let p be defined as in the previous problem. is ∀x∃y∃z(y 6= z → p(x, y) ∧ p(x, z)) true or false? explain.

Answer:

D

Step-by-step explanation:

The correct answer is D. −0.6; for every additional hour, the length of the icicle decreases by 0.6 inches.

The slope of a line represents the rate of change of one variable with respect to the other variable. In this case, the length of the icicle (y) is changing with respect to time (x). The slope of the line represents the change in the length of the icicle (y) for every additional hour (x).

Since the icicle is melting at a rate of 0.6 inches per hour, the length of the icicle decreases by 0.6 inches for every additional hour. The slope of the line representing this relationship is -0.6. This means that for every additional hour, the length of the icicle decreases by 0.6 inches.

Answer:

8 and 1/3

Step-by-step explanation:

First, let's understand the situation. There is a 25 oz juice that is to be split 3 ways. To determine the amount of jucie each person gets, we will take the total amount of juice and divide it by the number of kids, 3. When we do this, we get 25/3. Since this fraction can;t be simplified into a whole number, we will need to turn 25/3 into a mixed number. To do this, we need to know how many times 3 goes into 25. 3 goes into 25 8 times with a remainder of 1. This remainder is put over 3, giving us the final answer, 8 and 1/3.

At the lowest temperature he could get a water and salt solution to attain, Fahrenheit set zero.

Fahrenheit is named for German scientist Daniel Gabriel Fahrenheit, who was born there in 1686 as part of the Polish-Lithuanian Commonwealth. He was the first to develop a constant, accurate method of measuring temperature. At the lowest temperature he could get a water and salt solution to attain, Fahrenheit set zero.

To assist us remember that we go from colder to hotter as we walk up the scale on our thermometer, let's label it. In other terms, a higher number of degrees Fahrenheit is hotter than a lower number.

[tex]$$\begin{aligned}& \text { Given:- } \mathrm{C}=\frac{5}{9}(\mathrm{~F}-32) \\& \Rightarrow \mathrm{F}=\frac{9}{5} \mathrm{C}+32\end{aligned}$$[/tex]

(I) If [tex]$F^{\prime}=F+1$[/tex]

[tex]$$\begin{aligned}\mathrm{C}^{\prime} & =\frac{5}{9}\left(\mathrm{~F}^{\prime}-32\right) \\\mathrm{C}^{\prime} & =\frac{5}{9}(\mathrm{~F}+1-32) \\\mathrm{C}^{\prime} & =\frac{5}{9}(\mathrm{~F}-32)+\frac{5}{9} \times 1 \\\mathrm{C}^{\prime} & =\mathrm{C}+\frac{5}{9}\end{aligned}$$[/tex]

Hence, a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of [tex]$\frac{5}{9}$[/tex] degree Celsius.

Therefore, statement I exists true.

(II) If [tex]$\mathrm{C}^{\prime}=\mathrm{C}+1$[/tex]

[tex]$$\begin{aligned}& \mathrm{F}^{\prime}=\frac{9}{5} \mathrm{C}^{\prime}+32 \\& \mathrm{~F}^{\prime}=\frac{9}{5}(\mathrm{C}+1)+32 \\& \mathrm{~F}^{\prime}=\left(\frac{9}{5} \mathrm{C}+32\right)+\frac{9}{5} \\& \mathrm{~F}^{\prime}=\mathrm{F}+\frac{9}{5} \\& \mathrm{~F}^{\prime}=\mathrm{F}+1.8\end{aligned}$$[/tex]

Therefore, a temperature increase of 1 degree Celsius exists equivalent to a temperature increase of 1.8 degrees Fahrenheit.

Therefore, statement II exists true.

