Answer:
$110.70
Step-by-step explanation:
I=PRT
P (principal)=360
R(rate)=12.3%
T(time)=30 months (2 and half years)
I=360*12.3%*2.5

Just to note 12.3% is also 0.123 we sometimes change it into a decimal.
The region enclosed by the given curves is rotated about the specified line. State which method you are using (disc, washer, or shell) then set-up the integral to find the volume of the resulting solid. Set-up only, do not integrate.
a. y = 4 – x^2, y = -2x +4, Ux-axis : disc washer shell b. y = 4 – x^2, y = -2x +4, Ux=3: disc washer shell
For part a,
we are rotating the region enclosed by y = 4 – x^2 and y = -2x +4 about the x-axis. We will use the disc, washer, and shell method to find the volume of the resulting solid.
Disc method: We can slice the solid into thin discs perpendicular to the x-axis. The radius of each disc is given by y = 4 – x^2, and the thickness is dx. The volume of each disc is πr^2h, where h = dx and r = 4 – x^2. Thus, the integral for the disc method is:
∫[from -2 to 2] π(4 – x^2)^2 dx
Washer method: We can also slice the solid into thin washers perpendicular to the x-axis. The outer radius of each washer is given by y = 4 – x^2, and the inner radius is given by y = -2x + 4. The thickness is again dx. The volume of each washer is π(R^2 – r^2)h, where h = dx, R = 4 – x^2, and r = -2x + 4. Thus, the integral for the washer method is:
∫[from -2 to 2] π((4 – x^2)^2 – (-2x + 4)^2) dx
Shell method: Alternatively, we can slice the solid into thin vertical shells parallel to the y-axis. The radius of each shell is given by x, and the height is given by y = 4 – x^2 – (-2x + 4) = 6 – x^2 + 2x. The thickness is dy, so the volume of each shell is 2πrh dy, where r = x and h = 6 – x^2 + 2x. Thus, the integral for the shell method is:
∫[from 0 to 4] 2πx(6 – x^2 + 2x) dy
For part b,
we are rotating the same region about the line x = 3. We will use the same methods to find the volume of the resulting solid.
Disc method: The radius of each disc is given by x – 3, and the thickness is dx. The volume of each disc is again πr^2h, where h = dx and r = x – 3. Thus, the integral for the disc method is:
∫[from 1 to 5] π(x – 3)^2 dx
Washer method: The outer radius of each washer is given by y = 4 – x^2 – 3, and the inner radius is given by y = -2x + 4 – 3 = -2x + 1. The thickness is again dx. The volume of each washer is π(R^2 – r^2)h, where h = dx, R = 4 – x^2 – 3, and r = -2x + 1. Thus, the integral for the washer method is:
∫[from 1 to 5] π((4 – x^2 – 3)^2 – (-2x + 1)^2) dx
Shell method: The radius of each shell is given by y + 3, and the height is given by x – (4 – y) = y – x + 4. The thickness is dy, so the volume of each shell is again 2πrh dy, where r = y + 3 and h = y – x + 4. Thus, the integral for the shell method is:
∫[from -2 to 2] 2π(y + 3)(y – x + 4) dy
Note: In part b, we integrate with respect to x instead of y in the disc and washer method, but the limits of integration and the setup are still the same.

y=-(x+3)^2-5
The quadratic function y = -(x + 3)² - 5 is a maximum
What is the maximum or minimum of a function?The maximum or minimum of a function are the maximum or minimum values of the function.
How to determine if the quadratic function is a maximum or minimum?Since we have the quadratic function y = -(x + 3)² - 5, this is the vertex form of a quadratic polynomial.
The vertex form y = a(x - k) + h with vertex (h, k)
So, we have the vertex of the function at (3, -5).
To determine if there is a maximum or a minimum,it will follow these conditions at the vertex
if d²y/dx² > 0 then it is a minimumif d²y/dx² < 0 then it is a maximumSo, differentiating y twice to get d²y/dx², we have
y = -(x + 3)² - 5
dy/dx = d[-(x + 3)² - 5]/dx
= d[-(x + 3)²]/dx - d5/dx
= -2(x + 3) - 0
= -2x - 6
differentiating again, we get d²y/dx². So,
d(dy/dx)/dx = d(-2x - 6)/dx
d²y/dx² = d(-2x)/dx - d6/dx
= -2 - 0
= -2
Since d²y/dx² = -2 < 0. The quadratic function y = -(x + 3)² - 5 is a maximum

A graph shows the horizontal axis numbered 15 to 48. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 30 then a downward trend from 30 to 45.
A graph shows the horizontal axis numbered 12 to 56. The vertical axis is numbered 2 to 8. The graph shows an upward trend from 1 to 32 then a downward trend from 32 to 56.
A graph shows the horizontal axis numbered 15 to 54. The vertical axis is numbered 1 to 5. The graph shows an upward trend from 1 to 24, a downward trend from 24 to 27, an upward trend from 27 to 30, a downward trend from 30 to 39, an upward trend from 39 to 45, a downward trend from 45 to 48, then an upward trend from 48 to 51.
To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.
Looking at the histograms described:
The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.
The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.
The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.
The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.
Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.

