Answer:

y + 1 = 3(x - 8)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b ) = (8, - 1 ) , then

y - (- 1) = 3(x - 8) , that is

y + 1 = 3(x - 8)

What is the kinetic energy of a 1500 kg object moving at a velocity of 10 m/s?
DiKsa [7]

Answer: The Kinetic Energy Formula is: KE = mass x velocity^2 / 2

Plug in the correct numbers into the variables

KE = 1500 kg x 10 m/s ^2 / 2

Square the 10 m/s

KE = 1500 kg x 100 m/s / 2

Multiply

KE = 150,000 / 2

Divide

KE = 75,000 Newton-meters or joules
