V = speed of light = 3 x 108 m/s
d = distance = 384000 x 103 m = 3.84 x 108 m
time taken = t = d/V = 3.84 x 108 /(3 x 108 ) = 1.28 sec
<span>(a^2+b^2)^2
since (a+b)^2=a^2+2ab+b^2, substitute a with a^2 and b with b^2, which yields:
a^4+2(a^2*b^2)+b^4</span>
You multiply 86 x .45 and you get the answer of 38.7
The answer would be A. The triangle with the 70 seems to be isosceles and that means that two of the angles equal 70. 70+70=140. Subtract 140 from 180 to find the third angle because every triangle has a total of 180 degrees. Due to the fact that x and the 40 degrees are on the same line, they will equal 180 degrees. So, 180-40=140. X=140. I hope this helps
