Answer:
f(x)=x^2-12=0
x^2 =12
x= + or - sqrt(12)
x= 3.4641 or x= -3.4641
Step-by-step explanation:
Answer:
The original height of the tree is 18 m.
Step-by-step explanation:
Please see attached photo for explanation.
From the diagram, we shall determine the value of 'x'. This can be obtained by using the pythagoras theory as follow:
x² = 5² + 12²
x² = 25 + 144
x² = 169
Take the square root of both side
x = √169
x = 13 m
Finally, we shall determine the original height of the tree. This can be obtained as follow.
From the question given above, the tree was broken from a height of 5 m from the ground which form a right angle triangle with x being the Hypothenus as illustrated in the diagram.
Thus, the original height of the will be the sum of 5 and x i.e
Height = 5 + x
x = 13 m
Height = 5 + 13
Height = 18 m
Therefore, the original height of the tree is 18 m.
Answer:
3 gallons
Step-by-step explanation:
2 hours = 4 *3/4 hours
3/4 * 4 = 12/4 = 3
1/4(8/3 • 9) - 3
=3
I think this is probably the answer
Hello :
s = <span> |−13| = 13
the </span> inequalitie is not true is ; r ≥ s means : (r > s ) or ( r = s)
(r > s ) : <span>is not true
</span> ( r = s) : is not true
