Answer:
$286.80
Step-by-step explanation:
First, find the price after the 150% markup:
478(1.5)
= 717
Now, calculate the price with the 60% discount:
717(0.4)
= 286.8
= $286.80
Answer:
The correct option is 2. The circle has a radius equal to 7.
Step-by-step explanation:
It is given that center of a circle is at the origin on a coordinate grid.
The standard form of the circle is
Where (h,k) is center of the circle and r is radius.
The equation of the circle is
The line intersects the circle at (0,7) it means the point lies on the circle.
Put x=0 and y=7 in the above equation.
Therefore the radius of the circle is 7 units.
The line is passing through the point (0,7) with positive slope. Two points are required to find the slope of a line.
Since we have a single point therefore we cannot find the slope of the line. Second option is correct.
