water flows into an empty reservoir at a rate of gal/hour . what is the quantity of water in the reservoir after 9 hours?
Answers
The quantity of water in the reservoir after 9 hours be, 2835 gallons.
Given, water flows into an empty reservoir at a rate of 2800 + 15t gal/hour.
we have to find the quantity of water in the reservoir after 9 hours.
at the rate of 2800 + 15t
put t = 9
So, the quantity of water in the reservoir after 9 hours be,
2800 + 15(9)
2800 + 135
= 2835
So, the quantity of water in the reservoir after 9 hours be, 2835 gallons.
Hence, the quantity of water in the reservoir after 9 hours be, 2835 gallons.

if f(1) = 12, f ' is continuous, and 6 f '(x) dx 1 = 16, what is the value of f(6)
Answers
To find the value of f(6), we can use the information given about the function f(x) and its derivative f'(x).The value of f(6) is 44/3.
Given that f'(x) is continuous, we can apply the Fundamental Theorem of Calculus. According to the theorem:
∫[a to b] f '(x) dx = f(b) - f(a)
In this case, we are given that:
∫[1 to 6] 6 f '(x) dx = 16
We can simplify the integral:
6 ∫[1 to 6] f '(x) dx = 16
Since f'(x) is the derivative of f(x), the integral of 6 f '(x) dx is equal to 6 f(x). Therefore, we have:
6 f(6) - 6 f(1) = 16
Substituting the given value f(1) = 12:
6 f(6) - 6(12) = 16
6 f(6) - 72 = 16
Next, we isolate the term with f(6):
6 f(6) = 16 + 72
6 f(6) = 88
Finally, we solve for f(6) by dividing both sides by 6:
f(6) = 88 / 6
f(6) = 44/3

For each plumbing repair job, Mr. Wrench charges $N$ dollars for coming out to the house plus $x$ dollars per hour that he works at the house. He charged $\$97$ for a one-hour repair job and $\$265$ for a five-hour repair job. What is his charge for a two-hour repair job
Answers
Mr. Wrench would charge $139 for a two-hour repair job for coming out to the house as N dollars and the charge per hour of work as x dollars.
Let's denote the charge for coming out to the house as N dollars and the charge per hour of work as x dollars. We are given the following information:
For a one-hour repair job, the total charge is $97.
For a five-hour repair job, the total charge is $265.
From this, we can set up two equations:
N + 1x = 97 (equation 1)
N + 5x = 265 (equation 2)
To find the charge for a two-hour repair job, we need to solve for N and x in the equations above and substitute the value of x into the equation for a two-hour repair job.
Subtracting equation 1 from equation 2, we get:
(5x - 1x) = (265 - 97)
4x = 168
x = 42
Now we can substitute the value of x into equation 1 to solve for N:
N + 1(42) = 97
N + 42 = 97
N = 97 - 42
N = 55
Therefore, the charge for a two-hour repair job is N + 2x:
55 + 2(42) = 55 + 84
= $139

Given Numbers:{ 1,2,3,4,5,6,7,8,9,10}
We have to find the probability that the positive difference between the numbers selected is 3 or greater.
Probability is the likelihood of happening an event among all the events possible.
Total number of combinations when two numbers are selected from 10 numbers is 10 C 2=10!/2!(10-2)!

Question text Level and Trend in a Time Series is estimated by- Select one: a. Moving Average b. Simulation method c. Regression analysis d. Covariance analysis e. Correlation Analysis
Answers
(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.
Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.
Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.
The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.
While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

What evidence is needed to prove two triangles are similar by the SSS similarity theorem?
Answers
Consider the same figure as given above. It is observed that DP/PE = DQ/QF and also in the triangle DEF, the line PQ is parallel to the line EF.
So, ∠P = ∠E and ∠Q = ∠F.
Hence, we can write: DP/DE = DQ/DF= PQ/EF.
The above expression is written as
DP/DE = DQ/DF=BC/EF.
It means that PQ = BC.
Hence, the triangle ABC is congruent to the triangle DPQ.
(i.e) ∆ ABC ≅ ∆ DPQ.
Thus, by using the AAA criterion for similarity of the triangle, we can say that
∠A = ∠D, ∠B = ∠E and ∠C = ∠F.

find an equation for the plane that contains the line =(−1,1,2) (3,2,4) and is perpendicular to the plane 2 −3 4=0
Answers
The equation of the plane is:2x - 3y + 4z = 2.
Let's consider a line with the equation:(-1, 1, 2) + t(3, 0, -3), 0 ≤ t ≤ 1. The direction vector of this line is (3, 0, -3).
We must first find the normal vector to the plane that is perpendicular to the given plane.
The equation of the given plane is 2 - 3 + 4 = 0, which means the normal vector is (2, -3, 4).
As the required plane is perpendicular to the given plane, its normal vector must be parallel to the given plane's normal vector.
Therefore, the normal vector to the required plane is (2, -3, 4).
We will use the point (-1, 1,2) on the line to find the equation of the plane. Now, we have a point (-1, 1,2) and a normal vector (2, -3, 4).
The equation of the plane is given by the formula: ax + by + cz = d Where a, b, c are the components of the normal vector (2, -3, 4), and x, y, z are the coordinates of any point (x, y, z) on the plane.
Then we have,2x - 3y + 4z = d.
Now, we must find the value of d by plugging in the coordinates of the point (-1, 1,2).
2(-1) - 3(1) + 4(2) = d
-2 - 3 + 8 = d
d = 2
Therefore, the equation of the plane is:2x - 3y + 4z = 2

3 / 20 + 4√2 can't be a possible answer because adding a fraction with a radical expression doesn't involve rationalizing the denominator and Option B is incorrect since it doesn't have the proper form.
Given the fraction,
5−24, we are supposed to rationalize the denominator. The process of rationalizing the denominator is to remove any radicals in the denominator by multiplying both numerator and denominator by the conjugate of the denominator. For instance, the conjugate of √2 + 4 is √2 - 4.
Let's start by putting the given expression over a common denominator:
5−2424 = (5 * 4) / (2 * 4) - 2 / 4
= 20 / 8 - 2 / 4
Now, let's combine the two fractions. For this, we need to have a common denominator:
20 / 8 - 2 / 4 = (20 - 4) / 8
= 16 / 8
This reduces to:
16 / 8 = 2
Therefore, the simplified expression is 2. Thus, Option D is the correct answer.
3 / 20 + 4√2 can't be a possible answer because adding a fraction with a radical expression doesn't involve rationalizing the denominator and Option B is incorrect since it doesn't have the proper form.

The graph of a function can be used to find solutions to equations and to identify important properties of the function, such as its domain, range, intercepts, and asymptotes.
The set of points (x,y) in the xy-plane that satisfy the equation of a function defined by an equation in xx and yy is called the graph of the function. Graphing an equation allows one to identify patterns in the data and draw conclusions about the relationship between variables. The graph of a function is created by plotting points (x,y) on the coordinate plane and connecting them with a line or curve.
Each point on the graph represents a pair of inputs and outputs that satisfy the equation of the function. The graph provides a visual representation of the behavior of the function over a given domain.
For example, consider the function f(x) = x^2. The graph of this function is a parabola that opens upwards, as shown below:graph of function f(x) = x^2The input values are represented by the x-coordinates on the graph, and the output values are represented by the y-coordinates.
