The function is growing on this period because the slope is positive.
(y2 - y1)/(x2 - x1) = (2 - 5)/(5 - 2) = (-3)/3 = -1 is the slope of the line section from (2, 5) to (5, 2).
The function is declining on this period because the slope is negative.
(y2 - y1)/(x2 - x1) = (2 - 2)/(7 - 5) = 0/2 = 0 is the slope of the line section from (5, 2) to (7, 2).
The function is neither growing nor declining on this interval because the slope is zero.

if two straight lines intersect each other in such a way that one of the angles formed measures 90 degree show that each of the remaining angles measures 90 degree. Pls tell i need answer till 11 am today
Answer:
\(\large \boxed{\mathrm{view \ explanation}}\)
Step-by-step explanation:
∠BED is measuring 90 degrees (right angle).
The opposite angle of angle ∠BED will also be 90 degrees because of vertical angles.
∠AEC is measuring 90 degrees (right angle).
The angles on a line add up to 180 degrees.
∠AEC and ∠AEB add up to 180 degrees.
90 + ∠AEB = 180
∠AEB = 90
∠AEB is measuring 90 degrees (right angle).
Angles in a circle around the center add up to 360 degrees.
∠BED + ∠AEC + ∠AEB + ∠CED = 360
90 + 90 + 90 + ∠CED = 360
∠CED = 90
∠CED is measuring 90 degrees (right angle).

For the trigonal bipyramidal electron domain geometry, where would the first pair of electrons go? Where would the second pair go? O equatorial; equatorial O equatorial; axial O axial; ; equatorial
O It does not matter where the electron domains go - the geometry will become tetrahedral anyway.
The first pair of electrons go axially. The second pair go equatorially. Hence, the correct answer is axial; equatorial
For the trigonal bipyramidal electron domain geometry, the first pair of electrons will go to the equatorial position because it has less electron-electron repulsion than the axial position. The second pair of electrons will go to the axial position because the axial position has more space and less repulsion from the equatorial pairs.
Six atoms make up the molecular geometry, with one in the middle and the other five forming a triangle pyramid. The atoms on either side of the center have different bond angles. The compounds phosphorus pentachloride and phosphorus pentafluoride are two examples of trigonally bipyramidal molecules.
To reduce electron-electron repulsion, the initial pair of electrons would prefer to occupy one of the axial locations. The axial locations are further apart from each other compared to the equatorial positions, which are closer together. Hence, axial positioning of the initial pair of electrons would provide a shape that is more stable. According to the VSEPR theory, the remaining electron domains (i.e., lone pairs and/or bonded pairs) would be dispersed among the other places once the initial pair of electrons occupy an axial position.

