The velocity of a train starting from rest moves with a uniform acceleration of 5 m/s2 would be 100 m/s.
Acceleration = 5 m/s2
Distance, s = 1 km = 1000m
Intital velocity, u=0 m/s
What is the first equation of motion?We know that, Newton's equation of motion,
s = ut+ 1/2 at^2
1000 = 0 + 1/2 x 5 x t^2
1000 = 5/2 x t^2
2000/ 5 = t^2
t = 20 s
Also,a = (v-u)/t
5 = v-0/20
100 = v
v = 100 m/s
Hence, the velocity of a train starting from rest moves with a uniform acceleration of 5 m/s2 would be 100 m/s.

how to determine if a binomial is a factor of a polynomial
A binomial is a factor of a polynomial has been determined by using the
polynomial division method.
To determine if a binomial is a factor of a polynomial, you can use the polynomial division method. The basic idea is to divide the polynomial by the binomial and check if the remainder is zero. If the remainder is zero, then the binomial is a factor of the polynomial. Here's the step-by-step process:
Write the polynomial and the binomial in standard form, with the terms arranged in descending order of their exponents.
Perform the long division of the polynomial by the binomial, similar to how you would divide numbers. Start by dividing the highest degree term of the polynomial by the highest degree term of the binomial.
Multiply the binomial by the quotient obtained from the division and subtract the result from the polynomial.
Repeat the division process with the new polynomial obtained from the subtraction step.
Continue dividing until you reach a point where the degree of the polynomial is lower than the degree of the binomial.
If the remainder is zero, then the binomial is a factor of the polynomial. If the remainder is non-zero, then the binomial is not a factor.

What is the length of AC in the given triangle?
Answer: the answer is 126.6
Step-by-step explanation:
Answer:
AC ≈ 126.6
Step-by-step explanation:
The law of sines can be used to find the side length of interest in this triangle. It tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
__
missing angleIn order to use the law of sines, we must have a side length and its opposite angle. Here, the angle opposite the given side is unmarked, so we need to compute it using the angle sum theorem.
A +B +C = 180°
A +85° +53° = 180°
A = 42° . . . . . . . . . . . . . subtract (85°+53°)
unknown sideThen side AC can be found from ...
AC/sin(B) = BC/sin(A)
AC = BC·sin(B)/sin(A) = 85·sin(85°)/sin(42°)
AC ≈ 126.547

Find the largest possible value for the rank of A and the smallest possible value for the nullity of A. A is 6x6.
The rank of a matrix is the number of linearly independent rows or columns. Since A is a 6x6 matrix, the maximum possible rank is 6, which means that all 6 rows or columns are linearly independent.
The nullity of a matrix is the dimension of the null space, which is the set of all solutions to the equation Ax=0. By the rank-nullity theorem, the nullity of A is equal to the dimension of the column space (range) minus the rank of A. Since the rank of A can be at most 6, the smallest possible value for the nullity of A is 0, which occurs when the column space (range) is the entire 6-dimensional space.
Therefore, the largest possible value for the rank of A is 6, and the smallest possible value for the nullity of A is 0.
Given that A is a 6x6 matrix, the largest possible value for the rank of A is 6, which occurs when all rows (or columns) are linearly independent. The smallest possible value for the nullity of A is 0, which happens when there are no non-trivial solutions in the null space of A. In this case, the rank-nullity theorem states that rank(A) + nullity(A) = 6, which holds true when rank(A) = 6 and nullity(A) = 0.

Which measure of center should Raul use to calculate his overall performance if he hits a line drive to the outfield on each pitch?
Since the distribution of the 10 distances is not uniform, Raul should use the median to determine his total performance.
What is median?The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory.
It could be referred to as "the middle" value for a data set.
The fundamental difference between the mean and the median when describing data is that the median is more representative of the "normal" value because it is not skewed by a tiny fraction of exceptionally big or small values.
Due to the fact that income distribution can be very skewed, the median income, for instance, might be a better indicator of what is considered a "normal" income.
Given that it is the most resilient statistic, the median is crucial to strong statistics.
According to our question-
The home run is an outlier in the data set even if nine lengths are grouped together.
The median is the most accurate indicator of the middle of a data collection including outliers.

