The value of 6.8x10^2x1.3x10^-3 In standard form

0.884

Step-by-step explanation:

When you multiply exponents together, you add the powers values together.

Step 1: Multiply base numbers

6.8(1.3) = 8.84

Step 2: Multiply (add) exponentials

Step 3: Combine into scientific notation

Step 4: Evaluate into standard form

0.884

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)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
