Answer:

Step-by-step explanation:
To find the slope of the equation use
.
So,
=
. Now we can use our slope and any of the two points to write in point-slope form, which is
. Using the point (7,-6), the formula will give
.
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
Answer:
4ft
Step-by-step explanation:
500=pir^2h
r^2=500/(10*pi)
r=3.989ft
Answer:
148 degrees
Step-by-step explanation:
32*2 = 64;
296/2 = 148 degrees.
19^2 or 361 is the answer to the equation
Answer:
Step-by-step explanation:
hello :
if : r the radius ( r ≠0)
the circumference is : 2πr
the area is : πr²
so : πr² = 2πr
simplify by : r π you have : r=2
