Answers
The pairs of cities that will not put Jenny back under budget if she drops them are:
a. Moscow and Chelyabinsk
b. Izhevsk and Nizhny Novgorod
To determine which pair of cities Jenny can drop without going over budget, we need to find the total cost of each pair and see if it exceeds her budget of rub 33,000.
a. Moscow and Chelyabinsk:
Total cost = 5,485 + 5,217 = 10,702 rubles
This pair of cities is over budget, so Jenny cannot drop any other cities if she wants to visit both Moscow and Chelyabinsk.
b. Izhevsk and Nizhny Novgorod:
Total cost = 4,721 + 6,920 = 11,641 rubles
This pair of cities is over budget, so Jenny cannot drop any other cities if she wants to visit both Izhevsk and Nizhny Novgorod.
c. Novosibirsk and Saint Petersburg:
Total cost = 4,870 + 5,960 = 10,830 rubles
This pair of cities is under budget, so Jenny can drop this pair without going over budget.
d. Yaroslavl and Tolyatti:
Total cost = 4,901 + 5,598 = 10,499 rubles
This pair of cities is under budget, so Jenny can drop this pair without going over budget.

and BD⎯⎯⎯⎯⎯
as E. Using the Perpendicular Bisector Theorem, determine how far it is from third base to home plate. Describe your conclusion in the context of the situation
Answers
Using the Perpendicular Bisector Theorem, the distance from third base to home plate is 90 feet. This means that all the bases are equidistant from home plate, which is a fundamental property of a baseball diamond.
To find the distance from third base to home plate, we need to use the Perpendicular Bisector Theorem, which states that if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment.
First, we draw a baseball diamond with points A, B, C, and D labeled as described in the problem.
Next, we draw the line segment that joins first base (B) and third base (D), and we construct the perpendicular bisector of this segment by drawing a line through the midpoint of BD and perpendicular to BD. Let's label the point where the perpendicular bisector intersects the line that connects home plate (A) and second base (C) as E.
Since E lies on the perpendicular bisector of BD, it is equidistant from B and D. We know that first base (B) is 90 feet from home plate (A), so the distance from home plate to E must also be 90 feet. Therefore, the distance from third base (D) to home plate (A) is also 90 feet.
In conclusion, using the Perpendicular Bisector Theorem, we determined that the distance from third base to home plate is 90 feet.

What is the probability of Occurrence?The probability of an event is defined as a number that describes the chance that the event will eventually happen. An event that is sure to happen has a probability of 1. An event that can never possibly happen has a probability of zero. Finally, If there is a chance that an event will happen, then it will have a probability that is between zero and 1.
i) Arrow lands on a section labeled with an odd number: The odd numbers here are 1 and 3.
There are a total of four 1's, and two 3's. This tells us that there are 6 odd numbers on the spinner.
There are 8 numbers in total on the spinner. Thus, 6 out of the 8 numbers are seen as odd numbers. Therefore, the probability that the arrow lands on an odd number would be:
P(odd number) = 6/8 = 75%
ii) Arrow lands on a section labeled with the number 1: There are four 1's on the spinner, and there are seen to be 8 numbers in total on the spinner. Thus, the probability of the arrow landing on a 1 is:
P(Number 1) = 4/8 = 50%.

ansley’s age is 5 years younger than 3 times her cousin’s age. ansley is 31 years old.
let c represent ansley’s cousin’s age. what expression, using c, represents ansley’s age?
enter your response in the box.
Answers
Ansley's cousin is 12 years old, and Ansley's age can be found by plugging in 12 for Cousin's age.
How can we know that Ansley's age is 5 years less than 3 times her cousin's age?The problem tells us that Ansley's age is 5 years less than 3 times her cousin's age. We can write this as an equation:
Ansley's age = 3 × Cousin's age - 5
We also know that Ansley is 31 years old. So we can substitute 31 for Ansley's age in the equation:
31 = 3 × Cousin's age - 5
Now we solve for Cousin's age. First, we add 5 to both sides of the equation:
31 + 5 = 3 × Cousin's age
Simplifying:
36 = 3 × Cousin's age
Finally, we divide both sides by 3:
Cousin's age = 12
So Ansley's cousin is 12 years old, and Ansley's age can be found by plugging in 12 for Cousin's age in the expression we found earlier:
Ansley's age = 3 × Cousin's age - 5 = 3 × 12 - 5 = 31
So Ansley is indeed 31 years old.

