Step-by-step explanation:
Hello, please consider the following.
When the parabola equation is like
The vertex is the point (h,k) and the focus is the point (h, k+1/(4a))
As the vertex is (3,-2) we can say that h = 3 and k = -2.
We need to find a.
The focus is (3,2) so we can say.
So an equation for the parabola is.
Hope this helps.
Do not hesitate if you need further explanation.
Thank you
Answer:
a.
Step-by-step explanation:
Usually, we represent losses with negative numbers. Using that representation, a loss of $975 would be represented by the integer -975.
__
The additive inverse of this number is also called its "opposite." It is found by changing the sign: additive inverse = +975.
__
The sum of a number and its additive inverse is zero. The opposite of a loss is a gain. The value +975 represents the gain (the investment's earnings) that would bring the net change in investment value back to zero.
