Let's first write the vector equation of the two lines r1 and r2. r1(t)=⟨3t+5,−3t−5,2t−2⟩r2(t)=⟨11−6t,6t−11,2−4t⟩
The direction vector for r1 will be (3,-3,2) and the direction vector for r2 will be (-6,6,-4).If the dot product of two direction vectors is zero, then the lines are orthogonal or perpendicular. But here, the dot product of the direction vectors is -18 which is not equal to 0.
Therefore, the lines are not perpendicular or orthogonal. If the lines are not perpendicular, then we can tell if the lines are distinct parallel lines or skew lines by comparing their direction vectors. Here, we see that the direction vectors are not multiples of each other.So, the lines are skew lines. Choice: The lines are skew.

a cylindrical tank for refrigerant has an inside diameter of 14 inches and is 16 inches high. what is the volume of the tank in cubic inches?
The volume of the cylindrical tank for refrigerant with an inside diameter of 14 inches and a height of 16 inches is 10,736 cubic inches.
The volume of a cylinder can be calculated using the formula:
\(\[ V = \pi r^2 h \]\)
where V represents the volume, \(\(\pi\)\) is a mathematical constant approximately equal to 3.14159, r is the radius of the cylinder (which is half the diameter), and h is the height of the cylinder.
In this case, the inside diameter of the tank is given as 14 inches, so the radius can be calculated as \(\(r = \frac{14}{2} = 7\)\) inches. The height of the tank is given as 16 inches. Substituting these values into the formula, we get:
\(\[ V = 3.14159 \times 7^2 \times 16 \approx 10,736 \text{ cubic inches} \]\)
Therefore, the volume of the cylindrical tank for refrigerant is approximately 10,736 cubic inches.

The number of zeros of a polynomial is related to the highest power of the polynomial. According to the Fundamental Theorem of Algebra, a polynomial of degree n can have at most n distinct zeros. The degree of a polynomial corresponds to the highest power of the polynomial.
For example, a polynomial of degree 3 (highest power is 3) can have at most 3 distinct zeros. However, it's important to note that some zeros may be repeated or complex, so the number of distinct zeros might be less than the degree of the polynomial.
This relationship between the number of zeros and the highest power of a polynomial provides insight into the behavior and roots of polynomial functions.

Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £78.40. They share the tips in the ratio 1:3:5. How much more does Colin get over Paul?
Answer:
Share of Paul = 2/8*78.40=19.6
Share of Colin = 5/8*78.40=49
And
Share of Brian =1/8*78.40=9.8
Step-by-step explanation:
They share the tips in the ratio 2:5:1.
It means , the total share is 8 ,
that 2 out of 8 is the share of Paul
5 out of 8 is the share of Colin
And 1 out of 8 is the share of Brain
Now total tip = 78.40
Share of Paul = 2/8*78.40=19.6
Share of Colin = 5/8*78.40=49
And
Share of Brian =1/8*78.40=9.8

a continuous random variable x has a uniform distribution between 5 and 15 (inclusive), then the probability that x falls between 10 and 20 is 1.0. a. true b. false
b. The statement "the probability that x falls between 10 and 20" is false.
A continuous random variable X has a uniform distribution between 5 and 15 (inclusive), meaning it can take any value between 5 and 15 with equal probability.
We need to find the probability that X falls between 10 and 20. Since the range of X is only between 5 and 15, we can only consider the range of 10 to 15 within this interval.
For a uniform distribution, the probability density function (pdf) is:
f(x) = 1 / (b - a)
where 'a' and 'b' are the lower and upper limits of the distribution, respectively. In this case, a = 5 and b = 15, so:
f(x) = 1 / (15 - 5) = 1 / 10
Now, to find the probability that X falls between 10 and 15, we can integrate the pdf over this interval:
P(10 ≤ X ≤ 15) = ∫[1/10]dx from 10 to 15
P(10 ≤ X ≤ 15) = [x/10] from 10 to 15
P(10 ≤ X ≤ 15) = (15/10) - (10/10) = 1/2
So, the probability that X falls between 10 and 20 is 1/2, not 1.0. Therefore, the statement is the probability that x falls between 10 and 20 is false.

How to obtain the volume of a rectangular prism?The volume of a rectangular prism, with dimensions length, width and height, is given by the multiplication of these dimensions, according to the equation presented as follows:
Volume = length x width x height.
The dimensions for this problem are given as follows:
h = w + 4, w and 49 - w.
Hence the equation for the volume is given as follows:
w(w + 4)(49 - w) = 8820
w³ - 45w² - 196w + 8820 = 0.
Inserting the equation into a cubic equation calculator, the smallest value of w is:
w = 14.
Hence the smallest height is of:
w + 4 = 18 inches.

Step-by-step explanation:
if r is the ring of integers, let u be the ideal consisting of all multiples of 17. prove that if v is an ideal of r and r ⊃ v ⊃ u then either v = r or v = u. generalize!
(a) is a prime ideal of R, and since v is contained in (a), we have either v = (a) or v = R. Therefore, The only ideals of R containing u are u and R itself.
To prove that if v is an ideal of r and r ⊃ v ⊃ u, then either v = r or v = u, we need to use the fact that the only ideals of r are the trivial ones (0 and r) and the maximal ones (prime ideals). Since u is not a prime ideal (since it contains multiples of 17), the only possibilities for v are u and r. To see this, suppose that v is a proper ideal of r containing u. Then there exists some non-zero element a in v that is not in u. Since a is not a multiple of 17, it must have a prime factor p that is not 17 (otherwise, it would be a multiple of 17). But then (a) is a prime ideal of r (since r is a UFD), and since v is contained in (a), we have either v = (a) or v = r. Therefore, we have shown that if v is an ideal of r and r ⊃ v ⊃ u, then either v = r or v = u. We can generalize this result to any ring R and any proper ideal u of R by using the same argument. If v is a proper ideal of R containing u, then there exists some non-zero element a in v that is not in u. But then (a) is a prime ideal of R, and since v is contained in (a), we have either v = (a) or v = R. Therefore, the only ideals of R containing u are u and R itself.
