A) by completing the square... X^2-8x+16+20-16 = (x^2-4)^2 +20-16=(x^2-4)+4
B) Since the coefficient of x^2 is positive, it is a quadratic function which increases positively. You know that it will always be above the x axis and therefore positive since the vertex is at (4,4) and increasing
Answer:
x = 16
Step-by-step explanation:
First, find hypotenuse using 18 and 16.
Using Pythagorean theorem, it gives 24.08
now use it again with the hypotenuse and (36/2) = 18
This gives us x = 16
Holding what.......? can u be more specific?
Percentage of school taxes that need to be paid for a local district = 2.5%
Amount of income made by the Smith Household per year= $80000
Amount of money paid by the Smith's per year as school taxes = (2.5/100) * 80000
= 2.5 * 800
= 2000 dollars
So $2000 is the amount that the Smith's household needs to pay as school taxes every year. I hope the procedure needs no further clarification and the answer is what you were looking for.
The correct answer is c . E
