Answer:

Yes

Step-by-step explanation:

A function correlates elements from a set one and only one element from a different set. Think of a train timetable: you can't have the same train in two points at a given time.

An easy way to solve the problem is to take a ruler (or the edge of a sheet of paper, as long as it's straight) and scan the graph parallel to the Y axis. As long as you don't touch the graph more than once, it's a function (zero points is ok!)

The answer : 4 sin c sin b sin a

Step by step
Formula = A+b+c = 180

B+c = 180-A

C+A= 180-B

A+B= 180-c

2 sin c • 2 cos a-b+c/ 2 cos a-b-c / 2

4 sin c cos 180-2b/2 cos a-(180-a)/ 2

4 sin c cos (90-b ) cos ( A-90)

4 sin c sin b sin A

ankoles [38]

10*3=30
30*3=90
90*3=270
270*3=810

or

10*3^1=30
10*3^2=90
10*3^3=270
10*3^4=810

the next two terms of this sequence are 270 and 810.

Answer:

5.1 (Rounded down to 5)

Step-by-step explanation:

What you do first is

16.8 * 24.3

this is 408.24

now you do 408.24 / 80 which is 5.1

Obviously you cant by 0.1 of a roll but you could just round that down to 5, then the little bit that isnt covered you could just buy a smaller roll of carpet or something