Sketch an angle theta in standard position such that theta has the least possible positive measure and the point (-2, Square root three) is on the terminal side of theta. Then find the exact values of the six trigonometric functions for each angle
A sketch of the angle is attached and the six trigonometric functions for each angle are;
sinθ = -½
cosθ = -(√3)/2
tanθ = (√3)/3
cscθ = -2
secθ = -(2√3)/3
cotθ = √3
How to find the trigonometric ratios?
We can use the unit circle to figure out the trigonometric functions of θ.
Both the x- and y- coordinates are in the third quadrant, so θ is an obtuse angle (210°), as seen in the figure below.
An angle in standard position is an angle measured with respect to the +x semi-axis. In this question we must derive the six trigonometric functions from the distances between a given point and the origin. The trigonometric functions are described below:
sinθ = -2/4 = -½
cosθ = (-2√3)/4 = -(√3)/2
tanθ = -2/(-2√3) = 1/√3 = (√3)/3
cscθ = 1/sin θ = 1/-½ = -2

consider an invertible symmetric n×n matrix a. when does there exist a nonzero vector v in rn such that av is orthogonal to v? give your answer in terms of the signs of the eigenvalues of a.
If an invertible symmetric n×n matrix A has a nonzero vector v in R^n such that Av is orthogonal to v, then it means that the dot product of Av and v is equal to zero. In other words, Av . v = 0. Using th peroperties of the dot product, we can rewrite this equation as:
v . A^T v = 0
Since A is symmetric, A^T = A, and we can rewrite the equation as:
v . A v = 0
This equation can be further simplified using the properties of the dot product:
v . A v = (A v) . v = 0
From this equation, we can see that the eigenvalues of A must be either positive or negative. If the eigenvalues of A are all positive, then v . A v > 0, which contradicts the equation v . A v = 0. Similarly, if the eigenvalues of A are all negative, then v . A v < 0, which also contradicts the equation v . A v = 0.
Therefore, the only way for there to exist a nonzero vector v in R^n such that Av is orthogonal to v is if the eigenvalues of A are both positive and negative. In other words, A must have both positive and negative
eigenvalues.

Simplify your answer as much as possible.
If there is more than one solution, Separate them with commas.
If there is no solution, Click on "No solution".
Answer:
The values of x is -7 and 7.
Step-by-step explanation:
First, you have to make the equation equals to 0 :
x² = 49
x² - 49 = 0
Given that x² and 49 are perfect square of x and 7 so you have to apply (a + b)(a - b) = a² - b² :
x² - 49 = 0
(x + 7)(x - 7) = 0
Lastly, you have to solve it :
(x + 7)(x - 7) = 0
x + 7 = 0
x = -7
x - 7 = 0
x = 7
Use the Buying a Car information above to answer this question. What is your monthly payment if you choose 0% financing for 48 months? Round to the nearest dollar. Use the Buying a Car information above to answer this question. The rebate offer is $2900, and you can obtain a car loan at your local bank for the balance at 5.24% compounded monthly for 48 months. If you choose the rebate, what is your monthly payment? $ Round to the nearest dollar.
If you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).
To calculate the monthly payment for each financing option, we'll use the information provided:
1. 0% financing for 48 months:
Since the financing is offered at 0% interest, the monthly payment can be calculated by dividing the total purchase price by the number of months.
Purchase Price: $26,050
Number of Months: 48
Monthly Payment = Purchase Price / Number of Months
Monthly Payment = $26,050 / 48 ≈ $543
Therefore, the monthly payment for the 0% financing option for 48 months is approximately $543.
2. Rebate offer and car loan at the bank:
If you choose the rebate offer, you'll need to finance the remaining balance after deducting the rebate amount. Let's calculate the remaining balance:
Purchase Price: $26,050
Rebate Offer: $2,900
Remaining Balance = Purchase Price - Rebate Offer
Remaining Balance = $26,050 - $2,900 = $23,150
Now, we'll calculate the monthly payment using the remaining balance and the loan terms from the local bank:
Remaining Balance: $23,150
Interest Rate: 5.24% (compounded monthly)
Number of Months: 48
Monthly Payment = (Remaining Balance * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))
First, let's calculate the Monthly Interest Rate:
Monthly Interest Rate = Annual Interest Rate / 12
Monthly Interest Rate = 5.24% / 12 ≈ 0.437%
Now, we can calculate the Monthly Payment using the formula mentioned above:
Monthly Payment = ($23,150 * 0.437%) / (1 - (1 + 0.437%)^(-48))
Monthly Payment ≈ $557
Therefore, if you choose the rebate offer, your monthly payment for the car loan at the bank will be approximately $557 (rounded to the nearest dollar).