To find how many more miles she jogged in the first week, we need to subtract the distance she jogged in the second week from the distance she jogged in the first week:
10 3/16 miles - 8 7/16 miles
We need to first convert both mixed numbers to improper fractions:
10 3/16 = (10 x 16 + 3) / 16 = 163 / 16
8 7/16 = (8 x 16 + 7) / 16 = 135 / 16
Now we can subtract the two fractions:
163 / 16 - 135 / 16 = (163 - 135) / 16 = 28 / 16
We can simplify the fraction by dividing both the numerator and the denominator by their greatest common factor (GCF), which is 4:
28 / 16 = (4 x 7) / (4 x 4) = 7 / 4

The base of a right octagonal prism has eight sides equal in length. One side of the base measures 2. 3 cm, and the area of the base is 25. 76 cm². The surface area of the prism is 223. 56 cm².
Whats the height of the prism?
Answers
The height of the right octagonal prism is approximately 10.75 cm.
The given information states that the base of the prism is a regular octagon with each side measuring 2.3 cm, and the area of the base is 25.76 cm². Additionally, the surface area of the prism is 223.56 cm².
First, let's calculate the area of the eight lateral faces. We can do this by subtracting the base's area from the total surface area:
223.56 cm² (total surface area) - 25.76 cm² (base area) = 197.8 cm² (lateral area)
Now, we know that the lateral area is the sum of the areas of all eight rectangular faces. Each rectangle has a base of 2.3 cm (the same as the sides of the octagonal base) and a height equal to the height of the prism (h). Since there are eight faces, the combined area of these rectangles is 8 x 2.3 x h:
8 x 2.3 x h = 197.8 cm²
18.4 x h = 197.8 cm²
To find the height of the prism (h), we can divide both sides of the equation by 18.4:
h = 197.8 cm² / 18.4
h ≈ 10.75 cm
So, the height of the right octagonal prism is approximately 10.75 cm.

The effect on the median of the players' heights cannot be determined. B. The median of the players' heights is decreased. C. The median of the players' heights is increased. D. The median of the players' heights is not affected
Answers
Answer: The median of the players' heights is not affected.
Step-by-step explanation: B
The median of the players' heights is increased.
we need to consider the current arrangement of heights and the positions
of the new players in relation to the existing players' heights.
If we assume that the heights of the players are sorted in ascending order,
adding two additional players can affect the median in the following ways:
If both new players have heights lower than the current median:
In this case, adding the new players would not change the median.
The median would remain the same because the new players would be
added below the existing median, and the position of the median would
not shift.
If one new player has a height lower than the current median and the other
has a height higher than the current median:
In this case, the median would be increased.
Adding a taller player would shift the median towards the higher end of the data set.
If both new players have heights higher than the current median:
In this case, the would be increased.
Both new players would be taller than the current median, causing the
median to shift towards the higher end of the data set.

