1. What operations would you use in order to solve 3x – 4 = 26. Please write the operations in the order you would use them.

What single percentage change is equivalent to a 14% increase followed by a 11%<br> decrease?

Vladimir79 [104]

Answer:

1.03 increase

Step-by-step explanation:

you just do 14 - 11 which equals 3

then because it's a positive answer, it means its a percentage increase and an increase is add on it 1.0 meaning its 1.03

With the aid of an illustrative example, discuss the relationship between the area of a region and the definite integral. *

melisa1 [442]

Answer:

The integral symbol in the previous definition should look familiar. We have seen similar notation in the chapter on Applications of Derivatives, where we used the indefinite integral symbol (without the a and b above and below) to represent an antiderivative. Although the notation for indefinite integrals may look similar to the notation for a definite integral, they are not the same. A definite integral is a number. An indefinite integral is a family of functions. Later in this chapter we examine how these concepts are related. However, close attention should always be paid to notation so we know whether we’re working with a definite integral or an indefinite integral.

Integral notation goes back to the late seventeenth century and is one of the contributions of Gottfried Wilhelm Leibniz, who is often considered to be the codiscoverer of calculus, along with Isaac Newton. The integration symbol ∫ is an elongated S, suggesting sigma or summation. On a definite integral, above and below the summation symbol are the boundaries of the interval, \left[a,b\right]. The numbers a and b are x-values and are called the limits of integration; specifically, a is the lower limit and b is the upper limit. To clarify, we are using the word limit in two different ways in the context of the definite integral. First, we talk about the limit of a sum as n\to \infty . Second, the boundaries of the region are called the limits of integration.

We call the function f(x) the integrand, and the dx indicates that f(x) is a function with respect to x, called the variable of integration. Note that, like the index in a sum, the variable of integration is a dummy variable, and has no impact on the computation of the integral.

his leads to the following theorem, which we state without proof.

300x + 20 + 5x + 10 -40x2 =

olganol [36]

Step-by-step explanation:

$305x + 30 - 80 \\ 305x - 50 \\ 305x = 50 \\ x = \frac{305}{50} \\ x = \frac{61}{10}$

Here is a scale diagram of part of a wall.

Rus_ich [418]

As Kamran has bought tiles for $60 while he needs only $50 tiles, therefore, he has bought enough tiles to cover the entire wall.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given the length of the wall on the diagram is 8 cm by 4 cm. And it is given that 4 cm is equal to 1 meters. Therefore, the original dimensions of the wall are,

8 cm → 8×(1/4) → 2 meters = 200 cms.

4 cm → 4×(1/4) → 1 meters = 100 cms

Now, the area of the wall in reality is 200 cm by 100 cm. Therefore, the total area of the wall is,

Total area = 200 cm × 100 cm = 20,000 cm²

The area of a single square tile of side length 10 cm is,

Area of a single tile = 10cm × 10cm = 100 cm²

The number of tiles that will be needed to cove the entire wall will be,

Number of tiles needed = 20000 / 100 = 200

Since the cost of a single tile is $0.25, therefore, the cost of 200 tiles will be,

Cost of 200 tiles = $0.25× 200 = $50

As Kamran has bought tiles for $60 while he needs only $50 tiles, therefore, he has bought enough tiles to cover the entire wall.