The P-value for the hypothesis test H₀: p = 0.9 against H₁: p ≠ 0.9, at α = 0.056, is less than 0.056.
What is hypothesis test?
A hypothesis test is a statistical procedure used to make inferences or draw conclusions about a population based on sample data. It involves formulating two competing hypotheses, the null hypothesis (H₀)
In this hypothesis test, we are interested in determining if the proportion (p) of customers who are satisfied or very satisfied with a corporation's products and services is different from 0.9.
The null hypothesis (H₀) states that the proportion is equal to 0.9, while the alternative hypothesis (H₁) states that the proportion is not equal to 0.9.
To test these hypotheses, we use a binomial proportion test. From the given information, we have a sample of 1000 customers, and 850 of them are satisfied or very satisfied.
Using the sample proportion calculated as 850/1000 = 0.85, we can calculate the test statistic, which follows an approximately standard normal distribution under the null hypothesis.
Since the P-value is less than 0.056, we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of satisfied or very satisfied customers is different from 0.9.

What is the Mark the absolute minimum point of the graph
Answer:
is in the point x = 1, y = -5
Step-by-step explanation:
The absolute minimum of a graph is the point that is the most far below the x-axis.
Such that if we draw a horizontal line parallel to this point, this line should not intersect the graph in another point. It is usually associated with the lowest value of the variable y.
In the graph, we can see that in the extremes we have dots, so the graph does not continue.
Then we can be sure that the absolute minimum is at the bottom of the large curve, that is in the point x = 1, y = -5
Larry made 32 3/4 oz of lemonade in a glass pitcher but he accidently spilled 7/8 oz on the table. How much lemonade is left in the pitcher?
Answer: 31 7/8
Step-by-step explanation:
Firstly, we add the whole part which is 31 into the fraction making it an improper fraction. Then solve the problem by making a common denominator of 3/4 from the whole fraction into 6/8 and adding it to the previous fraction, then subtracting the spilled amount. To make the improper fraction a whole fraction/normal, just divide by the denominator. That's all!
31 x 8 = 248
248 + 6 = 254
254 - 7 = 247
247 ÷ 8 = 31 + \(\frac{7}{8}\)

The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.
Which represents the solution(s) of this system of equations?
(4, 4)
(–4, –12)
(4, 4) and (–4, 12)
(–4, 4) and (4, 12)
Answer:
(4,4)
Step-by-step explanation:
The solution set of the system of equations can be found by setting the two equations equal to each other and solving for x.
x^2 - 6x + 12 = 2x - 4
x^2 - 8x + 16 = 0
(x - 4)^2 = 0
x = 4
Since both equations in the system are equal to y, we can substitute x = 4 into either equation to find the corresponding value of y.
y = 2x - 4 = 2(4) - 4 = 4
Therefore, the solution of this system of equations is (4, 4).
Therefore, the correct answer is (4, 4).
Theresa has a rectangular pool 30 ft long, 15 ft wide, and 4 ft deep. Theresa fills her pool using city water at a rate of $3.95 per 100 gallons of water.
Nancy has a circular pool with a diameter of 24 ft and a depth of 4 ft. Nancy fills her pool with a water delivery service at a rate of $200 per 6000 gallons.
If Theresa and Nancy both fill their pools 6 inches from the top of the pool, determine and state who paid more to fill her pool. [ 1 ft3 water = 7.48 gallons]
Answer:
Step-by-step explanation:
Both pools were filled 6 inches from the top.
12 inches = 1 feet
6 inches = 6/12 = 0.5 foot
Considering Theresa's pool, it is rectangular. The formula for determining the volume if the rectangular pool is
Volume = length × width × height
Height filled is 4 - 0.5 = 3.5 feet
Volume = 30 × 15 × 3.5 = 1575 ft³
Recall, 1 cubic feet = 7.48 Us gallons
Therefore,
1800 cubic feet = 1575 × 7.48 = 11781 gallons of water
Theresa fills her pool using city water at a rate of $3.95 per 100 gallons of water. It means that the amount she paid to fill her pool is
3.95 × 11781/100 = $465.35
Considering Nancy's pool, it is cylindrical. The formula for determining the volume if the cylindrical pool is
Volume = πr²h
Diameter = 24
Radius = diameter/2 = 24/2 = 12 ft
Volume = 3.14 × 12² × 3.5 = 1582.56 ft³. Converting to gallons, it becomes
1582.56 × 7.48 = 11837.55 gallons of water.
Nancy fills her pool with a water delivery service at a rate of $200 per 6000 gallons.
It means that the amount she paid to fill her pool is
200 × 11837.55/6000 = $394.59
Therefore, Theresa paid more to fill her pool.

The required measure of the angle ∠spq of a rhombus is 110°.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
For rhombus,
m∠spr=(2x + 15)°
m∠qpr=(3x−5)°
And,
m∠spr = m∠qpr
2x + 15 = 3x - 5
x = 20
Now,
∠spq = m∠spr + m∠qpr
= 2x + 15 + 3x - 5
= 5x + 10
= 5(20) + 10
= 110°
Thus, the required measure of the angle ∠spq of a rhombus is 110°.
