Answer:

16 is Potential energy and 411.6 Joules, 17 is Kinetic energy 896,000

Step-by-step explanation:

PE=mgh

2 kg(9.8m/sec^2) 21m= 411.6J

KE=1/2mv^2= 1/2(1120kg)(40m/s)^2= 896,000J

What is the slope of a line that is parallel to y = 5x + 3?
Marina86 [1]

Answer:

slope = 5

Step-by-step explanation:

The equation of a lin in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 3 ← is in slope- intercept form

with slope m = 5

Parallel lines have equal slopes , then

The slope of a line parallel to y = 5x + 3 is 5

Need some help please!!​

Answer:

The other point on the diameter which is also on the circle is; (-3, 2)

Step-by-step explanation:

The center of the circle, also a point where the diameter crosses, is (3, 6)

The diameter touches the circle at point (9, 10)

The displacement is (9 - 3, 10 - 6) = (6, 4)

This means that we move, +6 units along the x-axis and +4 units along the y-axis , from the center of the circle in order to reach point (9, 10)

If we want to reach the other point on the diameter which also on the circle, we move -6 units along the x-axis and -4 units along the y-axis to get;

(3, 6) - (6, 4) = (-3, 2)