A. 1
B. 1/4
C. 1/2
D. -1/2
Answers
The answer is A. 1. We can use L'Hopital's rule to evaluate the limit:
limit x→9√(f(x))-3/√(x)-3 = limit x→9 (f(x)-9)/(x-9) / (√(f(x))-3)/(√(x)-3)
Now, we know that f(9) = 9 and f'(9) = 4, so we can use the definition of the derivative to write:
f(x) - f(9) = f'(9)(x-9) + o(x-9)
where o(x-9) represents a term that goes to 0 faster than x-9 as x approaches 9. Plugging this into the numerator, we get:
f(x) - 9 = 4(x-9) + o(x-9)
Plugging this into the denominator, we get:
√(f(x)) - 3 = √(4(x-9) + o(x-9)) = 2√(x-9) + o(1)
√(x) - 3 = √(x-9) + o(1)
Therefore, the limit becomes:
limit x→9 (4(x-9) + o(x-9))/(√(x-9) + o(1)) / (2√(x-9) + o(1))/(√(x-9) + o(1))
Simplifying this expression, we get:
limit x→9 2(4(x-9) + o(x-9))/(√(x-9) + o(1))^2
limit x→9 8 + 2o(1)/(x-9)
As x approaches 9, the o(1) term goes to 0, so the limit becomes:

Alan buys a bag of cookies that contains 5 chocolate chip cookies, 5 peanut butter cookies, 5 sugar cookies and 9 oatmeal cookies. What is the probability that Alan randomly selects a chocolate chip cookie from the bag, eats it, then randomly selects a peanut butter cookie? Express you answer as a reduced fraction
Answers
To find the probability of both events happening, we multiply the probabilities:
P(select chocolate chip then peanut butter) = P(select chocolate chip) × P(select peanut butter after selecting chocolate chip)
= (5/24) × (5/23)
We can reduce this fraction by finding the greatest common factor of the numerator and denominator, which is 1 in this case:
P(select chocolate chip then peanut butter) = (5/24) × (5/23) = 25/1104
Therefore, the probability that Alan randomly selects a chocolate chip cookie from the bag, eats it, then randomly selects a peanut butter cookie is 25/1104.

if you roll two fair six-sided dice, what is the probability that the sum is 4 44 or higher?
Answers
The probability of rolling two fair six-sided dice and getting a sum of 4 or higher is 11/12
To calculate the probability of rolling two fair six-sided dice and getting a sum of 4 or higher, we first need to calculate the total number of possible outcomes.
The number of possible outcomes when rolling two dice is 6 × 6 = 36, since each die has 6 possible outcomes.
Now, let's find the number of outcomes that result in a sum of 4 or higher. We can do this by listing all the possible outcomes:
Sum of 4: (1, 3), (2, 2), (3, 1) = 3 outcomes
Sum of 5: (1, 4), (2, 3), (3, 2), (4, 1) = 4 outcomes
Sum of 6: (1, 5), (2, 4), (3, 3), (4, 2), (5, 1) = 5 outcomes
Sum of 7: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1) = 6 outcomes
Sum of 8: (2, 6), (3, 5), (4, 4), (5, 3), (6, 2) = 5 outcomes
Sum of 9: (3, 6), (4, 5), (5, 4), (6, 3) = 4 outcomes
Sum of 10: (4, 6), (5, 5), (6, 4) = 3 outcomes
Sum of 11: (5, 6), (6, 5) = 2 outcomes
Sum of 12: (6, 6) = 1 outcome
Therefore, the number of outcomes that result in a sum of 4 or higher is 3 + 4 + 5 + 6 + 5 + 4 + 3 + 2 + 1 = 33.
Therefore, the probability of rolling two fair six-sided dice and getting a sum of 4 or higher is 33/36 = 11/12.
To find the probability of getting a sum of 44 or higher, we need to subtract the probability of getting a sum of 43 or lower from 1:
Sum of 2: (1, 1) = 1 outcome
Sum of 3: (1, 2), (2, 1) = 2 outcomes
Sum of 4: (1, 3), (2, 2), (3, 1) = 3 outcomes
Sum of 5: (1, 4), (2, 3), (3, 2), (4, 1) = 4 outcomes
Sum of 6: (1, 5), (2, 4), (3, 3), (4, 2), (5, 1) = 5 outcomes

