Answer:
y = -47
Step-by-step explanation:
To find the midpoint of two points, add them together and divide by 2
(y+33)/2 = -7
To find y, multiply each side by 2
(y+33)/2 *2 = -7*2
y+33 = -14
Subtract 33 from each side
y+33-33 = -14-33
y = -47
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)
Answer:
False
Step-by-step explanation:
If we have a factor then the remainder after the division will be zero.
Ur independent variable is ur x values....ur dependent variable is ur y values..so if hrs are on the x axis, then ur independent values are ur hrs (or time)....and ur dependent values are ur distance.
(0,0),(2,50)
slope = (50 - 0) / (2 - 0) = 50/2 = 25
y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr
how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles
in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.
