Answer:
If you reflect point x across the y axis, it will end up at (-1/2,0).

Answer:
1/18
Step-by-step explanation:
The probability of rolling a 1 is 1/6 because there are 6 numbers. You multiply that probability by the probability of getting a 2 or 3 which is 2/6 or 1/3 to get 1/18.
Answer:
B(x)=(x_4)^2+5 that is the answer
<span>OK, here's a *very* approximate "creative" method:
</span><span>
sin(a+b)=sin(a)cos(b) + cos(a)sin(b) </span>
<span>
choose a=30deg and b=5deg </span>
- sin(a)=0.5 (exact)
- b is a small number so we say sin(b)~b (in radians). We can do a long division for this: 3.14/36 = 0.087 radians
- similarly, for b sufficiently small, cos(b)~1
<span>- now we only need cos(a) = sqrt(3)/2. We can approximately calculate sqrt(3) as 1.73, (by trial-and-error or better, by using the Babylonian method; so sqrt(3)/2 = 0.865 </span>
<span>
Finally, sin(30 + 5) = (0.5 x 1) + (0.087 x 0.865) = 0.575 (calculating more digits is of no use because the sin(b)=b and cos(b)=1 are quite inaccurate approximations). </span>
<span>So that wasn't all too much effort, and we're close to the correct answer (0.574)
