In both cases, we have cooling. We can add together the 2 functions describing this cooling: z(x) = 0.5x - 9 - [-x-2] = 0.5x - 9 + x + 2, or
z(x) = 1.5x - 7
Provided that this is correct, all we have to do now is to subst. 5 for x:
z(5) = 1.5(5) - 7 = 7.5 - 7 = 0.5 (answer)
Accuracy can be defined as the closest result to the actual or true value.
when you are measuring a quantity, there are many factors that can impact on the accuracy of the measurement that are:
measuring instrument, if the measuring instrument is old and not working correctly or may be you do not know how to handle or use the measuring instrument correctly you will never get accurate result.
sometime working environment can also be the reason for not to get accurate result and skill of a person about how to measure correctly as i mentioned earlier can also lead to inaccurate result.
The answer is: She had more math assignments to start with, but completed more science assignments weekly.
