Answer:

0.075 sq km

Step-by-step explanation:

Given that there is a rectangular field with dimensions of length =300 m and width = 250 m.

We have to calculate area of this rectangle in the units of square kilometres.

Let us convert length and width into km

1000m = 1 km

Hence length = 300/1000= 0.3 km and

width = 250/1000 = 0.25 km.

ARea = length x width = 0.3 x 0.25

=0.075 square km.

1.Disc method.
In this method the volume is given by:

\boxed{V=\pi\int\limits_a^b\big[f(x)\big]^2}

so:

V=\pi\int\limits_1^3x^4\,dx=\boxed{\pi\int\limits_1^3\big[x^2\big]^2\,dx}

A) Function f(x)=x^2 over the interval [1,3]
B) We use disk method and f(x) is function of variable x, so we <span>rotate the curve about the x-<span>axis.


2. Shell method.

In this case volume is given by:

</span></span>\boxed{V=2\pi\int\limits_a^bx\cdot f(x)\,dx}

So there will be:

V=\pi\int\limits_1^3x^4\,dx=\dfrac{2}{2}\cdot\pi\int\limits_1^3x^4\,dx=2\pi\int\limits_1^3\dfrac{x^4}{2}\,dx=&#10;\boxed{2\pi\int\limits_1^3x\cdot\dfrac{x^3}{2}\,dx}

A) Function f(x)=\dfrac{x^3}{2} over the interval [1,3]
B) We use shell method and f(x) is function of variable x, so we <span>rotate the curve about the y-<span>axis.</span></span>

zepelin [54]

Answer:

(0, <u>3</u>), (2, <u>-1</u>), (-6, <u>15</u>)

Step-by-step explanation:

I recommend you use desmos scientific calculator for these problems.

So first you'll wan't to plug in the expression:

y=-2x+3

Then you''l want to put x= then the domains.

x=0, 2 or -6. (it doesn't matter as long as you put them in one at a time.)

youll then get each answer as you plug the numbers in.

x=0 y=3

x=2 y=-1

x=-6 y=15

Sorry if it wasn't clear to understand I'm doing my work at the same time as helping others.
