Find an equation of the plane through the points P1(−2, 1, 4), P2(1, 0, 3) that is perpendicular to the plane
4x − y + 3z = 2.
Answers
This is the equation of the plane containing P1 and P2 that is perpendicular to the plane 4x − y + 3z = 2.
To find an equation of the plane through the points P1(-2, 1, 4) and P2(1, 0, 3) that is perpendicular to the plane 4x − y + 3z = 2, we can use the following steps:
Find a normal vector to the plane containing P1 and P2 by taking the cross product of the vectors (-2, 1, 4) and (1, 0, 3). The cross product is (-12, -5, 2). This vector is perpendicular to the plane containing P1 and P2.
Use the point-normal form of the equation of a plane to find the equation of the plane containing P1 and P2. Let (x, y, z) be any point on the plane. Then the equation of the plane is given by the dot product of the normal vector with the vector from any point on the plane to the given point (P1 in this case):
(-12, -5, 2) · ((x, y, z) - (-2, 1, 4)) = 0
Expanding the dot product and simplifying, we get:
-12x - 5y + 2z + 35 = 0
This is the equation of the plane containing P1 and P2 that is perpendicular to the plane 4x − y + 3z = 2.

twenty five people, consisting of women and men are lined up in a random order. find the probability that the ninth woman to appear is in position 17. that is, find the probability there are women in positions thru and a woman in position 17
Answers
The probability that the ninth woman to appear is in position 17 is about 5.59%
We can approach this problem by using the binomial probability distribution. Let X be the number of women among the first 16 people in the line. Then X follows a binomial distribution with parameters n = 16 and p, the probability that any given person among the first 16 is a woman. We want to find the probability that X = 8, since this means that the ninth woman to appear is in position 17.
The probability of any given person being a woman is not specified in the problem, but we can assume that it is 0.5 for simplicity. Therefore, p = 0.5, and we can use the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where (n choose k) is the binomial coefficient, which gives the number of ways to choose k items from a set of n items. In this case, it gives the number of ways to choose k women from the first 16 people in the line.
Using this formula with n = 16 and k = 8, we get:
P(X = 8) = (16 choose 8) * 0.5^8 * 0.5^8
= 12870 * 0.00390625
= 50.27
This means that the probability of exactly 8 women appearing among the first 16 people in the line is about 50.27%.
Given that there are 8 women among the first 16 people, the probability that the ninth woman appears in position 17 is 1/9, since there are 9 possible positions for the ninth woman to appear, and they are all equally likely.
Therefore, the overall probability that the ninth woman to appear is in position 17 is:
P(X = 8) * (1/9) = 50.27% * (1/9) = 5.59%

In Δ RST, m ∠ R=37°, m ∠ T=59°, and T S=12 in. Find R S .
Answers
In triangle RST, with angle R measuring 37°, angle T measuring 59°, and side TS measuring 12 inches, we need to find the length of side RS.
To find the length of side RS, we can use the Law of Sines, which states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.
Using the Law of Sines, we have the following ratio: RS/sin(37°) = TS/sin(59°).
Substituting the known values, we get RS/sin(37°) = 12/sin(59°).
To find RS, we can rearrange the equation: RS = (12 * sin(37°)) / sin(59°).
Evaluating the sine values, we have RS = (12 * 0.6018) / 0.8572.
Simplifying further, RS ≈ 8.4174 inches.
Therefore, the length of side RS in triangle RST is approximately 8.4174 inches.

If g(x)=f(x)+k g ( x ) = f ( x ) + k , what is the value of k?
Answers
The value of k for the given relation of the function represented by attached graph is equal to 3.
Two function f(x) and g(x) .
Relation between f(x) and g(x) is equal to,
g ( x ) = f ( x ) + k
From the attached graph of the function f(x) and g(x) we have,
Slope of both the function f(x) and g(x) is equal to
Slope of f(x) = ( 2 -1 )/( 0 - (-3))
= 1/3
Slope of g(x) = (5 - 4)/ ( 0 - (-3))
= 1/3
Both the lines are parallel to each other with different value of intercept.
y-intercept of f(x) is equal to 2.
y-intercept of g(x) is equal to 5.
As g(x) = f(x) + k
Substitute the value we have,
⇒ 5 = 2 + k
⇒ k = 3
Therefore, for the given attached graph the value of k is equal to 3.

if u is a subspace of a finite dimensional vector space can it be an infinite dimensional vector space?
Answers
No a subspace of a finite dimensional vector space cannot be an infinite dimensional vector space
This is due to the fact that a subspace is a subset of a larger vector space and must have the same dimension as its parent vector space. In other words we can say that, if the parent vector space is finite dimensions,then the subspace must be as well.
To put it in another way, a vector space is finite dimensional if it can be traversed by a limited number of vectors. A subspace can only be spanned by a subset of the vectors that span the parent vector space since it is a subset of a larger vector space. As a result, if the parent vector space has finite dimensions, the subspace must be as well.

Answers
According to the information, it will take 2.75 seconds for the T-shirt to reach its maximum height. The maximum height of the T-shirt is 107.375 feet above the field.
How to find the time it takes for the T-shirt to reach its maximum height?To find the time it takes for the T-shirt to reach its maximum height, we need to determine the value of t when the velocity (v) is zero. In the given equation h(t) = -16t^2 + 88t + 3, the maximum height is reached when the velocity is zero. We can find the time by taking the derivative of the equation and setting it equal to zero:
v(t) = h'(t) = -32t + 88-32t + 88 = 0t = 2.75 secondsSo, it will take 2.75 seconds for the T-shirt to reach its maximum height.
To find the maximum height, we substitute the value of t back into the equation:
h(2.75) = -16(2.75)^2 + 88(2.75) + 3
h(2.75) = 107.375 feet

Answers
The change in the accounts receivable is -$373,816.23 if the firm's management wanted its to be done in 35 days.
Here we have to find the change in the accounts receivable.
The given data:
Sales = $ 9,745,923
inventory = $ 2,237,435
cash = $ 755,071
day's sales outstanding(DSO) = 49 days
Formula to find DSO:
DSO = 365/ accounts receivable turnover
= 365/ ( net sales/ accounts receivable)
= 365 × accounts receivable/ net sales
Account receivables = DSO × net sales / 365
= 49 × 9,745,923 / 365
= $1,308,356.70
Target DSO = 35 days
Net accounts received = DSO × net sales / 365
= 35 × 9,745,923 / 365
= $934,540.56
ΔAccounts received = $1,308,356.79 - $ 934,540.56
= - $373,816.23
Therefore change in accounts received is -$373,816.23.
