Using the model, at 150°F they can sell 304 cups.
How many can she expect to sell?We can see that the line that models this passes through (65, 35) and (80, 75)
Then the slope of the line is:
a = (75 - 35)/(80 - 65)
a = 2.66
y = 2.66*x + b
To find the value of b, we can use the fact that y = 35 when x = 65
35 = 2*65 + b
35 - 2*65 = b
-95
y = 2.66*x -95
IF the tempererature is 150°F, then:
y = 2.66*150 - 95
y = 304

A ship leaving dock A has to travel directly to a buoy (represented by point C below) 8.8 miles away. It then may proceed directly to dock B 10.5 miles away. The distance between dock A and dock B is 9.2 miles. What is the measure in degrees of the turn that the ship has to make at the buoy? Round your answer to the nearest tenth of a degree.
Answer:
17.7 degree
Step-by-step explanation:
We can begin by drawing a diagram:
```
C
/|
/ |
/α | 10.5 mi```
A------β------B
\ /
\ /
\/
8.8 mi
```
We can label angles β and α as shown, where β represents the angle from point C to point B and α```
A ------- 9.2 mi -------- B
```
Let's label some angles in the diagram:
- Angle A: the angle between the line from A to C and the line from A to B
- Angle B: the angle between the line from C to A and the line from C to B
- Angle α: the angle at the buoy C
We want to find the measure of angle α. To do that, we can use the law of cosines to find the length of the side opposite angle α:
```
c^2 = a^2 + b^2 - 2ab cos(C)
```
where a = 8.8, b = 10.5, and C = angle B. We can solve for cos(C):
```
cos(C) = (a^2 + b^2 - c^2) / 2ab
```
Since we know a, b, and c (8.8, 10.5, and 9.2 respectively), we can calculate cos(C):
```
cos(C) = (8.8^2 + 10.5^2 - 9.2^2) / (2 * 8.8 * 10.5) ≈ 0.701
```
Now we can find angle B using the inverse cosine function:
```
B = cos^-1(cos(C)) ≈ 45.4°
```
Finally, we can find angle α by subtracting angle A from angle B:
```
α = B - A ≈ 17.7°
```
So the measure of the turn that the ship has to make at the buoy is approximately 17.7 degrees.

Find the quotient and remainder using synthetic division.
x^4-3x^3+9x+6/x+1
The quotient is
The remainder is
Answer:
Step-by-step explanation:
To use synthetic division, we need to set up the coefficients of the dividend polynomial in decreasing order of powers of x, including any missing terms with zero coefficients.
So we have:
Dividend: x^4 - 3x^3 + 9x + 6
Divisor: x + 1
We can represent the divisor as (x + 1) and set up the synthetic division table as follows:
-1 | 1 -3 9 0 6
| -1 4 -13 13
|___________________
| 1 -4 13 -13 19
The numbers on the first row of the table are the coefficients of the dividend polynomial in decreasing order of powers of x. The -1 on the left of the table is the opposite of the divisor, x + 1.
The first number in the second row is always 0, and we get it by bringing down the first coefficient, which is 1. To get the next number in the second row, we multiply the divisor, -1, by 1, and add the result to the second coefficient, which is -3. This gives us -1 x -3 = 3, which we write under -3 in the first row.
We repeat this process for the next numbers in the second row, always multiplying the divisor by the last number in the second row, and adding the result to the next coefficient in the first row. We continue until we reach the last coefficient in the first row.
The last number in the second row, 13, is the remainder of the division. The other numbers in the second row are the coefficients of the quotient polynomial in decreasing order of powers of x. So the quotient is:
x^3 - 4x^2 + 13x - 13
And the remainder is:
13
Therefore, the quotient is x^3 - 4x^2 + 13x - 13, and the remainder is 13.

OORS 15200 In the beginning of BS. 2077, Dolma de posited B? 120,000 in her account at the rate of 9/. p.a. If she paids / of how her fnterest as income tax much total amount did she receive in mae beginning of BS 2080?
