Answer:

The sum of 78 and -78 is zero.

Step-by-step explanation:

I used a calculator ;)

The multiplier for the given economy is 4.

The multiplier represents the magnification effect of an initial change in autonomous spending on the overall output of an economy. It is calculated using the formula 1 / (1 - MPC), where MPC is the marginal propensity to consume.

In this case, the MPC is given as 0.75, which means that for every additional dollar of income, individuals spend 75 cents. The multiplier is calculated as 1 / (1 - 0.75) = 4.

The multiplier of 4 indicates that a change in autonomous spending, such as investment or consumption, will have a four times larger impact on the overall output of the economy. In other words, for every dollar increase in autonomous spending, the total output of the economy will increase by four dollars.

In this scenario, since the intended investment is $130, the total increase in output would be 4 * $130 = $520. Therefore, the multiplier effect amplifies the initial change in autonomous spending and leads to a larger increase in output in the economy.

The direct variation is y = 3/2 x, the value of y for x = 3 is 9/2.

A direct variation is defined as having variables that are directly proportional. When one variable's value rises, the other variable's value rises as well, and vice versa. Assuming k is constant, the following is how a direct variation is expressed:

y=kx

As y varies directly with x,

using direct variation,

y = kx

given, y = 3/4 when x = 1/2,

⇒ 3/4 = k 1/2

⇒ k = 3/2

when x = 3,

the value of y will be -

y = kx

⇒ y = 3/2. 3

⇒ y = 9/2

The numbers of ladies and gentlemen in the club are 2 and 18 respectively.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, there are 90% of ladies in the club, and the number of ladies is 12 more than 3 times the number of gentlemen.

Let the number of gentlemen is x and the number of ladies be y.

Since the number of ladies is 12 more than 3 times the number of gentlemen, it follows:

y  = 12 + 3x     (1)

Now, the total number of members in the club is:

x + y

Since there are 90% ladies in the club, it follows:

90%(x + y) = y

90(x + y)/100 = y

90x + 90y = 100y

90x = 100y - 90y

90x = 10y

9x = y             (2)

Now, substitute y = 9x into equation (1):

9x = 12 + 3x

9x -3x = 12

6x = 12

x = 2

Substitute x = 2 into equation (2):

9(2) = y

18 = y

Hence, the numbers of ladies and gentlemen in the club are 2 and 18 respectively.

Answer:

C(8) = $290

Step-by-step explanation:

Since Bob's Plumbing charge a flat fee of $50, then it is the y-intercept.

As detailed in the given problem, x is the number of hours they work.  

They charge $30 for every x number of hours on the job. This represents the slope.

C(x) represents the total cost of working for x number of hours.

Given these factors, we can establish the following function rule:

C(x) = 30x + 50

To evaluate the function for 8 hours of work:

C(8) = 30(8) + 50

C(8) = 240 + 50

C(8) = 290

Therefore, the cost of working for 8 hours is $290.

We are asked to find the derivative of the function f(x) = 2/x^5 - 5/x^3 using symbolic notation and fractions. the derivative of the function f(x) = 2/x^5 - 5/x^3 is f'(x) = -10/x^6 + 15/x^4.

To find the derivative of the function, we can apply the power rule and the constant multiple rule of differentiation.

Using the power rule, the derivative of x^n (where n is a constant) is given by nx^(n-1). Applying this rule to each term of the function, we get:

f'(x) = 2 * (-5)x^(-5-1) - 5 * (-3)x^(-3-1)

     = -10x^(-6) + 15x^(-4)

Simplifying further, we can rewrite the derivative as:

f'(x) = -10/x^6 + 15/x^4

Thus, the derivative of the function f(x) = 2/x^5 - 5/x^3 is f'(x) = -10/x^6 + 15/x^4.

[(h + 10) - 4] × (h - 4) = 1344. This equation to find the height and length of the unframed portrait, and then calculate the area.

