Answer:
The one that has the lowest point at 5 and the highest point at 15
Step-by-step explanation:
That’s the range/ highest lowest values
Answer:
what do you mean I am not understanding it sorry.
Answer:
The required formula is:
Step-by-step explanation:
The total number of squares of the the first term = 4
The total number of squares of the the second term = 7
The total number of squares of the the third term = 10
so,
Finding the common difference d
As the common difference 'd' is same, it means the sequence is in arithmetic.
So
If the initial term of an arithmetic progression is and the common difference of successive members is d, then the nth term of the sequence is given by:
Therefore, the required formula is:
The next step Javier needs to take in order to evaluate the expression is to simplify it to it's lowest term. Details below
<h3>Data obtained from the question</h3>
- Expression = 2a³ - 1
- Evaluation =?
<h3>How to evaluate the expression</h3>
From the question given, we were told that Javier submitted 2 for a
Thus, the new expression becomes
2 × 2³ - 1
Recall
Aⁿ × Aᵐ = Aⁿ⁺ᵐ
Thus,
2 × 2³ = 2¹⁺³ = 2⁴
Therefore,
2 × 2³ - 1 = 2⁴ - 1
But
2⁴ = 16
Thus,
2⁴ - 1 = 16 - 1
2⁴ - 1 = 15
Therefore,
2 × 2³ - 1 = 15
