The simplified form of the first expression is -37 + 6i and the second expression is -16 - 14i.
What is the arithmetic operations?
Arithmetic operations are basic mathematical operations that can be performed on numbers, such as addition, subtraction, multiplication, and division.
The first expression is 7 - (3 + 41) + 6i. To simplify this expression, we need to first simplify the parentheses. Inside the parentheses, we have 3 + 41 = 44. So the expression becomes:
7 - 44 + 6i
Next, we can simplify the arithmetic operations by combining like terms:
7 - 44 + 6i = -37 + 6i
The second expression is -10 + (6 - 5i) - 9i. Similar to the first expression, we need to simplify the parentheses first. Inside the parentheses, we have 6 - 5i = 6 - 5i. So the expression becomes:
-10 + 6 - 5i - 9i
Next, we can simplify the arithmetic operations by combining like terms:
-10 + 6 - 5i - 9i = -16 - 14i
Hence, the simplified form of the first expression is -37 + 6i and the second expression is -16 - 14i.

The number of white balls is equally likely to be any number between 1 and n − 1.
This problem can be solved by considering the number of ways to get a certain number of white balls in the bin. Since each ball can either be white or black, there are 2^n possible sequences of n balls in the bin.
Now consider the number of ways to get exactly k white balls in the bin. It can be done in the following way:
Choose k white balls out of n balls, which can be done in C(n, k) ways, and then arrange the k white balls and n-k black balls in (n-k + k)!/(n-k)!k! ways.
Therefore, the number of ways to get exactly k white balls in the bin is C(n, k)(n-k + k)!/(n-k)!k! = C(n, k)(n!)/(n-k)!k!.
Since each sequence of balls is equally likely, it follows that the number of white balls is equally likely to be any number between 1 and n - 1.

The population (in millions) of Calcedonia as a function of time t (years) is P(1) = 55 . 20^005t. Determine the number of years it takes the population to double. (Give an exact answer. Use symbolic notation and fractions where needed.) years: Let g(t) = a2^kt. Determine the expression for g(t + 1/ķ) (for any positive constants a and k). (Express numbers in exact form. Use symbolic notation and fractions where needed. Give the expression in terms of a, k, and t.
g(t+1/k)
Interpret the obtained results. - The population does not change significantly over time. - The population increases by 1/k after one year. - The population doubles after 1/k years - The population halves after 1/k years
Give the expression in terms of a, k, and t is g(t+1/k) = a2^(k(t+1/k)) = a2^kt * 2^(1/k)
The population doubles when P(t) = 2 * P(0), so we can set up the equation:
2 * 55 = 20^(5t)
Solving for t:
t = log(2)/(5 * log(20)) = log(2)/log(400)
The population doubles after approximately 0.173 years or 63.1 days.
g(t+1/k) = a2^(k(t+1/k)) = a2^kt * 2^(1/k)
Interpretation: g(t+1/k) is the population at time t+1/k, where a and k are positive constants. The population at t+1/k is equal to the population at time t multiplied by 2^(1/k). This means that if k is a large number, the population will change very little over time, if k is a small number, the population will change more quickly.

The table 1 represent the function From the given figure.
What is function ?
The function in mathematical terms is the mapping of each member of a set (named as a domain) to another set of members (named as a codomain). This term has a different meaning from the same word that is used every day, such as "the tool works well." The concept of function is one of the basic concepts of mathematics and any quantitative science. The terms "function", "mapping", "map", "transformation" and "operator" are usually used synonymously.
In function, there are several important terms, including:
The domain is the area of origin of the function f denoted by Df.
Codomain is the area where the f function area is denoted by Kf.
The range is the result area which is a subset of the codomain. The function range f is denoted by Rf.
PROPERTIES OF FUNCTIONS
1. INJECTIVE FUNCTION
Called one-on-one function. Suppose the function f represents A to B, then the function f is called a one-on-one function (injective), if each two different elements in A will be mapped to two different elements in B. Furthermore, it can be said briefly that f: A → B is injective function if a ≠ b results in f (a) ≠ f (b) or equivalent if f (a) = f (b) then the effect is a = b.
2. SURJECTIVE FUNCTION
Function f: A → B is called a function to or objective function if and only if for any b in the B domain can be at least one an in domain A so f (a) = b applies. In other words, a codomain of the objective function is the same as its range.
3. BIJECTIVE FUNCTION
A mapping off: A → B is such that f is both an injective and objective function at once, so it is said "f is a function of wisdom" or "A and B are in one-to-one correspondence".
Therefore, The table 1 represent the function From the given figure.