Taylor bought a watch onsale for 60% off the originalprice, and another 10% off thediscounted price. If the watchoriginally cost $82, what wasthe final sale price?
Original Cost - $82
First part: Apply the 60% off discount
Convert first the 60% into decimal form
60% ÷ 100% = 0.6
Multiply it to the original cost to determine the discount
$82 ˣ 0.6 = $49.2
Subtract the discount to the original price, to determine the discounted price.
$82 - $49.2 = $32.8
Second part:
The discounted price is now $32.8 for which we will apply another 10% discount.
Again, convert 10% into decimal
10% ÷ 100% = 0.1
Multiply it to the discounted price, to determine the second discount.
$32.8 ˣ 0.1 = $3.28
Subtract the discount to the already discounted price.
$32.8 - $3.28 = $29.52
Therefore, the final sale price of the watch is at $29.52.

The set of free variables found in the expression (λx.λy.y (λz.x)) (λx.z) is { } (the empty set).
To find the set of free variables in the given lambda calculus expression, we need to identify all variables that are not bound by any lambda abstraction.
Starting from the innermost expression (λx.z), we see that x is bound by the lambda abstraction, so x is not a free variable. Moving outward to the next expression (λy.y (λz.x)), we see that y is also bound by the lambda abstraction, so y is not a free variable. Finally, we reach the outermost expression (λx.λy.y (λz.x)), where the only occurrence of x is bound by the lambda abstraction.
Since there are no variables in the expression that are not bound by any lambda abstraction, the set of free variables is { } (the empty set).

The point (9, -7) is the only solution to the system of linear inequalities given.
To determine which point would be a solution to the system of linear inequalities, let's substitute the given points into the inequalities and see which point satisfies both inequalities.
The system of linear inequalities is:
y > -4x + 6
y > (1/3)x - 7
Let's test each given point:
For the point (9, -7):
Substituting the values into the inequalities:
-7 > -4(9) + 6
-7 > -36 + 6
-7 > -30 (True)
-7 > (1/3)(9) - 7
-7 > 3 - 7
-7 > -4 (True)
Since both inequalities are true for the point (9, -7), it is a solution to the system of linear inequalities.
For the point (-12, -2):
Substituting the values into the inequalities:
-2 > -4(-12) + 6
-2 > 48 + 6
-2 > 54 (False)
-2 > (1/3)(-12) - 7
-2 > -4 - 7
-2 > -11 (False)
Since both inequalities are false for the point (-12, -2), it is not a solution to the system of linear inequalities.
For the point (12, 1):
Substituting the values into the inequalities:
1 > -4(12) + 6
1 > -48 + 6
1 > -42 (True)
1 > (1/3)(12) - 7
1 > 4 - 7
1 > -3 (True)
Since both inequalities are true for the point (12, 1), it is a solution to the system of linear inequalities.
For the point (-12, -7):
Substituting the values into the inequalities:
-7 > -4(-12) + 6
-7 > 48 + 6
-7 > 54 (False)
-7 > (1/3)(-12) - 7
-7 > -4 - 7
-7 > -11 (True)
Since one inequality is true and the other is false for the point (-12, -7), it is not a solution to the system of linear inequalities.
In conclusion, the point (9, -7) is the only solution to the system of linear inequalities given.
