find the x intercepts of f(x)=x^4+x^3-4x^2-4x

The correct approaches that can be used to solve the increase in area are

The area of the circle has an estimated increment of 527.52 square mm

The area of a shape is the amount of space on the shape

For all regular quadrilaterals, you multiply the side lengths to determine the area

From the question, the given parameters are:

Previous radius = 42

New radius = 44

Calculate the change in the radius

dr = New radius - Previous radius

Substitute the known values in the above equation

So, we have

dr = 44 - 42

Evaluate

dr = 2

The above method leads to a differentiation problem where dr = 2

So, the correct approaches to the problem include

The area of a circle is

A = πr²

Differentiate

d(A) = 2πr * dr

Where

r = 42

dr = 2

So, we have

d(A) = 2 * 3.14 * 42 * 2

Evaluate

d(A) = 527.52

Hence, the estimated increase in the area is 527.52 square mm

The third option is the answer!!!

The quotient of 550six and 50six​ is obtained by the calculation to be   11 six

We know that the result that we obtain after we have carried out a division operation is called a quotient. In this case, we have been required to carry out the operation of division in base six.

We could start by converting the both values to base 10 as follows;

(5 * 6^2) + (5 * 6^1) + (0 * 6^0) = 180 + 30 + 0 = 210 ten

(5 * 6^1) + (0 * 6^0) = 30 + 0 = 30 ten

Then we carry out the division in base ten; 210 ten/30 ten = 7 ten

We convert back to base six to obtain 11 six

There are many other types of reactions in chemistry, but the exothermic reaction and the endothermic reaction are the two most common forms.

Respiratory reaction is an example of an exothermic reaction, which is one in which energy is released in the form of heat. Exothermic reactions transfer energy from the system to the environment, raising the ambient temperature.

An endothermic reaction is one in which energy is removed from the system during the process. An example of an endothermic reaction is photosynthesis, in which plants use solar energy to produce food.

To understand what a triangle is, we need to understand some basic concepts of the Euclidean geometry. There are three undefined terms, that is, fundamental elements that cannot be defined but are described in terms of its attributes. Those terms are point, line and plane.

The equation D show the multiplication property of inequality if n+4 =11

What is inequality ?

inequality, When two numbers or algebraic expressions are stated to be greater than, greater than or equal to, less than, or less than or equal to each other in order. Inequalities can be stated as either statements of fact in the form of theorems, which are solved using methods similar to those used to solve equations, or as questions. For instance, the triangle inequality states that the length of the remaining side is greater than or equal to the sum of the lengths of any two sides of a triangle. Many of these inequalities, including the Cauchy-Schwarz inequality, are used in the proofs of many of mathematical analysis' most significant theorems.

This equation passes through (0,2) and (4,0).

Now we can plot the points and join them to get the corresponding lines on the graph as,

It is observed that the two lines intersect at point (2,1).

So the solution to the given equations must be x=2 and y=1.

The answer is

(a) the fixed cost when zero items are produced is $500 .

(b) cost for making 25 items is $750  .

(c) the domain and range of cost function is [0,100] and [500,1500] respectively  .

It the question ,

it is given that

the cost function is C(x)=10x+500  

Part(a)

to determine the fixed cost when 0 items are produced

Since 0 items are produced , we substitute the value x=0 in the cost function , we get

C(0)=10(0)+500

= 500

the fixed cost is $500.

Part(b)

to find the cost of making 25 items , we substitute x=25

On substituting the x=25 , we get

C(25)=10(25)+500

= 250+500

=750

the cost for 25 items is $750.

Part(c)

to find the domain of the cost function C(x)

Given that the maximum cost allowed is 1500

So, 1500=10x+500

10x=1500-500

10x=1000

x=100

So minimum 0 items and maximum 100 items can be produced ,

hence the Domain is [0,100]

to find the range

substituting x=0, the cost = $500

on substituting x=100 , the cost = $1500

the Range is [500,1500]

Therefore , (a) the fixed cost when zero items are produced is $500 .

(b) cost for making 25 items is $750  .

(c) the domain and range of cost function is [0,100] and [500,1500] respectively  .

Without the actual data for the average prices of gold in 2010 and 1970, I cannot provide the exact quotient. However, if we assume that we have the data, we can calculate the quotient by dividing the average price of gold in 2010 by the average price of gold in 1970. The resulting quotient would indicate how many times more expensive gold was in 2010 compared to 1970.

For example, if the average price of gold in 2010 was $1,500 per ounce and the average price in 1970 was $35 per ounce, then the quotient would be:

$1,500 / $35 = 42.86

This means that the average price of gold in 2010 was 42.86 times more expensive than the average price in 1970.

It is important to note that the actual quotient will depend on the actual data for the average prices of gold in 2010 and 1970.
