Answer:

[(2/3)(9a)] + [(2/3)(6)] = 27.4

a = 3.9

Step-by-step explanation:

Let's start with the first portion of the equation: (2/3) * (9a)

Rewrite (2/3) * (9a) as => (2/3) * (9a/1); multiplying the numerator with the numerator, as well as the denominator with denominator, you should get (18/3a) => 6a

Onto the second part of the equation.... quite simple: (2/3)(6) = 12/3 = 4

Putting it all together, the entire equation is equal to 27.4

Finding the value of a: the new equation is 6a + 4 = 27.4

Subtract 4 from the total value of 27.4, and you should get 23.4

After this, your equation should be 6a = 23.4

Now, to finally find the value of (a), divide 23.4 by 6

This should leave you with a = 3.9

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.
