Answer: Velocity needs both magnitude and direction
Step-by-step explanation:
Velocity is defined as a Vector quantity which implies that one needs to know both the magnitude and the direction of the object, as a reference frame. The expression for velocity is defined as:
Velocity = Distance * Time <=> V= dt
Acceleration occurs when an object initially moving with a constant velocity, changes motion and velocity increases with time. The expression for acceleration is defined as:
Acceleration = Velocity * Time <=> A= Vt
A typical example of acceleration is a Free Falling Object (i.e. letting a ball drop from a building)

sorry don't really know how to explain it rather than looking at the definition
Answer: she had 98 flowers
Step-by-step explanation: (4+3)x(7x2)
Answer: y=1/2x-3
Step-by-step explanation:
Slope-intercept form:y=mx+b
m=y2-y1/x2-x1
-1-(-2)/4-2=1/2
y=1/2x+b
-1=1/2(4)+b
-1=2+b
b=-3
