Answer:
Step-by-step explanation:
x = -2x + 6
3x = 6
x = 2
y = 2(2)
y = 4
(2,4)
5 x 10⁻³ is a scientific notation.
5 is the coefficient
10 is the base
3 is the exponent. The sign of the exponent signifies which direction the decimal point moved.
negative sign means that the decimal point moved from left to right in writing the scientific notation.
positive sign means that the decimal point moved from right to left in writing the scientific notation.
5 x 10⁻³ is 0.005 in standard form.
had the exponent been positive.
5 x 10³ is 5000 in standard form
Answer:
D. (0, 7).
Step-by-step explanation:
Moving from (4,3) to (2, 5) we move 2 to the left; 2 - 4 = 2 then 2 up 3 + 5 = +2.
So the point C is 2-2, 5+2 = (0, 7).
Answer:
The kinetic energy of the roller coaster is 1600000 J.
Step-by-step explanation:
Given:
Mass of the roller coaster is 8000 Newton's and speed 20.0 meters/seconds.
Now, we need to find the kinetic energy of the roller coaster.
So, Mass of roller coaster (m) = 8000 N.
Velocity of roller coaster (v) = 20.0 m/s.
Now, putting the formula of kinetic energy:
Therefore, the kinetic energy of the roller coaster is 1600000 J.
