Which of the following arguments are invalid and which are valid? Prove your answer by replacing each proposition with a variable to obtain the form of the argument. Then prove that the form is valid or invalid. The patient has high blood pressure or diabetes or both. The patient has diabetes or high cholesterol or both. The patient has high blood pressure or high cholesterol.
Both arguments are valid.
The validity of the arguments can be determined by using the concept of propositional logic.
The patient has high blood pressure or diabetes or both. The patient has diabetes or high cholesterol or both.This argument can be represented as: (P∨D∨B)∧(D∨C∨B). The form of the argument is p ∧ q, which is a valid form.
The patient has high blood pressure or high cholesterol.This argument can be represented as: P∨C. The form of the argument is p ∨ q, which is also a valid form.
So, both arguments are valid. The validity of an argument depends on the form of the argument and not the specific proposition used. In both cases, the form of the argument is valid, so the argument is also valid.

the length ll of a tangent, drawn from a point aa to a circle, is \frac{4}{3} 3 4 of the radius r. the (shortest) distance from aa to the circle is:
The shortest distance from point A to the circle is zero. In other words, point A lies on the circle itself.
Length of the tangent, LL = (4/3) * r, where r is the radius of the circle.
We need to find the shortest distance from point A to the circle.
The shortest distance from an external point to a circle is along the line connecting the point and the center of the circle, perpendicular to the tangent.
Let's assume that the center of the circle is point O.
Now, consider the right triangle formed by the line segment AO, the radius of the circle (r), and the shortest distance (h) from point A to the circle.
By Pythagoras' theorem, we have:
AO^2 = h^2 + r^2
Since AO is the radius of the circle, it is equal to r:
r^2 = h^2 + r^2
Subtracting r^2 from both sides, we get:
0 = h^2
This implies that h = 0.
As a result, zero is the shortest distance between point A and the circle. Point A is therefore located on the circle itself.

Answer:
10:12, 5:24, 9:13+1/3, 3:40, 20:6, 7:17+1/7
Step-by-step explanation:
You simply divide 120 by each of the numbers.
120/10=12, 120/5=24, 120/9=40/3, 120/3=40, 120/20=6, 120/7=12+1/7
Thrice a number when increased by 6 gives 24
Answer:6
Step-by-step explanation:
Let the number be x.
Now, 3x+6=24
3x=24-6
3x=18
x=18/3
x=6
Answer:
6
Step-by-step explanation:
We can work the problem backwards
Since something gives 24 that means it equals 24
= 24
Something increased by 6, so something added by 6
Something + 6 = 24
Making something = x
x + 6 = 24
If we subtract 6 from both sides
x = 18
Trice a number, so divide this number by 3
x = 6
Trice of 6 is 18... 18 increased by 6 gives 24
As an employee of the architectural firm of Brown and Farmer, you have been asked to design a silo to stand adjacent to an existing barn on the campus of the local community college. You are charged with finding the dimensions of the least expensive silo that meets the following specifications.
The silo will be made in the form of a right circular cylinder surmounted by a hemi-spherical dome.
It will stand on a circular concrete base that has a radius 1 foot larger than that of the cylinder.
The dome is to be made of galvanized sheet metal, the cylinder of pest-resistant lumber.
The cylindrical portion of the silo must hold 1000π cubic feet of grain.
Estimates for material and construction costs are as indicated in the diagram below.
The design of a silo with the estimates for the material and the construction costs.
The ultimate proportions of the silo will be determined by your computations. In order to provide the needed capacity, a relatively short silo would need to be fairly wide. A taller silo, on the other hand, could be rather narrow and still hold the necessary amount of grain. Thus there is an inverse relationship between r, the radius, and h, the height of the cylinder.
The construction cost for the concrete base is estimated at $20 per square foot. Again, if r is the radius of the cylinder, what would be the area of the circular base? Note that the base must have a radius that is 1 foot larger than that of the cylinder. Write an expression for the estimated cost of the base.
Surface area of base = ____________________
Cost of base = ____________________
It should be noted that C = π(R + 1)² × 20 is an expression for the estimated cost of the base.
How to calculate the expressionThe surface area of the base is given by
A = πr²
where r is the radius of the base. Since the radius of the base is 1 foot larger than the radius of the cylinder, we have
r = R + 1
Substituting this into the expression for the area of the base gives
A = π(R + 1)²
The cost of the base is given by
C = A * 20
C = π(R + 1)² * 20
This is an expression for the estimated cost of the base.

