What is the short definition of a linear equation?
An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."a) From the meaning of title -
f(t) = 3000t + 34000 { from 2020 it will be increase by 300 people
per year}
b) f(b) = 3000 × 6 + 34000

Let f(t) be the population (in thousands of people) of Math City, as a function the time t (in years), where t = 0 corresponds to the year 2020. In 2020, the population was 34000, and each year the population increases by 3000 people. (a) Model the population by finding a formula for f(t), using the appropriate choice of a linear, polynomial, power, trigonometric, or exponential function, or a piecewise combination thereof.

The vertical asymptote of the function = ln(x-6) + 5 is:
O A. x = -6
B. x = -5
O C. x = 6
D. x = 5
The vertical asymptote of the function = ln(x-6) + 5 is option C: x = 6.
The given function is f(x) = ln(x - 6) + 5.
A vertical asymptote is a vertical line that a function approaches but never crosses as it approaches infinity or negative infinity. For a logarithmic function like ln(x), the domain of the function is restricted to positive values only since the natural logarithm is undefined for non-positive arguments.
In the given function, we have f(x) = ln(x - 6) + 5. To find the vertical asymptote, we need to identify the value of x that would make the argument of the natural logarithm equal to zero.
Let's set the argument of the natural logarithm to zero:
x - 6 = 0
Now, solve for x:
x = 6
Thus, the value of x that would make the argument of the natural logarithm zero is x = 6.
So, the correct answer is option C: x = 6.
This means that the vertical asymptote of the function f(x) = ln(x - 6) + 5 is the vertical line x = 6. As x approaches 6 from either side (but never equaling 6), the function's values approach infinity. Similarly, as x approaches negative infinity, the function's values also approach infinity. The function never crosses the vertical line x = 6.

a. When x =-4 then f(x) = -x+4
b. When x = -2 then f(x) = -x+4
c. When x = -1 then f(x) = -x+4
d. When x=1/2 then f(x) = 3

Given, g(x) = {-x+4 , if x≤-1

a. when x = -4, f(x) = ?

therefore when x=-2 ⇒ f(x) = -x+4

please help with this question. n refers to the number of sides.
Answer:
n = 18
Step-by-step explanation:
The sides in a regular polygon are equal in length.
⇒ BC = CD
If BC = CD then ΔDCB is an isosceles triangle.
As the base angles of an isosceles triangles are equal:
⇒ ∠DBC = ∠BDC = 10°
Interior angles in a triangle sum to 180°.
⇒ ∠DBC +∠BDC + ∠DCB = 180°
⇒ 10° + 10° + ∠DCB = 180°
⇒ 20° + ∠DCB = 180°
⇒ ∠DCB = 180° - 20°
⇒ ∠DCB = 160°
Therefore, the interior angle of the regular polygon is 160°.
The interior angles of a regular polygon are equal in size.
[tex]\boxed{\begin{minipage}{5.2 cm}\underline{Interior angle of a polygon}\\\\$\dfrac{(n-2) \times 180^{\circ}}{n}$\\\\where $n$ is the number of sides.\\ \end{minipage}}[/tex]
To find the number of sides, equate the formula to the found value of the interior angle and solve for n:
[tex]\begin{aligned}\implies\dfrac{(n-2) \times 180^{\circ}}{n} & =160^{\circ}\\(n-2) \times 180^{\circ} & =n \times 160^{\circ}\\ 180(n-2) & = 160n\\180n-360 & = 160n\\180n & = 160n+360\\180n-160n & = 360\\20n & = 360\\n &= \dfrac{360}{20}\\n & =18\\\end{aligned}[/tex]
Therefore, the regular polygon has 18 sides.

It can also be described as a rectangle with two adjacent sides of equal length. It is the only frequent polygon with internal, central, and external angles that are all equal (90°) and diagonals that are all identical in length. ▢ABCD denotes a square with vertices ABCD.So,

Answer: The converse of this theorem is also true; that is, if two lines n and m are cut by a transversal so that the alternate interior angles are congruent, then n║m.
Step-by-step explanation:
What does it mean converse in geometry?
The converse of a statement is formed by switching the hypothesis and the conclusion. The converse of "If two lines don't intersect, then they are parallel" is "If two lines are parallel, then they don't intersect." The converse of "if p, then q" is "if q, then p."
So, in the figure below, if we can choose n║m, then ∠1≅∠2
Since n║m , by the corresponding Angles Postulate,
∠1≅∠2.
Therefore, by the definition of congruent angles,
m∠1=m∠2
Since ∠1 and ∠2 form a linear pair, they are supplementary, so
m∠1+m∠2=180°.
Therefore, the converse of this theorem is also true; that is, if two lines n and m are cut by a transversal so that the alternate interior angles are congruent, then n║m.

The correct option is (b) sample size.
In the formula for calculating the standard deviation, the letter n represent sample size.
What is standard deviation?
Standard deviation is a statistical standard measure in finance that, when applied to an investment's annual rate of return, sheds light on its historical volatility.
Some key features regarding the standard deviation are-
The higher the standard deviation of a security, the larger the variance between every price and the mean, indicating a wider price range.A volatile stock, for example, has a high standard deviation, whereas a stable blue-chip stock has a low deviation.A square root of a value deduced from correlating data points to a population's collective mean is used to calculate standard deviation. The formula is:
Standard Deviation = [tex]\sqrt{\frac{summation n to i=1 (x_{i}-bar x )}{n-1} }[/tex]
Where,
[tex]x_{i}[/tex]= value of the i th point the the given data set.
[tex]barx[/tex]= mean value
n = total number of data points.
Thus, the standard deviation, on the other hand, determines all ambiguity as risk, even when it is in the investor's favor, like above-average returns.

A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the
5% and the 40% solutions should she mix to get the solution she needs?
The volume required for a 5% solution is 5.7 L, while a 40% solution requires 4.3 L for the experiment.
What is defined as the percentage?A percentage is a fraction of a whole represented as a number ranging from 0 and 100.
In this question, you would like to make a 10 litre 20% solution by combining 5% and 40% concentrations. This question should have multiple answers. Supposing that total volume of the 5% and 40% solutions is 10 L (no solution wasted), you can calculate the volume of solution required.The equation should be as follows:
If 'x' is the volume of a 40% solution, then the volume of a 5% solution is:
10 L = 40% solution volume + 5% solution volume
10 L = x + 5% volume of solution
10 L - x = 5% solution volume
The volume would then be calculated as follows:
(volume 20% × concentration 20%) = (volume 40% × concentration 40%) + (volume 5% × concentration 5%)
10 litre × 20% = x litre × 40% + (10- x) litre × 5%
10 L × 20% = x litre × 35% + 10 litre × 5%
x litre × 35 = 10 L × 20 - 10 L × 5
= 10 L × 15
x litre = 10 L × 15/35
x litre = 4.28 L
x litre = 4.3 L
40% solution volume = 4.3 L
The volume of 5% solution is equal to 10 L - 4.3 L = 5.7 L.
Thus, the volume of 5% solution requires is 5.7 L and volume of 40% solution required is 4.3 L.
