1. The numbers ______ and _____ are respectively the additive and multiplicative identities of rational numbers
Answer: 0 and 1, in that order
The numbers 0 and 1 are respectively the additive and multiplicative identities of rational numbers.
===========================================================
Explanation:
The additive identity is 0 because adding 0 to any number leads to the original number. For instance, 7+0 = 7. In general we can say x+0 = x or we could also say 0+x = x.
The multiplicative identity is 1 because multiplying 1 with anything leads to that original number. Example: 1*5 = 5 or 9*1 = 1. The general template is x*1 = x which is the same as saying 1*x = x.
These ideas not only apply to rational numbers, but to real numbers as well.
Neil work a a conultant at a oftware company. The amount of hi annual bonu i baed upon the number of hour he work. B = the amount of Neil' bonu
h = the number of hour Neil work
Which of the variable i independent and which i dependent?
The independent variable is h (the number of hours Neil works) and the dependent variable is B (the amount of Neil's bonus).
In this scenario, the amount of Neil's bonus (B) is dependent on the number of hours he works (h). The number of hours he works is the input or independent variable, while the amount of bonus he receives is the output or dependent variable. It can be said that the number of hours he works is the cause and the amount of bonus is the effect.
The equation is B = f(h) where f is the function that relates the two variables.
Thus, the independent variable is h (the number of hours Neil works) and the dependent variable is B (the amount of Neil's bonus).

When treated with an antibiotic, 93% of all the dolphins are cured of a particular bacterial infection. If 6 dolphins with the particular bacterial infection are treated, find the probability that exactly 3 are cured.
Answer:
the probability is 0.00552
Step-by-step explanation:
If 93% are cured, the percentage not cured will be 100-93 = 7%
let p = probability of being cured = 93% = 93/100 = 0.93
q = probability of being uncured = 7/100 = 0.07
so we proceed to use the bernoulli approach;
we have this as;
P(X = n) = X C n p^n q^n-1
P(X = 3) = 6 C 3 * 0.93^3 * 0.07^3
P(X = 3) = 0.00552

What are the 5 operations of functions?
The 5 operations of functions are
1. Input
2. Processing
3. Output
4. Storage
5. Maintenance
Input: When a function is used, it takes in an input value. This input value is used to compute the output. For example, if a function is used to calculate the area of a circle, the input would be the radius of the circle.
Processing: Once the input value is taken, the function will use the input to perform some type of operation on it. For example, if the function is used to calculate the area of a circle, the operation would be to multiply the input by itself and then multiply it by the constant pi.
Output: The output of a function is based on the input. For example, if the function is used to calculate the area of a circle, the output would be the area of the circle.
Storage: Once the output of a function is computed, it can be stored for later use. This allows the same output to be used multiple times without having to recalculate the output.
Maintenance: Functions need to be maintained and updated over time. This can include updating the input, operation, and output, as well as any additional changes that might be needed. This ensures the function is up-to-date and still provides accurate results.

A) 81 and 80°
B) 81 and 20°
C)79° and 90°
D)79° and 21°
Answer:
B) 81 and 20°
Step-by-step explanation:
In any triangle, the sum of the measures of the three angles is 180°. Therefore, if two angles in a triangle have measures of 79° and 81°, the third angle must have a measure of 180 - 79 - 81 = 20°. Therefore, the answer is B) 81 and 20°.

does the order of the quantities in an inequality matter
The order of the quantities in an inequality matters. Therefore, it is true.
How to illustrate the inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The most frequent application is to size-compare two numbers on a number line.
When resolving an inequality, you can do one of the following: Add the same amount to each side; Subtract the same amount from each side; Multiply or divide each side by the same positive amount. You must flip the inequality symbol if you multiply or divide each side by a negative number.
Therefore, the order matters.

