Select all of the following true statements if R = real numbers, I = integers, and T = {..., -5, -4, -3, -2}.
Answers
All the correct statements are,
⇒ ∅ ⊂ R
⇒ {... , - 5, - 4, - 3, - 2} ⊆ T
⇒ T ⊂ I
⇒ 0 ∈ I
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We know that;
For ∅ ⊂ R;
A null set is a subset of R, and in fact every set in general. There are no elements in a null set thus making it automatically a subset of any non-empty set by definition.
Hence, We get;
⇒ ∅ ⊂ R
For 6 ∈ T;
Since T is the set of negative integers less than - 1.
Hence, 6 ∉ T
For {... , - 5, - 4, - 3, - 2} ⊆ T
The set on the left is exactly what is defined on the problem statement for T. (The bar below the subset symbol just means that the subset is not strict, therefore the set on the left can be equal to the set on the right. Without it, the statement would be false since a strict subset requires that the two sets should not be equal).
Hence, {... , - 5, - 4, - 3, - 2} ⊆ T
For T ⊂ I;
Clearly, T is the set of negative integers less than - 1.
Hence, It is subset of integers.
Hence, T ⊂ I
For 0 ∈ Z;
Zero is indeed an integer thus it is an element of Z.
Hence, 0 ∈ Z
For R ⊂ T
Since, T is the set of negative integers less than - 1.
So, Not all real numbers are some integers. Some real numbers do not meet this criteria.
Hence, R ⊄ T

The linear inequality will be 2.5x+1.5y<=9, where x=boxes of popcorn and y=no. of drinks.
What are linear inequalities?
Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.
The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.
e.g. y>x+2
Now,
Given that Shiloh and Mario went to the movies. At the theater a small box of popcorn costs $2.50 each and each drink costs $1.25 each.
Shiloh and Mario only have $9 to spend.
So, let x=boxes of popcorn and y=no. of drinks
Therefore, given statements can be satisfied by linear inequality given

Last month, Carmen paid a gas and electric utility bill of $55. The part of the bill was $30. Write the ratio of the payment for to the payment for electricity. i need the answer quick
Answers
Step-by-step explanation:
To find the ratio of the payment for gas to the payment for electricity, we can use the following formula:
(Payment for gas) : (Payment for electricity) = (Gas payment) : (Electricity payment)
We know that the total bill was $55 and the payment for electricity was $30.
So, the payment for gas would be: $55 - $30 = $25
Therefore, the ratio of the payment for gas to the payment for electricity is:
($25) : ($30) = 25 : 30
You can simplify this ratio to 5:6 or you can write it as 25:30
the pka’s for carbonic acid and bicarbonate at 37°c are 3.83 and 10.25, respectively. o i. write the equation for each of these equilibria.
Answers
The equation for the equilibrium of carbonic acid (H2CO3) and bicarbonate (HCO3-) is: H2CO3 ⇌ H+ + HCO3- and equation for the equilibrium of bicarbonate (HCO3-) and carbon dioxide (CO2) is: HCO3- ⇌ H+ + CO2.
The equation for the equilibrium of carbonic acid (H2CO3) and bicarbonate (HCO3-) is: H2CO3 ⇌ H+ + HCO3-
The equation for the equilibrium of bicarbonate (HCO3-) and carbon dioxide (CO2) is: HCO3- ⇌ H+ + CO2
At 37°C, the pKa for carbonic acid (H2CO3) is 3.83, which means that the concentration of H+ in the first equation will be 10^-3.83 = 0.000195 M. The concentration of HCO3- in the first equation will be 0.000195 M.
The pKa for bicarbonate (HCO3-) is 10.25, which means that the concentration of H+ in the second equation will be 10^-10.25 = 0.00000007 M. The concentration of CO2 in the second equation will be 0.00000007 M.
Therefore, The equation for the equilibrium of carbonic acid (H2CO3) and bicarbonate (HCO3-) is: H2CO3 ⇌ H+ + HCO3- and equation for the equilibrium of bicarbonate (HCO3-) and carbon dioxide (CO2) is: HCO3- ⇌ H+ + CO2.

