A computer can sort [tex]\( x \)[/tex] objects in [tex]\( t \)[/tex] seconds, as modeled by the function:
[tex]\[ t = 0.005x^2 + 0.002x \][/tex]

How long, in seconds, will it take the computer to sort 10 objects?

Round your answer to the nearest hundredth of a second.



Answer :

To determine how long it will take the computer to sort 10 objects, we will use the given function:
[tex]\[ t = 0.005 x^2 + 0.002 x \][/tex]
where [tex]\( x \)[/tex] is the number of objects, and [tex]\( t \)[/tex] is the time in seconds it takes to sort [tex]\( x \)[/tex] objects.

1. Substitute [tex]\( x = 10 \)[/tex] into the function:

[tex]\[ t = 0.005 (10)^2 + 0.002 (10) \][/tex]

2. Calculate [tex]\( (10)^2 \)[/tex]:

[tex]\[ (10)^2 = 100 \][/tex]

3. Substitute and simplify:

[tex]\[ t = 0.005 \times 100 + 0.002 \times 10 \][/tex]

[tex]\[ t = 0.5 + 0.02 \][/tex]

4. Add the terms:

[tex]\[ t = 0.52 \][/tex]

So, the time [tex]\( t \)[/tex] taken to sort 10 objects is [tex]\( 0.52 \)[/tex] seconds.

5. Round to the nearest hundredth:

[tex]\[ 0.52 \text{ seconds} \][/tex]

Thus, it will take the computer 0.52 seconds to sort 10 objects.
