Answer:

D. 6 1/12

Step-by-step explanation:

First add the like fractions.

3 2/3 + 2/3 = 3 4/3 (Don't worry about simplifying yet)

Now find the least common multiple for 3 4/3 and 1 3/4 so we can add them.

3: 3, 6,  9, 12

4: 4, 8, 12

In this case 12 is the least common multiple.

3/4 x 3/3 = 9/12    9/12

4/3 x 4/4 = 16/12

Add those two fractions then add the whole numbers and put it in front.

The translation of the points S(-3, 3), C(-1, 4), and W(-2, -1) is S(3, 0), C(5, 1), and W(4, -4) after moving 6 units to the right and 3 units down.

The translation of a point involves shifting it horizontally (right or left) and vertically (up or down) by a certain number of units. In this case, we are asked to perform a translation of 6 units right and 3 units down.

Original Points:

1. S(-3, 3)

2. C(-1, 4)

3. W(-2, -1)

Translation process:

1. For the point S(-3, 3):

  - Move 6 units to the right: x-coordinate becomes -3 + 6 = 3

  - Move 3 units down: y-coordinate becomes 3 - 3 = 0

  So, the translated point S(3, 0).

2. For the point C(-1, 4):

  - Move 6 units to the right: x-coordinate becomes -1 + 6 = 5

  - Move 3 units down: y-coordinate becomes 4 - 3 = 1

  So, the translated point C(5, 1).

3. For the point W(-2, -1):

  - Move 6 units to the right: x-coordinate becomes -2 + 6 = 4

  - Move 3 units down: y-coordinate becomes -1 - 3 = -4

  So, the translated point W(4, -4).

After the translation, the new coordinates for each point are as follows:

1. S(3, 0)

2. C(5, 1)

3. W(4, -4)

These are the points obtained after moving each original point 6 units to the right and 3 units down.

Answer:

We know that:

y = -5.797

x = 4.0

and:

k/y = p/x + 1

We can rewrite this as:

k = (p/x + 1)*y = p*(y/x) + y

Replacing the values of x and y, we get:

k = p*(-5.797/4.0) + (-5.797)

We could simplify this to get:

k = p*(-1.44925) - 5.797

So we ended with a linear equation, so for a given value of p, we know the k.

Now, we could solve this if we add the restriction that k and p must be integers.

Then we can return to:

k = (p/x + 1)*y = (p + x)*(y/x)

replacing the values we get:

k = (p + 4.0)*(-5.797/4.0)

if p = 3996, then p + 4 = 4000

and 4000*(-5.797/4.0) = 1000*(-5.797) = -5797

Then if we take p = 3996, k will also be an integer:

k = (3996 + 4.0)*(-5.797/4.0) = -5797

Then:

p = 3996

k = -5797

is a possible solution of the problem.

Answer:

Step-by-step explanation:

To make the 2% solution of tetracaine hydrochloride isotonic, a 0.9% solution of sodium chloride should be used.

The amount of the 0.9% sodium chloride solution needed can be calculated by setting up a proportion based on the concentration percentages.

Let's assume x represents the volume of the 0.9% sodium chloride solution needed in milliliters.

Since the 0.9% solution is isotonic, it means that the concentrations of tetracaine hydrochloride and sodium chloride should be equal. Therefore, the proportion can be set up as follows:

(0.9 / 100) = (2 / 100) * (x / 30)

Simplifying the proportion, we have:

0.009 = 0.02 * (x / 30)

To solve for x, we can multiply both sides of the equation by 30 and divide by 0.02:

x = (0.009 * 30) / 0.02

x ≈ 13.5 mL

Therefore, approximately 13.5 milliliters of the 0.9% sodium chloride solution should be used in compounding the prescription to make the 2% tetracaine hydrochloride solution isotonic.

The derivative of the given function  in the form sum or difference is given by, g' (x) = 24 x³ - 7

Given the function is,

g (x) = [6 x⁶ - 7 x³]/x²

g (x) = (6 x⁶)/x² - (7 x³)/x²

g (x) = 6 x⁶⁻² - 7 x³⁻², since the division in exponential means subtraction of powers.

g (x) = 6 x⁴ - 7 x

Differentiating the simplified above function with respect to the variable 'x' we get,

d/dx [g (x)] = d/dx [6 x⁴ - 7 x]

g' (x) = d/dx (6 x⁴) - d/dx (7 x)

g' (x) = 6 d/dx (x⁴) - 7 d/dx (x)

g' (x) = 6 (4 x³) - 7 * 1

g' (x) = 24 x³ - 7

Hence the derivative of the function is, g' (x) = 24 x³ - 7.

The variables of farmer are independent variables and dependent variables.

In this scenario, the farmer is testing the impact of different amounts of nitrogen on corn plant height. Her variables are as follows:

1. Independent variable: The amount of nitrogen infused in the soil (one pot has nitrogen-infused soil and the other has regular soil).

