Answer:
Step-by-step explanation:
The zeros are where the graph intersects the x-axis
x = 0
x = 2
x = 4
------------------------
Extra Credit
Note x = 2 is a double zero since it touches, but does not cross the x-axis
The equation is
y = -x(x - 2)²(x - 4)
Answer:
209.25 ft²
Step-by-step explanation:
2.7cm * 5 = 13.5 ft
3.1cm * 5 = 15.5 ft
Area
a = 13.5 * 15.5
a = 209.25 ft²
When a point is reflected across the x-axis, it's y value is flipped. Here is a formula for your future reference:
X-axis reflection: (x,-y)
Using your given coordinates, you simply plug the numbers in, resulting in final coordinates of (5,3.5).
Because the problem asks for the distance between the two points, you now have to find the difference between -3.5 and 3.5, which is 7.
There you go; the distance between the points is 7 units.
Let x represent the number of song downloads and let y represent the total cost
y=0.95x+70
