Answer:
x = 3
Step-by-step explanation:
ΔABC is 45 45 90 right triangle
The ratio of leg: hypo = a : a√2
Given: hypo AC = 6√2; so AB = BC = 6
ΔBCD is 30 60 90 right triangle
The ratio of short leg : long leg : hypo = x : x√3 : 2x
Hypo. BC = 6 = 2 (3)
So short leg BD = x = 3
The triangles are similar because two angles have the same measurements
Answer:
ok
Step-by-step explanation:
First you need to find out the remaining value after he bought the calculator this would be 14.67.
60.54 - 45.87= 14.67
Next youll assume the packs of notebooks all cost the same and divide by 3
14.67 / 3 = 4.89
He spent 4.89 on one pack of notebooks
Answer:
<em>The coefficient of the squared expression in the parabolas equation will be 5.</em>
Step-by-step explanation:
<u>The vertex form of parabola</u> is: 
, where 
is the vertex point and 
is the coefficient of 
term.
The vertex is given as 
. That means, 
and 
So, the vertex form will be: 
Given that, when the x-value is 4, the y-value is 3. So, plugging these values into the above equation, we will get.....
Thus, the coefficient of the squared expression in the parabolas equation will be 5.
