Answer:
Option B) There is a 3 percent increase in the savings account each year.
Step-by-step explanation:
we have
This is a exponential function of the form
where
M(x) represent the amount of money in a saving account
x represent the number of years
a is the original deposit (y-intercept)
b is the base
r is the rate or percent increase
The percent increase per year is the base of the exponential function decreased by 1.
so
In this problem we have
---> original deposit
Therefore
The percent increase per year is 3%
There will be four ways a circle and a parabola can intersect because the solution of the quartic equation will be 4.
<h3>What is a circle?</h3>It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle and a parabola:
As we know the standard form of a circle:
The standard form of the parabola:
If we plug the value of y from the parabola equation in the circle equation, we get a quartic equation(4th order equation)
The solution of the quartic equation will be 4.
Thus, there will be four ways a circle and a parabola can intersect because the solution of the quartic equation will be 4.