Find two power series solutions of the given differential equation about the ordinary point x = 0. y'' + xy = 0
Answer:
First we write y and its derivatives as power series:
y=∑n=0∞anxn⟹y′=∑n=1∞nanxn−1⟹y′′=∑n=2∞n(n−1)anxn−2
Next, plug into differential equation:
(x+2)y′′+xy′−y=0
(x+2)∑n=2∞n(n−1)anxn−2+x∑n=1∞nanxn−1−∑n=0∞anxn=0
x∑n=2∞n(n−1)anxn−2+2∑n=2∞n(n−1)anxn−2+x∑n=1∞nanxn−1−∑n=0∞anxn=0
Move constants inside of summations:
∑n=2∞x⋅n(n−1)anxn−2+∑n=2∞2⋅n(n−1)anxn−2+∑n=1∞x⋅nanxn−1−∑n=0∞anxn=0
∑n=2∞n(n−1)anxn−1+∑n=2∞2n(n−1)anxn−2+∑n=1∞nanxn−∑n=0∞anxn=0
Change limits so that the exponents for x are the same in each summation:
∑n=1∞(n+1)nan+1xn+∑n=0∞2(n+2)(n+1)an+2xn+∑n=1∞nanxn−∑n=0∞anxn=0
Pull out any terms from sums, so that each sum starts at same lower limit (n=1)
∑n=1∞(n+1)nan+1xn+4a2+∑n=1∞2(n+2)(n+1)an+2xn+∑n=1∞nanxn−a0−∑n=1∞anxn=0
Combine all sums into a single sum:
4a2−a0+∑n=1∞(2(n+2)(n+1)an+2+(n+1)nan+1+(n−1)an)xn=0
Now we must set each coefficient, including constant term =0 :
4a2−a0=0⟹4a2=a0
2(n+2)(n+1)an+2+(n+1)nan+1+(n−1)an=0
We would usually let a0 and a1 be arbitrary constants. Then all other constants can be expressed in terms of these two constants, giving us two linearly independent solutions. However, since a0=4a2 , I’ll choose a1 and a2 as the two arbitrary constants. We can still express all other constants in terms of a1 and/or a2 .
an+2=−(n+1)nan+1+(n−1)an2(n+2)(n+1)
a3=−(2⋅1)a2+0a12(3⋅2)=−16a2=−13!a2
a4=−(3⋅2)a3+1a22(4⋅3)=0=04!a2
a5=−(4⋅3)a4+2a32(5⋅4)=15!a2
a6=−(5⋅4)a5+3a42(6⋅5)=−26!a2
We see a pattern emerging here:
an=(−1)(n+1)n−4n!a2
This can be proven by mathematical induction. In fact, this is true for all n≥0 , except for n=1 , since a1 is an arbitrary constant independent of a0 (and therefore independent of a2 ).
Plugging back into original power series for y , we get:
y=a0+a1x+a2x2+a3x3+a4x4+a5x5+⋯
y=4a2+a1x+a2x2−13!a2x3+04!a2x4+15!a2x5−⋯
y=a1x+a2(4+x2−13!x3+04!x4+15!x5−⋯)
Notice that the expression following constant a2 is =4+ a power series (starting at n=2 ). However, if we had the appropriate x -term, we would have a power series starting at n=0 . Since the other independent solution is simply y1=x, then we can let a1=c1−3c2, a2=c2 , and we get:
y=(c1−3c2)x+c2(4+x2−13!x3+04!x4+15!x5−⋯)
y=c1x+c2(4−3x+x2−13!x3+04!x4+15!x5−⋯)

Three lorries each making five trips per day transport 2500 crates from a factory to a distributor in two days .how many lorries each making 6 trips a day are needed to transport 10000 such crates in a day
Step-by-step explanation:
3×5×2 = 30 lorry trips to deliver 2,500 crates.
3 lorries, 5 trips per day, 2 days
that means that one lorry trip transports
2,500 / 30 = 250/3 = 83.33333... crates = 83 1/3 crates.
now we need x lorries each making 6 trips per day in 1 day (so, 6 trips, period) to transport 10,000 crates.
that looks like
x × 6 × 83.33333... = 10,000
x × 6 × 83 1/3 = 10,000
x × (6×83 + 6 × 1/3) = 10,000
x × (498 + 2) = 10,000
500x = 10,000
x = 20
so, we need 20 lorries each doing 6 trips in one day to transport 10,000 crates in one day.
these are altogether 20×6 = 120 lorry trips.
that is 4 times the number of the original scenario (30 trips).
and logically, when doing 4 times the work, we achieve 4 times the result (10,000 crates instead of 2,500).
The gradient vector of the function - f(x, y) = ln(xy) — x³ at the point (-1, 1) is (-2,-1). Select one: True O False
"The gradient vector of the function - f(x, y) = ln(xy) — x³ at the point (-1, 1) is (-2, -1)" is True.
To find the gradient vector of the function -f(x, y) = ln(xy) - x³, we need to take the partial derivatives of the function with respect to x and y.
Let's find the partial derivatives:
∂/∂x (-f(x, y)) = ∂/∂x (-ln(xy) + x³)
= -∂/∂x (ln(xy)) - ∂/∂x (x³)
To find ∂/∂x (ln(xy)), we can apply the chain rule:
∂/∂x (ln(xy)) = ∂/∂x (ln(x) + ln(y))
= 1/x
And ∂/∂x (x³) = 3x²
Therefore, ∂/∂x (-f(x, y)) = -1/x - 3x²
Now, let's find ∂/∂y (-f(x, y)):
∂/∂y (-f(x, y)) = ∂/∂y (-ln(xy) + x³) = -∂/∂y (ln(xy)) - ∂/∂y (x³)
Using the chain rule again, ∂/∂y (ln(xy)) = ∂/∂y (ln(x) + ln(y)) = 1/y
And ∂/∂y (x³) = 0
Therefore, ∂/∂y (-f(x, y)) = -1/y
At the point (-1, 1), we evaluate the partial derivatives:
∂/∂x (-f(-1, 1)) = -1/(-1) - 3(-1)² = 1 - 3 = -2
∂/∂y (-f(-1, 1)) = -1/1 = -1
So, the gradient vector at the point (-1, 1) is (-2, -1).

