Which figure will tessellate the plane? A. regular pentagon B. regular decagon C. regular octagon D. regular hexagon

<h3>Answer: D. regular hexagon</h3>

A hexagon is composed of 6 congruent equilateral triangles. Each equilateral triangle has interior angle of 60 degrees. Adding 6 such angles together gets you to 360 degrees. So we've done one full rotation and covered every bit of the plane surrounding a given point. Extend this out and you'll be able to cover the plane. A similar situation happens with rectangles as well (think of a grid, or think of tiles on the wall or floor)

In contrast, a regular pentagon has interior angle 108 degrees. This is not a factor of 360, so there is no way to place regular pentagons to have them line up and not be a gap or overlap. This is why regular pentagons do not tessellate the plane. The same can be aside about decagons and octagons as well.

A credit card company charges 24.99% annually for its interest rate. There is a a 2450 balance.how much interest would be charge
BaLLatris [955]

A credit card company charges 24.99% annually for its interest rate

Total balance = 2450

we have to find the interest which would be charged in dollars

So to find the interest which would be charged in dollars we have to multiply total balance by the interest rate which is 24.99 and then divide it by hundred

so our interest comes = 2450*24.99/100 which comes out to be 612.255

A square has an area of 100m^2 . What is the length of each side?
Lorico [155]

Answer:

10 meters

Step-by-step explanation:

The area of a square is found by

A = s^2 where s is the side length

100 = s^2

Take the square root of each side

sqrt(100) = sqrt(s^2)

10 =s

What is the common ratio of the geometric sequence below?<br><br> 625, 125, 25, 5, 1, ...
larisa [96]

Answer: 1/5 or 0.2

Step-by-step explanation: each number is just dividing by 5

like 625/5 = 125

125/5 = 25

25/5 =5

5/5 = 1

similarly 1/5 = 0.2 or 20%

which statement correctly descibes what happens to the shape and location of the graph of y=2x^2 if it is regraphed as y=-1/2x^2
lbvjy [14]
I dont have options but i can sayEach of these questions is asking you to figure out how g(x) would be graphed based on some other function, f(x), except we're gonna make some changes to f(x) first. For example, let's look at part (a).  You're told that g(x) = 2f(x)+3.  1. Whatever f(x) is, 2f(x) would take all of the y values and double them.2. Whatever that turns out to be, "+3" would add 3 to every y value. So, to translate (1, -2), first we double the y value...so that'd be -2 * 2, or -4.  Then we add 3, which gives 1.  So, the point (1, -2) becomes (1, 1).  [EDIT:  Um, no, -4 + 1 isn't 1.  It's -1.  My bad!  MBW] Part (b) is a little bit trickier: 1.  Whatever f(x) is, by adding 1 to x, it actually shifts the graph left by 1, even though it sorta feels like you should be shifting it 1 to the right.  Let's not get too far into the details here, so for the moment, f(x+1) means "shift the graph of f to the left by 1."  In other words, subtract 1 from x to get the new point. 2.  Whatever f(x+1) is, then the "-3" would subtract 3 to every y value. So, if (1, -2) was on the original graph, then f(x+1) would be shifted to the left by 1...so that's (0, -2).  And then, we subtract 3 from y, so that'd be (0, -5).  Basically, anything inside the parentheses, like f(x+1), messes with the x coordinate of the point, and anything outside the parentheses, like -f(x) or f(x) + 3, messes with the y coordinate. For the last two, I'll give you a few hints and see if you can take it from there. For part (c):  f(2x), even though you think it might double the value of x, actually divides the value of x by 2.For part (d):  the trick here is to ignore the "-x" until the last step.  Deal with the f(x-1) first (which shifts the x coordinate...which way?), then the negative outside of f(x) (which flips the sign of the y coordinate), then the +3 outside of f(x)...and then, at the end, the "-x" would flip the sign of the x coordinate.  I hope this helps point you in the right direction!
