No, this linear relationship is not proportional, because the ratio between Chandler's hourly wage and tips changes because the number of hours worked changes
Proportional relationships are those wherein the ratio between the two portions being as compared stays constant, no matter the values of those quantities.
In this case, we're evaluating Chandler's earnings primarily based on her hourly wage and her hints from take-out orders.
But, the ratio between Chandler's hourly wage of $15.25 and her tips of $25 per night varies relying on the number of hours she works.
For example, if Chandler works for 2 hours, her total income could be $30.50 (2 x $15.25) + $25 = $55.50.
If she works for four hours, her total earnings would be $61 (4 x $15.25) + $25 = $86. In this example, the ratio among her hourly salary and tips adjustments as her income increase with more hours worked.
Therefore, because the ratio between Chandler's hourly wage and tips changes because the number of hours worked changes, this linear relationship is not proportional.

Jesus works at a computer outlet. He receives a bi-weekly salary of
$300 plus 5. 5% commission on his sales. In the last two weeks, he sold
$16,200 of computer equipment. He pays 8% for State Income Tax,
12. 3% for Federal Income Tax, 6. 3% for Social Security, and 1. 45%
for Medicare. What steps did I take to find Jesus' net bi-weekly
pay? (Show your work)
Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.
To find Jesus' net bi-weekly pay, I followed these steps:
Calculate Jesus' commission: Jesus sold $16,200 of computer equipment, so his commission is 5.5% of $16,200, which is $891.
Calculate Jesus' gross bi-weekly pay: Jesus receives a bi-weekly salary of $300 plus his commission of $891, so his gross bi-weekly pay is $1,191.
Calculate Jesus' deductions: Jesus pays 8% for State Income Tax, 12.3% for Federal Income Tax, 6.3% for Social Security, and 1.45% for Medicare. To calculate the deductions, I multiplied his gross bi-weekly pay by each percentage rate:
State Income Tax: 8% of $1,191 = $95.28
Federal Income Tax: 12.3% of $1,191 = $146.67
Social Security: 6.3% of $1,191 = $75.09
Medicare: 1.45% of $1,191 = $17.27
Subtract the deductions from the gross bi-weekly pay: To find Jesus' net bi-weekly pay, I subtracted the total deductions of $334.31 from his gross bi-weekly pay of $1,191:
Net bi-weekly pay = $1,191 - $334.31 = $856.69
Therefore, Jesus' net bi-weekly pay is $856.69 after paying his taxes and deductions.

Step 2: Construct regular polygons inscribed in a circle.
B) The completed construction of a regular hexagon is shown below. Explain why △ACF is 30°-60°-90° triangle. (10 points)
The explanation on why △ACF is 30°-60°-90° triangle is given below.
How to explain the informationWith a regular hexagon, each of its sides and angles are equal in measure. Consider the centre of the encompassing circle, connected to two neighbouring vertices - labeled A and B here. This then creates a radius wherein the length of AB is basically equal to any other side, denoted as 's'. Furthermore, △ABF will be an isosceles triangle (with AB = BF).
From these facts, we can produce △ACF which is a right angled triangle – with AC being its hypotenuse, A F and FB both equating to s/2, finally concluding that ∠AFB is equivalent to 120°/2 = 60° while establishing that ∠ACF is also a right angle constituent making △ACF essentially a 30°-60°-90° triangle.

write out all the work used to determine the answer to the question.
Each of the three sisters owes $75 to cover the cost of hiring the karaoke deejay for Taylor's graduation party.
To determine how much each sister owes, we need to first calculate the total cost of the party and then divide that cost by three, since there are three sisters splitting the cost.
1. Tent rental: $45
2. Microphone system: $60
3. Deejay cost: $30/hour × 4 hours = $120
Now, we'll add these costs together to find the total cost:
Total cost = $45 (tent) + $60 (microphone) + $120 (deejay) = $225
Finally, we'll divide the total cost by the number of sisters (3) to find out how much each sister owes:
Amount owed per sister = $225 (total cost) ÷ 3 (sisters) = $75
So, each sister owes $75 for the karaoke deejay at Taylor's graduation party.

