As a result, the answer to the provided linear equation problem is that the iteration runs in an acceptable amount of time and does not rise exponentially.
What exactly is a linear equation?A linear equation is represented by the algebraic expression y=mx+b. B is the y-intercept, and m is the slope. A "simple formula with 2 factors," where both y and x are variables, is what the previous sentence was referred to as. Calculations with two variables are referred to as "bivariate linear equations." Here are a few illustrations: 2x - 3 = 0; 2y = 8; m + 1 = 0; x/2 = 3; x + y = 2; and 3x - y + z = 3 are the results. A mathematical equation is considered to be linear if its solution has the format y=mx+b, where m stands for the slope and b for the y-intercept.
Here,
Based on how quickly iterations rise as input increases, fair and unreasonable algorithms can be distinguished. Since the algorithm does not grow exponentially, we can infer that it completes in an acceptable amount of time.
assessing the mathematical function that represents the algorithm's growth rate when input is added;
200 = 10k, where k is the proportionality constant.
k = 200/10
k = 20
The function that represents the number of iterations is as a result:
I = input size; n = 20i; represents the number of iterations.
As a result, the answer to the provided linear equation problem is that the iteration runs in an acceptable amount of time and does not rise exponentially.

A line which is perpendicular to this line would have a slope of ___.
Write your answer as a whole number or simplified fraction or improper fraction (not a decimal or mixed number). Use a / for a fraction bar.
Answer:
1/2
Step-by-step explanation:
A line that is perpendicular to another has an opposite reciprocal slope. In this case, we can see that the slope of the given line is -2, so the perpendicular line would have a slope of 1/2.
Answer:
1/2
Step-by-step explanation:
The slope of a line perpendicular to any given line is the negative reciprocal of the given line's slope:
[tex]m_\perp = \dfrac{1}{m}[/tex]
In this problem, the slope of the given line is [tex]\dfrac{-2}{1}[/tex] (rise over run).
So, to find the slope of a line that is perpendicular to it, we simply flip the given line's slope and change its sign.
[tex]m_\perp = \dfrac{1}{2}[/tex]
So, a line which is perpendicular to the given line would have a slope of 1/2.

5. $10,800 in clothing sales gives Rachel a 1,230 paycheck
6. $ 16,000 in clothing sales gives Rachel a 1,450 paycheck
The equation representing Rachel's paycheck = amount she earns every month + commission
If she makes $100 in clothing sales, her paycheck = $150 + (0.1 x 100) = $160
If she makes $1100 in clothing sales, her paycheck = $150 + (0.1 x 1100) = $260
If she makes $2200 in clothing sales, her paycheck = $150 + (0.1 x 2200) = $370
If she makes $4200 in clothing sales, her paycheck = $150 + (0.1 x 4200) = $570
If she makes $10800 in clothing sales, her paycheck = $150 + (0.1 x 10800) = $1230
If she makes $16000 in clothing sales, her paycheck = $150 + (0.1 x 16000) = $1750

How can you use cause-and-effect relationships to explain how the difference in air pressure results in the wind direction that you saw in the photograph?
Answer: Hope This Helps!
Step-by-step explanation:
Changes in air pressure are determined by a variety of forces, including the density and temperature of air masses. When air moves from between areas of high pressure and low pressure, wind directions and speeds may change. The driving force behind changes in air pressure and therefore the creation of wind is gravity.

What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
The quadratic equation,
y = x² – 2x + 5
To find the value of x:
When y = 6.
So,
x² – 2x + 5 = 6
x² – 2x - 1 = 0
Comparing the quadratic equation with standard quadratic equation,
ax²+ bx +c = 0
We get,
a = 1, b = -2 and c = -1
So,
x = {-b ±√(b²-4ac)}/2a
Substituting the values,
x = (2±√8)/2
x = 1 ± √2
x = 2.41421 and x = −0.414214
And the graph is drawn on the left so x = −0.414214 = -0.4 to one decimal place.
Therefore, the value of the x is -0.4.

DE is parallel to AC. Find the lengths of AC and AD. FAST!!!
Answer:
we have:
∆BDE is similar to ∆BAC
so their side are proportional :
BD/BD=BE/BC
2/BD=4/(6+4)
BD=2×10/4
BD=5
again
BE/BC=DE/AC
4/10=5/AC
AC=5×10/4
AC=25/2
Now,
AC=25/2 or 12.5.
AD=BA-BD=5-2=3.
is your answer.
Answer:
AC = 12.5, AD = 3
Step-by-step explanation:
A line parallel to a side of a triangle and intersecting the other 2 sides, divides those sides proportionally, that is
[tex]\frac{BD}{BE}[/tex] = [tex]\frac{AD}{CE}[/tex] , substitute values
[tex]\frac{2}{4}[/tex] = [tex]\frac{AD}{6}[/tex] ( cross- multiply )
4 AD = 12 ( divide both sides by 4 )
AD = 3
-----------------------------------------
Δ BDE and Δ BAC are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{DE}{AC}[/tex] = [tex]\frac{BD}{BA}[/tex] , substitute values
[tex]\frac{5}{AC}[/tex] = [tex]\frac{2}{5}[/tex] ( cross- multiply )
2 AC = 25 ( divide oth sides by 2 )
AC = 12.5

2. A computer valued at $6500 depreciates at the rate of 14.3% per year. a. Write a function that models the value of the computer. b. Find the value of the computer after 3 years
Answer:
$4088.5
Step-by-step explanation:
Given data
Price a = $6500
Rate of depreciation r= 14.3%
Time x= 3 years
The exponential function Decay is described as
y= ab^x
For decay
b= 1-r
a.
Hence the exponential function that model the value of the computer is
y=a(1-r)^x
b.
y= 6500(1-0.143)^3
y= 6500*(0.857)^3
y= 6500*0.629
y=$4088.5
Hence the value of the computer after 3 years is $4088.5

The correlation coefficient r between the size of a lake in square miles, x, and the yearly number of registered boaters, y, is 0.743. What percent of the variation in the number of yearly boaters can be explained by differences in lake sizes
Answer:
55.2049%
Step-by-step explanation:
R², the coefficient of determination, is the proportion of the variation in the dependent variable that is predictable from the independent variable.
In this case, if we square our correlation coefficent r=0.743, we get R²=0.552049, which means that 55.2049% of the variation in the number of yearly boaters can be explained by differences in lake sizes

After Myong's cylindrical birthday cake was sliced, she received the slice at right. If her birthday cake originally
had a diameter of 14 inches and a height of 6 inches, find the volume of her slice of cake.
Answer:
97.53 in³
Step-by-step explanation:
The cylindrical birthday cake has a diameter (d) of 14 inches and a height (h) of 6 inches.
The radius of the cake (r) = diameter / 2 = 14 inches / 2 = 7 inches.
The volume of the full cake = πr²h = π(7²)6 = 924 in³
Since only a part of the cake was cut and given to Myong. The total measure of the cake is 360°, but the part given to her was 38°. Hence the volume of her slice is given as:
Volume of her slice = (38 / 360) * volume of the full cake = (38 / 360) * 924 = 97.53 in³
Volume of her slice = 97.53 in³
