Express the given quantity as a function f(x) of one variable x. The product of two numbers x and y whose sum is 29 y f(x) II

The correct option representing the function is f(t) = 30,303(0.85)t based on the deprivation rate.

Firstly calculating the depreciation rate -

30,303 - x%×30,303 = 25,757

x×303.03 = 30,303 - 25,757

Performing subtraction on Right Hand Side of the equation

x×303.03 = 4546

x = 4546/303.03

Performing division

x = 15%

The formula to be used for function is -

P = Po\( {(1+r)}^{t} \), where P is the final value, Po is the original value, r is growth rate and t is time.

P = 30,303 \( {(1 - 0.15)}^{t} \)

Performing subtraction on Right Hand Side of the equation

P = 30,303 \( {(0.85)}^{t} \)

The value of car after t years is 30,303 \( {(0.85)}^{t} \).

Year 1 2

Value (in dollars) 25,757.55 21,893.92

Which function best represents the value of the car after t years?

f(t) = 25,757.55(0.85)t

f(t) = 30,303(0.85)t

f(t) = 30,303 (0.15)t

f(t) = 25,757.55 (0.15)t

The book is opened to pages 11 and 12.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

So, the book is opened to pages 11 and 12.

Answer:

It loses -0.04 milliliters per minute.

Step-by-step explanation:

The pipe loses 1 1/5 milliliters (I'mma just call it ml from now on) every 30 minutes. The question is asking how many ml it loses every one minute. To find this, divide 1 1/5 ml by 30. This is very difficult with fractions tho, so convert the fraction into a decimal. (1 1/5 as a decimal is 1.2) Then divide 1.2 by 30 and you get -0.04 ml per minute.

Make sure you put that it loses *negative* 0.04 ml per minute!

The symmetric difference of two sets is the set of elements that are in either of the sets, but not in their intersection. In this case, the intersection of {1, 3, 5} and {1, 2, 3} is {1, 3}, so the symmetric difference is the set of elements that are in either {1, 3, 5} or {1, 2, 3}, but not in {1, 3}. This set is {2, 5}, since 2 is in {1, 2, 3} but not in {1, 3, 5}, and 5 is in {1, 3, 5} but not in {1, 2, 3}. Therefore, the symmetric difference of {1, 3, 5} and {1, 2, 3} is {2, 5}.

Step 1: Identify the two sets.
Set A = {1, 3, 5}
Set B = {1, 2, 3}

Step 2: Find the difference between the two sets.
A - B = {5} (elements in A that are not in B)
B - A = {2} (elements in B that are not in A)

Step 3: Combine the two differences to find the symmetric difference.
Symmetric Difference = A - B ∪ B - A

1.904 mcg/kg/min is what the client receives.

The number of mcg/kg/minute = flow rate × concentration ÷ mass of client

Flow rate = 12 ml/ hour = 12 /60 = 1/5 = 0.2 ml/min

Formula:

Concentration = mass of dopamine/volume

mass of dopamine = 800mg

volume = 500ml

Concentration = 800/ 500

= 1.6 mg/ml

= 1.6 × 1000 mcg/mg

= 1600 mcg/mg

Here the mass of the client = 70kg

Now calculating mcg/kg/minute = flow rate× concentration÷ mass of client

= 0.08 ml/min × 1600mcg/ml ÷70 kg

= 320/70

= 1.904 mcg/kg/min

Function notation is way of writing functions so that they can easily be understood in the mathematical sense. This method is applied in the question to help read the meaning in the question without much explanations.

Given data

f ( x )  =  x^3

c. No   f ( x )   ≠    f ( -x )

f ( x )  =  x^3   and f ( -x )  =  - x^3

f ( x ) is not equal to f ( -x )

plugging the values for the left hand side of the equation gives

x^3

and plugging the values for the right hand side of the equation gives

- x^3

since the left hand side of the equation is not equal to the right hand side of the equation it means that the both sides of the equation are not equal hence equation sated in c is not correct

The mass of the wire is found to be 40π√2 units.