Find the set of values of x for which x^2-x-6>0 and 10-2x<5
Answer:
No Solution.
Step-by-step explanation:
For starters, here are our two equations:
\((x^2-x-6)>0\)
\(10-2x<5\)
The first option is to solve for x in our second equation. First, we add 2x to both sides to get \(10<5+2x\). Then, we subtract 5 from both sides to get \(2x<5\). Finally, we divide both sides by 2 to get \(x<2.5\). We can plug in 2.5 into our second equation to test if it works. If it does not work, then anything less than 2.5 won't work, and the solution would be impossible.
Now we can plug in our values into our first equation. We now have the equation \(2.5^2-2.5-6>0\). We can simplify to get \(-2.25>0\). This test failed, so there are no solutions. A solution would be impossible.

Tenth term:
\(\sf A_{10}= -4(2)^{10-1}\) ⇒ \(\sf A_{10}= -2048\)
Answer:
\(\sf a_1=-4\\a_2=-12\\a_3=-20\\a_4=-28\\a_5=-36\\a_{10}=-76\)
Step-by-step explanation:
\(\textsf{Given sequence}: \sf a_n=-4(2n-1)\)
This formula is for the nth term of the sequence.
Therefore, to find any term of the sequence, substitute the position of the term you wish to find as n.
For example, to find the 10th term, substitute n = 10 into the formula:
\(\begin{aligned}\sf a_{10} & =-4[2(10)-1)]\\ & = -4(20-1)\\ & = -4(19)\\ & = -76\end{aligned}\)
To find the first 5 terms, substitute n = 1 through n = 5 into the formula:
\(\sf a_1=-4[2(1)-1]=-4(2-1)=-4(1)=-4\)
\(\sf a_2=-4[2(2)-1]=-4(4-1)=-4(3)=-12\)
\(\sf a_3=-4[2(3)-1]=-4(6-1)=-4(5)=-20\)
\(\sf a_4=-4[2(4)-1]=-4(8-1)=-4(7)=-28\)
\(\sf a_5=-4[2(5)-1]=-4(10-1)=-4(9)=-36\)

Answer:
G
Step-by-step explanation:
a + b + c = 80
Express a and c in terms of b using the ratios in fractional form, that is
\(\frac{a}{b}\) = \(\frac{2}{3}\) ( cross- multiply )
3a = 2b ( divide both sides by 3 )
a = \(\frac{2}{3}\) b
\(\frac{b}{c}\) = \(\frac{3}{11}\) ( cross- multiply )
3c = 11b ( divide both sides by 3 )
c = \(\frac{11}{3}\) b
Substitute the values for a and c into the original equation
\(\frac{2}{3}\) b + b + \(\frac{11}{3}\) b = 80 ( multiply through by 3 to clear the fractions )
2b + 3b + 11b = 240 , that is
16b = 240 ( divide both sides by 16 )

