Answer:
From left to right
20, 40, 0.2, 0.6
Step-by-step explanation:
y/x = k
1st chart
20/1 = 20
2nd chart
80/2 = 40
3rd chart
0.4/2 = 0.2
4th chart
4.5/7.5 = 0.6
Answer:

Step-by-step explanation:
Given:

This reads as: 256 to the power of "-4 to the power of 3/2".
Therefore, we need to deal with the "-4 to the power of 3/2" first.
Rewrite the 4 as 2²:




Therefore:

Replace "-4 to the power of 3/2" with -8 :

Rewrite 256 as 2⁸ :

Answer:
The constant in the algebraic expression to represent the pattern below is 4.
Step-by-step explanation:
Imortant Tip:
- An Arithmetic sequence has a constant difference 'd' which can be determined by computing the differences of all the adjacent terms
Given the pattern

computing the differences of all the adjacent terms

The difference between all the adjacent terms of the pattern is the same which is

Hence, the given pattern represents the Arithmetic sequence.
Therefore, the constant in the algebraic expression to represent the pattern below is 4.
Add 16.7m 4 times that should be the correct answer if not sorry
