PLEASE HELP

Answer:

he shortest distance from the point E to a side of square ABCD is 0.293

Step-by-step explanation:

The question parameters are

Shape of figure ABCD = Square

Point E lies on the diagonal line AC

The length of the segment AE = 1

Therefore, we have;

Length of AC = √(AB² + CD²) = √(1² + 1²) = √2

Hence, the point E is closer to the point C and the closest distance to a side from E is the perpendicular from the point E to BC at point E' or to CD at poit E'' which is found as follows;

AC is a bisector of ∠DAB, hence;

∠DAC = 45° = ∠CAE'

EE' = EC × cos(45°)

EC = AC - AE = √2 - 1

Therefore;

EE' = (√2 - 1) × cos(45°) = (√2 - 1) × (√2)/2 = 1 - (√2)/2 = 0.293

Hence, the shortest distance from the point E to a side of square ABCD = 0.293.

PLEASE!!!!!!!The adjoining figure shows two circles with the same center. The

<h3>Answer:</h3>

$\boxed{\boxed{\pink{\sf \leadsto Hence \ the \ area \ of \ shaded \ region \ is 264 cm^2}}}$

<h3>Step-by-step explanation:</h3>

Here , two circles are given which are concentric. The radius of larger circle is 10cm and that of smaller circle is 4cm . And we need to find thelarea of shaded region.

From the figure it's clear that the area of shaded region will be the difference of areas of two circles.

Let the,

Radius of smaller circle be r .
Radius of smaller circle be r .
Area of shaded region be $\bf Area_{shaded}$

$\bf \implies Area_{Shaded}= Area_{bigger}-Area_{smaller} \\\\\bf\implies Area_{Shaded} = \pi R^2 - \pi r^2 \\\\\bf\implies Area_{shaded} = \pi ( R^2-r^2) \\\\\bf\implies Area_{shaded} = \pi [ (10cm)^2 - (4cm)^2] \\\\\bf\implies Area_{shaded} = \pi [ 100cm^2-16cm^2] \\\\\bf\implies Area_{shaded} = \pi \times 84cm^2 \\\\\bf\implies Area_{shaded} = \dfrac{22}{7}\times 84cm^2 \\\\\bf\implies \boxed{\red{\bf Area_{shaded} = 264 cm^2 }}$

<h3>Hence the area of the shaded region is 264 cm².</h3>

Create a 3rd degree polynomial and divide it by x-2. Show all steps. WILL MARK BRAINLEST!

Oksi-84 [34.3K]

Step-by-step explanation:

Monomial = x^2, 1 term

Binomial = x^2 + x, 2 terms

Trinomial = x^2 + x + 3, three terms

Binomial is more than 3 terms

Let's do a 3rd degree polynomial like:

${x}^{3} + 2x^{2} + 4x + 8$

Now let's put parenthesis around (x^3 + 2x^2) and (4x + 8)
Let's treat both of these as seperate for now. In the first part, you can see an x^2 can be factored out of it
