Answer:

  -(√2)/2

Step-by-step explanation:

The expression evaluated at n=a gives the indeterminate form 0/0, so L'Hopital's rule can be used to find the limit. The second expression comes from differentiating numerator and denominator. Then the form with n=a is no longer indeterminate.

  [tex]\displaystyle\lim_{n\to a}{\frac{\sqrt{2n}-\sqrt{3n-a}}{\sqrt{n}-\sqrt{a}}}=\lim_{n\to a}{\frac{\frac{2}{2\sqrt{2n}}-\frac{3}{2\sqrt{3n-a}}}{\frac{1}{2\sqrt{n}}-0}}\\\\=\sqrt{a}\left(\frac{2}{\sqrt{2a}}-\frac{3}{\sqrt{3a-a}}}\right)=\boxed{-\frac{1}{\sqrt{2}}}[/tex]

Step-by-step explanation:

boys : girl

480: 576

Divide each side by 96

480/96 : 576/96

5 : 6

Boys = 576

Girl = 480

Now , dividing both numbers by GCF.

Formula-

If a set has “n” elements, then the number of subset of the given set is 2n and the number of proper subsets of the given subset is given by 2n-1. Consider an example, If set A has the elements, A = {a, b}, then the proper subset of the given subset are { }, {a}, and {b}

Symbol that can be used-

The symbol "⊆" means "is a subset of". The symbol "⊂" means "is a proper subset of".

Step-by-step explanation:

Answer and Step-by-step explanation:

I think the answer is 48.

We should add the 12 and 4, then multiply by 3. The 16 times 3 is to get the original amount of candies. To check, we go through the process using the number 48.

48 times 1/3 is 16. 4 of them are given to the brother, which leaves us with 12 remaining candies.

Answer:

The sum of 4 consecutive odd number is 80

Let X be the first of these numbers

Then the next odd number is X+2

The third is X+4The fourth is X+6

All of these add up to 80

(X) + (X+2) + (X+4) + (X+6) = 80

Using the commutative and associative laws, let's transform this equation into

(X + X + X + X) + (2 + 4 + 6) = 804X + 12 = 80

Subtract 12 from both sides of the equation gives4X = 68

Divide both sides by 4 gives

X = 17

Going back to the original question:What are the 4 consecutive odd numbers: 17, 19, 21, 23Checking our answer:17 + 19 + 21 + 23 = 80 Correct!

Answer:

C. 10,080

Step-by-step explanation:

We can multiply to find how many minutes there are in 1 day.

24 * 60 = 1,440

Now, we can multiply that value by 7 to find out how many minutes there are in 1 week.

1,440 * 7 = 10,080

Answer:

33 cases of oil

Step-by-step explanation:

You start with 100 gallons of oil.

1 gallon = 4 quarts

100 gallons = 100 * 4 quarts

100 gallons = 400 quarts

You start with 400 quarts.

You place 12 quarts in each box.

400/12 = 33 1/3

You can pack 33 full cases plus 1/3 of another case.

The question only askes about full cases.

Answer: 33 cases of oil

The number of cases of oil will be 8 cases of oil. Then the correct option is A.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

It is your responsibility to fill quart-size oil bottles from a 100-gallon oil tank at work. The next step is to prepare a case to transport 12 quarts of oil to a retailer.

The number of cases of oil that you can get from a full 100-gallon tank of oil will be given as,

⇒ 100 / 12

⇒ 8.33

⇒ 8 cases of oil

Thus, the correct option is A.

The question given above will require a good understanding of surd operation in order to arrive at the best answer. Thus, the answer to the question is:

[tex]\frac{7\sqrt{14} }{\sqrt{7}} = 7\sqrt{2}[/tex]

To solve this problem, we shall simply rationalise the denominator. This can be obtained as illustrated below:

[tex]\frac{7\sqrt{14}}{\sqrt{7}}\\\\Rationalise\\\\\frac{7\sqrt{14}}{\sqrt{7}} * \frac{\sqrt{7} }{\sqrt{7}}\\\\\frac{7\sqrt{14*7}}{\sqrt{7*7}}\\\\\frac{7\sqrt{98}}{\sqrt{49}}\\\\\frac{7\sqrt{98}}{7}\\\\\sqrt{98}\\\\\sqrt{98} = \sqrt{49*2} \\\sqrt{98} = \sqrt{49} * \sqrt{2} \\\sqrt{98} = 7\sqrt{2} \\\\Thus, \\\\\frac{7\sqrt{14}}{\sqrt{7}} = 7\sqrt{2}[/tex]

Step-by-step explanation:

3x+8x - 3 = -25

Combine like terms

11x -3 = -25

Add 3 to each side

11x -3+3 = -25+3

11x = -22

Answer:

x=-3 and x=4

Step-by-step explanation:

Since x=-2 is a zero of the function, we can find the other two factors by dividing f(x) by (x+2) using long division to obtain the other two roots. The quadratic obtained is x^2-x-12. Now factorising this quadratic will result in (x-4)(x+3)=0, x=-3 and 4 are the other rrots

The factorization of the function f(x) = x³ + x² - 14x - 24​ will be (x + 2), (x + 3), and (x - 4).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The function is given below.

f(x) = x³ + x² - 14x - 24​

Factorize the function, then we have

f(x) = x³ + x² - 14x - 24​

f(x) = x³ + x² - 14x - 24

f(x) = x³ + 2x² - x² - 2x - 12x - 24

f(x) = x²(x + 2) - x(x + 2) - 12(x + 2)

f(x) = (x + 2)(x² - x - 12)

f(x) =(x + 2)(x² - 4x + 3x - 12)

f(x) = (x + 2)[x(x - 4) + 3(x - 4)]

f(x) = (x + 2)(x + 3)(x - 4)

The factorization of the function f(x) = x³ + x² - 14x - 24​ will be (x + 2), (x + 3), and (x - 4).

Answer:

15

Step-by-step explanation:

Complementary angles add to 90 degrees

8x+27 + 6x-21 = 90

Combine like terms

14x+6 = 90

Subtract 6 from each side

14x+6-6 = 90-6

14x = 84

Divide by 14

14x/14 = 84/14

x=6

We want angle B

B = 6x-21 = 6*6-21 =36-21 = 15

[tex]\frac{11z}{z+3}=13-i,z\in\mathbb{C}[/tex]

First, multiply both sides by [tex]z+3[/tex],

[tex]11z=(13-i)(z+3)[/tex]

[tex]13z+39-iz-3i=11z[/tex]

Collect terms and put z on the left,

[tex]2z-iz=3i-39[/tex]

[tex]z(2-i)=3i-39[/tex]

[tex]z=\frac{3i-39}{2-i}[/tex]

Division of complex numbers is defined by multiplying both denominator and numerator with complex conjugate of the denominator,

[tex]z=3\frac{(i-13)(2+i)}{(2-i)(2+i)}[/tex]

Multiply out,

[tex]z=3\frac{2i-1-26-13i}{5}[/tex]

[tex]z=3\frac{-11i-27}{5}[/tex]

The result is,