Okay, let's break this down step-by-step:
In the beginning of BS 2077, Dolma deposited B? 120,000 in her account.
The interest rate is 9% per annum.
So in the first year (BS 2077), she earned 9% of 120,000 = B? 10,800 in interest.
Her principal amount increased to 120,000 + 10,800 = B? 130,800
In BS 2078, she earned 9% of 130,800 = B? 11,772 in interest.
Her principal now was 130,800 + 11,772 = B? 142,572
In BS 2079, she earned 9% of 142,572 = B? 12,781 in interest.
Her principal now was 142,572 + 12,781 = B? 155,353
In the beginning of BS 2080, her total balance was B? 155,353.
She paid 6% of her interest as income tax.
9% of 155,353 is 13,991.
6% of 13,991 is 839.
So her total interest received in BS 2080 after paying tax was 13,991 - 839 = B? 13,152.
Her total amount received in BS 2080 was:
Principal (155,353) + Interest (13,152) = B? 168,505
So the total amount Dolma received in the beginning of BS 2080 was B? 168,505

what is the end behavior of the function g(x)= -3e^x?
The end behavior of [tex]g(x) = -3e^x[/tex] is As x approaches positive infinity, g(x) approaches negative infinity, As x approaches negative infinity, g(x) approaches 0.
To determine the end behavior of the function g(x) = -3e^x, we need to consider what happens to the output of the function as x gets very large (approaches positive infinity) or very small (approaches negative infinity).
As x approaches positive infinity, e^x also approaches positive infinity, since e is a positive number greater than 1. Therefore, -3e^x approaches negative infinity as x approaches positive infinity. We can write this as:
lim x → ∞ (-3[tex]e^x[/tex]) = -∞
This means that the function g(x) approaches negative infinity as x approaches positive infinity.
Similarly, as x approaches negative infinity, e^x approaches 0, since e to a negative power is equal to 1 divided by e raised to the absolute value of that power. Therefore, -3e^x approaches 0 as x approaches negative infinity. We can write this as:
lim x → -∞ (-3[tex]e^x[/tex]) = 0
This means that the function g(x) approaches 0 as x approaches negative infinity.
So, in summary, the end behavior of g(x) = -3[tex]e^x[/tex] is:
As x approaches positive infinity, g(x) approaches negative infinity.
As x approaches negative infinity, g(x) approaches 0.

Which of the following is a disadvantage of decentralization?
Question content area bottom
Part 1
A.
It allows only the top management to make decisions.
B.
It does not motivate employees because the decision-making powers are not delegated.
C.
It results in problems with achieving goal congruence.
D.
It results in increased customer response time.
Decentralization is a management approach that involves the delegation and assignment of decision-making rights from top levels of management to lower levels of management. Option A
It is an effective way to empower employees and to improve decision-making processes within an organization. The benefits of decentralization include the following:
It empowers more employees at lower levels of management: Decentralization allows employees to take ownership of their work, to be more accountable, and to make decisions that are in the best interest of the organization. This, in turn, leads to improved job satisfaction, employee engagement, and better overall performance.
It allows for better and more timely decision-making: Decentralization ensures that decisions are made closer to where the work is being done. This leads to faster decision-making, improved responsiveness to changes in the market, and better coordination between different departments and teams.
It trains future managers: Decentralization provides employees with the opportunity to gain valuable management experience, which can help prepare them for future leadership roles within the organization.
However, one benefit of decentralization that is not accurate is that it forces top levels of management to focus on individual units. In fact, decentralization can free up top management to focus on the big picture and long-term strategy, rather than getting bogged down in day-to-day operations.
In conclusion, decentralization is a useful management approach that can help organizations improve decision-making, empower employees, and train future managers.
By delegating decision-making rights to lower levels of management, organizations can improve overall performance and become more adaptable to changes in the market.
So Option A is correct.