[tex]$$\begin{aligned}& \text { (III) If } F^{\prime}=F+\frac{5}{9} \\& C^{\prime}=\frac{5}{9}\left(F^{\prime}-32\right) \\& C^{\prime}=\frac{5}{9}\left(F+\frac{5}{9}-32\right) \\& C^{\prime}=\frac{5}{9}(F-32)+\frac{5}{9} \times \frac{5}{9} \\& C^{\prime}=C+\frac{25}{81}\end{aligned}$$[/tex]

Therefore, a temperature increase of [tex]$\frac{5}{9}$[/tex] degree Fahrenheit exists equivalent to a temperature increase of [tex]$\frac{25}{81}$[/tex] degree Celsius.

The equation 3x = 6.4 can be solved for x by dividing both sides of the equation by 3: 3x/3 = 6.4/3; x = 2.13

So, for 3x and 6.4x to be equal, x must be equal to 2.13. This means that you need to multiply the number 6.4 by 2.13 to equal 3. The equation 3x = 6.4 represents the relationship between two variables, x and 3x. We are trying to find the value of x that would make 3x equal to 6.4. To do this, we divide both sides of the equation by 3. Dividing both sides of an equation by the same number does not change the relationship between the variables; it only scales down the variable's value by the same factor.

So, by dividing both sides of the equation by 3, we get:

3x/3 = 6.4/3

x = 2.13

Finally, to make 6.4x equal to 3, we need to divide 6.4 by 2.13: 6.4 / 2.13 = 3. So, we need to multiply 6.4 by 2.13 to equal 3.

f(-5) = 42

f(0) = 7

f(1) = 6

A function is a relationship that has a set of inputs and outputs. An example of a function is f(x) = x. The "(x)" in the parenthesis represents the input while the x on the left side represents the output. To compute the values of an output you plug in the input and replace all the variables with the input. E.g. to find f(1) we would replace all "x"s with 1 giving us f(1) = 1

Given f(x) = x² - 2x + 7 we want to find f(-5) , f(0) and f(1)

We can find these values by simply plugging in the values of the inputs and replacing all x's for them.

If f(x)= x² - 2x + 7

Then,

f(-5) = (-5)² - 2(-5) + 7                                                             simplify exponents

f(-5) = 25 - 2(-5) + 7                                                                  multiply -2 and -5

f(-5) = 25 + 10 + 7                                                                           add all values

f(-5) = 42

f(0) = (0)² - 2(0) + 7                                                                 simplify exponents

f(0) = 0 - 2(0) + 7                                                                       multiply 0 and -2

f(0) = 0 - 0 + 7                                                                                 add all values

f(0) = 7

f(1) = (1)² - 2(1) + 7                                                                     simplify exponent

The definite integral of the function (2x - 3) with respect to x can be found using the antiderivative, also known as indefinite integration.

The antiderivative of (2x - 3) is:

x^2 - 3x + C, where C is the constant of integration.

For the definite integral, we need to find the antiderivative over a given interval. To calculate the definite integral, we need to evaluate the antiderivative at the limits of the interval and subtract the values.

So, for example, if the interval is from a to b, the definite integral is given by:

∫_a^b (2x - 3) dx = (x^2 - 3x) |_a^b = (x^2 - 3x) evaluated at b - (x^2 - 3x) evaluated at a.

The definite integral of the function y³ (2y² – 3) with respect to y can be found in a similar way. The antiderivative of y³ (2y² – 3) can be found using power rule of integration.

The antiderivative of y³ (2y² – 3) is:

(1/4) y⁴ - 3y² + C, where C is the constant of integration.

The definite integral of the function can then be found by evaluating the antiderivative at the limits of the interval and subtracting the values, as described above.

The translated points are P' ( -2 , 3 ) and Q' ( 3 , 7 )

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the points be represented as P and Q

Now , the coordinates of point P = P ( 0 , 0 )

And , the coordinates of the point Q = Q ( 5 , 4 )

when the points are translated up 3 units and left 2 units

The coordinates of the translated point will be ( x , y ) to ( x - 2 , y + 3 )

Substituting the values in the equation , we get

The coordinates of the translated point P' = P' ( -2 , 3 )

The  probability that x is within 1 standard deviation from its mean value is 0.68.

