Answer:
The answer is letter B.
Explanation:
The option that will most effectively
reduce her or his radiation exposure to that source is Standing 8 ft from the source for 2 minutes.
The recursive formula of the explicit formula
is 
The explicit formula is given as:

When n = 1, we have:


When n = 2, we have:


When n = 3, we have:


So, we have:



Rewrite the functions as follows:



So, we have:



Express 2 as 3 - 1

Substitute n for 3

Hence, the recursive formula is

Answer:
Explanation:
The formula for the work done on a spring is:

where k is the spring constant and x is the change in length of the string
For the first statement,
x = (a-1.1), W = 5
=> 
Now making k the subject of formula, we have:

For the second statement,
x = (a-4.8), W = 9
=> 
Now making k the subject of formula, we have:

Equating A and B since k is constant, we have:

solving for the value of a

solving for a, we get:
a = 2.6801 or -9.7301
but since length cannot be negative, a = 2.68m
substituting the value of a in equation B, we have:

k = 4.005
Answer:
Thunderbolt 3
Explanation:
Bayley certainly needs the fastest connection possible for his work. The best connection type for this kind of work is the Thunderbolt 3. Thunderbolt 3 is an improvement of the previous Thunderbolt 2 developed by Intel. Thunderbolt 3 has two times the speed of Thunderbolt 2. Theoretically, its maximum throughput is approximately 40 Gbps.
