g(x) = a•bˣ
1: selection 2
2: selection 4
3. You want the result of evaluating 4000*(1.06)⁵ ≈ 5352.90, selection 2.
Answer:

Step-by-step explanation:
we know that
The directrix of the parabola is perpendicular to the axis of symmetry of the parabola
In this problem the directrix is y=-3.5
so
The axis of symmetry is parallel to the y-axis
we have a vertical parabola
Also, the vertex is at the origin
That means-----> the parabola open upward
The equation of a vertical parabola can be written as

where
p is the distance between the vertex and the directrix
In this problem
the distance between the vertex and the directrix is 3.5
----> the value of p is positive because the parabola open upward
substitute


isolate the variable y

Answer:
x=3
Step-by-step explanation:
1/2(2-4x)+2x=13
1-2x+2x=13
4x=13-1
x=12/4
x=3
Answer:
9x^2-25=(3x-5)(3x+5)
Step-by-step explanation:
9x^2-25=(3x)^2 - 5^2 =(3x-5)(3x+5)
A^2 - B^2 =(A-B)(A+B)
We are asked to determine if the number sets 1857300 and 1857800 are the same number sets. To answer this, we need to recall and define that number sets are a collection of distinct objects such as elements and numbers. The answer to this question is that these two sets are NOT the same, the first one contains "3" while the second one contains "8".
