Answers
Answer:
I would rate my feelings 4 on a scale of 5
Step-by-step explanation:
Before exercising I usually feel low and heavily laden with overwhelming thoughts and the feeling doesn't seem to leave except in engage in some form of activities that will take my time and consciousness of time.
Like exercising does take time and it's very engaging one wouldn't know the passage of time while doing some physical task.
It's always relaxing after engaging in physical exercise,I also see it as physical therapy for mental health.

Write an equivalent equation to AB = AC using A^-1 such that, when it is simplified, the resulting equation will simplify to B = C. What property should be used to continue simplifying the above equation? A. (AB)^-1 = B^-1A^-1 B. (A^-1)^T = (A^T)^-1 C. A-^1A = 1 D. (A^-1)^-1 = A
Answers
The property that should be used to continue simplifying the above equation is A-^1A = 1. So, correct option is C.
We can start with the equation AB = AC and multiply both sides by A^-1 on the left:
A^-1(AB) = A^-1(AC)
Using the associative property of matrix multiplication, we can simplify the left-hand side:
(A^-1A)B = (A^-1A)C
Using the fact that A^-1A = I (the identity matrix), we get:
IB = IC
Simplifying further using the fact that I times any matrix is that matrix itself, we obtain:
B = C
Therefore, the equivalent equation to AB = AC using A^-1 that simplifies to B = C is A^-1(AB) = A^-1(AC), and the property used to continue simplifying the equation is A^-1A = I.
The correct option is (C) A^-1A = 1, which is equivalent to A^-1A = I, since the identity matrix is denoted as 1 in some contexts.

Evaluate ∫ ∫ (x² + y²)dx dy over the region in the positive quadrant which x+y≤1.
Answers
The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.
To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.
Now, integrating the inner integral with respect to x, we get:
∫ (x² + y²)dx = (1/3)x³ + y²x + C1,
where C1 is the constant of integration.
Next, we integrate the resulting expression with respect to y:
∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,
where C2 is another constant of integration.
Finally, we evaluate this double integral over the given region by substituting the limits of integration:
∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.
Performing the integration, we can find the numerical value of the double integral within the given region.

suppose that the distribution for total amounts spent by students vacationing for a week in florida is normally distributed with a mean of 650 and a standard deviation of 120 . suppose you take a simple random sample (srs) of 10 students from this distribution. what is the probability that a srs of 10 students will spend an average of between 600 and 700 dollars? round to five decimal places.
Answers
The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is 0.8132.
Let x be the total amount spent by students.
x follows normal distribution with mean μ = 650,
standard deviation δ = 120
We take a simple random sample of size n = 10
We are asked to find average spending of 10 students ( \(x\) ) is between 600 and 700
We have to find P( 600 <= \(x\) <= 700)
According to the sampling distribution of the sample mean \(x\), it follows an approximately normal distribution with mean μ{\(x\)} = μ and standard deviation δ{\(x\)} = {δ}/{√n}
Therefore here mean of \(x\),( μ{\(x\)} ) = 650 and
standard deviation of \(x\), δ{\(x\)} = {120}/{√10} = 37.9473
The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is,
Let Z= x - μ / δ
Z₁ = 600 - 650 / 37.9473 = -1.32 similarly
Z₂ = 700 - 650 / 37.9473 = 1.32
From standard normal distribution table, P( -1.32 < \(x\) < 1.32) = 0.8132
The probability that the SRS of 10 students will spend an average of between 600 and 700 dollars is 0.8132

Solve for the remaining sides and angles if possible (if not, answer "DNE" in all answer boxes). As in the text, (a, a), (B, b), and (y, c) are angle-side opposite pairs. Round to one decimal places, if necessary a = 11, b = 11 c = 11
Answers
Answer: A = 60°, B = 60°, y = 60°, a = 11, b = 11, c = 11.
Using the law of cosines, we can solve for the remaining angles and sides of the triangle. Let's start by finding angle B:
cos(B) = (a^2 + c^2 - b^2) / 2ac
cos(B) = (11^2 + 11^2 - 11^2) / (2 * 11 * 11)
cos(B) = 0.5
B = cos^-1(0.5)
B ≈ 60°
Next, we can find angle y:
cos(y) = (a^2 + b^2 - c^2) / 2ab
cos(y) = (11^2 + 11^2 - 11^2) / (2 * 11 * 11)
cos(y) = 0.5
y = cos^-1(0.5)
y ≈ 60°
Now, we can use the law of sines to find side a:
a / sin(A) = b / sin(B) = c / sin(y)
a / sin(A) = 11 / sin(60°)
sin(A) = a / (11 / sin(60°))
A = sin^-1(sin(A))
A ≈ 60°
Since we now know that all angles of the triangle are 60°, we can conclude that it is an equilateral triangle. Therefore, all sides and angles are equal, and our answers are:
Angle A = 60°
Angle B = 60°
Angle y = 60°
Side a = 11
Side b = 11
Side c = 11

