200000J/200KJ
Step-by-step explanation:
using k.e=1/2(mv2)
k.e=1×1000×20²/2
k.e=400000/2
k.e=200000J/200KJ
Answer:
The pre-image of the quadrilateral is attached.
Step-by-step explanation:
Each point (x, y) is rotated with the rule (x, y) -> (-x, -y).
So, point W'(2, 3) was W(-2, -3) before rotation.
X'(6, 3) was X(-6, -3)
Y'(6, 4) was Y(-6, -4).
Z'(3, 5) was Z(-3, -5).
The pre-image of the quadrilateral is attached.
Answer:
3y=x+5
Step-by-step explanation:
The slope of the line is (1/3). The equation of the line is y=(1/3)x+5/3 or 3y=x+5
Answer:
y = 7x - 2
Step-by-step explanation:
first we need the slope of the line.
the slope is expressed a the ratio (y coordinate change / x coordinate change) when we go from one point on the line to another.
so, let's say we go from (0, -2) to (1, 5), we see
x changes by +1 (from 0 to 1).
y changes by +7 (from -2 to 5)
so the slope is +7/+1 = 7
the slope-intercept form is in general
y = ax + b
a being the slope, b being the y-intercept (the y-value for x = 0).
the point (0, -2) gives us therefore the y-intercept directly : -2.
by using the already established slope and the point (0, -2) for the y-intercept the equation of our line is
y = 7x - 2
