Differentiate both sides with respect to
:
When
, you have
For part (b), we now assume that
and
are functions of an independent variable, which we'll call
(for time). Now differentiating both sides with respect to
, we have
where the chain rule is used on the right side. We're told that
is decreasing at a constant rate of 0.1 units/second, which translates to
. So when
, you have
where the unit is again units/second.
Answer:
He can use the factors of 36 to determine the number of groups he can divide the class into such that they are equal.
The Factors (excluding 1) are;
2, 3, 4, 6, 9, 12, 18
Using these therefore he can divide them;
- Into 3 groups each with 12 people.
- Into 4 groups each with 9 people.
- Into 6 groups each with 6 people.
- Into 9 groups each with 4 people.
- Into 12 groups each with 3 people.
Answer:
The top right grid
Step-by-step explanation:
The other grids have 2 y outputs for one or more x inputs.
5x100 or 1x500 is your answer
Answer:
900
Step-by-step explanation:
Because the unit rate of mins per mile is 7.5 min for each mile. So, then you multiply 120 with 7.5 and move the decimal place to get
