6 0

Answer:

C. | -100 | > 50

Step-by-step explanation:

The left side 100 is greater than 50. Using || pretty much makes the number the inverse/opposite in any equation.

Hopefully this helps :)

If n is an odd number greater than or equal to 3, can n + 1 ever be prime? What if n equals 1?
brilliants [131]
No, because when adding 1 to any odd number it will become even, and all even numbers besides 2 are not prime. This means that if n was 1 the resulting number would be prime, since 2 is prime.

Jon weighs 148 lb and hopes to gain 2 lbs a week.Matt weighs 193lb and hopes to lose 1 lb a week.How many weeks until the weight
cestrela7 [59]
Set up the equation:

Let x be the number of weeks before they weigh the same.

148+2x=193-x

solve:

148+2x=193-x
3x=45
x=15

therefore: it will take 15 weeks until they weigh the same.

Determine the minimum value of f(x, y, z) = 2x 2 + y 2 + 2z 2 + 5 subject to the constraint 3x + 2y + 3z = 4. +
vlada-n [284]
<span>We want to optimize f(x,y,z)=x^2 y^2 z^2, subject to g(x,y,z) = x^2 + y^2 + z^2 = 289. 

Then, ∇f = λ∇g ==> <2xy^2 z^2, 2x^2 yz^2, 2x^2 y^2 z> = λ<2x, 2y, 2z>. 

Equating like entries: 
xy^2 z^2 = λx 
x^2 yz^2 = λy 
x^2 y^2 z = λz. 

Hence, x^2 y^2 z^2 = λx^2 = λy^2 = λz^2. 

(i) If λ = 0, then at least one of x, y, z is 0, and thus f(x,y,z) = 0 <---Minimum 
(Note that there are infinitely many such points.) 
(f being a perfect square implies that this has to be the minimum.) 

(ii) Otherwise, we have x^2 = y^2 = z^2. 
Substituting this into g yields 3x^2 = 289 ==> x = ±17/√3. 

This yields eight critical points (all signage possibilities) 
(x, y, z) = (±17/√3, ±17/√3, ±17/√3), and  
f(±17/√3, ±17/√3, ±17/√3) = (289/3)^3 <----Maximum 

I hope this helps! </span><span>

A club with five members will randomly select the president and vice president. Each possible pair will be assigned an equal por
Tju [1.3M]

Answer:

C. 20

Step-by-step explanation:

The order in which the members are selected is important. The first one selected is the president and the second is the vice president.

So we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

In this problem:

2 people are going to be chosen from a set of 5. So

P_{(5,2)} = \frac{5!}{(5-2)!} = 20

So the correct answer is:

C. 20
