Answer:
Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form. 3x + 4y = 12. 4y = –3x + 12.

Answer:
60.6
Step-by-step explanation:
The formula for finding the circumference of a circle is C = 2πr
C is circumference, π is pi (we'll just us 3.14 here), and r is radius.
The radius is found by dividing the diameter in half.
19.3/2=9.65
So the equation should look like this:
C = 2(3.14)(9.65)
C = 60.602
C = 60.6
Answer:
Dy/dt = 11.67 ft/s
Step-by-step explanation: See Annex
In Annex, Triangles ACE and BCD are similar then, we can write
( y- x ) / y = 6 / 15
15*y -15*x = 6*y
15*y - 6*y = 15*x
9*y = 15*x
y = (15/9)*x
Differentiating with respect time on both sides of the equation we get
Dy/dt = (15/9) Dx/dt (1)
Where we know Dx/dt = 7 ft/s, and according to (1) Dy/dt does not depend on x (distance between man and the pole, only depend on the speed f the man
Dy/dt = (15/9) * 7
Dy/dt = 11.67 ft/s
