(1.6 x 10^8)(5.8 x 10^6)
---------------------------------
(4 x 10^6)
multiply the numbers and add the exponent for the numerator
(1.6 x 5.8) x 10^(8+6)
---------------------------------
(4 x 10^6)
(9.28) x 10^(14)
---------------------------------
(4 x 10^6)
divide the numbers and subtract the exponents for division
(9.28/4) x 10^(14-6)
2.32x 10^(8)
Choice B
13. You add the 8 and the 5
The rate is $12 an hour, this is your slope plus $8 and your y- intercept. So by the slope intercept formula:
where m is your slope and b the y - intercept we have:
Cos ( 390)
- 4 cot (-45)
Csc (60)
Hope this helps
