Answer:
Step-by-step explanation:
First consider the unknown original price as 'x'.
Then consider the rate of discount.
To find the actual discount, multiply the discount rate by the original amount 'x'.
To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price.
15 percent of 359 is 53.85
subtract 359 minus 53.85 and you get 305.15

- Sine of an angle = Opposite side/Hypotenuse
- Cosine of an angle = Adjacent side/Hypotenuse
- Tangent of an angle = Opposite side/Adjacent side
These three operators can be thought of as ratios of certain sides of a triangle. A ratio is just a comparison of two quantities; or lengths of the sides in this case.
If it has no real solutions, that means the graph does not intersect the x axis
since we have ax^2+bx+c=0, the parabola opens either up or down
since the vertex is in the second quadrant (x is negative and y is positive in this reigon) and the graph does not cross the x axis, the parabola must open up
if the value of 'a' is positive, then the parabola opens up
so 'a' must be positive
if it is translated to the 4th quadrant, then the vertex is now below the x axis
it will now have 2 x intercepts because the vertex is in the 4th quadrant and look at a graph of a parabola opening up with vertex in 4th quadrant and seehow many time it crosses the x axis
