First markdown reduces the item to 0.80×495=$396.
The second markdown reduces it to 0.90×396=$356.40.
The sum of the summers in the first column are 57
h is the plants hight and y is the plants age
A plants hight is 1.6 times it’s age
Equation: h = 1.6 y
Answer
h = 1.6 y
We know that
if two lines are perpendicular
then
m1*m2=-1
where
m1 and m2 are the slopes of the lines
step 1For <span>Y=(1/2)X-1
</span>slope m1=(1/2)
so
m2=-1/m1-----------> m2=-1/(1/2)-------> m2=-2
step 2
with m=-2 and the point <span>(2,5) find the equation of the line
y-y1=m*(x-x1)------> y-5=-2*(x-2)-----> y=-2x+4+5------> y=-2x+9
the answer isy=-2x+9
see the attached figure</span>
Answer:
4 m/s
Step-by-step explanation:
A bird is flying to the right when a gust of wind causes the bird to accelerate leftward at 0.5 m/s^2 for 3 s. After the wind stops, the bird is flying to the right with a velocity of 2.5 m/s.
Assuming the acceleration from the wind is constant, what was the initial velocity of the bird before the gust of wind?
Let say Initial Velocity of Bird = U m/s
Final Velocity of Bird V = 2.5 m/s
acceleration a = -0.5 m/s² ( as opposite to the fly direction)
Time T= 3 sec
Applying formula
V = U + aT
=> 2.5 = U + (-0.5)3
=> 2.5 = U -1.5
=> U = 4 m/s
the initial velocity of the bird before the gust of wind = 4 m/s