Find the slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)). Slope of secant line = c. Find the slope of the tangent line at (6, f(6)). Slope of the tangent line d. Find the equation of the tangent line at (6, f(6)). y =
The equation of the tangent line at (6, f(6)) is y = 6x - 48.
a. The slope of the secant line joining (2, f(2)) and (7, f(7)) is:
slope = (f(7) - f(2)) / (7 - 2)
We can find f(7) and f(2) by plugging in x = 7 and x = 2 into the expression for f(x):
f(7) = 7² - 6(7) = 7
f(2) = 2² - 6(2) = -8
Substituting these values into the slope formula, we get:
slope = (7 - (-8)) / (7 - 2) = 3
Therefore, the slope of the secant line joining (2, f(2)) and (7, f(7)) is 3.
b. The slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is:
slope = (f(6 + h) - f(6)) / ((6 + h) - 6) = (f(6 + h) - f(6)) / h
We can find f(6) and f(6 + h) by plugging in x = 6 and x = 6 + h into the expression for f(x):
f(6) = 6² - 6(6) = -12
f(6 + h) = (6 + h)² - 6(6 + h) = h² - 6h + 36 - 36 - 6h = h² - 12h
Substituting these values into the slope formula, we get:
slope = (h² - 12h - (-12)) / h = h - 12
Therefore, the slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is h - 12.
c. The slope of the tangent line at (6, f(6)) is the derivative of f(x) at x = 6:
f'(x) = 2x - 6
f'(6) = 2(6) - 6 = 6
Therefore, the slope of the tangent line at (6, f(6)) is 6.
d. To find the equation of the tangent line at (6, f(6)), we use the point-slope form of a line:
y - f(6) = f'(6)(x - 6)
Substituting f(6) and f'(6) into this equation, we get:
y - (-12) = 6(x - 6)
Simplifying, we get:
y = 6x - 48
Therefore, the equation of the tangent line at (6, f(6)) is y = 6x - 48.

5+sin(3x)=4
solve for x on the unit circle where x is between 0 and 2pi
The solutions for x between 0 and 2π are: x = π/2, (5π)/6, and (11π)/6.
To solve the equation 5 + sin(3x) = 4 for x on the unit circle, where x is between 0 and 2π, follow these steps:
1. Subtract 5 from both sides: sin(3x) = -1
2. Determine the angle for which sin is -1: sin(3x) = sin(3π/2)
3. Since the sine function has a period of 2π, the general solution is: 3x = 3π/2 + 2πk, where k is an integer.
4. Divide both sides by 3: x = π/2 + (2πk)/3
Now, find the values of x between 0 and 2π by trying different integer values of k:
- If k = 0, x = π/2
- If k = 1, x = π/2 + 2π/3 = (5π)/6
- If k = 2, x = π/2 + 4π/3 = (11π)/6
Thus, the solutions for x between 0 and 2π are: x = π/2, (5π)/6, and (11π)/6.

a florida citrus grower estimates that if 60 orange trees are planted, the average yield per tree will be 400 oranges. The average yield will decrease by 4 oranges per tree for each additional tree planted on the same acreage. Express the grower's total yield as a function of the number of additional trees planted, draw the graph and estimate the total number of trees the grower should plant to maximize yield.
Answer: 80 trees
Step-by-step explanation:
YIELD = (NUMBER OF TREES)*(NUMBER OF ORANGES PER TREE)
Let's assume NUMBER OF TREES = 60 + x, where x is the number of additional trees above 60
The NUMBER OF ORANGES PER TREE will = (400-4x). Hence:
YIELD = (60+x)*(400-4x) = 24000-240x+400x-4x2 = -4x2 + 160x + 24,000
To find the maximum YIELD, take the derivative of YIELD wrt x, set it to zero, and solve for x:
d(YIELD)/dx = -8x + 160
0 = -8x +160
8x = 160
x = 20
The grower should grow 60 + 20 = 80 trees to maximize yield.

2)1/10 and 3/10
3)2/7 and 3/5
The five rational numbers between -1/5 and 1/5 are:-1/6, -1/10, 0, 1/10 and 1/6
2) The five rational numbers between 1/10 and 3/10 are: 1/10, 3/30, 5/30, 7/30, and 9/30
3) the five rational numbers between 2/7 and 3/5 are 1/5, 12/35, 13/35, 2/5, and 3/7.
What is the rational numbers?To find the five rational numbers between -1/5 and 1/5, we need to see the common difference between these numbers.
The difference between the two fractions is 1/5 - (-1/5)
= 2/5.
To find the common difference between the five fractions, we divide 2/5 by 6 so it will be
2/5 ÷ 6
= 1/15
So we need to begin with -1/5 and add 1/15 repeatedly to get the five fractions:
-1/5 + 1/15 = -1/6
-1/6 + 1/15 = -1/10
-1/10 + 1/15 = 0
0 + 1/15 = 1/10
1/10 + 1/15 = 1/6
2. To find the five rational numbers between 1/10 and 3/10, the difference between the two fractions is"
3/10 - 1/10 = 2/10 = 1/5.
So we divide 1/5 by 4
1/5 ÷ 4 = 1/20
Hence:
1/10 + 1/20 = 1/10
1/10 + 2/20 = 3/30
1/10 + 3/20 = 5/30
1/10 + 4/20 = 7/30
1/10 + 5/20 = 9/30 = 3/10
3. One need to find a common denominator for 2/7 and 3/5, which is 35.
Convert both fractions to have a denominator of 35:
2/7 = 10/35
3/5 = 21/35
So to get the rational number, it will be:
10/35 + 1/35 =11/35 = 1/5 10/35 + 2/35 = 12/35 10/35 + 3/35 == 13/3510/35 + 4/35 = 14/35 = 2/5 10/35 + 5/35 = 15/35 = 3/7Learn more about rational numbers from

An 8-inch-by-4-inch hole is cut from a
rectangular metal plate, leaving borders
of equal width x on all four sides. The
area of the metal that remains is 32 in².
The equation (8 + 2x)(4+2x) - 32 = 32
models the area of the plate. What is the
value of x, the frame width?
Answer:
2 inches
Step-by-step explanation:
The area of the metal plate can be calculated by subtracting the area of the hole from the area of the original plate. The area of the original plate is:
8 inches x 4 inches = 32 square inches
The area of the hole is:
8 inches x 4 inches = 32 square inches
So the area of the metal that remains is:
32 square inches - 32 square inches = 0 square inches
According to the equation given, we know that:
(8 + 2x)(4 + 2x) - 32 = 32
Expanding this equation we get:
32 + 16x + 8x + 4x^2 - 32 = 32
Simplifying and rearranging we get:
4x^2 + 24x - 32 = 0
Dividing both sides by 4 we get:
x^2 + 6x - 8 = 0
We can solve this quadratic equation by factoring:
(x + 4)(x - 2) = 0
So x = -4 or x = 2. Since the width of the frame cannot be negative, the only valid solution is x = 2.
Therefore, the frame width is 2 inches.
The population p of a city founded in january 2009 is modeled by p(t) = 10000e*t, where t is
the time in years.
if the population was 30,000 in 2014, determine the growth rater. then, complete the model.
The population model is complete, with p(t) = 10000e(0.2197t), and the city's population is growing at a rate of about 0.2197 each year.
To determine the growth rate and complete the model for the population of a city founded in January 2009, we need to use the given information and equation, p(t) = 10000e^(rt), where t is the time in years, and r is the growth rate.
Determine the time (t) in years from January 2009 to 2014.
t = 2014 - 2009 = 5 years
Substitute the given population (30,000) and time (5 years) into the equation.
30,000 = 10000e^(5r)
Solve for the growth rate (r).
First, divide both sides by 10000:
3 = e^(5r)
Now, take the natural logarithm of both sides to isolate the exponent:
ln(3) = 5r
Finally, divide both sides by 5:
r = ln(3)/5 ≈ 0.2197
So, the growth rate is approximately 0.2197 per year.
Complete the model with the calculated growth rate.
p(t) = 10000e^(0.2197t)
The growth rate of the city's population is approximately 0.2197 per year, and the completed model for the population is p(t) = 10000e^(0.2197t).

