Answer:
The correct answer is 4294967296 possible ways to complete such a test.
Step-by-step explanation:
Step 1
The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are
ways to complete the first step,
ways to complete the second step,
, and
ways to complete the
step, this process can be carried out in
ways.
Step 2
We use the fundamental principle of counting with
for a total of
steps. This test can be carried out in
ways. This comes from multiplying 4 by itself 16 times.

Answer:

Step-by-step explanation:
We are given that
Height of man=5 foot

Height of street light=20ft
We have to find the rate of change of the length of his shadow when he is 25 ft form the street light.
ABE and CDE are similar triangle because all right triangles are similar.







Hence, the rate of change of the length of his shadow when he is 25 ft from the street light=