Find the first 5 terms of the sequence
A(n)=n+A(n-1) a1 = 3
Answer:
A(1) = 3, A(2) = 5, A(3) = 8, A(4) = 12, A(5) = 17
Step-by-step explanation:
Given A(n) = n + A(n–1) a1 = 3.
A(1) = 3.
A(2) = (2) + A(2–1)
= (2) + A(1)
= (2) + (3) = 5
A(3) = (3) + A(3-1)
= (3) + A(2)
= (3) + (5) = 8
A(4) = (4) + A(4–1)
= (4) + A(3)
= (4) + (8) = 12
A(5) = (5) + A(5–1)
= (5) + A(4)
= (5) + (12) = 17

Step-by-step explanation:
We can represent Xavier's running in the following ratio using the given information:
distance : time
13 miles : 182 minutes
To get the answer to this problem, all we have to do is divide both sides of the ratio by 13, so that the left side is 1 mile.

How do you solve composite functions examples?
The composite function is the result of first applying the function (x^2 - 1) to the input and then applying the function (5x + 2) to the result. The final result of the composite function is 5x^3 + 2x - 3.
Step 1: Apply (x^2 - 1) to the input:
(x^2 - 1) = x^2 - 1
Step 2: Apply (5x + 2) to the result:
(5x + 2)(x^2 - 1)
= 5x^3 - 5x + 2x - 2
Step 3: Simplify:
5x^3 - 5x + 2x - 2
= 5x^3 + 2x - 3
A composite function is the result of applying two or more functions in succession. The order of operations for a composite function is to first apply the first function, then apply the second function to the result of the first, and so on. In the example given, the composite function
f(x) = (5x + 2) ∘ (x^2 - 1)
is the result of first applying the function
(x^2 - 1)
to the input and then applying the function (5x + 2) to the result. The calculation can be broken down into three steps: Step 1 is to apply (x^2 - 1) to the input to get x^2 - 1, Step 2 is to apply (5x + 2) to the result to get 5x^3 - 5x + 2x - 2,
and Step 3 is to simplify the result to get the final answer of
5x^3 + 2x - 3.
To summarize, the composite function

Answer:
a) Its first term, a₁ -1,190
b) Its second term, a₂ = -1,186
c) Its third term, a₃ = -1,182
Step-by-step explanation:
The 100th term of the arithmetic progression, AP = 406
The common difference of the AP = 4
The formula to find the nth term of an AP, aₙ is given as follows;
aₙ = a + (n - 1)·d
Where;
aₙ = The nth term of the AP
a = The first term of the AP
a) Given the 400th term and the common difference, we have;
a₄₀₀ = 406 = a + (400 - 1) × 4
406 = a + 399 × 4
a = 406 - 399 × 4 = -1,190
The first term of the AP, a = -1,190
b) The second term of the AP, a₂ = -1,190 + (2 - 1) × 4 = -1,186
The second term of the AP, a₂ = -1,186
c) The third term of the AP, a₃ = -1,190 + (3 - 1) × 4 = -1,182
The third term of the AP, a₃ = -1,182.

Two alien pacehip tart traveling toward each other from pace tation that are 710,000 km apart. The firt pacehip tarted an hour before the econd pacehip and i traveling at 110,000 km/hr. In how many hour will the two pacehip meet if the econd pacehip i traveling at 90. 000 km/hr?
The two spaceships will meet in 8 hours if the second spaceship is traveling at 90. 000 km/hr.
To calculate the time it will take for the two spaceships to meet, you must use the equation Distance = Rate x Time. Since the first spaceship has a higher rate of speed, it will reach the second spaceship in less time than it would take the second spaceship to reach the first.
This means that the time it takes for the two spaceships to meet will be equal to the time it takes for the first spaceship to travel the distance between the two space stations. We can use the equation to solve for time: Time = Distance/Rate. In this case, the distance is 710,000 km and the rate is 110,000 km/hr, so the time is 6.45 hours.

The graph shows the reciprocal parent function
Which statement best describes the function
The statement that best represents the function must be identified by reading the graph.
Let's check which of the following statements best characterizes the function:A) When x < 0, the function is negative.
This is accurate; as you can see, the function is negative for x < 0 because it is below the horizontal axis.
We shall see that choice A is the proper one. "When x < 0, the function is negative."
The function tends to infinity on the positive side at an x close to zero.
The function tends to negative infinity at x close to zero on the negative side.
The function tends to zero as x's absolute value grows.
So we can conclude that this is an inverse function similar to:
