Mr. Robins earns a commission of 15% on the airfares he books, as he earned $31.29 on $208.60 worth of airfare bookings.
Let x be the amount of commission earned by Mr. Robins on the airfares he booked. Then, we can write the equation:
x = 15% of $208.60
Simplifying this equation, we get:
x = 0.15 x $208.60
x = $31.29
Therefore, Mr. Robins earned a commission of $31.29 on $208.60 worth of airfare bookings. To verify this, we can calculate his commission rate as:
Commission rate = Commission earned / Airfare bookings
Commission rate = $31.29 / $208.60
Commission rate = 0.15 or 15%
Hence, Mr. Robins earns a commission of 15% on the airfares he books.

The equation that can be used to determine the number of people (x) who can go to the amusement park is:
207.50 = 5 + (33.75 × x).
To determine the number of people (x) who can go to the amusement park, we need to create an equation using the given information. We know that they have $207.50 to spend, parking costs $5, and each ticket costs $33.75 per person (including tax).
We can represent the total cost of the trip as the sum of the cost for parking and the cost of the tickets for x number of people. The equation would be:
Total Cost = Cost of Parking + (Cost of Tickets per Person × Number of People)
Since we know the total cost is $207.50, the cost of parking is $5, and the cost of tickets per person is $33.75, we can plug in these values:
207.50 = 5 + (33.75 × x)
This equation can be used to determine the value of the variable x, the number of people who can go to the amusement park. To find the value of x, simply solve the equation by isolating the variable x.

The diameter of om is 68 cm and the diameter of oj is 54 cm. if the length of jk is 8 cm, what is the length of lm? lm
The length of lm is 10 cm.
To find the length of lm, we need to use the fact that om and oj are both diameters of their respective circles. We can start by finding the radius of each circle:
- The radius of om is half of its diameter, so it's 34 cm.
- The radius of oj is half of its diameter, so it's 27 cm.
Next, we can use the fact that jk is perpendicular to lm to create a right triangle:
- One leg of the triangle is jk, which we know is 8 cm.
- The other leg is half of the difference between the radii of the two circles, since lm connects the two circles. That means the other leg is (34 - 27)/2 = 3.5 cm.
Now we can use the Pythagorean theorem to find the length of lm:
lm² = jk² + (radius difference/2)²
lm² = 8² + 3.5²
lm² = 70.25
lm = 10 cm

How might the graph be redrawn to emphasize the difference between the cost per doctor visit for each of the three plans? The scale on the y-axis could be changed to 0–100. The scale on the y-axis could be changed to 25–40. The interval of the y-axis could be changed to count by 5s. The interval of the y-axis could be changed to count by 20s.
To emphasize the difference between the cost per doctor visit for each of the three plans, you can change the scale on the y-axis to either 0–100 or 25–40 and adjust the interval of the y-axis to count by 5s.
To emphasize the difference, you can consider the following adjustments to the graph:
1. Change the scale on the y-axis to 0–100. This adjustment will give a wider range for the costs, making it easier to see the differences between the three plans.
2. Alternatively, change the scale on the y-axis to 25–40. This change will focus more on the specific cost range that the three plans fall into, magnifying the differences between them.
3. Change the interval of the y-axis to count by 5s. This alteration will increase the number of increments on the y-axis, giving a more detailed view of the cost differences between the plans.
4. On the other hand, changing the interval of the y-axis to count by 20s might not be the best option. It will decrease the increments on y-axis and make it harder to visualize the cost differences between the plans.

5. a space shuttle traveling at 17,581 miles per hour decreases its speed by 7,412 miles per hour. estimate the speed of the space shuttle after it has slowed down by rounding each number to the nearest hundred.
The rounding method used, the estimated speed of the space shuttle after it has slowed down is 10,200 miles per hour.
To estimate the speed of the space shuttle after it has slowed down, we round each number to the nearest hundred. The speed before the decrease is rounded to 17,600 miles per hour, and the decrease in speed is rounded to 7,400 miles per hour.
Next, we subtract the rounded decrease in speed from the rounded speed before. So, 17,600 - 7,400 = 10,200 miles per hour. This result represents the estimated speed of the space shuttle after it has slowed down.
Rounding to the nearest hundred is a way to approximate the values and make calculations simpler. However, it is important to note that rounding introduces some degree of error, and the actual speed after the decrease may differ slightly from the estimated value.

Partial sums are:
a) limx→∞ S = L
b) The limit does not exist.
c) limx→∞ S = L
d) The limit does not exist.
We need to use the formulas for partial sums and limits of sequences.
First, recall that the nth partial sum of a series is given by:
Sn = a1 + a2 + ... + an
And the limit of a sequence (if it exists) is given by:
limn→∞ an
Now, let's use these formulas to answer the parts of the question:
a) Find lim S as n approaches infinity:
We have:
S = ax = a1 + a2 + a3 + ... + ax
Taking the limit as x approaches infinity, we get:
limx→∞ S = limx→∞ (a1 + a2 + a3 + ... + ax) = limn→∞ Sn
But we know that the series is convergent, so the limit of the partial sums exists and is equal to the sum of the series:
limn→∞ Sn = L
Therefore:
limx→∞ S = L
b) Find lim as x approaches 0:
We have:
S = ax = a1 + a2 + a3 + ... + ax
Taking the limit as x approaches 0, we get:
limx→0 S = limx→0 (a1 + a2 + a3 + ... + ax)
But as x approaches 0, the number of terms in the sum approaches infinity, so this limit does not exist.
c) Find lim S as x approaches infinity:
We have:
S = ax = a1 + a2 + a3 + ... + ax
Taking the limit as x approaches infinity, we get:
limx→∞ S = limx→∞ (a1 + a2 + a3 + ... + ax) = limn→∞ Sn
Again, we know that the limit of the partial sums exists and is equal to the sum of the series:
limn→∞ Sn = L
Therefore:
limx→∞ S = L
d) Find lim as x approaches 100:
We have:
S = ax = a1 + a2 + a3 + ... + ax
Taking the limit as x approaches 100, we get:
limx→100 S = limx→100 (a1 + a2 + a3 + ... + ax)
But as x approaches 100, the number of terms in the sum approaches infinity, so this limit does not exist.

What is the surface area of the birdhouse?
A. 262 in. 2
B. 576 in. 2
C. 640 in. 2
D. 1,280 in. 2
To find the surface area C of the birdhouse, we need to find the area of each face and add them together.
First, let's find the area of the square base:
Area of base = side^2 = 16^2 = 256 in^2
Next, let's find the area of each triangular face:
Area of each triangular face = 1/2 * base * height
Since the base is 16 in and the slant height is 10 in, the height can be found using the Pythagorean theorem:
height^2 = slant height^2 - base^2/4
height^2 = 10^2 - 16^2/4
height^2 = 100 - 64
height^2 = 36
height = 6
So the area of each triangular face is:
1/2 * 16 * 6 = 48 in^2
There are four triangular faces, so the total area of the triangular faces is:
4 * 48 = 192 in^2
Finally, we add the area of the base and the area of the triangular faces to find the total surface area:
256 + 192 = 448 in^2
Therefore, the surface area of the birdhouse is 448 square inches, which is closest to option A: 262 in^2.

Evaluate the integral.
∫(x^3+4x)/x^4+8x^2+1
To evaluate the integral ∫(x^3+4x)/x^4+8x^2+1, we can use the substitution u = x^2 + 1. Then, du/dx = 2x, which means that dx = du/(2x). Substituting these into the integral, we get:
∫(x^3+4x)/x^4+8x^2+1 dx = ∫(1/u)(x^2+1)(x^3+4x)/(2x) du
= 1/2 ∫(u-1)/u^2 du
= 1/2 ∫(u/u^2 - 1/u^2) du
= 1/2 ln|u| + 1/2 (1/u) + C
= 1/2 ln|x^2+1| + 1/2 (1/(x^2+1)) + C
Therefore, the final answer is ∫(x^3+4x)/x^4+8x^2+1 dx = 1/2 ln|x^2+1| + 1/2 (1/(x^2+1)) + C.
Hi! To evaluate the integral, we can rewrite the given expression as follows:
∫((x^3 + 4x) / (x^4 + 8x^2 + 1)) dx
Now, let's use substitution to solve this integral. Let's set:
u = x^2 + 4
Then, the derivative du/dx = 2x. So, dx = du / (2x).
Now, we can rewrite the integral in terms of u:
∫((x^3 + 4x) / (u^2 + 1)) (du / (2x))
Notice that x^3/x and 4x/x simplify, and we are left with:
(1/2) ∫(u / (u^2 + 1)) du
Now we can integrate this expression:
(1/2) * [ln(u^2 + 1) + C]
Now, substitute back x^2 + 4 for u:
(1/2) * [ln(x^2 + 4 + 1) + C] = (1/2) * [ln(x^2 + 5) + C]
So, the evaluated integral is:
(1/2) * [ln(x^2 + 5) + C]

