The first law is called the Law of Detachment. The law states that if p → q and p is true, then q is true.

The second law is the Law of Syllogism. It states that If p → r and q → r, then p → r is true.

It is to be noted that the Law of Detachment is the most often employed deductive reasoning theory.

In other words, if a conditional statement and its hypothesis are true, the conclusion is likewise true. In other words, the conclusion may be "separated" from the conditional.

In the above instance, p is synonymous with having a cat; while q is synonymous with it chasing a rat.

Shelley's cup of tea is cooling down at the rate of 1.2 degree per minute.

According to the question,

We have the following information:

Shelley's cup cooled down 12 degrees in 10 minutes.

In order to find the rate of cooling down of the cup of tea, we will divide the degrees of the cooling by the total number of minutes.

So, we have the following expression:

Rate of cooling down of Shelley's cup = Total degrees the cup cooled down/total time taken

Rate of cooling down of Shelley's cup = 12/10

Rate of cooling down of Shelley's cup = 1.2 degree per minute

Hence, the rate of cooling down of Shelley's cup is 1.2 degree per minute.

Based on the calculation below, the amount of cash that the Smith and Jones manufacturing company kept in the bank was $500,000.

Let x represents the amount of cash that Smith and Jones manufacturing company has.

Therefore, we have:

Interest amount from bank = Cash * A third * Bank interest rate = x * (1/3) * 0.5% = x0.0017

Interest amount from long-term investments = Cash * Two-third * Long-term investments interest rate = x * (2/3) * 3.5% = x0.023

Total interest earned = Interest amount from bank + Interest amount from long-term investments = $37,500 ...................... (1)

Substituting all the relevant values into equation (1) and solve for x, we have:

x0.0017 + x0.023 = $37,500

x0.025 = $37,500

x = $37,500 / 0.025

x = $1,500,000

Amount kept in the bank = Cash * A third = $1,500,000 * (1 / 3) = $500,000

The absolute value equation is |x - 70| = 0.02, while the minimum and maximum torque are 69.98 and 70.02 foot pounds

From the question, the given parameters are:

Specification = 70 foot pounds

Margin of error = 0.02 foot pounds

The absolute value equation of the scenario is then calculated as

|x - Specification| = Margin of error

Substitute the known values in the above equation

So, we have

|x - 70| = 0.02

Solving the equation, we have

x - 70 = 0.02 and x - 70 = -0.02

Add 70 to all sides

x = 70.02 and x = 69.98

Hence, the range is 69.98 to 70.02

Given is the

quadratic function

, which has a graph of parabola.

It has two

x-intercepts

, with the greater one representing the

projectile on the ground, at h(t) = 0

.

Let's

solve

the equation:

- 16t² + 32t + 128 = 0

t² - 2t - 8 = 0

t² - 2t + 1 - 9 = 0

(t - 1)² = 9

t - 1 = 3 and t - 1 = - 3

t = 4

and t = - 2

The root with the greater value is

t = 4

, which represents the time we need.

[tex]\qquad \tt \rightarrow \:4 \:\: sec [/tex]

____________________________________

height of an object projected in air with time is represented by the given equation :

[tex]\qquad\displaystyle \tt \rightarrow \: h(t) = - 16 {t}^{2} + 32t + 128[/tex]

The height when the object hits the ground will be 0

so, just equate the equation with 0, and we will get the value of t (time) when the projectile will be back to ground.

[tex]\qquad\displaystyle \tt \rightarrow \: - 16 {t}^{2} + 32t + 128 = 0[/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: - 16( {t {}^{2} - 2t}^{} - 8) = 0[/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: t {}^{2} - 2t - 8 = 0[/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: t {}^{2} - 4t +2 t - 8 = 0[/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: t(t - 4) + 2(t - 4) = 0[/tex]

[tex]\qquad\displaystyle \tt \rightarrow \: (t - 4)(t + 2) = 0[/tex]

So,

[tex]\qquad\displaystyle \tt \rightarrow \: t = 4 \: \: \: \: or \: \: \: \: t = - 2[/tex]

but since time can't be negative, t = 4 seconds

The object will be back on ground after 4 seconds.