Answers
The correct answer is "lim n rightarrow infinity xn/n! = 0 for all values of x."
To determine whether the series an is absolutely convergent, conditionally convergent, or divergent, we need to apply the appropriate tests. One possible test to use is the ratio test, which compares the absolute value of consecutive terms. Applying the ratio test to the series an, we get:
|an+1/an| = |(3cos(n+1))/(n+1)| ≤ 3/|n+1|
Since the limit of 3/|n+1| as n approaches infinity is zero, the series an is absolutely convergent by the ratio test.
Moving on to the second part of the question, we want to determine for what values of x the series xn/n! is convergent. This series is also known as the power series for e^x. The series converges for all x, which means the correct answer is "x ge 0 for all x."
Finally, we are asked to draw a conclusion about the limit of xn/n! as n approaches infinity. Using the ratio test, we can show that this limit is zero for all values of x.

For the first series, we have:
an = 2, 6cos(1), 18cos(2), 54cos(3), ...
We can use the ratio test to determine whether this series is absolutely convergent, conditionally convergent, or divergent:
|an+1/an| = 3|cos(n+1)/cos(n)|
Since the cosine function oscillates between -1 and 1, the ratio |an+1/an| is not bounded as n goes to infinity. Therefore, the series is divergent.
For the second question, we want to find the values of x such that the series
xn/n! = x/1! + x^2/2! + x^3/3! + ...
is convergent. This is the power series expansion of the exponential function e^x, so the series converges for all real values of x. Therefore, the answer is "x ge 0 for all x".
For the third question, we can use the ratio test to find that the limit of xn/n! as n goes to infinity is zero for all values of x. Therefore, the answer is "lim n rightarrow infinity xn/n! = 0 for all values of x".

prove propositions 4.4 on the existence of angle bisectors. prove that the angle bisector is unique.
Answers
The angle bisector from a vertex to the opposite side of a triangle is unique. We get AD = BE by subtracting BD from both sides of AB + BD = BE.
Proposition 4.4 states that in every triangle, there exists an angle bisector from a vertex to the opposite side and the angle bisector is unique.
Proof:
Let ΔABC be the given triangle and suppose AD is the angle bisector from A to BC. To prove that AD is unique, suppose BE is another angle bisector from B to AC.
We need to show that AD = BE.
Construct the incenter I of ΔABC. Draw lines AI and BI. AI bisects ∠A and BI bisects ∠B.
So, ∠AIB = 90° + ½ ∠C (proved in proposition 4.3).
Again, ∠AIB = ∠AID + ∠BIE [angle addition property of equality]
Therefore, ∠AID + ∠BIE = 90° + ½ ∠C...(1)
Since AD is the angle bisector from A to BC, we have
∠BAD = ∠CAD
Also, BE is the angle bisector from B to AC, so
∠EB = ∠EC
Adding these two equations, we get
∠BAD + ∠EB = ∠CAD + ∠EC...(2)
Since ∠A + ∠B + ∠C = 180° (angle sum property of a triangle),
∠C/2 + ∠B/2 + ∠A/2 = 180° (angle bisector property)
Therefore, ∠A/2 + ∠B/2 = 90° - ∠C/2
So, 2∠A/2 + 2∠B/2 = 180° - ∠C...(3)
Adding equations (1), (2), and (3), we get
∠AID + ∠BIE + ∠BAD + ∠EB + 2∠A/2 + 2∠B/2 = 360° - ∠C/2 + 180° + ∠C/2 + 180° - ∠C
∠AID + ∠BIE + ∠BAD + ∠EB + ∠A + ∠B = 360°(simplifying)
Therefore,
∠AID + ∠BIE + ∠BAD + ∠EB = 180°...(4)
Now, consider ΔABD and ΔEBD.
∠ABD = ∠EBD (∵ AD and BE are angle bisectors)
∠BAD = ∠BED [from equation (2)]
Therefore, ΔABD ≅ ΔEBD (∵ SAS congruence criterion)
So, BD = BD [by CPCTC]
Thus, we get AD = BE [by subtracting BD from both sides of AB + BD = BE]
Hence, the angle bisector from a vertex to the opposite side of a triangle is unique.