The fifth and tenth terms of an arithmetic sequence,
respectively, are -2 and 53. What is the seventh
term of the sequence?
If the fifth and tenth terms of an arithmetic sequence, respectively, are -2 and 53, the seventh term of the arithmetic sequence is 20.
To find the seventh term of the arithmetic sequence, we need to first find the common difference (d) of the sequence. We know that the fifth term is -2 and the tenth term is 53.
The formula for the nth term of an arithmetic sequence is: an = a1 + (n-1)d
Using this formula, we can set up two equations:
-2 = a1 + 4d (since the fifth term is a1 + 4d)
53 = a1 + 9d (since the tenth term is a1 + 9d)
We now have two equations with two variables (a1 and d). We can solve for either variable using substitution or elimination. I'll use elimination:
-2 = a1 + 4d
53 = a1 + 9d
Subtracting the first equation from the second equation, we get: 55 = 5d
Therefore, d = 11
Now that we know the common difference is 11, we can use the formula for the nth term again to find the seventh term:
a7 = a1 + (7-1)d
a7 = a1 + 6d
We still don't know a1, but we can solve for it using one of the previous equations:
-2 = a1 + 4d
-2 = a1 + 4(11)
-2 = a1 + 44
a1 = -46
Now we can substitute a1 and d into the formula for the seventh term:
a7 = -46 + 6(11)
a7 = -46 + 66
a7 = 20
Therefore, the seventh term of the arithmetic sequence is 20.

To determine the amount of raisins needed for the snack mix, subtract 3 5/12 cups from 5 3/4 cups of cereal.
First, convert the mixed numbers to improper fractions:
5 3/4 = (5 × 4 + 3)/4 = 23/4
3 5/12 = (3 × 12 + 5)/12 = 41/12
Next, subtract the two fractions:
23/4 - 41/12
To subtract, find a common denominator. The least common multiple of 4 and 12 is 12. Convert both fractions to equivalent fractions with a denominator of 12:
(23/4) × (3/3) = 69/12
(41/12) × (1/1) = 41/12
Now, subtract the fractions:
69/12 - 41/12 = 28/12
Finally, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor (4):
28/12 = (28 ÷ 4)/(12 ÷ 4) = 7/3

solve quadratic equation 6x²-11x-35= 0 pls needed urgently
Answer:
Step-by-step explanation:To solve the quadratic equation 6x²-11x-35= 0, we can use the quadratic formula:
x = (-b ± sqrt(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation.
In this case, we have:
a = 6
b = -11
c = -35
Substituting these values into the quadratic formula, we get:
x = (-(-11) ± sqrt((-11)² - 4(6)(-35))) / 2(6)
Simplifying this expression:
x = (11 ± sqrt(121 + 840)) / 12
x = (11 ± sqrt(961)) / 12
x = (11 ± 31) / 12
So, we have two solutions:
x = (11 + 31) / 12 = 3
and
x = (11 - 31) / 12 = -5/2
Therefore, the solutions to the equation 6x²-11x-35= 0 are x = 3 and x = -5/2.

Sum = (-1)^71*1 - (-1)^71*2 + (-1)^71*3 - (-1)^71*4 + ...
= (-1)^71*(1 - 2 + 3 - 4 + ...)
= (-1)^71*(n(n+1)/2)
= 0
Therefore, the sum of the series is 0.
I'd be happy to help you with your question. To determine the convergence or divergence of the series (-1)^71n * n, we can follow these steps:
(i) Since the series has terms that alternate in sign, we can use the Alternating Series Test to test for convergence.
(ii) To apply the Alternating Series Test, we must first verify that the sequence of positive terms is decreasing and has a limit of zero. In this case, the sequence of positive terms is given by "n". As "n" goes to infinity, the sequence increases, not decreases, and the limit is not zero. Therefore, the series (-1)^71n * n does not pass the Alternating Series Test, and it diverges.
(iii) Since the series diverges, it does not have a finite sum.
In conclusion, the given series (-1)^71n * n diverges, and it does not have a finite sum.

Find the height of a cone with a diameter of 12m whose volume is 226m3. Use 3. 14, and round your answer to nearest meter
The height of a cone with a diameter of 12m whose volume is 226m³ is 6 meters.
The formula for the volume of a cone is
V = (1/3) * π * r^2 * h
where V is the volume, r is the radius, h is the height, and π is approximately equal to 3.14.
We know the diameter of the cone is 12m, which means the radius is 6m.
We also know that the volume of the cone is 226m^3.
Substituting these values into the formula, we get:
226 = (1/3) * π * 6^2 * h
Simplifying:
226 = (1/3) * 3.14 * 36 * h
226 = 37.68h
h = 226/37.68
h ≈ 6
Therefore, the height of the cone is approximately 6 meters.

