Answer:

(0, 28)

Step-by-step explanation:

dilation means like "projection".

like when you have a projector at home or at school and watch a movie or so on a projection screen.

the father away from the projector, the bigger the picture. and, with a zoom lens this scaling factor (how much bigger) can be changed.

now when it says here that the points of the rectangle are dilated (or projected) with scale factor 7 from the origin (0, 0), it just means the projector light bulb is at (0, 0).

the images to be projected are at the QUAD coordinates.

and the protection screen is 7 times farther away from the projector light bulb than the original images.

so, U' = (7×0, 7×4) = (0, 28)

Determine whether the following series converge or diverge

Mars2501 [29]

An alternating series $\sum\limits_n(-1)^na_n$ converges if $|(-1)^na_n|=|a_n|$ is monotonic and $a_n\to0$ as $n\to\infty$ . Here $a_n=\dfrac1{\ln(n+1)}$ .

Let $f(x)=\ln(x+1)$ . Then $f'(x)=\dfrac1{x+1}$ , which is positive for all $x>-1$ , so $\ln(x+1)$ is monotonically increasing for $x>-1$ . This would mean $\dfrac1{\ln(x+1)}$ must be a monotonically decreasing sequence over the same interval, and so must $a_n$ .

Because $a_n$ is monotonically increasing, but will still always be positive, it follows that $a_n\to0$ as $n\to\infty$ .

So, $\sum\limits_n(-1)^na_n$ converges.

Here is a circle touching a square.

Alex Ar [27]

Answer: 9πcm²

Step-by-step explanation: area of the square= 36cm²

Therefore, the area of one side= √area = √36 = 6cms

Since the circle is touching the sides of the square, the side of the square = the diameter of the circle

Therefore the radius of the circle= side/2 = 3cm

The formula for the ares of the circle is πr²

π*3*3 = 9πcm²
