Answer:
nth term = n^2 + 3.
Step-by-step explanation:
4 7 12 19 28
Differences 3 5 7 9
Differences 2 2 2
So the nth term contains n^2.
4 7 12 19 28
Values of n^2 1 4 9 16 25
Differences 3 3 3 3 3
So the nth term = n^2 + 3.

Focus: ( 4, 1 )
Directrix: y = 5
The vertex is always half of a distance between the focus and the directrix.
The vertex must be at: ( 4, 3 ), h = 4, k = 3
|p| is the distance between the vertex and the directrix ( which is over the vertex and p is negative ). p = - 2
The equation:
( x - h )² = 4 p ( y - k )
( x - 4 )² = -8 ( y - 3 )
Step-by-step explanation:
After a white marble is chosen:
Now there are 25 (13 + 12) total marbles.
Without replacing the white marble we chose already, what is the probability of choosing another white marble?
Well, now there are 12 white marbles to choose from, out of a total of 25 marbles. This means our probability is:
This in decimal form is:
0.4800
The expression that can complete the blank is 6y^3
<h3>What are expressions?</h3>
Expressions are mathematical statements that are represented by variables, coefficients and operators
<h3>How to complete the blanks?</h3>
The expression is given as
2/y^2=_/3y^5
Replace the blank with x
So, we have
2/y^2 = x/3y^5
Multiply both sides of the equation by 3y^5
So, we have
x = 3y^5 * 2/y^2
Evaluate the products
x = 6y^3
This means that the blank is 6y^3