Which of the following tables represent a proportional relationship
a. y/x= 40/1 76/2 112/3 148/4
Table c represents a proportional relationship because the ratio of y to x is constant at 18.
Which table represent a proportional relationship?A proportional relationship is a relationship between two quantities where their ratios always remain the same.
In option (a), the ratio of y to x is not constant. For example, y/x = 40/1 = 40, but y/x = 148/4 = 37. Therefore, this table does not represent a proportional relationship.
In option (b), the ratio of y to x is not constant either. For example, y/x = 48/2 = 24, but y/x = 192/5 = 38.4. Therefore, this table does not represent a proportional relationship.
In option (c), the ratio of y to x is constant. For example, y/x = 18/1 = 18, but y/x = 126/7 = 18. Therefore, this table represent a proportional relationship.

Find the smallest number of terms of the series ∑ n = 1 (-1)^n+1/2^n you need to be certain that the partial sum Sn is within 1/100 of the sum.n=2 n=4 n=6 n=8 n=7
We need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.
We want to find the smallest value of n such that the absolute value of the difference between the sum of the first n terms and the sum of the entire series is less than 1/100.
The sum of the first n terms of the series is given by:
Sn = ∑_(k=1[tex])^n[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]
We can write the sum of the entire series as:
S = ∑_(k=[tex]1)^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex]
The absolute value of the difference between the sum of the first n terms and the sum of the entire series is:
|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] [tex](-1)^(k+1)/2^k|[/tex]
We want to find the smallest value of n such that |S - Sn| < 1/100.
Let's start by evaluating the sum of the series:
S = ∑_(k=1) (-1[tex])^(k+1)[/tex]/[tex]2^k[/tex] = 1/2 - 1/4 + 1/8 - 1/16 + ...
This is a geometric series with first term a = 1/2 and common ratio r = -1/2. The sum of the series is:
S = a/(1-r) = (1/2)/(1+1/2) = 1/3
Now we can write:
|S - Sn| = |∑_(k=n+1[tex])^∞[/tex] (-1[tex])^(k+1)[/tex]/[tex]2^k|[/tex] <= 1/[tex]2^(n+1)[/tex]
The last inequality is true because the terms of the series are decreasing in absolute value, and we are summing an infinite number of terms.
Therefore, we need to find the smallest value of n such that 1/2^(n+1) < 1/100. This gives:
n+1 > log2(100)
n > log2(100) - 1
n > 6.64
The smallest integer value of n that satisfies this inequality is n = 7.
Therefore, we need at least 7 terms of the series to be certain that the partial sum Sn is within 1/100 of the sum.

Ginny made a cylindrical clay vase for her art project. If the vase has a
volume of 672 cubic inches and a diameter of 10 inches, which is closest to
the height of the vase?
If the vase has a volume of 672 cubic inches and a diameter of 10 inches, the height of the cylindrical clay vase is closest to 8.56 inches.
To find the height of the cylindrical vase, we'll use the formula for the volume of a cylinder: V = πr²h, where V is the volume, r is the radius, and h is the height. Given the diameter is 10 inches, the radius (r) is half of that, which is 5 inches. The volume (V) is 672 cubic inches.
Now, we can solve for the height (h) using the formula:
672 = π(5²)h
First, calculate the area of the base (πr²):
π(5²) = 25π
Now, divide the volume by the area of the base to find the height:
h = 672 / 25π
h ≈ 8.56 inches
So, the height of the cylindrical clay vase is closest to 8.56 inches.

It took Franny 5 minutes to walk each lap. The correct option is B.
Franny spent a total of 35 minutes walking around the track and made 7 laps around the track, so the total time for all 7 laps is 35 minutes. Let's assume it took Franny t minutes to walk each lap. Then, we can set up the following equation:
7t = 35
We can solve for t by dividing both sides of the equation by 7:
t = 35/7 = 5
Therefore, the correct option is B.