at how many points on the interval is the line tangent to parallel to the secant line connecting the function endpoints?
The line tangent to f(x) = x + sin(x) is parallel to the secant line connecting the endpoints at x = π on the interval [-2π, 2π].
Let's begin by finding the slope of the secant line connecting the endpoints of the function. The endpoints of the function on the interval [-2π, 2π] are (-2π, -2π + sin(-2π)) and (2π, 2π + sin(2π)), which evaluate to (-2π, 0) and (2π, 0), respectively.
The slope of the secant line is
m = (0 - 0)/(2π - (-2π)) = 0
Since we want the tangent line to be parallel to the secant line, the slope of the tangent line should also be 0. We can find the equation of the tangent line using the point-slope form
y - (x + sin(x)) = 0
y = x + sin(x)
To find the points on the interval where the tangent line is parallel to the secant line, we need to find the values of x where the derivative of f(x) is equal to 0 (i.e., where the slope of the tangent line is 0). The derivative of f(x) is
f'(x) = 1 + cos(x)
Setting this equal to 0 and solving for x, we get

The indicated limit of the expression (3x - 18)/(x - 9) as x approaches 3 is 1.
To find the limit, we first observe that both the numerator and denominator contain a common factor of (x - 9). By factoring out this common factor, we can rewrite the expression as (3(x - 6))/(x - 9). Now, applying the limit properties, we can evaluate the limit as x approaches 3. As x approaches 3, the term (x - 6) also approaches 3 - 6 = -3.
Therefore, the numerator becomes 3(-3) = -9, and the denominator becomes 3 - 9 = -6. Finally, taking the ratio of -9 and -6 gives us the limit of 1. Thus, the indicated limit is 1.

prove each of the given statements, assuming that a, b, c, d, and n are integers with n > 1 and that a ≡ c (mod n) and b ≡ d (mod n).
a. (a + b) ≡ (c + d) (mod n)
b. (a − b) ≡ (c − d) (mod n)
Since k and l are integers, k + l is also an integer, this proves that (a + b) ≡ (c + d) (mod n).
Since k and l are integers, k − l is also an integer, this proves that (a − b) ≡ (c − d) (mod n)
How to prove (a + b) ≡ (c + d) (mod n)?a. To prove that (a + b) ≡ (c + d) (mod n), we need to show that n divides (a + b) − (c + d), or equivalently, that (a + b) − (c + d) is an integer multiple of n. We have:
(a + b) − (c + d) = a − c + (b − d)
Since a ≡ c (mod n) and b ≡ d (mod n), we can write a = c + kn and b = d + ln for some integers k and l. Substituting these into the above equation, we get:
(a + b) − (c + d) = (c + kn) + (d + ln) − c − d = kn + ln = (k + l)n
Since k and l are integers, k + l is also an integer, and therefore, (a + b) − (c + d) is an integer multiple of n. This proves that (a + b) ≡ (c + d) (mod n).
How to prove (a − b) ≡ (c − d) (mod n)?b. To prove that (a − b) ≡ (c − d) (mod n), we need to show that n divides (a − b) − (c − d), or equivalently, that (a − b) − (c − d) is an integer multiple of n. We have:
(a − b) − (c − d) = a − c − (b − d)
Since a ≡ c (mod n) and b ≡ d (mod n), we can write a = c + kn and b = d + ln for some integers k and l. Substituting these into the above equation, we get:
(a − b) − (c − d) = (c + kn) − (d + ln) − c + d = kn − ln = (k − l)n
Since k and l are integers, k − l is also an integer, and therefore, (a − b) − (c − d) is an integer multiple of n. This proves that (a − b) ≡ (c − d) (mod n).