solve the initial value problem. (9ye^9xy-5/y)dx (9xe^9xy 5x/y^2)dy=0, y(3)=3 the implicit solution is:
Answers
The initial value problem [tex](9ye^9xy-5/y)dx (9xe^9xy 5x/y^2)dy=0, y(3)=3[/tex] can be approximated using numerical methods such as the Euler method.
To find the initial value problem is a differential equation of the form:
[tex](9ye^(9xy) - 5/y) dx + (9xe^(9xy) - 5x/y^2) dy = 0[/tex]
with the initial condition y(3) = 3.
Since this is an implicit solution, we cannot find an explicit solution for y in terms of x. However, we can use numerical methods to find approximate solutions for y. One such method is the Euler method.
In the Euler method, we start with an initial estimate for y(x), and then use the derivative information to find y(x + h), where h is a small step size. We then use the new estimate to find the next value, and so on.
To apply the Euler method to this problem, we start with the initial condition y(3) = 3, and then use the following formula to estimate y(x + h):
y(x + h) = y(x) + h * f(x, y(x))
where f(x, y) is the derivative information from the differential equation:
[tex]f(x, y) = -(9xe^(9xy) - 5x/y^2) / (9ye^(9xy) - 5/y)[/tex]
Using the Euler method, we can iteratively estimate y(x) for increasing values of x, until we reach a desired value of x or the accuracy is within an acceptable limit.

Here the population growth is as per the Malthusian model. As per the calculations, the bacterial population will reach 10000 after 33 days.
Here the bacterial growth is as per the exponential growth curve. So the equation is,
[tex]P_{t} = P_{0} e^{rt}[/tex]
[tex]P_{t}[/tex] is the population at n
[tex]P_{0}[/tex] is the initial population
r is the time
t is the rate
Population doubles after 10 days.
So, [tex]2000 = 1000e^{r*10} \\\\\frac{2000}{1000} = e^{10r}\\\\ 2 = e^{10r\\}\\\\[/tex]
Taking logarithms on both sides
[tex]ln(2) = lne^{10r}\\\\10r = 0.693\\ \\r = 0.0693[/tex]
So the rate is 0.0693.
When population reaches 10000,
[tex]10000 =1000e^{0.0693t}[/tex]
[tex]\frac{10000}{1000} =e^{0.0693n}[/tex]
[tex]10 = e^{0.0693*t}\\ \\ln(10) = ln(e^{0.0693t}\\ \\2.3 = 0.0693t\\\\t = 2.3/0.0693\\= 33.18[/tex]

let f(x)=−x4−9x3 4x−6 . find the open intervals on which f is concave up (down). then determine the x -coordinates of all inflection points of f .
Answers
The x-coordinates of the inflection points of this function are −1 and −1/3.
In this case, we are looking for the open intervals on which the function f(x) = −x⁴ − 9x³ + 4x − 6 is concave up (down) and the x-coordinates of the inflection points of the function.
To find the open intervals on which f is concave up, we must first calculate the second derivative of the function.
The second derivative of the function f(x) is
=> f''(x) = −12x³ − 27x² + 4.
This means that the function f is concave up when f''(x) > 0 and concave down when f''(x) < 0. Solving the equation f''(x) > 0 will give us the intervals on which the function is concave up.
These are the intervals (−∞, −1), (−1, −1/3), and (−1/3, ∞).
Similarly, solving the equation f''(x) < 0 will give us the intervals on which the function is concave down. These intervals are (−1, −1/3) and (−1/3, 0).
We can now determine the x-coordinates of all inflection points of the function f by finding the x-values at which the second derivative is equal to zero.
Solving the equation f''(x) = 0 will give us the x-coordinates of the inflection points, in this case −1 and −1/3.