A survey of 61 randomly selected homeowners finds that they spend a mean of $62 per month on home maintenance. construct a 98% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners. assume that the population standard deviation is $13 per month. round to the nearest cent.
Answers
The 98% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners is $58.06 to $65.94.
To construct a confidence interval for the mean amount of money spent per month on home maintenance by all homeowners, we can use the formula:
CI = [tex]\bar{X}[/tex] ± Zα/2 * (σ/√n)
where [tex]\bar{X}[/tex] is the sample mean, Zα/2 is the critical value from the standard normal distribution corresponding to the desired confidence level, σ is the population standard deviation, and n is the sample size.
In this case, we have:
[tex]\bar{X}[/tex] = $62 (the sample mean)
α = 0.02 (since we want a 98% confidence interval, which means α/2 = 0.01)
Zα/2 = 2.33 (from the standard normal distribution table)
σ = $13 (the population standard deviation)
n = 61 (the sample size)
Substituting these values into the formula, we get:
CI = $62 ± 2.33 * ($13/√61)
Simplifying this expression, we get:
CI = $62 ± $3.94
Therefore, the 98% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners is $58.06 to $65.94.
This means that we can be 98% confident that the true population mean falls within this range. In other words, if we were to repeat the survey many times and construct confidence intervals in the same way, about 98% of the intervals would contain the true population mean.
It's important to note that this assumes that the sample is representative of the population, and that the population standard deviation is known. If these assumptions are not met, then the confidence interval may not be accurate.

How to find x and y21. When line m and line n are parallel then using corresponding angle theorem we have that:
7y - 23 + 8x - 21 = 180
7y - 8x = 180 + 23 - 21
7x - 8x = 182
Also
8x - 21 + 23x - 16 = 180
8x + 23x = 180 + 21 + 16
31x = 217
x = 217 / 31
x = 7
using vertical angle theorem we have:
7y - 23 = 23x - 16
plugging in the value of x
7y - 23 = 23 * 7 - 16
7y - 23 = 145
7y = 145 + 23

A rectangular patio is 10 feet by 13 feet. what is the length of the diagonal of the patio? (use pythagorean theorem: a² + b ²= c²)
Answers
The length of the diagonal is c = √269 feet.
To get the length of the diagonal of a rectangular patio, we can use the Pythagorean theorem, which states that for a right triangle with legs of length a and b, and hypotenuse of length c, a² + b² = c². In this case, the legs of the right triangle are the length and width of the rectangular patio, which are 10 feet and 13 feet, respectively. Let's use a and b to represent these lengths.
a = 10 feet
b = 13 feet
We want to find the length of the diagonal, which is the hypotenuse of the right triangle. Let's use c to represent this length.
a² + b² = c²
10² + 13² = c²
100 + 169 = c²
269 = c²
Now we need to find the square root of 269 to get the length of the diagonal.
c = √269
c ≈ 16.4 feet
So the length of the diagonal of the rectangular patio is approximately 16.4 feet. We can also find the ratio of the length, width, and diagonal of the rectangular patio.
length:width = 10:13
width:length = 13:10
length:diagonal = 10:√269
width:diagonal = 13:√269
diagonal:length = √269:10
diagonal:width = √269:13

Farha Gadhia has applied for a $100,000 mortgage loan
at an annual interest rate of 6%. The loan is for a period of 30 years
and will be paid in equal monthly payments that include interest.
Use the monthly payment formula to find the payment.
Answers
M = P * (r/12) * (1 + r/12)^n / ((1 + r/12)^n - 1)
where:
M is the monthly payment
P is the principal amount (the amount of the loan)
r is the annual interest rate (as a decimal)
n is the total number of payments (number of years multiplied by 12)
In this case, we have:
P = $100,000
r = 0.06 (6% expressed as a decimal)
n = 30 years * 12 months/year = 360
Substituting these values into the formula, we get:
M = 100000 * (0.06/12) * (1 + 0.06/12)^360 / ((1 + 0.06/12)^360 - 1)
Simplifying this expression, we get:
M = $599.55 (rounded to the nearest cent)
Therefore, Farha's monthly mortgage payment will be $599.55, which includes both principal and interest.

