nata0808 [166]

Answer:

The volume of the solid is π/40 cubic units.

Step-by-step explanation:

Please refer to the graph below.

Recall that the area of a semi-circle is given by:

\displaystyle A=\frac{1}{2}\pi r^2

The volume of the solid will be the integral from <em>x</em> = 0 to <em>x</em> = 1 of area A. Since the diameter is given by <em>y</em>, then the radius is <em>y/2</em>. Hence, the volume of the solid is:

\displaystyle V=\int_0^1\frac{1}{2}\pi \left(\frac{y}{2}\right)^2\, dx

Substitute:

\displaystyle V=\frac{1}{2}\pi\int_0^1\left(\frac{x^2}{2}\right)^2\, dx

Simplify:

\displaystyle V=\frac{1}{2}\pi \int_0^1\frac{x^4}{4}\, dx

Integrate:

\displaystyle V=\frac{1}{2}\pi \left[\frac{x^5}{20}\Big|_0^1\right]

Evaluate:

\displaystyle V=\frac{\pi}{40}\left((1)^5-\left(0\right)^5\right)=\frac{\pi}{40}\text{ units}^3

The volume of the solid is π/40 cubic units.

In a conventional gradient, the amount of money in period one is known as the_________.
erik [133]

In a conventional gradient, the amount of money in period one is known as the base amount.

<h3>What is an arithmetic gradient? </h3>

An arithmetic gradient series is a cash flow series that either increases or decreases by a constant amount each period.

<h3>What is a base amount?</h3>

Base amount is the fundamental numerical assumption from which something is begun or estimated in a given arithmetic series. It usually occurs in period for a conventional gradient.

Thus, in a conventional gradient, the amount of money in period one is known as the base amount.

A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false
Ket [755]

Answer:

It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5
