Honestly idk you’ll need a better way to explain this
The shape of this graph is
Answer:
Linear equation is 
Step-by-step explanation:
We have,
Total monthly income (in dollars) = y
Number of times an app is opened = x
As, the advertiser pays $0.002 each time an app is opened.
So, the amount paid by the advertiser if an app is opened x times = 0.002x dollars.
Since, $30 per month is also paid by the advertiser.
Thus, total monthly income 'y' is given by,

Hence, the graph of the linear equation is given below.
Answer:
or 3.14
Step-by-step explanation:
The formula for the area of a circle is 
If this quarter circle were to be a full circle, the area would be 
Since this is a quarter circle as the angle is 90 degrees (which is a quarter of 360), the area of this shape is
.
k = 0 means the parabola has one zero, because the vertex is just on the x-axis. k > 0 means the parabola has none zeros, because the vertex will be above the x-axis and it will not intersect the x - axis.
