The domain is all points (x, y) satisfying the inequality 4x² + 4y² < ∞. The domain of the function f(x, y) = e^(-(4x² + 4y²)) consists of all points (x, y) in the xy-plane where 4x² + 4y² is finite.
The domain of a function represents the set of all valid input values for the function. In this case, the function f(x, y) is defined as the exponential of -(4x² + 4y²). For the exponential function to be defined, the exponent must be a real number.
In the given function, the exponent -(4x² + 4y²) involves the sum of squares of x and y multiplied by 4. Since squares are always non-negative, 4x² and 4y² are both non-negative. As a result, the sum 4x² + 4y² is also non-negative. Therefore, for the exponent to be defined, 4x² + 4y² must be a finite value.To express this condition mathematically, we can say that 4x² + 4y² is less than infinity (∞). This indicates that the domain includes all points (x, y) for which 4x² + 4y² is finite. In other words, the function is defined for all points in the xy-plane, as long as the sum of the squares of x and y remains finite. Hence, the correct choice for the domain is (B) "The domain is the entire xy-plane.

1. there are 15 boys and 17 girls in a math class. what is the ratio of boys to girls? (6.rp.1) * 15:17 15:32 17:15 32:15
If there are 15 boys and 17 girls in a math class then, the ratio of boys to girls is Option A. 15:17
The ratio of boys to girls in the math class is 15:17. This can be found by dividing the number of boys by the number of girls, which gives:
15/17
This ratio cannot be simplified because 15 and 17 do not have any common factors other than 1. Therefore, the ratio of boys to girls is 15:17.
The ratio of boys to girls in a math class is the relationship between the number of boys and the number of girls. The ratio is a way of expressing the comparison between two quantities. In this case, there are 15 boys and 17 girls in the class. To find the ratio of boys to girls, we divide the number of boys by the number of girls, which gives 15/17. This ratio cannot be simplified further because 15 and 17 do not have any common factors other than 1. Therefore, the ratio of boys to girls in the math class is 15:17. This means that for every 15 boys in the class, there are 17 girls.

If a baby has a fever, then the baby is sick. If a baby is sick, then the baby must
be brought to the hospital.
By using the Law of Syllogism, a conditional should be used to write this statement "If a baby has a fever, then the baby is sick. If a baby is sick, then the baby must be brought to the hospital" as follows: B. If the baby has a fever, then the baby must be brought to the hospital.
What is the Law of Syllogism?In Mathematics, the Law of Syllogism is sometimes referred to as reasoning by transitivity and it states that if two (2) statements are true, then a third true statement can be logically derived.
Mathematically, the Law of Syllogism follows a specific pattern and can be represented by the following conditional statements:
Conditional statement 1: If P, then Q (P ↔ Q).
Conditional statement 2: If Q, then R (Q ↔ R.
Conditional statement 3: If P, then R ( P ↔ R).
In this context, we can reasonably infer and logically deduce that a sick baby must be taken to hospital based on the given premise in accordance with the Law of Syllogism.

one half times the quantity y minus 20 equals two thirds
one half times the quantity 20 minus y equals two thirds
one half times y minus 20 equals two thirds
one half times 20 minus y equals two thirds
Answer:
One half times the difference of twenty and a variable is two thirds
one half times the quantity y minus 20 equals two thirds
one half times the quantity 20 minus y equals two thirds
one half times y minus 20 equals two thirds
one half times 20 minus y equals two thirds
0.5(20 - y) = 2/3
One half times the difference of twenty and a variable is two thirds :
1/2(20 - y) = 2/3
[this one im not too sure, please confirm it cause i don't think it is clear enough]
One half times the quantity y minus 20 equals two thirds :
1/2(y - 20) = 2/3
One half times the quantity 20 minus y equals two thirds :
1/2(20 - y) = 2/3
One half times y minus 20 equals two thirds :
1/2 x y - 20 = 2/3
One half times 20 minus y equals two thirds :
1/2 x 20 - y = 2/3
A population of pheasants is declining over time. The number of adults per hectare has decreased from 1,832 in 2012 to 422 in 2016. In which year will the population fall below the minimum viable density, 100 pheasants per hectare?
The number of pheasants in 2012 was 1832. The number of pheasants in 2016 was 422. The minimum viable density is 100 pheasants per hectare.
So, we need to find out the year in which the population will fall below 100 pheasants per hectare.
First, we need to find out the rate of decline per year which can be calculated as follows: Rate of decline per year = (1832 - 422) / (2016 - 2012)= 1410 / 4= 352.5 per yearNow, let the number of pheasants per hectare be y after t years from 2012.
Then, y = 1832 - 352.5t (as we know the rate of decline per year)We need to find the year in which the population will fall below 100 pheasants per hectare. So, we need to solve the equation:1832 - 352.5t = 100⇒ 352.5t = 1732⇒ t = 1732 / 352.5⇒ t = 4.91 Therefore, the population will fall below the minimum viable density of 100 pheasants per hectare after 4.91 years from 2012, which is around 2017 or 2018.

