Use limits to find the area of the region bounded by the graph f(x)=4-2x^3 , the x-axis , and the vertical lines x=0 and x=1
gtnhenbr [62]

Answer:

\frac{7}{2} square units.

Step-by-step explanation:

We have to use limits to find the area of the region bounded by the graph f(x) = 4 - 2x^{3} , the x-axis, and the vertical lines x=0 and x=1.

So, the area will be

A = \int\limits^1_0 {(4 - 2x^{3})} \, dx

= [4x - \frac{x^{4}}{2} ]^{1} _{0}

= 4 - \frac{1}{2}

= \frac{7}{2} square units. (Answer)

The orgin of the coordinate plane is the point at (0,0). Why is the orgin an important point?
stiks02 [169]

<u>Importance of origin:</u>

The point at which the two axes intersect is called the origin. The intersecting x- and y-axes divide the coordinate plane into four sections.

The origin is at 0 on the x-axis and 0 on the y-axis. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

The origin is used to determine the coordinates for every other point on the graph. It is generally the starting point on a grid.

In general, origin is the place where something comes from or the place where something originates.

Can someone please help me (6th grade math) please and thank you!
Assoli18 [71]

Answer and Step-by-step explanation:

First, you create an expression that equals the perimeter of the shape.

5r + 2s + 3r + 2s + 5r + 2s + 3r + 2s

<u>Simplify</u>

16r + 8s

Now we look at the students' expressions.

I can see that Brain's expression is equivalent to perimeter of the shape. Do you know why?

It is because his answer is the un-distributive version of our answer.

He simply took out the common number that is in 16 and 8, which 8.

<u>So, Brian is correct.</u>
