Anything between the decimal and last non-zero digit
so 00025 are significant
the 0 in front is insignificant because it could be
00000.00025
zeroes after the 25 don't matter becasue it could be
0.000250000000 and it wouldn't change
the sig figs are 00025
(cos Ф -cos Ф)² + (cos Ф + cos Ф)²
Firstly: (cos Ф -cos Ф)² = 0² = 0
Secondly :(cos Ф + cos Ф)² = (2cos Ф)². = 4. (cos Ф)² = 4cos² Ф
Mind you when you raise a cosine (or sin or tan...) to the n power, the n power should affect the cosine only and NOT the angle Ф

Given: 
Find: 
Solution: In order to get the equation, we need to first use the point-slope form to help us sort out our information and then we solve for y.
<u>Plug in the values</u>
<u>Simplify and solve for y</u>
Therefore, the final answer would be that the equation that has a slope of -1/4 and passes through (4, -5) is y = -1/4x - 4.
Answer: 10.7x + 5
Step-by-step explanation:
(3.5 + 7.2)x + (-5 + 10) = 10.7x + 5
Answer:
3=75 degrees
Step-by-step explanation:
1+2+3=6
1*150/6=25degrees
2*150/6=50 degrees
3*150/6=75 degrees