tickets are directly proportional to number of hours.
t =kh
we find K.
240 = 3k
we divide by 3 in both sides.
k = 80
we substitute K to find how many tickets.
t =80 × 8

the taxi and takeoff time for commercial jets is a random variable x with a mean of 8.3 minutes and a standard deviation of 2.3 minutes. assume that the distribution of taxi and takeoff times is approximately normal. you may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway.
The probability comes out to be 0.2296
We need to calculate the probability of each jet waiting at least 10 minutes before takeoff.
P(X≥10)=?
Let Z be the standard normal variable.
Z=(X-μ)/σ
Where μ is the mean of the taxi and take-off time for commercial jets and σ is the standard deviation of the taxi and takeoff time for commercial jets.
Z=(X-8.3)/2.3
Using the z-score formula, Z=(X-μ)/σ, we can standardize the value of the variable X to get its respective z-score value, z.
With a mean of 8.3 and a standard deviation of 2.3, the standardized score for a taxi and takeoff time of 10 is:
z=(10-8.3)/2.3 = 0.73913
The probability of a jet waiting at least 10 minutes before takeoff can be calculated as follows:
P(X≥10) = P(Z≥0.73913)
The probability of a standard normal random variable z is greater than or equal to 0.73913 is:
1 - Φ(0.73913)
where Φ(z) is the standard normal distribution function.
Using a standard normal distribution table or calculator, we find that:
Φ(0.73913) = 0.7704
Therefore: P(X≥10) = P(Z≥0.73913)= 1 - Φ(0.73913)= 1 - 0.7704= 0.2296
Thus, the probability of each jet waiting at least 10 minutes before takeoff is 0.2296.

what is a simpler form of the radical expression ^4 sqrt 2401x^12y^16
Step-by-step explanation:
To simplify the given radical expression, we can first break down 2401 into its prime factors, which gives us:
2401 = 7^4
We can then simplify the given expression as follows:
^4 sqrt (2401x^12y^16) = ^4 sqrt (7^4 * x^12 * y^16)
= ^4 sqrt (7^4) * ^4 sqrt (x^12) * ^4 sqrt (y^16)
= 7 * x^3 * y^4
Therefore, the simplified form of the given expression is 7x^3y^4.

sea l la longitud de la escalera = 2.5 m
La distancia desde la base de la escalera hasta la pared (d) = 0.7 m
Sea h la distancia desde la parte inferior de la pared hasta la parte superior de la escalera.

h² = 2.5² - 0.7²
h² = 5.76
h = 0.24 m
La escalera se desliza verticalmente hacia abajo 0,3 m, por lo tanto, h'= 2.4 m - 0.3 m = 2.1 m
La distancia desde la parte inferior de la escalera hasta la pared (d ') se obtiene usando el teorema de Pitágoras:

Consider the exponential function f(x) = 57(0.48)What is the 2-unit growth factor for f ? What is the 1-unit growth factor for f ? What is the initial value of f ? f
The 2-unit growth factor for f is 0.2304.
The 1-unit growth factor for f is 0.48.
The initial value of f is 57.
Given an exponential function f(x) = 57(0.48).
Formula for the exponential function is:
f(x) = a*b*x
Here, a= initial value, b = growth factor, x = variable.
The growth factor b can be calculated as 0.48.
In order to calculate the 2-unit growth factor, substitute (x + 2) in the given function. So the function becomes:
f(x+2) = 57(0.48)2
Now the growth factor is calculated using the formula, f(x+2)/f(x).
So the 2-unit growth factor is = 0.48^2 = 0.2304.
Now in order to calculate the 1-unit growth factor, substitute (x + 1) in the given function.
So the function becomes f(x+1) = 57(0.48)
Now the growth factor is calculated using the formula, f(x+1)/f(x).
So the 1-unit growth factor = 0.48.
From the given function, initial value a is 57. Hence the initial value of f is 57.
Therefore, the initial value of f is 57, the growth factors for 2-unit and 1-unit increases are 0.2304 and 0.48 respectively.

12 x 10= 120 miles
Answer:
Definitely 120 miles per hour.
