If b=a+3, then (a-b)^4=?

thus calculating the if a=0; b=3, answer is (A.) taking second answer 27, a and b can't be whole nos. the rest three answers are not possible as cube of any no. would be positive and not a negative no. thus the answer is A.

Step-by-step explanation:

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

yes

yes yes yes
