I THINK it might be y=cos(x)+2. Don’t quote me on that and you might wanna check with someone else

Answer:

y = cos x + 2

Step-by-step explanation:

1. By looking at the shape of the graph, you can infer that it is either a cos or sin graph.

2. Look at the y value when X = 0. It starts with an inverted bell shape curve, from there we can infer that it is a cosine graph. if it is a sin graph, the shape will be like a toppled S shape curve.

3. This part is a bit trial and error for me:

Let X = 0,

cos 0 = 1

But the graph shows that when X = 0, Y = 3,

So there are 2 possibilities:

  • 3 cos X
  • cos X + 2

However when X = π,

  • 3 cos π = -3
  • cos π + 2 = 1

So cos x + 2 is the only option.

Hope it makes sense to you. Sorry if it sounds confusing, English is not my first language.

Which is the smallest number? 3/4,1/5,10/23,2/31
bixtya [17]
A quick and easy way to do this particular question is to think all of these numbers are close to 1/2 except 2/31. So, the lowest is 2/31.

Pleasee help me with this anyone..
vlabodo [156]

Answer:

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15

sergiy2304 [10]
A = LW
A = 188
W = 4

188 = 4L
188/4 = L
47 = L....so the length is 47 meters

Given the equation 2x = 4y - 3 write another linear equation that would create a system that has the number of solutions listed
Harman [31]

Answer:

A. 2x-4y=\pi
B.  x=1

C. 2x-4y=3

Step-by-step explanation:

A. 2x-4y=\pi. Any number could work as long as the coefficients for x and y stays the same. You are basically imposing that the quantity 2x-4y (if you bring 4y to the LHS) is equal to both -3 AND \pi, or any number you like. But yesterday was 3/14 so let's pick a fun number!

B.  x=1 Or y=1. Or as long as you don't pick the same ratios of x and y you're golden. But x=1 is the easiest that comes to mind

C. 2x-4y=3. To get infinitely many solutions you just have to rewrite the equation again. Maybe move things around if you prefer, or multiply everything by a number you lile.
