Answer:
x ≤5
Step-by-step explanation:
There is a closed circle at 5 so that means equals
The line goes to the left so that means less than
x ≤5
I assume you need the difference between the percentages,
if
132 mil...........................100%
9.2 mil............................x
x=(9.2 mil * 100)/132= 6.96%
142 mil...........................100%
13.4 mil..........................y
y=(13.4 *100)/142= 9.43%
the difference is
9.43-6.96=2.47 %
Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.
