The number of units produced by the worker during t hours of work can be modelled by the following function:

To find the number of units produced during first 3 hours, we can substitute 3 for t. This will give us the number of units produced by the worker during first 3 hours.

Thus the worker will produce 67 units during the first 3 hours of the work.
We know that, 1 litre = 1000 ml
Then, 2 litres = 2000 ml
Hence, the required ratio of 1000 ml to 2000 ml be
= 1000 : 2000
= 1 : 2
Answer:
10
Step-by-step explanation:
Distance = √(x2-x1)² + (y2-y1)²
d = √(10-4)² + (13-5)²
d = √6² + 8²
d = √36+364
d = √100
d = 10
Answer:what grade u in
Step-by-step explanation:
Rule: second differences are 2.
Selection C is appropriate.
_____
First differences are the sequence of differences of the given numbers:
.. 3 -8 = -5
.. 0 -3 = -3
.. -1 -0 = -1
.. 0 -(-1) = 1
Second differences are the sequence of differences of these:
.. -3 -(-5) = 2
.. -1 -(-3) = 2
.. 1 -(-1) = 2
All of these are 2, so the sequence can be described by a *second* order polynomial (because *second* differences are a non-zero constant).
