Answer:
number of children ticket sold = 70
number of adult ticket sold = 70 × 3 = 210
number of student ticket sold = 500 - 4(70) = 500 - 280 = 220
The answer is 16x because if you add 10 and 2 you get 12 then add 4 you get is 16 but you need to multiply by x so you write it as 16x
<span>This intersection produces a line. However, if the angle of the plane is less than the cone's angle, then the intersection produces a point. If the angle of the plane is greater than the angle of the cone, then the intersection is two lines intersecting at the vertex. If the plane intersects at some point other than the vertex, then the intersection is a circle if the plane is perpendicular to the cone's axis. It is an ellipse when the plane's angle is less than the cone's angle. It's a parabola when the planes's angle equals the cone's angle.</span>

Step-by-step explanation:
Answer:
The number of units that must be sold in order to have the greatest revenue is 50,000 units
Step-by-step explanation:
Given;
y = -0.0002x² + 20x
where;
y is the revenue
x is the units of the product
The equation above is a quadratic equation, to obtain the value of x (units) that will give maximum value of y (revenue), we differentiate the equation.
dy/dx = -0.0004x + 20
Now, equate the differential value to zero, in order to get the value of x that will make the equation maximum.
-0.0004x + 20 = 0
-0.0004x = -20
x = (-20) / (-0.0004)
x = 50,000 units
Therefore, the number of units that must be sold in order to have the greatest revenue is 50,000 units