What is Larry's average velocity, in m/min, during each of these two intervals. Find v1 and v2.
Larry ran at an average velocity of 66.7 m/min to the lamppost 200 m away and an average velocity of 250 m/min to the tree 1000 m away.
v1 = 200 m / 3 min = 66.7 m/min
v2 = 1000 m / 4 min = 250 m/min
Larry left his home at 9:06 and ran at a constant speed to the lamppost 200 m away. He arrived at the lamppost at 9:09. Immediately after arriving, he turned around and ran to a tree 1000 m away, arriving at 9:13. To find his average velocity during each interval, we can divide the distance traveled by the time it took to travel the distance. For the first interval, Larry traveled 200 m in 3 minutes, so his average velocity was 200 m divided by 3 min, or 66.7 m/min. For the second interval, Larry traveled 1000 m in 4 minutes, so his average velocity was 1000 m divided by 4 min, or 250 m/min.

A plant is already 10.25 meters tall, and it will grow 5 centimeters every month. The plant's height, H (in meters), after x months is given by the following
function.
H(x)=0.05x+10.25
What is the plant's height after 30 months?
On solving the function H(x) = 0.05x + 10.25, the plant's height after a period of 30 months is obtained as 11.75 m.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The height of the plant is = 10.25 m
The rate at which plant grows is = 5 cm/month or 0.05m/month
The function for plant's height is given as - H(x) = 0.05x + 10.25
To find the plant's height after 30 months, substitute the value of x with 30 in the function -
H(30) = 0.05(30) + 10.25
Use the arithmetic operation of multiplication -
H(30) = 1.5 + 10.25
Use the arithmetic operation of addition -
H(30) = 11.75
Therefore, the plant's height after 30 months will be 11.75 m.

5. Nicolet is fencing off a rectangular pen for her chickens. She has 80 feet of fencing and will use all of it. The area of the pen, A(x), is a function of its length, x, in feet.
The domain of the area function is given by the following interval:
(0, 40).
How to obtain the domain of the function?The domain of a function is the set composed by all the input values that the function accepts.
On the graph, the domain of the function is given by the values of x.
Considering the graph, the domain is given by the following interval:
(0, 40).
It is an open interval because if x = 0, then the length is of zero, and if x = 40, then the width is of zero, meaning that these dimensions are not possible.

The value of BD is 12cm.
What is Pythagoras' 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.
Here, we have
BE = ED (as E is the center of BD - property of a kite).
By Pythagoras' theorem:
10² = 8² + BE²
BE² = 10² - 8² = 36
BE = 6
So BD = 2*6 = 12.
Hence, the value of BD is 12cm.

Answer:
The gas mileages (in miles per gallon) for 35 cars are shown in the frequency distribution. This means that the gas mileage of 35 cars has been recorded and grouped into categories. The categories are 27-30, 31-34, 35-38, and 39-42. The frequency is the number of cars in each category. For example, there are 12 cars that have a gas mileage between 27 and 30 miles per gallon. Approximating the mean of the frequency distribution means finding the average gas mileage of all the 35 cars. To do this, you need to add the gas mileages of all the 35 cars and divide the sum by 35. The approximate mean of the frequency distribution is 33.4 miles per gallon. An analogy that can help you understand this concept is that of a classroom full of students. If you want to calculate the average height of the students, you would need to add up the heights of all the students and divide the sum by the total number of students. The same concept applies to the frequency distribution.

There a rule for logarithms:
[tex]\log_n(a^m) = m \cdot \log_n(a)[/tex]
So when you're working with [tex]\log_5(a^3)[/tex], we can use that rule to rewrite this as
[tex]\log_5(a^3) = 3 \cdot \log_5(a)[/tex]
And since the first part tells us (on paper) that [tex]\log_5(a) = 2[/tex], then we can say
[tex]\log_5(a^3) = 3 \cdot \log_5(a) = 3 \cdot 2 = 6[/tex]
