You can rent time on computers at the local copy center for 35 minutes with $25.

To find out how much time you can rent for $25 at the local copy center, follow these steps:

1. Subtract the $10 setup charge from the total amount you have: $25 - $10 = $15.
2. Now you have $15 left for renting time on the computers. Since it costs $2 for every 5 minutes, you need to find out how many 5-minute increments can be covered by $15.
3. Divide the remaining amount by the cost per 5-minute increment: $15 / $2 = 7.5. Since you can't have half an increment, round down to 7.
4. Multiply the number of 5-minute increments by the time per increment: 7 * 5 = 35 minutes.

So, you can rent time on computers at the local copy center for 35 minutes with $25.

Null space is defined as the set of vectors 'x' in Rn that are solutions to the matrix equation A*x = 0. False: The set of all vectors of the form 1 x y where x and y range over all real numbers is a subspace of R3. True: The set of all vectors of the form 0 x y where x and y range over all real numbers is not a subspace of R3.

1) False Null space can consist of zero vector only. A null space is defined as the set of vectors 'x' in R^n that are solutions to the matrix equation A*x = 0.

2) True The number of columns can never be less than the number of rows of the matrix in order for a null space to exist, hence a 4x3 matrix may have the null space of only the zero vector.

3) True The set of all vectors of the form 1 x y where x and y range over all real numbers, is a subspace of R^3. This set contains zero vector because for x=0 and y=0, we get the vector as [0,0,0]. Hence it is a subspace of R^3.

4) False The set of all vectors of the form 0 x y where x and y range over all real numbers, is not a subspace of R^3 as it doesn't contain zero vector. To have a subspace of R^3, it should contain a zero vector.

Answer:

Kiana's conclusion is incorrect. Kiana needs to sell 31 hair products

Step-by-step explanation:

The equation written doesn't factor in the $65.25 that she already had saved. The correct equation would be 0.5(34.50x) = 600 - 65.25. The answer to that would be 31 hair products needed to be sold.

Answer:I would say she is incorrect.

she needs to sell 31

Step-by-step explanation:

her formula gives us $603.75 for a total

She only needs to raise $534.75 ( 600-65.25)

she makes 17.25 (34.50/2)on each sale so 534.75/17.25 =31

0.5(34.50x)=534.75 using the way she wrote it but could be simplier cause we already know she gets 17.25 so 17.25x=534.75 x=31

The length of the deep end is 12 feet of the swimming pool.

Given: Area of the swimming pool is 210 square feet

Width of the pool = 10 feet

The length of the shallow end is 9 feet and the length of the deep end is d.

To find the value of d.

Let's solve the problem.    

The area of the swimming pool is 210

The width is 10

The deep end length is d

The shallow end length is 9

The total length of the swimming pool = The length of the deep end + The length of the shallow end

=> d + 9

Therefore, the total length of the swimming pool is d + 9

The surface of the swimming pool is rectangular, so

The area of rectangle = width × length

Therefore,

area of swimming pool = width of the pool × length of the swimming pool

=> 210 = 10 × (9 + d)

or 10 × (9 + d) = 210

Dividing both sides by 10:

10 × (9 + d) / 10 = 210 / 10

9 + d = 21

Subtracting 9 on both sides:

9 + d - 9 = 21 - 9

d = 12

Therefore the length of the deep end is 12 feet

Hence the length of the deep end is 12 feet of the swimming pool.

Answer:

Area = 587877.54 \(m^{2}\)

Step-by-step explanation:

Let the length of sides of the triangle be represented by a, b and c respectively.

a = \(\frac{5}{18}\) x 3600

  = 1000

b = \(\frac{6}{18}\) x 3600

  = 1200

c = \(\frac{7}{18}\) x 3600

  = 1400

The length of the sides of the triangle are: 1000 m , 1200 m, 1400 m.