FILL IN THE BLANK. Find the indefinite integral ∫ sin²(x)- cos²(x)/cos(x) dx =_______ Note: Use an upper-case "C" for the constant of integration.
Answers
The final result is ∫ sin²(x)- cos²(x)/cos(x) dx = -3cos²(x)/2 + 2ln|cos(x)| + C.
To solve the indefinite integral ∫ sin²(x)- cos²(x)/cos(x) dx, we need to use trigonometric identities to simplify the integrand.
First, we use the identity sin²(x) + cos²(x) = 1 to write:
sin²(x) - cos²(x) = sin²(x) + cos²(x) - 2cos²(x) = 2sin²(x) - cos²(x)
Next, we use the identity sin²(x) = 1 - cos²(x) to write:
2sin²(x) - cos²(x) = 2(1-cos²(x)) - cos²(x) = 2 - 3cos²(x)
Substituting this into the original integral, we get:
∫ sin²(x)- cos²(x)/cos(x) dx = ∫ (2 - 3cos²(x))/cos(x) dx
Now, we use the substitution u = cos(x) and du/dx = -sin(x) dx to transform the integral into a simpler form:
∫ (2 - 3cos²(x))/cos(x) dx = ∫ (2 - 3u²)/u (-du/sin(x))
= -∫ (3u² - 2)/u du
= -3∫ u du + 2∫ du/u
= -3u²/2 + 2ln|u| + C
= -3cos²(x)/2 + 2ln|cos(x)| + C
where C is the constant of integration.
Substituting back u = cos(x), we obtain the final result
∫ sin²(x)- cos²(x)/cos(x) dx = -3cos²(x)/2 + 2ln|cos(x)| + C

How to get the centre of the circle when the circumference is not given
Answers
To find the center of a circle when the circumference is not given, you still find it.
1. Determine the coordinates of at least three non-collinear points on the circle. Non-collinear points are points that do not lie on a straight line.
2. Using these points, create two line segments that are chords of the circle. A chord is a line segment connecting two points on the circle.
3. Find the midpoints of each chord. The midpoint formula is given as: Midpoint (M) = ((x1 + x2) / 2, (y1 + y2) / 2).
4. Calculate the slope of each chord using the slope formula: Slope (m) = (y2 - y1) / (x2 - x1).
5. Calculate the slope of the perpendicular bisectors of each chord. Since these lines are perpendicular to the chords, their slopes are the negative reciprocal of the chord slopes: m_perpendicular = -1 / m_chord.
6. Write the equation of each perpendicular bisector using the point-slope formula: y - y_midpoint = m_perpendicular * (x - x_midpoint).
7. Solve the system of equations formed by the two perpendicular bisectors. The solution is the coordinates of the center of the circle.
By following these steps, you can find the center of the circle even when the circumference is not given.

Garden plots in the Portland Community Garden are rectangles
limited to 45 square meters. Christopher and his friends want a plot
that has a width of 7.5 meters. What length will give a plot that has
the maximum area allowed?
Answers
The length should be less than or equal to 6 meters in order to have a plot with the maximum area allowed (45 square meters) when the width is 7.5 meters.
To find the length that will give a plot with the maximum area allowed, we can use the formula for the area of a rectangle:
Area = Length × Width
The width is given as 7.5 meters, and the area should not exceed 45 square meters.
Let's denote the length as L.
We want to maximize the area, so we need to find the value of L that satisfies the condition Area ≤ 45 and gives the largest possible area.
Substituting the given values into the area formula, we have:
Area = L × 7.5
Since the area should not exceed 45 square meters, we can write the inequality:
L × 7.5 ≤ 45
To find the maximum value of L, we can divide both sides of the inequality by 7.5:
L ≤ 45 / 7.5
Simplifying the right side:
L ≤ 6
Therefore, the length should be less than or equal to 6 meters in order to have a plot with the maximum area allowed (45 square meters) when the width is 7.5 meters.