A globe company currently manufactures a globe that is 18 inches in diameter if the dimensions of the globe are reduced by half what would the volume be 
The volume of the new globe would be 381.51 cubic inches, which is half the volume of the original globe.
The volume of a sphere is given by the formula:
V = (4/3)πr³
where r is the radius of the sphere.
If the diameter of the globe is reduced by half, then the new diameter would be 9 inches, and the new radius would be half of that, or 4.5 inches.
The new volume would be:
V' = (4/3)π(4.5)³
= (4/3)×3.14×(91.125)
= 381.51 cubic inches
Therefore, the volume of the new globe would be 381.51 cubic inches, which is half the volume of the original globe.

Six friends are selling crafts at a flea market. they each need to pay $7. 20 to pay
for the table rental. they each sell 3 items. if every item is the same price, and the
6 friends make a total profit of $25. 20, what was the sale price of each item?
To find the sale price of each item, we need to use some basic algebra. Let's call the sale price of each item "x".
First, we need to find the total cost of the table rental for all six friends. Since each friend needs to pay $7.20, the total cost of the table rental is 6 * $7.20 = $43.20.
Next, we need to find the total revenue from selling the items. Each friend sells 3 items, so the total number of items sold is 6 * 3 = 18. The total revenue is the number of items sold multiplied by the sale price, so the total revenue is 18x.
We know that the total profit is $25.20, which is the total revenue minus the total cost of the table rental. So we can set up the equation:
18x - $43.20 = $25.20
Simplifying this equation, we get:
18x = $68.40
Dividing both sides by 18, we get:
x = $3.80
Therefore, the sale price of each item is $3.80.

The graph shows the height of a scratch on the edge of a circular gear.
Which function is the best model for the height of the scratch?
a. h(t) = 3.5 sin (π t) + 1.5
b. g(t) = 1.5 sin (π t) +3.5
c. h(t) = 1.5 sin (2 π t) + 3.5
d. h(t) = 1.5 sin (π/2 t) + 3.5
Answer:
b. g(t) = 1.5 sin (π t) +3.5
Step-by-step explanation:
You want to choose the function that has the given graph.
Test pointsAt t = 0, the graph shows a value of 3.5. The sine of 0 is 0, so this eliminates choice A.
At t = 1/2, the graph shows a value of 5. The values given by the different formulas are ...
b. g(1/2) = 1.5·sin(π/2) +3.5 = 5 . . . . . matches the graph
c. h(1/2) = 1.5·sin(π) + 3.5 = 3.5 . . . . no match
d. h(1/2) = 1.5·sin(π/4) +3.5 = 0.75√2 +3.5 . . . . no match

Additional comment
The horizontal distance for one period of the graph (from peak to peak, for example) is T = 2 seconds. If the sine function is sin(ωt), then the value of ω is ...
ω = 2π/T = 2π/2 = π
This tells you the function g(t) = 1.5·sin(πt)+3.5 is the correct choice.

$
189. 6. Find the original price
Answer:
274.78
Step-by-step explanation:
Let's call the original price "x".
We know that the price decreased by 31%, so the new price is
100% - 31% = 69% of the original price:
0.69x = 189.6
To solve for x, we can divide both sides by 0.69:
x = 189.6 / 0.69
Simplifying this expression, we get:
x ≈ 274.78
Therefore, the original price was approximately $274.78.