In ΔOPQ, p = 9.7 inches,
�
m∠Q=93° and
�
m∠O=82°. Find the length of q, to the nearest 10th of an inch.
Answers
Answer:
To find the length of q, we can use the Law of Cosines formula:
q = sqrt(p^2 + o^2 - 2 * p * o * cos(Q))
where p and o are the lengths of sides PQ and PO, and Q is the measure of the included angle between them.
Since we know that p = 9.7 inches and ∠Q = 93°, we can use the Law of Sines to find o:
sin(Q) = o/q
=> o = q * sin(Q)
=> o = 9.7 * sin(93)
Using this formula and rounding to the nearest tenth, we can find that o = 11.7 inches.
Now we can use the Law of Cosines to find q:
q = sqrt(p^2 + o^2 - 2 * p * o * cos(Q))
=> q = sqrt(9.7^2 + 11.7^2 - 2 * 9.7 * 11.7 * cos(93))
Rounding to the nearest tenth, we get that q = 17.2 inches.

The probability that the machine is up at times n = 5, 10, 15, and 20 can be calculated as n = 5: 0.773797, n = 10: 0.60653065, n = 15: 0.47000363 and n = 20: 0.35831814.
For the machine described in Conceptual Problem 2.8, the probability that the machine is up at times n = 5, 10, 15, and 20 can be calculated using the formula:
P(machine is up at time n) = P(machine was up at time n-1) * p
Given that the machine is initially up and p = 0.95, the probabilities are as follows:
n = 5: P(machine is up at time 5) = 0.95 * 0.95 * 0.95 * 0.95 * 0.95 = 0.773797n = 10: P(machine is up at time 10) = [tex]0.95^{10[/tex] = 0.60653065n = 15: P(machine is up at time 15) = [tex]0.95^{15[/tex] = 0.47000363n = 20: P(machine is up at time 20) = [tex]0.95^{20[/tex] = 0.35831814As for the transition probability matrix of the DTMC {Xn, n > 0}, the possible transitions are:
Xn = 0 to Xn+1 = 1 (1 day's worth of repair work is done) with a probability of 1 Xn = 1 to Xn+1 = 2 (machine is up) with probability pXn = 0 to Xn+1 = 0 (machine fails again) with probability 1 - pXn = 2 to Xn+1 = 2 (machine stays up) with probability pXn = 2 to Xn+1 = 0 (machine fails) with probability 1 - pThus, the transition probability matrix and the transition probability matrix of the DTMC {Xn, n > 0} can be represented as attached in the below image:

Harp seals spend much of their time swimming and diving in the icy waters of the Arctic ocean. if 86 seals dove for a combined total depth of 10,578 meters, how many meters each seal dive
pls help ASAP its literally 12:00 where i live
Answers
Answer: 122.81
Step-by-step explanation:
If 86 seals dove for a combined total depth of 10,578 meters, each seal would have dove an average of 122.81 meters (10,578 meters / 86 seals)
[tex]10578 \div 86 = 122.81[/tex]

Find all real zeros of the function y=3x+1 a. 1/3 b.-1/3 c. 3, 1 d. 3
Answers
Answer:
The zeroes of the function are: [tex]\frac{-1}{3}[/tex].
Option b would be the correct answer.
Step-by-step explanation:
The zeros of a function are defined as the point at which the value of the function is zero. We can say the zeros are the x values where the graph intersects the x-axis. We obtain these algebraically by setting the function equal to zero then solving.
Given
[tex]y=3x+1[/tex]
Lets find all real zeros of the function.
Replace [tex]y[/tex] with 0.
[tex]0=3x+1[/tex]
Subtract 1 from both sides of the equation
[tex]-1=3x[/tex]
Divide both sides of the equation by 3.
[tex]\frac{-1}{3} =\frac{3x}{3}[/tex]
Simplify the right side by cancelling the common factor of 3.
[tex]\frac{-1}{3} =x[/tex]
