To answer your question, let's first break down the question in its most simplest terms:

• Isosceles triangle: A triangle that has (at least) two equal sides.

• Equilateral triangle: A triangle on which all of its sides are equal.

- Therefore, an equilateral triangle is a special case of an isosceles triangle having not just two, but all three sides and angles equal.

- Therefore, all isosceles triangles are NOT equilateral.
• However, all equaliteral triangles are isosceles.

Write the expression as a product:<br><br> 1–(2x–1)^2

postnew [5]

Answer:

$1- ( { 2 x - 1)}^{2} = 4x (1 - x )$

Step-by-step explanation:

We want to to rewrite

$1 - ( { 2 x - 1)}^{2}$

Use difference of two squares to get:

${a}^{2} - {b}^{2} = (a + b)(a - b)$

This implies that:

${1}^{2} - ( { 2 x - 1)}^{2} = (1 +( 2x - 1))(1 - (2x - 1))$

${1}^{2} - ( { 2 x - 1)}^{2} = (1 + 2x - 1)(1 - 2x + 1)$

This finally simplifies to:

${1}^{2} - ( { 2 x - 1)}^{2} = 2x (2 - 2x )$

Therefore the required product is

$2x (2 - 2x ) = 4x(1 - x)$

Find the area bounded by the graphs of the indicated equations over the given interval.

NeX [460]

Answer:

48

Step-by-step explanation:

$y = 0$

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.

$y = {x}^{2} - 25$

We then get

$\frac{ {x}^{3} }{3} - 25x$

Evaluate at -3

$\frac{ - 3 {}^{3} }{3} - 25( - 3)$

$- 27 + 75 = 48$

Then we evaluate at 0

$\frac{0 {}^{3} }{3} - 25(0) = 0$

Next, we subtract the the answer then we get

$48 - 0 = 48$

Phil has two rectangular prisms. The height of the second prism is 1/2 times the height of the first prism. The lengths and widt

Vesnalui [34]

The volume of the second prism is also ten times the volume of the first prism.

Let's assume that both prisms have:

width = 3 units

height = 4 units

Prism 1 length = 5 units

Prism 2 length = 50 units

Let's solve their respective volumes to compare...

Volume of prism 1 = length * width * height

= 5 * 3 * 4

= 60 units ^3

Volume of prism 2 = 50 * 3 * 4

= 600 units ^3

Prism 2/ prism 1 = 10

That means prism 2 is ten times the volume of prism 1.
