Which of the following definite integrals could be used to calculate the total area bounded by the graph of y = x^3 – 3x^2 + 2x
castortr0y [4]

Answer: The correct option is second, i.e. ,"2 times the integral from 0 to 1 of the quantity x cubed minus 3 times x squared plus 2 times x, dx".

Explanation:

The given equation is,

y=x^3-3x^2+2x

It can be written as,

f(x)=x^3-3x^2+2x

Find the zeros of the equation. Equation the function equal to 0.

0=x^3-3x^2+2x

x(x^2-3x+2)=0

x(x^2-2x-x+2)=0

x(x-2)(x-1)=0

So, the three zeros are 0, 1 and 2.

The graph of the equation is shown below.

From the given graph it is noticed that the enclosed by the curve and x- axis is lies between 0 to 2, but the area from 0 to 1 lies above the x-axis and area from 1 to 2 lies below the x-axis. So the function will be negative from 1 to 2.

The area enclosed by curve and x-axis is,

A=\int_{0}^{1}f(x)dx+\int_{1}^{2}[-f(x)]dx

A=\int_{0}^{1}f(x)dx-\int_{1}^{2}f(x)dx

From the graph it is noticed that the area from 0 to 1 is symmetric or same as area from 1 to 2. So the total area is the twice of area from 0 to 1.

A=2\int_{0}^{1}f(x)dx

A=2\int_{0}^{1}[x^3-3x^2+2x]dx

Therefore, The correct option is "2 times the integral from 0 to 1 of the quantity x cubed minus 3 times x squared plus 2 times x, dx".

PLEASE HELP !!!What is the distance between the tick marks on the number line? A number line going from 0 to 2 in increments of
jek_recluse [69]

Answer:

1/5 or A

Step-by-step explanation:

Hello. Please excuse the idiot above we do not know how he formed or why he speaks like a gorilla on crack. Anyways, we, humans, believe that 1/5 is the correct answer since their are 5 intervals between 0 and 1 between one of the tick marks is 1/5 since there are 5 intervals. I really hope you guys are human not this gorilla above us. I hope I made your day please rate 5 stars , add thanks and please mark brainliest. :)

Mary has some boxes that are all cubes of the same size she uses 5 of the boxes to make a tower with a height of 115 cm she puts
liberstina [14]

Answer:

161 centimeters

Step-by-step explanation:

To find the total height, we need to find the wait of each individual box. Since we have five boxes stacked up on each other with a height of 115, we can divide 115 by 5 to get 23. Now that we know that each box is 23 centimeters tall, we can multiply that by 2 because 2 more boxes were added, and then add that to 115.

115/5=23

23*2=46

46+115=161

Hope this helps!