Let's denote the height of the portrait as 'h' inches. According to the problem, the length of the portrait is 10 inches longer than its height, so the length would be 'h + 10' inches.

Now, we need to find the dimensions and area of the unframed portrait. To do this, we need to subtract the thickness of the frame from the dimensions of the framed portrait.

Dimensions of the framed portrait:

Length: (h + 10) inches

Height: h inches

Dimensions of the unframed portrait:

Length: (h + 10) - (2 + 2) inches (subtracting the thickness of the frame)

Height: h - (2 + 2) inches

Area of the unframed portrait:

Area = Length × Height

Area = [(h + 10) - 4] × (h - 4) square inches

We are given that the total area of the framed portrait is 1344 square inches. So, we can set up the equation:

[(h + 10) - 4] × (h - 4) = 1344

Solve this equation to find the height and length of the unframed portrait, and then calculate the area.

The expression x to the power of 3 times x to the power of 3 times x to the power of 3 is not equivalent to an expression x to the power of 3 times 3 times 3.

For given question,

We have been given a statement 'x to the power of 3 times x to the power of 3 times x to the power of 3 '

We can write above statement in expression form as,

x³ × x³ × x³

Now, we simplify above expression.

We know that the product rule of exponents states that, 'To multiply expressions with the same base, add the exponents while keeping the base the same.'

So, x³ × x³ × x³ = \(x^{3+3+3}\)

⇒  x³ × x³ × x³ = \(x^{9}\)                    ....................................(1)

Also, we have been given a statement that 'x to the power of 3 times 3 times 3'

We can write above statement in expression form as,

\(x^{3\times 3\times 3}\)

Now we simplify above expression.

By power of a product rule of exponents,

\(x^{3\times 3\times 3}=x^{27}\)                           .....................................(2)

From (1) and (2),

x³ × x³ × x³ ≠ \(x^{3\times 3\times 3}\)

Therefore, the expression x to the power of 3 times x to the power of 3 times x to the power of 3 is not equivalent to an expression x to the power of 3 times 3 times 3.

If the court determined that the railroad employee was negligent towards the man with the package, it would not automatically make the railroad liable for the injury to Palsgraph; liability would depend on establishing a duty of care, breach, causation, and damages specific to Palsgraph's situation

In negligence cases, to establish liability, the plaintiff must prove that the defendant owed them a duty of care, that the defendant breached that duty, and that the breach directly caused the plaintiff's injuries or damages. Additionally, the plaintiff must show that they suffered actual harm or damages as a result of the defendant's actions.

In Palsgraph g. Long Island Railroad Co., the court decided that the railroad employee's conduct was not negligent towards Ms. Palsgraph, and therefore the railroad was not liable for her injury. However, if the court had determined that the railroad employee was negligent towards the man with the package, it would only establish negligence towards him and not automatically make the railroad liable for Palsgraph's injury. Palsgraph would still need to establish that the railroad owed her a duty of care, that the duty was breached, and that the breach caused her specific harm or damages. The focus would be on establishing a duty of care and causation specific to Palsgraph's situation, separate from the negligence towards the man with the package.

By using trigonometric relations, we will see that:

a = 7/2, b = (7*√3)/2

So the correct option is the second option, counting from the top.

Here we have a right triangle where we only know the value of the hypotenuse and one of the angles, and we want to find the measures of both of the legs (also known as cathetus).

Then we will use the two relations:

cos(θ) = (adjacent cathetus to the angle)/(hypotenuse)

With that relation we can find the value of b:

cos(30°) = b/7

cos(30°)*7 = b = (7*√3)/2

The other relation we will use is:

sin(θ) = (opposite angle to the given angle)/(hypotenuse)

With that we can get the value of a:

sin(30°) = a/7

sin(30°)*7 = a = 7/2

Then the correct option is:

a = 7/2, b = (7*√3)/2

Which is the second option, counting from the top.
