Step-by-step explanation:

and,

represents perpendicular lines.
Two lines are perpendicular when product of their slopes = -1
In, y =½x+4
m1 = ½
In y = -2x -3
m2 = -2
Now, m1× m2 = ½× (-2) = -1
Answer:A: plug it into a online graphing calculator and find the highest point and where it is on the x axis at that point
b: find the highest point and where it is on the y-axis at that point
Step-by-step explanation:
above
a. The general equation for a circle centered at
with radius
is

The described circle has equation

We know the circle passes through the origin. This means that the equation above holds for
and
. The distance between any point on the circle and its center is the radius, so we can use this fact to determine
:

So the circle's equation is

b. If the distance between point B and the center is less than
, then B lies inside the circle. If the distance is greater than
, it falls outside the circle. Otherwise, if the distance is exactly
, then B lies on the circle.
The distance from B to the center is

, so
, which means B falls outside the circle.
The software company released 227 home versions and 723 professional versions.
<h3>E
quation</h3>
Let h represent the number of home versions sold and p represent the number of professional versions sold.
Since 1000 copies where sold, hence:
Also the revenue was $38075, hence:
Solving equations 1 and 2 simultaneously gives:
h = 227, p = 723
The software company released 227 home versions and 723 professional versions.