Perimeter = a + b + c

               = 1000 + 1200 + 1400

               = 3600

The area of the land can be determined by;

Area of a triangle =  \(\sqrt{(s*(s-a)* (s-b)* (s-c))}\)

where: s is the semi-perimeter of the triangle and a, b and c are the length of sides respectively.

s = \(\frac{perimeter}{2}\)

 = \(\frac{3600}{2}\)

s = 1800

Area = \(\sqrt{(1800(1800 - 1000)*(1800 - 1200)*(1800 - 1400))}\)

        = \(\sqrt{(1800*800*600*400)}\)

        = \(\sqrt{345600000000}\)

Answer:

Step-by-step explanation:

The direct variation equation that relates x ounces to y grams is y = 28.3x, where y represents the number of grams and x represents the number of ounces.

In a direct variation, two variables are directly proportional to each other. In this case, we are relating ounces to grams. The given information states that one ounce is approximately 28.3 grams.

To write a direct variation equation, we can assign y as the number of grams and x as the number of ounces. Since the two variables are directly proportional, we can express the relationship as y = kx, where k is the constant of variation.

From the given information, we know that one ounce is approximately 28.3 grams. Therefore, the constant of variation is 28.3. Substituting this value into the equation, we get y = 28.3x.

This equation indicates that as the number of ounces (x) increases or decreases, the number of grams (y) will vary directly by a factor of 28.3. For example, if we have 2 ounces, we can find the number of grams by multiplying 2 by 28.3, resulting in 56.6 grams.

The series in question is given by S_n = √(n^8 + 9n). The ratio of the terms approaches a finite positive value. We want to determine whether this series converges or diverges using the Limit Comparison Test.

1. To apply the Limit Comparison Test, we choose a known convergent series with positive terms, let's call it b_n. In this case, we can choose b_n = √(n^8).

2. Now, we need to find the limit of the ratio of the terms of the two series as n approaches infinity. We calculate the limit:

lim n→∞ (√(n^8 + 9n) / √(n^8))

Simplifying the expression inside the limit, we have:

lim n→∞ (√(n^8 * (1 + 9/n)) / n^4)

3. Using properties of limits, we can rewrite the expression as:

lim n→∞ (√(n^8) * √(1 + 9/n) / n^4)

Simplifying further, we have: lim n→∞ (n^4 * √(1 + 9/n) / n^4)

4. The n^4 terms cancel out, leaving us with: lim n→∞ √(1 + 9/n)

As n approaches infinity, the term 9/n approaches zero, and we are left with: lim n→∞ √1 = 1

5. Since the limit is finite and positive (L = 1), and the series b_n = √(n^8) converges, we conclude that the original series S_n = √(n^8 + 9n) also converges.

6. In summary, using the Limit Comparison Test, we determined that the series S_n = √(n^8 + 9n) converges. The explanation above shows the step-by-step calculation of the limit, demonstrating that the ratio of the terms approaches a finite positive value.

Given that A and B are nonempty, bounded subsets with A ⊆ B, we can conclude that the infimum of A, denoted as inf(A), will be greater than or equal to the infimum of B, denoted as inf(B).

The infimum of a set is the greatest lower bound, which means it is the smallest element that is greater than or equal to all the elements in the set. Since A is a subset of B, every element in A will also be an element of B. Therefore, any lower bound of B will also be a lower bound of A. This implies that the infimum of B, being the greatest lower bound of B, will also be a lower bound of A. Hence, inf(B) is less than or equal to inf(A).

Therefore, we can conclude that inf(A) ≥ inf(B).

If we assume that sup(A) < inf(B), then there exists an element x in the set A such that x > sup(A) and x < inf(B). Since sup(A) is an upper bound of A, it means that all elements in A are less than or equal to sup(A). However, x violates this condition as it is greater than sup(A), which contradicts the assumption.

Therefore, the assumption that sup(A) < inf(B) is false, and we can conclude that sup(A) ≥ inf(B).
