
The quantity sold in the morning = ¹/₂ of 35¹/₂ pounds = 17.75 pounds
The quantity sold in the afternoon = ⁴/₁₉ of 35¹/₂ pounds = 7.47 pounds
The quantity sold in the evening = ¹/₄ of 35¹/₂ pounds = 8.875 pounds
The total quantity sold = (¹/₂ + ⁴/₁₉ + ¹/₄) = ³⁶/₃₈ of 35¹/₂ pounds = 34.095 pounds

Kevin hiked up Lamb's Canyon in 3 hr and then ran back down in 2 hr. His speed running downhill was 1.8 mph greater than his speed hiking uphill. How far up the canyon did he hike?
Kevin hiked (blank) mi up the canyon.
Kevin hiked up Lamb's Canyon with the goal of making it to the top.
How far up the canyon did he hike?To solve it, you need to set up two equations - one for hiking and one for running.Let x be the distance Kevin hiked up the canyon.
For hiking: 3 hr = x / h
For running: 2 hr = (x + 1.8) / r
Where h is the speed at which Kevin hiked uphill and r is the speed at which he ran downhill.Solving the two equations for x yields:
x = (3h * r) / (h + r)
To find the distance Kevin hiked up the canyon, you need to plug in the values for h and r.Therefore, Kevin hiked (3h * r) / (h + r) mi up the canyon.
For the distance that Kevin hiked uphill, the equation would look like this:Distance = (x mph) * (3 hr)
For the distance that Kevin ran downhill, the equation would look like this:Distance = (x + 1.8 mph) * (2 hr)
We can combine these two equations by setting them equal to each other and solving for x. We get:(x mph) * (3 hr) = (x + 1.8 mph) * (2 hr)
Solving for x, we get x = 2.4 mph.
Now that we know x, we can plug it back into our original equation for the distance that Kevin hiked uphill. We get:Distance = (2.4 mph) * (3 hr) = 7.2 mi. Therefore, Kevin hiked 7.2 mi up the canyon.To learn more about to find the distance refer to:

Given the following probabilities for choosing 2 marbles from a bag of 10 marbles are:-
P(blue) = 3/10, P(green) = 1/5, P(blue and green) = 3/100
We know the fact that two event are independents if we have following:-
P(X and Y) = P(X) times P(Y)
For this problem, we must have P(blue and green) = P(blue) times P(green).
P(blue and green) = (3/10) * (1/5) = 3/50
But given P(blue and green) = 3/100
Since we have 3/100 ≠ 3/50

The given triangle is obtuse triangle according to the corollary to the converse of the Pythagorean Theorem.
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The triangle's longest side measures 15 units in length.
Compare the sum of the squares on the other two sides to the square that is the length of the longest side.
The square of the longest side is 15², which equals 225.
9² + 10² = 181 square units make up the sum of the squares on the other two sides.
Thus, 181 < 15².
As a result, the triangle is an obtuse triangle according to the corollary to the converse of the Pythagorean Theorem.

The airplane will take 0.0095 seconds to cover 272 meters at a rate of 769 kilometers per hour, which is equivalent to 213.6 meters per second.
(272 m) / (769 km/h) x (1 h/3600 s) = 0.0095 s
1. Convert km/h to m/s: 769 km/h x (1000 m/1 km) x (1 h/3600 s) = 213.6 m/s
2. Divide the distance to travel (272 m) by the rate (213.6 m/s): 272 m / 213.6 m/s = 0.0095 s
The airplane's speed on this certain flight is 769 kilometers per hour. In order to calculate how long it will take to cover a distance of 272 meters, we must first convert the speed to meters per second. 769 kilometers per hour is equivalent to 213.6 meters per second. Once we have the rate, we can divide the distance by the rate, which is 272 meters divided by 213.6 meters per second. This calculation yields a result of 0.0095 seconds.