What are the rational numbers that are not natural or real numbers?
Examples of numbers that are rational number but not natural
-4, -5, 4/5, 0.89, 0.
Rational Numbers:
A type of real number known as a rational number is represented by the formula p/q, where q is not equal to zero. A rational number is any fraction with a non-zero denominator. 1/2, 1/5, 3/4, and other such numbers are a few examples of rational numbers. The number "0" is also a rational number because there are many ways to represent it, including 0/1, 0/2, 0/3, etc. However, since they give us infinite values, 1/0, 2/0, 3/0, etc. are illogical. Check the irrational numbers here as well and contrast them with the rational ones.
Natural Number:
All positive integers from 1 to infinity are included in the number system, which also includes natural numbers, which are also used for counting. There is no zero included (0). In fact, counting numbers are 1, 2, 3, 5, 6, 7, 8, 9, etc.
Real numbers, which only include the positive integers 1, 2, 3, 4,5, and 6, are made up of natural numbers. Negative numbers, fractions, decimals, and zero are not included.
Notably, zero and negative numbers are not considered to be natural numbers.

est the null hypothesis that the mean of the population is 3 against the alternative hypothesis, μ≠3. use α
To test the null hypothesis that the mean of the population is 3 against the alternative hypothesis μ≠3, we can use a hypothesis test with a significance level α.
In hypothesis testing, we compare a sample statistic to a hypothesized population parameter. In this case, we want to determine if the mean of the population is significantly different from 3.
To conduct the test, we first collect a sample of data. Then, we calculate the sample mean and standard deviation.
We use these statistics to calculate the test statistic, which follows a t-distribution with (n-1) degrees of freedom, where n is the sample size.
Next, we determine the critical region based on the significance level α. For a two-tailed test, we divide α by 2 to get the critical values for both tails of the distribution.
Finally, we compare the test statistic to the critical values.
If the test statistic falls within the critical region, we reject the null hypothesis and conclude that the mean of the population is significantly different from 3.
Otherwise, if the test statistic falls outside the critical region, we fail to reject the null hypothesis.

find the average rate of change of over the interval . for how many values of in the interval does the instantaneous rate of change of equal the average rate of change of over that interval?
there are two values of x in the interval where the instantaneous rate of change of is equal to the average rate of change of over the interval.
To find the average rate of change of over the interval , we need to calculate the slope of the line passing through the two endpoints of the interval.
The slope of the line passing through the points and is given by:
( - )/( - ) = ( -3 - 3)/(1 - (-1)) = -6/2 = -3
Therefore, the average rate of change of over the interval is -3.
To find how many values of in the interval have instantaneous rate of change equal to the average rate of change, we need to find the derivative of :
f'(x) = 3x^2 - 3x - 3
Setting f'(x) equal to the average rate of change, we get:
3x^2 - 3x - 3 = -3
Simplifying the equation, we get:
3x^2 - 3x = 0
Factoring out 3x, we get:
3x(x - 1) = 0
Therefore, the solutions are x = 0 and x = 1.