By taking a product, we can see that the total energy consumed by the console is 42,504 watt-hours.

Here we know that the console uses 154 watt-hours of energy each hour.

So, if you use it for x hours, the energy consumed is given by the product:

E = ( 154 watt-hours)*x

In this case, we know that the console is used for 276 hours, then we can write:

E = (154 watt-hours)*276 = 42,504 watt-hours.

What is Weight ?

The force exerted on an object by gravity is known as its weight. The gravitational force acting on the item is referred to as weight in several common textbooks. Some people refer to weight as a scalar quantity that measures the gravitational force's strength.

Given,

The weight of one newborn kitten = 1/4 pounds
The value of pound in kilograms = 1pound = 0.45kg
convert the weight from  pound to kilograms = 1/4 x 0.45

                                                                              = 0.1125kg

Now, to find out total weight of litter of 6 kitten in kilograms

The answer should be dragged and dropped into the box to match each point to its coordinates as follows;

Point A ⇔  (2 1/4 , 1 1/2).

Point B ⇔  (-1 1/4 , 1 1/2).

Point C ⇔ (-2 1/2 , 1/4).

In Mathematics, an ordered pair is sometimes referred to as a coordinate and it can be defined as a pair of two (2) elements or data points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate (abscissa) and the y-coordinate (ordinate) on the coordinate plane of any graph.

In Mathematics and Geometry, a quadrant simply refers to the area that is occupied by the values on the x-coordinate (x-axis) and y-coordinate (y-axis) of a cartesian coordinate.

Based on the cartesian coordinate (grid) below, the coordinates points and quadrants should be identified as follows;

Point A ⇔  (2 1/4 , 1 1/2) → quadrant 1.

Point B ⇔  (-1 1/4 , 1 1/2) → quadrant 2.

Point C ⇔ (-2 1/2 , 1/4) → quadrant 2.

Answer:

• score with two questions wrong = 18

• score with x questions wrong = (20 - x)

Step-by-step explanation:

The question is divided into two parts.

The first part asks us to calculate the marks that would be scored out of 20 if someone got 2 questions wrong. To do this we simply have to subtract 2 from 20 to get the score:

score = 20 - 2

         = 18

Therefore, Yasmin's score would be 18.

The second part asks us to calculate the marks that would be scored if someone got x questions wrong instead. As we did in the first part, we have to take away x from 20 in order to get the score:

score = 20 - x,

where x can be any whole number.

Therefore, Yasmin's score would be (20-x).

Answer:

  176 yd²

Step-by-step explanation:

You want the shaded area of a parallelogram that has a trapezoid-shaped white area.

The area of a parallelogram is given by the formula ...

  A = bh

The parallelogram shown has a base of 17 yd and a height of 7 yd +6 yd. Its area is ...

  A = (17 yd)(7 yd +6 yd) = 221 yd²

The area of the white space cut from the parallelogram is given by the formula ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the parallel bases of the trapezoid, and h is the distance between them.

  A = 1/2(7 yd +8 yd)(6 yd) = 45 yd²

The shaded area is the difference of these two areas:

  shaded area = 221 yd² -45 yd² = 176 yd²

The area of the shaded region of the parallelogram is 176 yd².

The amount of cash that as kept in the bank is $937500.

Let's have x represent the amount of cash.

One portion of it pays 0.5%, so 0.005x; the other portion pays 3.5%, so 0.035x. This gives us:

0.005x + 0.035x = 37500

Combining like terms:

0.040x = 37500

Solve for x:

x = (37500)/(0.04)

x = 937500

Therefore, the company started with $937,500.

The inequality is incorrect because testing the point (5, 100) simplifies to the inequality 100 ≥ 150.

An inequality can be defined as a mathematical relation that is typically used for comparing two (2) or more numerical data and variables in an equation based on any of the following arguments (symbols):

Next, we would evaluate and simplify the given inequality in order to determine its solution as follows:

y ≥ –2(x – 10)² + 200.

At point (5, 100), we have:

100 ≥ –2(5 – 10)² + 200.

100 ≥ –2(-5)² + 200.

100 ≥ –2(25) + 200.
