Answer:
y = 5(x - 3)^2 - 4 + c
Step-by-step explanation:
The standard form of a quadratic function is y = ax^2 + bx + c, where a, b, and c are constants. To shift the graph three units to the right and four units down, we can modify the constant term c and the linear term bx:
y = a(x - 3)^2 - 4 + c
To make it five times narrower, we can modify the coefficient of the squared term a:
y = (1/5)a(x - 3)^2 - 4 + c
Since we want the shape to be the same as y = x^2, we can set a = 5:
y = 5(x - 3)^2 - 4 + c
The value of c will depend on the specific context of the problem or graph.

King Arthur's Sword has a blade that is made of a regular hexagon and a regular pentagon. What is the amplitude of the tip of King Arthur's Sword?
As per the given scenario, the amplitude of the tip of King Arthur's Sword is equal to the length of the side of either the regular hexagon or the regular pentagon.
To decide the amplitude of the tip of King Arthur's Sword, we want to locate the gap from the center of the regular hexagon and pentagon to one in every of their vertices.
A regular hexagon has six identical aspects and 6 same angles. The distance from the center to one of the vertices of a everyday hexagon is identical to the length of its side.
Thus, a everyday pentagon has 5 equal facets and 5 same angles. The distance from the middle to one of the vertices of a everyday pentagon is also equal to the length of its aspect.

For the given confidence level and values of x and n, find the following.
x=45, n=96, confidence level 95%
The confidence interval based on the given values (x = 45, n = 96, Confidence level = 95%.
The confidence level (95%), sample size (n = 96), and sample mean (x = 45), we can calculate the margin of error and the confidence interval. Here's how:
1. Margin of Error:
The margin of error represents the maximum expected difference between the true population parameter and the sample estimate. It depends on the confidence level and the standard deviation (which we don't have in this case).
Since the standard deviation is unknown, we can use the t-distribution to estimate it. With a sample size of n = 96, the degrees of freedom are (n - 1) = 95. Considering a 95% confidence level, the critical value for a two-tailed test is approximately 1.984 (referencing a t-distribution table or calculator).
The margin of error (E) can be calculated using the following formula:
E = critical value * (standard deviation / sqrt(n))
However, since we don't have the standard deviation, we can't compute the margin of error in this case.
2. Confidence Interval:
The confidence interval represents a range of values within which the true population parameter is likely to fall.
The confidence interval can be calculated using the formula:
CI = x ± (critical value * standard deviation / sqrt(n))
The confidence interval based on the given values (x = 45, n = 96, confidence level = 95%.

Use spherical coordinates. Evaluate E x2 + y2 + z2 dV, where E lies above the cone z = x2 + y2 and between the spheres x2 + y2 + z2 = 1 and x2 + y2 + z2 = 64.
Answer:
To solve this problem using spherical coordinates, we need to parameterize the region E using rho, theta, and phi. The cone z = x^2 + y^2 becomes phi = arctan(sqrt(x^2+y^2)/z), and the sphere x^2 + y^2 + z^2 = 1 becomes rho = 1, while x^2 + y^2 + z^2 = 64 becomes rho = 8. Then, we can integrate over the bounds rho = 1 to rho = 8, theta = 0 to theta = 2pi, and phi = 0 to phi = arctan(sqrt(x^2+y^2)/z), using the integrand x^2 + y^2 + z^2. The final result is a numerical value that represents the volume of the region E.

Therefore the 13.2 meters from that point on the ocean floor to the wreck.
AABC has vertices A(-2, 2), B(2, 0), and C(1,-2). For the similarity transformation, find the image of vertex C.
D₂° Ry-axts
Input answer as (x, y)
The image of vertex C under the given similarity transformation is (4, 2).
To apply the given similarity transformation, we need to perform two transformations: a rotation of 90 degrees counterclockwise about the origin (denoted by R) and a dilation by a factor of 2 (denoted by D2). We perform the transformations in order: first the rotation, then the dilation.
The image of a point (x, y) after a rotation of 90 degrees counterclockwise about the origin is (-y, x).
Thus, the image of C after the rotation is:
C' = (-(-2), 1) = (2, 1)
To find the image of C' after the dilation by a factor of 2, we multiply each coordinate by 2:
C" = (22, 21) = (4, 2)
Therefore, the image of vertex C under the given similarity transformation is (4, 2).

How to compare fractions is explained in the solution below.
One way to compare fractions is to convert them into their decimal form and decide which is the smaller of the two.
Example: 7/10 and 3/5 become 0.7 and 0.6.
Hence 3/5 is smaller than 7/10.
The other way is to convert them into fractions with identical denominator.
For that multiply the denominator of one fraction with the numerator and denominator of the other.
Do the same with the other denominator and the other fraction. Then decide which fraction is the smaller of the two.
Example: 7/8 and 13/15 become (7*15)/(8*15) = 105/120 and
(13*8)/(15*8) = 104/120.
Hence 13/15 is smaller than 7/8.

