Tyler swam for 230 minutes during his first week of vacation. In his two weeks of vacation, he swam for a total of 539 minutes. How many more minutes did he swim for in the second week than in the first week?

I assume the limit you're asked to copmute is supposed to be

[tex]\displaystyle \lim_{x\to5} \frac{\sqrt{x+4}-3}{x-5}[/tex]

Rationalize the numerator by multiplying it by its conjugate:

[tex]\dfrac{\sqrt{x+4}-3}{x-5} \times \dfrac{\sqrt{x+4}+3}{\sqrt{x+4}+3} = \dfrac{\left(\sqrt{x+4}\right)^2-3^2}{(x-5) \left(\sqrt{x+4}+3\right)} = \dfrac{x-5}{(x-5) \left(\sqrt{x+4}+3\right)}[/tex]

Since x is approaching 5, we have x ≠ 5 and can cancel the factors of x - 5 to remove the discontinuity.

Then

[tex]\displaystyle \lim_{x\to5} \frac{\sqrt{x+4}-3}{x-5} = \lim_{x\to5} \frac1{\sqrt{x+4}+3} = \frac1{\sqrt9+3} = \boxed{\frac16}[/tex]

because the simplified limand is continuous at x = 5.

"I've asked you a million times to please close the back door," said Jade's mother.

A million times is the exaggerated phrase in the sentence. Jade's mother did not really ask her that a million times, but it is used in this sentence as a way to show the reader that she said it a lot.

I guess you mean it is

12 cm long, 4cm wide and 5 cm high.

and the fabric goes outside on the box ? strange, but ok.

a box (like a die) has 6 sides in the form of 3 pairs of equal rectangles :

top-bottom, left-right, front-back

the surface area is the sum of all 6 rectangles.

top-bottom :

2 × 12×4 = 2 × 48 = 96 cm²

left-right :

2 × 4×5 = 2 × 20 = 40 cm²

front-back :

2 × 12×5 = 2 × 60 = 120 cm²

in total

120 + 40 + 96 = 256 cm²

Answer:

Step-by-step explanation:

The probability that a person has a positive rh factor given that he/she has type O blood is approximately 82.2 %

For two events A and B:

The chain rule states that the probability that A and B both occur is given by:

[tex]P(A \cap B) = P(A)P(B|A) = P(B)P( A|B)[/tex]

Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] and some values of Y are there as [tex]Y_1, Y_2, ... , Y_n[/tex]

List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:

Value(ith row, jth column) = Frequency for intersection of  [tex]X_i[/tex] and [tex]Y_j[/tex] (assuming X values are going in rows, and Y values are listed in columns).

Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.

For n = 2, and k = 2, the table would look like:

[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]

where S denotes total of totals, also called total frequency.

n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.

The missing two-way table for this problem is given below:

[tex]\begin{array}{cccccc}&A&B&AB&O&\rm Total\\\text{Negative}&0.07&0.02&0.01&0.08&0.18\\\text{Positive}{&0.33&0.09&0.03&0.37&0.82\\\rm Total & 0.40&0.11&0.04&0.45&1 \end{array}[/tex]

Instead of frequencies, it contains ratio of frequency to total count of people surveyed (thus, relative frequency).

We want the probability that a person has a positive rh factor given that he/she has type O blood.

If we take:

E = event that a random person chosen has a positive rh factor

and F = event that a random person chosen has type O blood

Then, the needed probability is written symbolically as:

P(E|F).

Using the considered two-way table and the chain rule, we get this probability as:

[tex]P(E|F) = \dfrac{P(E \cap F)}{P(F)} = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)}[/tex]

Since the two way table consists relative frequency with total count, so, we get:

[tex]n(E \cap F)/n(Total) = 0.37\\n(F)/n(Total) = 0.45[/tex]

[tex]P(E|F) = \dfrac{n(E \cap F)/ n(Total)}{n(F)/n(Total)} = \dfrac{0.37}{0.45} \approx 0.822 = 82.2\%[/tex]

Thus, the probability that a person has a positive rh factor given that he/she has type O blood is approximately 82.2 %

Answer:

70% of 18 < to 80% of 70

Step-by-step explanation:

70% of 18 is 12.6, and 80% of 70 is 56. So 12.6 < 56.