Consider the space L²[0, 1]. Let p(f) = - (11/1²) + L ₂1/1₁ + SIS), ƒ € 1²[0, 1]. 0 Is p(f) a norm, and if it is, is it equivalent to the standard L²-norm || f ||2= =(√₁₁/1²) 1¹/² ?
P cannot be bounded below by any multiple of ||·||₂, since ||f||₂ can be
Let's first examine whether p(f) satisfies the definition of a norm.
To be a norm, p(f) must satisfy the following properties for all f ∈ L²[0, 1]:
Non-negativity: p(f) ≥ 0
Definiteness: p(f) = 0 if and only if f = 0 almost everywhere
Homogeneity: p(αf) = |α|p(f) for any scalar α
Triangle inequality: p(f+g) ≤ p(f) + p(g) for any f, g ∈ L²[0, 1]
Non-negativity:
We have - (11/1²) ≤ 0 for all f, and clearly ||f||₂ ≥ 0 as well. Therefore, p(f) is non-negative.
Definiteness:
If p(f) = 0, then we must have f = 0 almost everywhere, since the constant function 1 belongs to L²[0, 1] and has a nonzero integral. Conversely, if f = 0 almost everywhere, then p(f) = 0. Therefore, p(f) satisfies the definiteness property.
Homogeneity:
For any scalar α, we have:
p(αf) = - (11/1²) + ||αf||₂¹ + ∫₀¹ |αf'|² dx
= - (11/1²) + |α|²||f||₂¹ + ∫₀¹ |αf'|² dx
= |α|(- (11/1²) + ||f||₂¹ + ∫₀¹ |f'|² dx)
= |α|p(f),
so p(f) satisfies the homogeneity property.
Triangle inequality:
For any f, g ∈ L²[0, 1], we have:
p(f+g) = - (11/1²) + ||f+g||₂¹ + ∫₀¹ |(f+g)'|² dx
= - (11/1²) + ||f||₂¹ + ||g||₂¹ + 2∫₀¹ |f'g'| dx + ∫₀¹ |g'|² dx + ∫₀¹ |f'|² dx
≤ - (11/1²) + ||f||₂¹ + ||g||₂¹ + 2(||f'||₂ ||g||₂ + ||f||₂ ||g'||₂) + ||f'||₂² + ||g'||₂² + ||f||₂² + ||g||₂²
≤ - (11/1²) + 2(||f||₂¹ + ||g||₂¹) + 2(||f'||₂² + ||g'||₂²)
= (2-11/1²)(||f||₂¹ + ||g||₂¹)
= 3(||f||₂¹ + ||g||₂¹)
= 3(p(f) + p(g)),
where we have used the Cauchy-Schwarz inequality and the fact that ||f+g||₂ ≤ ||f||₂ + ||g||₂. Therefore, p(f) satisfies the triangle inequality.
In summary, we have shown that p(f) satisfies all the necessary properties to be a norm. Now, let's examine whether it is equivalent to the standard L²-norm ||f||₂.
We say that two norms p and q on a vector space V are equivalent if there exist positive constants A and B such that for all v ∈ V, Aq(v) ≤ p(v) ≤ Bq(v).
Let's first consider the upper bound. For any f ∈ L²[0, 1], we have:
p(f) = - (11/1²) + ||f||₂¹ + ∫₀¹ |f'|² dx
≤ 1||f||₂ + ||f'||₂² + 1
≤ (√2 + 1) ||f||₂,
where we have used the Cauchy-Schwarz inequality and the fact that ||f'||₂² ≤ 2||f||₂². Therefore, p is dominated by ||·||₂ with a constant of √2 + 1.
Now let's consider the lower bound. For any ε > 0, we can choose a function f ∈ L²[0, 1] such that:
(11/1²) + ||f||₂¹ + ∫₀¹ |f'|² dx < ||f||₂ + ε
This is possible because ||f'||₂ → 0 as ||f||₂ → 0. Therefore, p cannot be bounded below by any multiple of ||·||₂, since ||f||₂ can be

The correct answer is the janitor is mopping at a rate of 1/15 of a classroom per minute and this is a proper fraction.
It is given in the question that a school janitor has moped \(\frac{1}{3}\) of classroom in 5 minutes.
We have to find the rate at which he is moping
We will divide \(\frac{1}{3}\) by 5, to divide by 5 we will multiply \(\frac{1}{3}\) with reciprocal of 5 that is \(\frac{1}{5}\)
\(\frac{1}{3}\)× \(\frac{1}{5}\) = \(\frac{1}{15}\)
Hence, the janitor is mopping at a rate of 1/15 of a classroom per minute.
This fraction is proper fraction If the numerator of a fraction is less than the denominator, the fraction is said to be a correct fraction.
