<h2>The y-value of the vertex is 49</h2>
Step-by-step explanation:
Given,
The vertex of the parabola occurs at .
For the given parabola,
So, vertex occurs at
At this point
∴ At vertex, y-value of is 49.
The boy would have 3 brothers and 3 sisters therefore in the family there would be 4 boys and 3 girls
Let us denote the smaller even integer by
.
Then, the next even integer must be
.
To verify, set
as any even number, say
.
Then, the next even integer must be 2 more than this number, i.e.
.
The sum of these two consecutive even integers can be expressed as:
We are told that this sum divided by four is 189.5, i.e.
Multiplying both sides by 4 will reverse the division:
Subtracting 2 from each side will reverse the addition:
Dividing both sides by 2 will reverse the multiplication:
Therefore, the two consecutive integers must be
378 and
380.

Answer:
No, The 8 in the ones place of the decimal and the 8 in the thousands. Decimals go by variables of 10 if that makes sense
so hopping from the 8 in the ones place it would go 10, 100,1000.
Therefore the statement is false because the value between the eitghts is not 100 its 1000
