\(density = \frac{mass}{volume} \\ volume = \frac{mass}{density} \\ changing \: 1.8 {gcm}^{ - 3} to \: {kgm}^{ - 3} \\ multiply \: by \: 1000 \\ = 1800 {kgm}^{ - 3} \\ volume = \frac{3.1}{1800} \\ = 0.00172 {m}^{ 3} \)

The volume of 3.1 kg of concentrated sulfuric acid is 1722.22 \(cm^{3}\).

Here's the solution:

The density of concentrated sulfuric acid is 1.8 g/\(cm^{3}\). This means that 1.8 grams of concentrated sulfuric acid will occupy 1 cubic centimeter of space.

If we have 3.1 kg of concentrated sulfuric acid, then we have 3100 grams of concentrated sulfuric acid.

The volume of this amount of concentrated sulfuric acid will be:

volume = mass / density

volume = 3100 g / 1.8 g/\(cm^{3}\)

volume = 1722.22 \(cm^{3}\)

Therefore, the volume of 3.1 kg of concentrated sulfuric acid is 1722.2\(cm^{3}\)

Using the given equations Fz = 0, Fy = dz/dx, and Fz = dz/dy, we can find the values of dz/dx and dz/dy at the point (3,4,3) for the equation F(x,y,z) = 22 - 5xy + 3y^2 + 3y^3 - 195 = 0.

Given the equation F(x,y,z) = 22 - 5xy + 3y^2 + 3y^3 - 195 = 0, we need to find dz/dx and dz/dy at the point (3,4,3).

We start by differentiating the equation with respect to z:

Fz = 0.

Next, we use the equations Fy = dz/dx and Fz = dz/dy to find the values of dz/dx and dz/dy.

At the point (3,4,3), we substitute the values into the equations:

Fy = dz/dx |(3,4,3),

Fz = dz/dy |(3,4,3).

Evaluating these equations at (3,4,3), we can find the values of dz/dx and dz/dy. However, without the specific expressions for Fy and Fz, it is not possible to provide the exact numerical values or simplified fractions for dz/dx and dz/dy at (3,4,3) in this case.

To prove the logical equivalences without using truth tables, we will use logical reasoning and the laws of logic, such as the law of implication and the law of conjunction.

(a) ((p → q) → p) = T

To prove this logical equivalence, we can use the law of implication. Assume that (p → q) is true. If p is false, then the implication (p → q) would be true regardless of the truth value of q. Therefore, the statement is always true.

(b) (p ∨ q) ∧ (¬p ∨ r) → (q ∨ r) = T

To prove this logical equivalence, we can use the law of implication and the law of conjunction. Assume that (p ∨ q) ∧ (¬p ∨ r) is true. If p is true, then the statement (p ∨ q) is true, and (q ∨ r) would also be true. If p is false, then the statement (¬p ∨ r) is true, and again, (q ∨ r) would be true. Therefore, the statement is always true.

(c) (p ∨ q) ∧ (¬q → r) ∧ ((¬q ∨ r) → q) = q

To prove this logical equivalence, we can use the law of implication and the law of conjunction. Assume that (p ∨ q) ∧ (¬q → r) ∧ ((¬q ∨ r) → q) is true. If q is true, then the statement (p ∨ q) is true, and since q is true, the whole statement is q. If q is false, then the statement (¬q → r) is true, and (¬q ∨ r) would be true, which implies that q is true. Therefore, the statement is always q. By applying logical reasoning and using the laws of logic, we have proven the given logical equivalences without resorting to truth tables.

The correct answer is: None of these answers is correct.The random variable representing the time lapsed during the run in this experiment is a continuous random variable.

I apologize for the previous incorrect answer. The random variable representing the time lapsed during the run in the given experiment is a continuous random variable. A continuous random variable can take on any value within a specified range or interval. In this case, the time elapsed during the run can theoretically be any non-negative real number, allowing for an infinite number of possible outcomes. It is not restricted to specific discrete values or intervals. Examples of continuous random variables include time, length, weight, and temperature.

Continuous random variables are characterized by their probability density function (PDF), which describes the likelihood of observing different values. In contrast, a discrete random variable would have a finite or countable set of possible values, such as the number of heads obtained in a series of coin flips.

The value of x in given figure is a whole number that is x = 6.6

When two tangent segment are drawn from an outside point to a circle, the sum of the dimensions of the first tangent segment and its exterior tangent segment equals the sum of the dimensions of the other secant segments and its exterior secant segment.

Given the image and the labelled measurement of two secant segments outside the predetermined circle that have a similar endpoint. We are required to determine what x's value is.

With these measurements, we can use the secant-secant theorem to solve for the value of x as we refer to and analyse the figure. We will therefore have this theorem applied.

(5) [(5) + ( x+4)] = (6) [6 + 7]

(5) [5+x+4] = (6) [13}

5 [9 + x] = 78

45 + 5x = 78

5x = 33

x = 6.6

Therefore the value of x is 6.6

Answer:

The answer is

C. The mapping represents y as a function of x, because each x-value corresponds to exactly one y-value.

Step-by-step explanation:

In mathematics, mapping is used synonymously to a function, and a function is basically a relation between two values or expressions say y and x

like the difference equation relating y and x.

In a function, for every value of x plugged into the function there is always a corresponding value of y.

Example.

