Answer:
Step-by-step explanation:
To solve for the leg of the missing right triangle, one must use the Pythagorean theorem. The Pythagorean theorem states the following,
Where (a) and (b) are the sides adjacent to or next to the right angle. (c) is the side opposite the right angle. Substitute in the given values and solve for the unknown,

Answer:
The instantaneous rate of change of with respect to
at the value
is 18.
Step-by-step explanation:
a) Geometrically speaking, the average rate of change of with respect to
over the interval by definition of secant line:
(1)
Where:
,
- Lower and upper bounds of the interval.
,
- Function exaluated at lower and upper bounds of the interval.
If we know that ,
and
, then the average rate of change of
with respect to
over the interval is:
The average rate of change of with respect to
over the interval
is 27.
b) The instantaneous rate of change can be determined by the following definition:
(2)
Where:
- Change rate.
,
- Function evaluated at
and
.
If we know that and
, then the instantaneous rate of change of
with respect to
is:
The instantaneous rate of change of with respect to
at the value
is 18.