Probability is the measure of the likelihood of an event occurring. In statistics, it is used to describe the chance of a particular value falling within a certain range.

A standard deviation is a measure of the spread of a set of data from its mean.

Typically, 68% of the data falls within 1 standard deviation from the mean, 95% falls within 2 standard deviations, and 99.7% falls within 3 standard deviations.

In order to find the probability that x is within 1 standard deviation from its mean value, we need to use a normal distribution.

In a normal distribution, 68% of the data falls within 1 standard deviation from the mean.

So, in this case, the probability that x is within 1 standard deviation from its mean value is 0.68 or 68%.

There is a 68% chance that a repair claim will be between $40 and $1020.

The normal distribution is a continuous probability distribution that is symmetric around the mean, with mean and variance being the same. In this case, the mean is $530 and the standard deviation is $490. This means that the repair claims are normally distributed, with the majority of the claims being between $530-$490 and $530+$490. This gives us a range of $40-$1020.

The normal distribution is often used to describe random variables because it is the most common probability distribution. In this case, it implies that the repair claims are randomly distributed around the mean of $530. The standard deviation of $490 indicates that there is a 68% chance that a repair claim will be within one standard deviation of the mean. In this case, that means that there is a 68% chance that a repair claim will be between $40 and $1020.

Not sure this is the easiest way

line BC equation is    y = - 2/9x + 3 7/9

 perpindicular line that includes point A (2,1) has slope 9/2

    point slope form would be

            y-1 = 9/2(x-2)      re-arranged to y = mx+b form

            y = 9/2 x -8

to find the actual altitude , these two lines intersect.....equate them

-2/9x + 3 7/9 = 9/2 x- 8

    11 7/9  = 4 13/18 x

                 x = 2 42/85        then y = 3 19/85

altitude then (using distance formula)

  a^2 = (2 42/85 -2)^2  + (1- 3 19/85)^2  

                     a = 2.278 units

I hope this answered the question....I am not sure what 'the equation of the altitude'  means

The equation of the altitude of the triangle is y = ( 9/2 )x - 8

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be B ( -1 , 4 )

Let the second point be C ( 8 , 2 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope m = ( 4 - 2 ) / ( -1 - 8 )

m = -2/9

Now , the slope of the altitude is m₂ = 9/2 ( perpendicular lines have negative reciprocal slope )

And , the altitude passes through the point A ( 2 , 1 )

So , the equation of line is y - y₁ = m ( x - x₁ )

y - 1 = ( 9/2 ) ( x - 2 )

y - 1 = ( 9/2 )x - 9

Adding 1 on both sides , we get

y = ( 9/2 )x - 8

Hence , the equation of line is y = ( 9/2 )x - 8

The average rate of change of V with respect to r over the interval [85,110] is 0.76 meters cubed per year per centimetre of rainfall.

V(r) = 0.2r² − 20r + 600

The average rate of change of V with respect to r over the interval [85,110] can be calculated by finding the derivative of V(r) and evaluating it at the midpoint of the interval, then dividing the result by the length of the interval. The derivative of V(r) is:

dV/dr = 0.4r - 20

The midpoint of the interval [85,110] is (85 + 110)/2 = 97.5. Evaluating the derivative at the midpoint, we get the following:

dV/dr = 0.4 × 97.5 - 20 = 19.0

The length of the interval is 110 - 85 = 25, so the average rate of change is:

The average rate of change = (dV/dr)/(110 - 85) = 19.0/25 = 0.76

110° + 7x° = 180°

Collect the like terms -

7x° = 180° - 110°

Apply the arithmetic operation of subtraction -

7x° = 70°

Apply the arithmetic operation of division -

x = 70/7

x = 10°

Now the angle 7x° = 7(10°) = 70°

Therefore, the angle value is obtained as 70°.
