Step-by-step explanation:
Given
Required
Determine the actual measurement of
Represent the required actual measurement with x
i.e.
And we have:
Cross Multiply
Convert fraction to improper fraction
Multiply both sides by 2

Answer:
Step-by-step explanation:
Given that ⊥
and
is the midpoint of
As ⊥
,
∠ and ∠
are right angles (Definition of perpendicular lines)
⇒∠≅ ∠
(All right angles are congruent)
T is the midpoint of (given)
⇒≅
(Definition of midpoint)
≅
(Reflexive)
Therefore, Δ≅Δ
(by SAS criteria ):

Answer:
Therefore after 1 second of lunched the object reach a height of 16 feet.
Step-by-step explanation:
When a particle is thrown vertically upward direction on that time only gravitation force is worked on it. In that case the acceleration of the particle is - g.Since gravitation force works downward direction and the displacement of the particle is upward direction that's why acceleration is negative.
When particle comes down the the acceleration of the particle is g.
Since the displacement and acceleration work on the particle in same direction.
The value of g is 9.8 m/s².
Given that, the height of the particle can measure from the equation
Where t is time in second
To find out the time when the object reach a height 16 feet. We have put the value of h in the given equation.
Putting h=16 in the given equation
16= -16 t²+32
⇒16t²-32t+16=0
⇒16(t²-2t+1)=0
⇒t²-2t+1=0² [ ∵16≠0]
⇒(t-1)²=0
⇒t-1=0
⇒t=1
Therefore after 1 second of lunched the object reach a height of 16 feet.