Given the function

y=2x+5.

find the value of y when x=0

we are going to substitute x=0 and solve

y=2(0)+5

y=5

so for x=0 y=5

Three ratios that are equivalent to 18:21 are 6 : 7, 36 : 42 and 72 : 84

An equivalent ratio is a ratio that represents the same relationship between numbers as another ratio, but with different values.

You can create equivalent ratios by multiplying or dividing both parts of the ratio by the same non-zero number. For example, if a ratio is 4:8, an equivalent ratio would be 2:4.

Thus, 3 ratios that are equivalent to 18:21 can be:

18 : 21 = 6 : 7 (divide both sides by 3)

18 : 21 = 36 : 42 (multiply  both sides by 2)

18 : 21 = 72 : 84 (multiply  both sides by 4)

Answer:

The fact that shows that p+q+r=1 is at most 2/3 is well explained from what we have below.

Step-by-step explanation:

Given that:

The maximum of function P = 2pq+2pr+2rq is at most 2/3.

where ;

p+q+r=1

From  p+q+r=1

Let make r the subject ; then r = 1 - p - q

If we replace the value for r into the given function; we have:

P = 2pq+2pr+2rq

P = 2pq+2p(1 - p - q)+2(1 - p - q)q

P = 2pq + 2p - 2p² - 2pq + 2q -2pq -2q²

P = 2p - 2p² + 2q -2pq -2q²

By applying the standard method for determining critical points we obtain:

\(P_p\) = -4p - 2q + 2 = 0

\(P_q\) = -4q - 2p + 2 = 0

Divide all through by 2

\(P_p\) = -2p - q + 1 = 0

\(P_q\) = -2q - p + 1 = 0

\(P_p\) = -2p - q  = - 1

\(P_q\) = -2q - p  = - 1

Multiplying both sides by - ; we have:

\(P_p\) = 2p + q  =  1   ----- (1)

\(P_q\) = 2q + p  =  1    ------(2)

From equation (1) ; let make q the subject ; then

2p + q = 1

q = 1 - 2p

Now; let us replace the value of q = 1-2p into equation (2) , we have:

2q + p  =  1  

2(1-2p)+ p = 1

2 - 4p+p = 1

2 - 3p = 1

3p = 2-1

p = 1/3

Replacing the value of p = 1/3 into equation (1) ; we have :

2p + q  =  1  

2(1/3) + q = 1

2/3 + q = 1

q = 1 -2/3

q = 1/3

Taking the second derivative D; we have

\(D = P_{pp}P_{qq}-p^2_{pq}\)

D = -4 × -4 - (2²)

D = 16 - 4

D = 12

This implies that the given function has a minimum or maximum at its critical point for which  12 > 0

Therefore , the value for function p = q = r  since  p, q, and r are the proportions of A, B, and O in the  population.

Hence r = 1/3

P=2pq+2pr+2rq

P = 2(1/3)(1/3) + 2(1/3)(1/3) + 2(1/3)(1/3)

P = 6/9

P = 2/3

Answer:

x = 9

y = 5

Step-by-step explanation:

<N and < M are opposite equal sides. So they are equal as well. In addition, the base is equal to the other 2 sides. That means you are dealing with an equilateral triangle. All the angles are equal to 60 degrees.

7x - 3 = 60 degrees     Add 3 to both sides

      3      3

7x = 63                         Divide by 7

x = 63/7

x = 9

Just for the sake of completeness, we'll find y

11y + 5 = 60                 Subtract 5 from both sides

     -5      -5

11y = 55                       Divide by 11

y = 55 /11

y = 5

An object is moving along the x x -axis. At t t = 0 it is at x x = 0. Its x x -component of velocity vx v x as a function of time is given by vx(t)=αt−βt3 v x ( t ) = α t − β t 3 , where α= α = 7.2 m/s2 m / s 2 and β= β = 4.8 m/s4 m / s 4  the nonzero time at which x = 0 is 1.22 seconds.

To find the time at which the object is again at x=0, we need to solve the equation vx(t) = 0, which gives us:

αt - βt^3 = 0

t(α - βt^2) = 0

The solutions to this equation are t = 0 (which corresponds to the initial position) and t = ±√(α/β). Since we're looking for a nonzero time, we can discard the t = 0 solution and take t = √(α/β):

t = √(α/β) = √(7.2 m/s^2 / 4.8 m/s^4) = √(1.5 s^2) = 1.22 s

Therefore, the object is again at x=0 after a time of 1.22 seconds.

The complete arithmetic sequence is 1, .25, -0.5, -1.25, -2

The arithmetic sequence is given as:

1, .25, blank, -1.25, blank

Replace the blanks in the arithmetic sequence with x and y

So, we have:

1, .25, x, -1.25, y

An arithmetic sequence has a common difference (d)

The common difference is calculated using

d = T2 - T1

So, we have

d = 0.25 - 1

d = x - 0.25

d = y + 1.25

Substitute d = x - 0.25 in d = 0.25 - 1

x - 0.25 = 0.25 - 1

This gives

x = 0.25 + 0.25 - 1

Evaluate the sum

x = -0.5

Substitute d = 0.25 - 1 in d = y + 1.25

0.25 - 1  = y + 1.25

This gives

y = 0.25 - 1 - 1.25

Evaluate

y = -2

Hence, the complete arithmetic sequence is 1, .25, -0.5, -1.25, -2
