$2 = 5 coasters
x = 60 coasters
60 / 5 = 12
12 x $2 = $24
$24 = 60 coasters
$5 = 2 coasters
60 / 2 = 30
30 x $5 = $150
$150 - $24 = $126
$126 in profit
Could you make this easier to read, perhaps by ensuring that you have copied the original problem exactly?
What I read, which may or may not be correct, is:
15x^2 - 35x + 24.
I graphed this on my calculator and found that the graph, a parabola opening up, never touches or crosses the x-axis. Thus, the given equation has no real roots.
If you were to find the discriminant, b^2 - 4ac, you'd find that it's negative, which is another strong clue that there are no real roots.
Answer:
last one
Step-by-step explanation:
You are swinging A(-1,-2) around the center which in this case is the origin. Keep in mind that points on a circle all have a equal distance from the origin. We don't want the distance from the center to change.
We want the center of that circle to be the origin.
So the answer is the last one:
"Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A. "
To answer this you will need to write the ratio of difference in the tides over the amount of time that goes by.
1. 3.21 ft - 0.20 ft= 3.01 ft change.
2. 3.01 change over 6 5/12 hr.
3. Divide these to find the lapse rate per hour. This is about 0.47 ft per hour.
