Answer:
No, it is not substitution property. Addition property of equality justifies the statement.
Step-by-step explanation:
The given statement: If
.... (1)
them
... (2)
According to the Addition property of equality, if a,b and c are real number, then
Using Addition property of equality, add 3 on both sides in equation (1).
This equation is same as equation (2).
Therefore Addition property of equality justifies the statement.
Given:
The two points on the graph.
To find:
The distance between the two points in simplest radical form.
Solution:
From the given graph, it is clear that the two points on the graph are (-9,3) and (-3,-2).
Distance formula:
Using the distance formula, the distance between two points (-9,3) and (-3,-2) is:
On further simplification, we get
Therefore, the distance between the given points is units.
Answer:
initial velocity = 64 m/s
Step-by-step explanation:
Differentiate H = 64t - 16t² to find an equation for velocity:
Velocity = = 64 - 32t
Initial velocity (u) is when t = 0:
u = 64 - 32(0)
⇒ u = 64 - 0
⇒ u = 64 m/s
