150,000,000 km =
1.5 x 108 km
1*10^-14/4.2*10^-6 =
[1/4.2] * 10^-14 / 10^-6 =
0.2380952380952381 * 10^6 / 10^14 =
0.2380952380952381 * 10^-8 =
2.380952380952381 * 10^-9 [ approx.]
76(5+9)-981+2500(9) adding inside the parentheses first we have
76(14) - 981 + 2500(9) next, we perform any mutiplications before additions/subtractions
1064 - 981 + 22500 now, we just perform any additions/subtractions as we encounter them from left to right.....so we have
1064 - 981 + 22500 = 22583
The common denominator is 20.....so we have
8/20 + 15/20 = 23/20
Remember that the arctangent returns an angle from ( -90 , 90 )
In this case the angle is -26.6°....so we would actually add this to 360° to get the correct positive angle of 333.4°
2^100 = 1,267,650,600,228,229,401,496,703,205,376
[ approximately, 1.267 nontillion.!!!! ]
-2(6+x)<-16+2x simplify the left side
-12 - 2x < -16 + 2x add 16 , 2x to both sides
4 < 4x divide both sides by 4
1 < x or, put another way, x > 1
Fahrenheit 451 - Ray Bradbury
The Grapes of Wrath - John Steinbeck
The Count of Monte Cristo - Alexandre Dumas
The Adventures of Sherlock Holmes - Sir Arthur Conan Doyle
These should get you started......[ I highly recommend the second one.....my favorite book of all time....!!!]
Very nice, Dragonlance........
We can use the tangent inverse to solve this....so we have
tan-1(400/300) = about 53.1° [ this is the angle of depression]