Amit can complete a piece of work in 2.25 days. Badri takes double the time taken by Amit. Chetan
takes double that of Badri, and Das takes double that of Chetan to complete the same task. They are
split into two groups (of one or more persons) such that the difference between the times taken by
the two groups to complete the same work is minimum. What could be the composition of the faster
group?
Answer:
Easy
Step-by-step explanation:
Let the time taken by Badri to complete the work be B. Then Amit can complete the work in 2.25 days, so we can write:
A = 2.25/B
Chetan takes double that of Badri to complete the work, so we can write:
C = 2B
Das takes double that of Chetan to complete the work, so we can write:
D = 2C = 4B
Let the first group consist of Amit and Das, and the second group consist of Badri and Chetan. Then the time taken by the first group to complete the work is:
T1 = A + D = 2.25/B + 4B
The time taken by the second group to complete the work is:
T2 = B + C = B + 2B = 3B
The difference between the times taken by the two groups to complete the work is:
T2 - T1 = 3B - (2.25/B + 4B) = 3B - 2.25/B - 4B
To minimize this difference, we take the derivative with respect to B and set it equal to zero:
d/dB (3B - 2.25/B - 4B) = 0
3 + 2.25/B^2 - 4 = 0
2.25/B^2 = 1
B = sqrt(2.25) = 1.5
Therefore, the time taken by Badri to complete the work is B = 1.5 days. Amit takes 2.25/1.5 = 1.5 days, Chetan takes 2B = 3 days, and Das takes 4B = 6 days.
To minimize the difference between the times taken by the two groups, we can take the faster group to consist of Amit and Badri, and the slower group to consist of Chetan and Das. The faster group takes 1.5 + 1.5 = 3 days to complete the work, and the slower group takes 3 + 6 = 9 days to complete the work. Therefore, the composition of the faster group could be Amit and Badri.

Clarksville City Cafe recently introduced a new flavor of coffee. They served 60 grande cups
and 59 jumbo cups of the new coffee today, which equaled a total of 61,644 grams. The day

How much coffee is required to make each size?
There are 968
grams in a grande cup of coffee and
Submit
grams in a jumbo one.
For this reason, 968 grams of coffee are needed to make a grande cup, and 998 grams are needed to make a jumbo cup.
Let's call the amount of coffee required to make a grande cup "g" and the amount of coffee required to make a jumbo cup "j". We want to find the values of g and j.
From the first piece of information, we know that:
60g + 59j = 61,644
From the second piece of information, we know that:
60g + 74j = 71,184
We can solve this system of equations by using the method of elimination. To eliminate g, we can subtract the first equation from the second equation:
(60g + 74j) - (60g + 59j) = 71,184 - 61,644
Simplifying, we get: 15j = 9540
Dividing by 15, we get: j = 636
Now that we know j, we can substitute it into either equation to find g. Let's use the first equation:
60g + 59(636) = 61,644
Simplifying, we get: 60g = 59,880
Dividing by 60, we get: g = 998
Therefore, the amount of coffee required to make a grande cup is 968 grams, and the amount of coffee required to make a jumbo cup is 998 grams.

If 1, 2, and 4 are three of the digits of the four digit number n, and if n is divisible by 4, find the greatest possible value of n. (40pts) Explain how you know you have the largest possible number n. (60 pts)
Answer: n = 412
Step-by-step explanation:
If the last two digits of a number are divisible by 4, the whole number is divisible by 4 since any multiple of 100 is divisible by 4. The largest number that can be created is 421 since the largest number is in the hundreds place and then the second largest number is in the tens place, but 21 is not divisible by 4. The second largest number, 412, still has the greatest number as the hundreds place, but the tens place is now smaller. 12 is divisible by 4, so 412 is divisible by 4. We know that 412 is the largest possible number for n because there is only one larger number than 412, which is 421 and it is not divisible by 4.
Answer:
The largest possible n is 9412-----------------------------
Divisibility rule for 4:
If the last two digits of a number are divisible by 4, the number is divisible by 4We have 3 digits and the greatest number can be made by these digits is 421. But it has to be divisible by 4, hence we rearrange it to 412. Since 12 is divisible by 4, the number is divisible by 4.
Now, we choose 9 as the fourth digit. It will be a first digit from left and form the largest possible number n:

A customer decides to build a fence around the backyard shown. The fence will not have any gates. The yard is rectangular, with the house being an equal distance from both property lines. As a result, the fence will have five sections. The short sections, connecting to the house, are each 10 feet in length. The yard has a length of 80 feet and a width of 65 feet. How many feet of fencing is needed?
350 feet of fencing is needed to Enclose the backyard
To calculate the amount of fencing needed to enclose the backyard, we need to find the length of the three long sections of the fence.
Since the yard has a width of 65 feet and the two short sections of the fence each measure 10 feet, the total width of the yard plus the short sections of the fence is:
65 + 10 + 10 = 85 feet
Next, we need to find the length of the yard plus the two short sections of the fence. Since the length of the yard is 80 feet, and there are two short sections of the fence that are each 10 feet long, the total length of the yard plus the short sections of the fence is:
80 + 10 + 10 = 100 feet
Now we can calculate the length of the three long sections of the fence by adding up the perimeter of the yard plus the short sections of the fence and then subtracting the lengths of the two short sections of the fence:
2(85 + 100) - 2(10) = 350 feet