To calculate the mass of the wire which runs along the curve r ( t ) with the density function δ=5.

The general formula is,

Mass = \(\int_a^b \delta\left|r^{\prime}(t)\right| d t\)

To find, we must differentiate this same given curve r ( t ) with respect to t to estimate |r'(t)|.

The given integration limits in this case are a = 0, b = 2π.

Now, as per the question;

The equation of the curve is given as;

r(t) = (4cost)i + (4sint)j + 4tk

Now, differentiate this same given curve r ( t ) with respect to t.

\(\begin{aligned}\left|r^{\prime}(t)\right| &=\sqrt{(-4 \sin t)^2+(4 \cos t)^2+4^2} \\&=\sqrt{16 \sin ^2 t+16 \cos ^2 t+16} \\&=\sqrt{16\left(\sin t^2+\cos ^2 t\right)+16}\end{aligned}\)

Further simplifying;

\(\begin{aligned}&=\sqrt{16(1)+16} \\&=\sqrt{16+16} \\&=\sqrt{32} \\\left|r^{\prime}(t)\right| &=4 \sqrt{2}\end{aligned}\)

Now, use integration to find the mass of the wire;

       \(\begin{aligned}&=\int_a^b \delta\left|r^{\prime}(t)\right| d t \\&=\int_0^{2 \pi} 54 \sqrt{2} d t \\&=20 \sqrt{2} \int_0^{2 \pi} d t \\&=20 \sqrt{2}[t]_0^{2 \pi} \\&=20 \sqrt{2}[2 \pi-0] \\&=40 \pi \sqrt{2}\end{aligned}\)

The statement "When the coefficient of friction gets smaller, tension decreases" is not accurate. The coefficient of friction and tension are not directly related in this way.

Let's break down why this statement is incorrect.
1. Coefficient of friction: The coefficient of friction is a value that represents the interaction between two surfaces in contact. It indicates how easily one surface can slide or move relative to the other. It depends on the nature of the surfaces involved.
2. Tension: Tension is the force transmitted through a string, rope, or any type of flexible connector when it is under tension or being pulled. Tension can exist in various situations, such as when a string is pulled by two objects or when a rope is attached to a hanging weight.
3. Relationship between coefficient of friction and tension: The coefficient of friction affects the force required to overcome frictional resistance between two surfaces. However, it does not directly affect tension.
4. Examples: Let's consider an example to illustrate this. Imagine a block being pulled horizontally by a rope. The tension in the rope is equal to the force being applied to the block. The coefficient of friction between the block and the surface it's on determines the resistance to motion. If the coefficient of friction decreases, the resistance to motion decreases, allowing the block to move more easily. However, the tension in the rope remains the same because it depends on the force being applied, not the coefficient of friction.
In summary, the statement that "when the coefficient of friction gets smaller, tension decreases" is incorrect. The coefficient of friction affects the resistance to motion, but tension is dependent on the applied force and not directly related to the coefficient of friction.

1 standard deviation =  8 inches. the answer is OPTION E

We know that 99.7% of American men have heights between 5'0" and 7'0". Since height is normally distributed, we can use the empirical rule to estimate the standard deviation.

According to the empirical rule, 99.7% of the data falls within 3 standard deviations of the mean. Therefore, we can say that the range of heights from 5'0" to 7'0" is 3 standard deviations.

We can use this information to estimate the standard deviation as follows:

Range of heights = 7'0" - 5'0" = 2 feet

3 standard deviations = 2 feet

1 standard deviation = 2/3 feet

1 foot = 12 inches

Therefore, 1 standard deviation = 2/3 * 12 inches = 8 inches

We want to find the probability that the candidate gets a score greater than or equal to 10, which is equivalent to getting 10 or more questions correct.

Using the normal approximation to the binomial distribution with continuity correction, we can approximate the distribution of the number of correct answers by a normal distribution with mean μ = np = 40 * 1/5 = 8 and variance σ^2 = np(1-p) = 40 * 1/5 * 4/5 = 6.4.