2. Dependent variable: The height of the corn plants (measured in feet).

However, it's important to note that the experimental setup has a potential confounding variable, which is the location of the pots (one is outside and the other is in the bathroom). This might influence the results and make it difficult to solely attribute the differences in height to the nitrogen content in the soil.

Answer: Let's use some algebra to solve the problem.

Let x be the number of hamburgers sold on Sunday. Then, the number of cheeseburgers sold is 50 less than x, which we can represent as (x - 50).

The total number of hamburgers and cheeseburgers sold is 450, so we can set up an equation:

x + (x - 50) = 450

Simplifying the left side:

2x - 50 = 450

Adding 50 to both sides:

2x = 500

Dividing by 2:

x = 250

So, 250 hamburgers were sold on Sunday.

To check, we can calculate the number of cheeseburgers sold:

x - 50 = 250 - 50 = 200

And indeed, the total number of hamburgers and cheeseburgers sold is 250 + 200 = 450.

Answer:

\(a_{n}\) = 3 \((-2)^{n-1}\)

Step-by-step explanation:

there is a common ratio between consecutive terms , that is

- 6 ÷ 3 = 12 ÷ - 6 = - 24 ÷ 12 = 48 ÷ - 24 = - 2

this indicates the sequence is arithmetic with explicit rule

\(a_{n}\) = a₁ \((r)^{n-1}\)

where a₁ is the first term and r the common ratio

here a₁ = 3 and r = - 2 , then

\(a_{n}\) = 3 \((-2)^{n-1}\)

Answer:

\(\sf \dfrac{-3}{2}(-2)^n\)

Step-by-step explanation:

Explicit formulas are used to represent all the terms of the geometric sequence with a single formula.

  \(\sf \boxed{\bf t_n = ar^{n-1}}\)

a is the first term.

r is the common ratio.

r = second term ÷ first term.

   3 , - 6 , 12, - 24, 48 ,........

a = 3

r = -6 ÷ 3 = -2

         \(\sf t_n = 3*(-2)^{(n-1)}\\\\\)

             \(\sf = 3*(-2)^{n}*(-2)^{-1}\\\\ =3*(-2)^n*\dfrac{-1}{2}\\\\= \dfrac{-3}{2}(-2)^n\)

Check:

\(\sf t_1 =\dfrac{-3}{2}*(-2)^1=\dfrac{-3}{2}*(-2) = 3\\\\\\t-2 = \dfrac{-3}{2}*(-2)^2 = \dfrac{-3}{2}*4=-6\\\\\\t_3=\dfrac{-3}{2}*(-2)^3=\dfrac{-3}{2}*(-8)=12\)

The median of the following set of numbers  (18, 26, 29, 18, 44) is 26. The correct option to this question is option A

To find median of the following sequence (18, 26, 29, 18, 44) we will arrange them in ascending order

                            18 , 18 , 26 , 29 , 44   . . . . . .  . . . .(1)

Since the number of terms is odd we will apply the formula

                     Median  = \(\frac{(n+1)}{2} th\) term . . . . . . .(2)

       Here n = number of terms

As per question the n = 5

Therefore putting in equation 2 we get

                      Median = \(\frac{(5+1)}{2} th\) term

                      Median = \(\frac{6}{2} th \\\)  term

                      Median = 3 term

Hence the third term from the sequence ( shown in 1 ) we get the median that is 26

Given that the radius of the sprinkler's spray is 22ft, we can substitute this value into the formula:

A = 3.14 * (22)^2

A ≈ 3.14 * 484

A ≈ 1519.76

The minimum number of choices in a scoring procedure that the student must eliminate before it is advantageous to guess among the rest is 4. Option E is the correct option.

Suppose that there are n choices remaining for a particular question.

The probability of answering this question correctly is 1/n if the student guesses and the probability of leaving the question unanswered is (n-1)/n.

The expected score for guessing is therefore (7/n) × (1/n) + (2/n) × ((n-1)/n) = (7 + 2(n-1))/n² = (9 - 2/n)/n.

The expected score for leaving the question unanswered is 2/n.

The student should guess if and only if the expected score for guessing is greater than the expected score for leaving the question unanswered.

That is, we must have (9 - 2/n)/n > 2/n, or equivalently 9 > 2n, or n < 4.5.

Thus, if the number of choices remaining is 4 or more, the student should not guess; if the number of choices remaining is 3 or fewer, the student should guess.

Answer:

angle CED 90°. CE = 21. EB = 8.

Step-by-step explanation:

angle CED = 90° (right angle).

the radius (centre to edge) is the same right around the circle.

so that means that distance CD = 29.

draw a line from C to D. notice how that has just become an hypotenuse?

we know that DE = 20.

we have a right-angled triangle.

CE² = hypot² - DE²

       = 29² - 20²

       = 841 - 400

       = 441

CE = √441 = 21.

EB must be radius subtract CE. that is, 29 - 21 = 8.
