Need help with delta math

Answer:

First you would make 62% into \(\frac{62}{100}\)

\(7893+82-\)\(\frac{62}{100}\)

Than you would do 7893+82 which is 7975

\(7975-\frac{62}{100}\)

You would than simplify \(\frac{62}{100}\) which is \(\frac{31}{50}\)

\(7975- \frac{31}{50}\)

Therefore your answer will be \(\frac{398719}{50}\) or in decimal form it will be \(7974.38\)

The system of equations that matches the given graph is:

A. 3x - 6y = 12

9x - 18y = 36

To determine which system of equations matches a given graph, we need to analyze the slope and intercepts of the lines in the graph.

Looking at the options provided:

A. 3x - 6y = 12

9x - 18y = 36

B. 3x + 6y = 12

9x + 18y = 36

Let's analyze the equations in each option:

For option A:

The first equation, 3x - 6y = 12, can be rearranged to slope-intercept form: y = (1/2)x - 2.

The second equation, 9x - 18y = 36, can be simplified to 3x - 6y = 12, which is the same as the first equation.

In option A, both equations represent the same line, as they are equivalent. Therefore, option A does not match the given graph.

For option B:

The first equation, 3x + 6y = 12, can be rearranged to slope-intercept form: y = (-1/2)x + 2.

The second equation, 9x + 18y = 36, can be simplified to 3x + 6y = 12, which is the same as the first equation.

In option B, both equations also represent the same line, as they are equivalent. Therefore, option B does not match the given graph.

Answer:

(8,0)

Step-by-step explanation:

Our given expression is \(f(x) = x^{2} - 16x + 64\)

The x-intercept is x when y = 0, so simply rewrite the expression as \(0 = x^{2} - 16x + 64\) and solve for x.

x = 8, which means that your x-intercept is (8,0).

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The chances that an event will occur increases with its probability.

Total number of integer from 100 to 999 where both are included = 900

Now, from 100- 999 inclusive there are 19 numbers containing at least zero

(100,101,102,103,104,105,106,107,108,109,110,120,130,140,150,160,170,180,

190)

and we have the same number in each hundred from x00 to x99 where x ranges from 1 to 9

so, the total number of integer from 100 - 999 inclusive that have zero = 9 (19) = 171

Hence, the probability that  we select a digit that contain zero

= 171/900

= 19/100

=0.19%

The probability that it contains no 0's randomly is 0.19%

Answer:  B. a + (-b) = 7

Step-by-step explanation:

The answer is B. a + (-b) = 7. a + (-b) is the same thing with a - b.

A. a + b = -7

a - b = 7 means the differences of a and b is 7, choice A is talking about their sum, so it could not be true.

C. -a - b = 7

if you multiply -1 on both sides, you will get a + b = -7. Therefore, it will not be true.

D. b - a = 7

a - b = 7 means that a is 7 more than b. The choice d shows the opposite, which it states that b is 7 more than a. Therefore, it is not true.

The person would save $404 by choosing the HMO for physical therapy sessions.

Total cost refers to the overall expense incurred by a business or an individual to produce or acquire a product or service.

Let's first calculate the total cost of physical therapy sessions without insurance:

Total cost = 12 sessions * $145 per session = $1740

With the insurance policy, the person has to pay a deductible of $580 first. After that, the insurance will cover 80% of the remaining cost. So, the person pays:

($1740 - $580) * 0.2 = $232

Therefore, with the insurance policy, the person pays $580 + $232 = $812 for 12 physical therapy sessions.

If the person opts for the HMO instead, the cost would be $34 per session, so:

Total cost = 12 sessions * $34 per session = $408

Therefore, the person would save:

$812 (with insurance) - $408 (with HMO) = $404

So, the person would save $404 by choosing the HMO for physical therapy sessions.

The volume of the solid formed when the region R bounded by y=2x and y=x^2 is revolved about the x-axis is 64π/15. This can be found using the washer method, where the washer is formed by subtracting the area of a smaller cylinder from the area of a larger cylinder.

The radius of the smaller cylinder is given by y=x^2 and the radius of the larger cylinder is given by y=2x. The thickness of the washer is dx. Here is the explanation in more detail:

The washer method is a method for finding the volume of a solid of revolution that is created by rotating a region bounded by two curves about a line. The region R is bounded by the curves y=2x and y=x^2. The x-axis is the line of rotation. The washer is formed by subtracting the area of a smaller cylinder from the area of a larger cylinder. The radius of the smaller cylinder is given by y=x^2 and the radius of the larger cylinder is given by y=2x. The thickness of the washer is dx.

The volume of the washer is given by the following formula:

V = π[(r_1)^2 - (r_2)^2] * dx

where r_1 is the radius of the smaller cylinder, r_2 is the radius of the larger cylinder, and dx is the thickness of the washer. Plugging in the values of r_1 and r_2, we get the following formula for the volume of the solid of revolution:

V = π[(x^2)^2 - (2x)^2] * dx

Simplifying the expression, we get the following formula:

V = π(x^4 - 4x^2) * dx

Now, we need to integrate this expression with respect to x. The limits of integration are from x=0 to x=1.

V = π∫_0^1 (x^4 - 4x^2) * dx

Evaluating the integral, we get the following answer:

V = 64π/15

Therefore, the volume of the solid of revolution is 64π/15.

What is triangle proportion?

According to the Triangle proportion rule, When a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.

In the diagram;

The side with x is a reflexive side of both triangles and as such from triangle proportionality theorem we can say that;

⇒6/x = 3/6

⇒ 36 = 3x

⇒ x = 12

The MP curve initially rises to its maximum value because of the specialized nature of the fixed capital, where each additional worker's productivity rises due to the marginal product of the fixed capital.

Production Function: q = f(L,K) = 20L + 25K + 5KL - 0.03L² - 0.02K²

Given, K = 5, i.e., capital is fixed. Therefore, the total product of labor, average product of labor, and marginal product of labor are:

TPL = f(L, K = 5) = 20L + 25 × 5 + 5L × 5 - 0.03L² - 0.02(5)²

= 20L + 125 + 25L - 0.03L² - 5

= -0.03L² + 45L + 120

APL = TPL / L, or APL = 20 + 125/L + 5K - 0.03L - 0.02K² / L

= 20 + 25 + 5 × 5 - 0.03L - 0.02(5)² / L

= 50 - 0.03L - 0.5 / L

= 49.5 - 0.03L / L

MP = ∂TPL / ∂L

= 20 + 25 - 0.06L - 0.02K²

= 45 - 0.06L

The following diagram illustrates the TP, MP, and AP curves:

Figure: Total Product (TP), Marginal Product (MP), and Average Product (AP) curves

The production function demonstrates increasing marginal returns due to specialization when L is low enough, i.e., when L ≤ 750. The marginal product curve initially increases and reaches a maximum value of 45 units of output when L = 416.67 units. When L > 416.67, MP decreases, and when L = 750 units, MP becomes zero.

The MP curve's initial increase demonstrates that the production function displays increasing marginal returns due to specialization when L is low enough. This is because when the capital is fixed, an additional unit of labor will benefit from the fixed capital and will increase production more than the previous one.

In other words, Because of the specialised nature of the fixed capital, the MP curve first climbs to its maximum value, where each additional worker's productivity rises due to the marginal product of the fixed capital.

The APL curve initially rises due to the MP curve's increase and then decreases when MP falls because of the diminishing marginal returns.