To get the calculations I did .70 x 18 and then .80 x 70

When the bill came, she would need to pay Millersburg sales tax of 8% and would want to leave a 15% tip on the original $300. Including tax and tip, Camilla's meal cost $369.

Given that,

Original Meal Cost: $300

Sales Tax: 8% of the original meal cost

Tip: 15% of the original meal cost

Total Cost: Sum of the original meal cost, sales tax, and tip

Original Meal Cost = $300

Sales Tax = 8% of $300 = 0.08 * $300 = $24

Tip = 15% of $300 = 0.15 * $300 = $45

Total Cost = Original Meal Cost + Sales Tax + Tip

Total Cost = $300 + $24 + $45 = $369

Including tax and tip, Camilla's meal cost $369.

Step-by-step explanation:

it makes the most sense

option D is correct.

Explanation:

[tex]\rightarrow \sf f(x) = 2x-9[/tex]

To find inverse, make x the subject

[tex]\rightarrow \sf f(x)+9 = 2x[/tex]

[tex]\rightarrow \sf x = \dfrac{ f(x)+9}{2}[/tex]

So the inverse is:

[tex]\rightarrow \sf g(x) = \dfrac{ x+9}{2}[/tex]

Rest all options are incorrect and is not inverse of each other.

Using the Factor Theorem, it is found that yes, it is possible for a sixth degree polynomial function with integer coefficients to have no real zeroes, as they can have three complex-conjugate pairs.

The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient.

If a complex number is a root of a function, it's conjugate will also be a root. Thus, with three pairs of complex-conjugate roots, for example, [tex]\pm i, \pm 2i, \pm 3i[/tex], a sixth degree function with no real zeros is formed, so the answer is Yes.

Step-by-step explanation:

I did the math on it.

Answer:

3. 9 (6/12)

4. 4 (3/12)

Step-by-step explanation:

Question 3:

6 (2/6) × 1 (1/2)

multiply the whole number by the denominator

6 x 6 = 36 + 2 (numerator) = 38/6

2 x 1 = 2 + 1 = 3/2

(38/6) x (3/2)

multiply (3/2) by 3

3 x 3 = 9

2 x 3 = 6

38/6 x 9/6

38 x 9 = 342

6 x 6 =  36

19/2 = 9 (1/2) or 9 (6/12)

Question 4:

5 (2/3) × (3/4)

15 + 2 = 17

17/3 x 3/4

17 x 4 = 68

3 x 4 = 12

3 x 3 = 9

4 x 3 = 12

(68/12) x (9/12)

68 x 9 = 612

12 x 12 = 144

612/144 = 4 (1/4) or 4 (3/12)

Answer:

0.7.

Step-by-step explanation:

x^2 = 0.7x

x^2 - 0.7x = 0

x(x - 0.7) = 0

x = 0, 0.7.

After solving the quadratic equation x² = 0.7x , we get that the original number is 0.7

Quadratic equation is an equation which contains one unknown variable and the highest power of this unknown variable is 2. Let x be the unknown variable then the standard quadratic equation in x is given by

ax²+bx+c =0, where a, b, c are constants and a≠0

We can  solve this equation by factorizing ax²+bx+c and  putting those factors equal to zero to solve for x.

Let a non zero number be x, x≠0 and given that the square of a non zero number is equal to the 70% of the original number.

As 70 % of the original number = 70/100(x) = 0.7 x

⇒ x² = 0.7 x

⇒x²-0.7 x = 0

⇒ x(x -0.7)= 0

⇒ x =0 and x - 0.7 = 0

⇒  x = 0.7, as we have given that x is a non zero number

Therefore, the original number is 0.7
