Using the De Morgan's Law, the equivalent logical expression of the statement ∼p ∨ ∼q is ∼(p ∧ q)

The expression is given as

∼p ∨ ∼q

The above expression is a logical expression

The De Morgan's Law of logical expression states that

∼x ∨ ∼y = ∼(x ∧ y)

Next, we replace the variables x and y with the given variables in the question

So, we have

∼p ∨ ∼q = ∼(p ∧ q)

-x² + 3x +3 is the domain of all real numbers.

Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, subtraction, multiplication, and division.

Let the two functions be f and g then f(x) = 3x - 2 and g(x) = x² + 1.

we have to calculate (f - g)(x)

Which is equivalent to:

(f - g)(x) = f(x) - g(x)

Taking the two functions and substituting them into this expression, we get,

f(x) - g(x) = (3x - 2) - (x² + 1)

simplifying the above function, we get

f(x) - g(x) = 3x - 2 - x² - 1

(f - g)(x) = -x² + 3x - 2 - 1

Therefore, (f - g)(x) = -x² + 3x +3

We must also determine the domain of the new function. However, because this is a second-order function with no denominators, logarithms, or roots, there are no restrictions on the value of x; thus, the domain is all real numbers.

The measurement of angle A and B is 44° and 46° respectively.

What are complementary angles ?

When the sum of two angle is 90 degree it is known as complementary angles and when a line divides the line than the sum of angles formed with the given straight line is always equals to 90 degree.

It is given that the angle A and B are complementary angles whose measurements are :

∠A = (6x + 2)°

and , ∠B = (4x + 18)°

The sum of angle A and B will be 90 degree as they are complementary angles that is :

∠A + ∠B = 90°

Now, solving by adding like terms and finding the value of x :

6x +2 + 4x + 18 = 90°

10x + 20 = 90°

10x = 90-20

10x = 70°

x = 7°

now, the measurement of angle A will be :

∠A = (6x + 2)°

∠A = (6 · 7 + 2)°

∠A = (42 + 2)°

∠A = 44°  and  ∠B = 46°

Therefore, the measurement of angle A and B is 44° and 46° respectively.

the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

We are given the two equations:

y = - x - 4

- 7 x + 8 y = 16

We need to solve these equations by substitution.

We will substitute the equation 1 in the equation 2 to get the values of x and y:

- 7 x + 8 y = 16

- 7 x + 8 (- x - 4) = 16

- 7 x - 8 x - 32 = 16

- 15 x = 16 + 32

- 15 x = 48

Divide both sides by - 15, we get that:

x = 48 / - 15

x = - 16 / 5

y = - x - 4

Put the value of x

y = 16 / 5 - 4

y = 16 - 20  / 5

Subtract to get the value:

y = - 4 / 5

Therefore, we get that, the equations y = - x - 4 and - 7 x + 8 y = 16 have the solution as x = - 16 / 5 and y = - 4 / 5.

If the allocation doubles every week, that represents exponential growth.

Given there are many types of growth models, and models that grow at a constant rate are linear and models that grow exponentially at an increasing rate.

Linear growth is characterized by growth by the same amount per unit  time.

Exponential growth is a process of increasing numbers over time. This happens when the instantaneous rate of  change of a quantity over time is proportional to the quantity itself.

Exponential growth because the first week you may only get a dollar, but  the next week you get 2, then 4, and so on. Your allowance doesn't grow by the same amount every week, so the number it doubles is exponential.

Therefore, if the allowance doubles every week, it represents a exponential growth multiplier because samples growing at a constant rate are linear.

For Systolic (x)

mean= sum(x)/10 = 1278/10 = 127.8

stdev= s =sqrt( (sum(x^2 - 10*127.8^2)/9) = sqrt ( (166402 - 10*127.8^2)/9) =18.48

So coefficient of variation ( systolic)  is = (stdev/mean )*100 = (18.48/127.8)*100 = 14.5 %

For Diastolic (x)

mean= sum(y)/10 = 731/10 = 73.1

stdev= s =sqrt( [tex](sum(x^2 - 10*73.1^2)/9) = sqrt ( (54771 - 10*73.1^2)/9)[/tex]= 12.18

With an inverse relationship, when the pressure is increased to 400 kPa, the volume will be 0.5L, assuming that the temperature and number of particles are constant.

Boyle's Law states the inverse relationship between volume and pressure. It states that a constant amount of gas at a constant temperature, decreasing the volume will increase its pressure, and increasing its volume will decrease its pressure.

V = k/P or P1V1 = P2V2

where V = volume

P = pressure

If a gas has a volume of 1 L at a pressure of 200 kPa, and assuming that the temperature and number of particles are constant, using the inverse relationship, solve for the volume of the gas at a pressure of 400 kPa.

P1V1 = P2V2

200 kPa(1L) = 400 kPa(V2)

V2 = 200/400

Answer:

The maximum height that the rocket will reach is 271 feet.

Step-by-step explanation:

We first calculate the time, t it takes the rocket to reach maximum height from v = u - gt. Since u = initial velocity = 128 ft/s, v = velocity at maximum height = 0  ft/s and g = acceleration due to gravity = 32 ft/s².

So, v = u - gt.

t = (u - v)/g

= (128 ft/s - 0 ft/s)/32 ft/s²

= 128 ft/s ÷ 32 ft/s²

= 4 s.

We calculate the maximum height from

y - y₀ = ut - 1/2gt² where y₀ = 15 ft and all other variables are as above.

Substituting these values into the equation, we have

y - y₀ = (u - 1/2gt)t

y - 15 ft = (128 ft/s - 1/2 × 32 ft/s² × 4 s) × 4 s

y - 15 ft = (128 ft/s - 64 ft/s)4 s

y - 15 ft = 64 ft/s × 4 s

y - 15 ft = 256 ft

y = 256 ft + 15 ft

y = 271 ft

So, the maximum height that the rocket will reach is 271 feet.

What are zeros ?

zeros denotes the factors of the given equation in other words the zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.

Polynomial roots are the same as polynomial zeros, so they can be found by factoring the quadratic equation into two linear factors, after which they can be equating to zero.

Now, considering the given Quadratic Equation to find x :

2x² - x - 120 = 0

writing the above equation into two linear factors as :

2x² - 16x + 15x - 120 = 0

2x(x-8) + 15(x-8) = 0

(x-8)(2x+15) = 0

Now, equating each linear equation to zero to find the factors:

(x-8) = 0 and (2x+15) = 0

x = 8 and x = -15/2.
