cos(0) = 1
sin(pi/2) = 1
cos(pi/2) = 0
sin(pi) = 0
cos(pi) = -1
sin(3pi/2) = -1
cos(3pi/2) = 0

What ratios that are equivalent to 4 to 7.
expeople1 [14]
4 to 7 =  4/7

5/8 is not.

12/20 = 6/10 = 3/5 . It is not equivalent.

8:14 = 4 : 7 .  It is equivalent

5 to 10 = 1 to 2.  It is not.

16/28 = 8/14 = 4/7.  It is equivalent.

9 to 16 = 9 to 16.  It is not equivalent.

So only 8:14 and 16/28  are equivalent to 4 to 7.

yuradex [85]

Answer:

12

Step-by-step explanation:

"ba" means "b * a", where * is multiplication. So, we want to find the product of a and b.

We know a = 3 and b = 4, so we just plug these in: 3 * 4 = 12.

Thus, ba = 12.

Hope this helps!
